RHI Breaks the £9 Million Barrier, Biomass Boilers Maintain Lead!

Tuesday, April 30th, 2013

The Renewable Heat Incentive (RHI), which pays the owners of biomass boilers for generating and using renewable heat, has now broken the £9 million barrier in terms of payments made to date.

RHI Compliant Biomass Boiler

RHI Compliant Biomass Boilers from Treco

A total of 1,358 projects have been accredited as of today and total payments of £9,057,397.19 across all technologies including biomass boilers have been made to date.

The majority of installations have been in England, some 75.18% of the total, with 18.41% in Scotland and 6.41% in Wales.

Biomass boiler installations continue to dominate the scheme, with 91.56% of total installs and 99.56% of overall capacity being for biomass.  This in turn gives a breakdown of 74.56% of RHI accredited biomass boilers being in England and 19.09% being in Scotland and 6.15% being in Wales.

New Case Study Online! Biomass District Scheme Heats 16th Century Farmhouse, Food Processing Unit and Workshops on the Killerton National Trust Estate

Tuesday, April 30th, 2013

Yarde Farm is a 350 acre beef and arable enterprise based on the Killerton National Trust Estate in Devon. With the farmland including over 200 acres of flood plain in permanent pasture, a Higher Level Stewardship has been introduced to help manage a wide range of challenges.

Biomass Boiler at Yarde Farm

The farmer was keen to use his wood fuel supply to reduce heating costs and to be self sufficient. The installation needed to be compliant with Renewable Heat Incentive (RHI) eligibility criteria.

A single 100kW Guntamatic Powerchip biomass boiler and mini district heating scheme replaced the oil boilers. The buildings were linked using insulated underground pipe.

The boiler was installed in a barn located 100 metres from the other buildings in the scheme. The boiler’s fuel store has been constructed to enable wood to be chipped directly into the fuel store or loaded by a handler.

Wood grown on site is contract chipped into fuel store and the system provides heating to 16th Century listed cob farm house, workshops and food processing unit as well as hot water to farm buildings in mini district heating scheme.

The Hidden Cost of Poor Quality Fuel for Use in Biomass Boilers

Wednesday, April 24th, 2013

We’ve seen a rise in problems related to the use of poor quality wood chip and wood pellet fuel in our biomass boilers. Although Treco does not supply wood fuel, we know lots of people that do and thought that we would write a feature to highlight the issue and to offer some tips and guidance.

The Benefits of Using Good Quality Fuel in Biomass Boilers

1.    Fuel Cost Saving of up to 80%

When the correct grade and quality of wood fuel is used in Treco’s biomass boilers, fuel cost savings of up to 80% versus fossil fuels has seen our clients save a lot of money by moving from oil or LPG to biomass.

2.    The Best Performance from your Biomass Boiler

In addition, when the correct grade and quality of wood fuel is used the performance of the boiler is maximised, enabling peak efficiencies of up to 96% to be achieved and the most heat for your money to be delivered from your biomass boiler.

3.    Sustainable and Renewable

Unlike our supplies of oil, LPG and mains gas, quality assured biomass fuel is sustainable and renewable so offer futures fuel security in the face of dwindling reserves of fossil fuels.

4.  CO2 Saving of Up to 98%

Biomass fuel per se also offer a CO2 reduction of up to 98% versus electricity and 96% versus oil and LPG. So, for those simply wishing to reduce their carbon footprint, biomass offers an easy way to do so.

Biomass benefits for code for sustainable homes

5. Planning, Code for Sustainable Homes, Building Regulations and the RHI

With such significant CO2 savings and such low emissions from the Guntamatic Powerchip, BMK, Biostar and Biocom biomass boilers, there are a range of benefits to those involved in new build.

These range from ease of planning, to compliance with the new maximum emission levels soon to be introduced (summer 2013) in the Building Regulations to gaining advantages in Code for Sustainable Homes Developments. See our overview of how biomass offers advantages in Code for Sustainable Developments here;  www.treco.co.uk/blog/why-biomass-offers-advantages-for-code-for-sustainable-homes-developments/

The new emission levels to be applied in the Building Regulations will be a maximum of 30g/GJ particulate matter and 150g/GJ nitrogen oxides and this will also be a requirement for all new applications for inclusion in the Renewable Heat Incentive (RHI).

6.    Peace of mind and an Easy Life

Good quality wood fuel, combined with a robust, efficient and automated fuel delivery system to the biomass boiler, will ensure ease of use and will make switching to biomass from fossil fuels straightforward for the user. Done correctly and with the right biomass boiler system should involve no more effort by the user than will oil or LPG, but can require more effort if done badly.

Problems with Poor Quality Fuel

However, the use of poor quality fuel is one of the most common issues that can result in Treco’s biomass customer support being called out to investigate faults on site. The most common issues that poor quality wood fuel can cause include the following, although the list is not exhaustive;

  • Reduced boiler performance; burning off water which means a higher unit cost to generate the same amount of heat.
  • Contaminated fuel increasing your carbon footprint, particularly if you are located in a UK Smoke Control Area.
  • Fly ash can be generated which is hot and can cause flammable materials to catch fire or injury to persons.
  • Poorly constructed and maintained fuel stores containing stones or areas where moisture/ rainwater can enter and reduce the quality of the fuel or require more time to reduce moisture below acceptable levels.

The Characteristics of Good Quality Fuel
The characteristics of good quality biomass fuel vary, depending on the type of fuel but a general rule is that the fuel should be free from contaminants, metals or any other pollutants and not be “wet” or have excessive moisture content. Great care must be taken when planning to use wood waste to ensure it does not feature nails, glues or other contaminants. For this blog, we have focussed on logs, wood chips and wood pellets.

wood burning boiler - logs to use

Logs for biomass boilers

1.    Logs

For use in the Guntamatic BMK www.treco.co.uk/list-products/BMK/ , logs should not be burned until they have been adequately seasoned so they have moisture content below 20%. It is ideal to have no nails, barbed wire or contaminants such as tanalised coatings or preservatives as this will add to the boiler’s emissions, as opposed to delivering the high up to 98% CO2 savings that biomass can offer compared to fossil fuels.

Hard woods will take longer to season (roughly 2 years) than soft woods (1-1.5 years) and the ideal size for use in the BMK log boiler is 500m in length and 12-15cm thick.

Coarse wood chips (above G30) can be used in the Guntamatic BMK, but it is important to always cover each load of coarse wood chips with a layer of logs and to always refill with a layer of logs before a layer of coarse wood chips.

Contract Chipping for Biomass Boilers

Contract Chipping for Biomass Boilers

2.    Wood Chips

The Guntamatic Powerchip www.treco.co.uk/list-products/Powerchip/ , which also burns wood pellets, grain and chopped or pelleted miscanthus, is designed for burning G30 wood chips, with an average wood chip size of 3mm and a maximum moisture content of 30%. It is not advisable to burn wood chips with a significant percentage of water as energy that could otherwise be used to generate heat is used to burn off the water in the fuel.

Wood chips then generally fall into 2 categories – bought in or contract chipped on site.

Bought in Wood Chips

If buying in wood chips, care must be taken to select a supplier who can give you assurances of quality, such as being approved by HETAS www.hetas.co.uk/consumer/fuel-quality/ against the Woodsure www.woodsure.co.uk/producer_intro.htm or ENplus www.enplus-pellets.eu/ fuel quality standards.

A good starting point is to view the Carbon Trust and Biomass Energy Centre’s National Biofuel Supply Database. Their interactive map enables you to zoom in and locate suppliers in your area and filter by both fuel type and either Accreditation by ENplus or Woodsure. We like it so much we have included it on the Treco website; www.treco.co.uk/fuel/

It is also important to visually inspect any delivery of wood chips to ensure that it does not contain nails, barbed wire, animal carcases or other contaminants that may reduce the performance of your boiler. A moisture meter can also be a great way of establishing if your wood chips have the ideal below 30% moisture content.

Contract Chipped on Site

If you have your own supply of wood fuel, the largest savings of up to 80% versus fossil fuels can be made, with prices of £50 per tonne being achievable. However, there are a range of considerations relating to quality. Firstly, the wood fuel needs to be seasoned so that moisture levels are below 30%. The time taken to season the wood fuel can be between 1-2 years, with hardwoods taking longer to season than softwoods. Once the logs are seasoned and dry enough to burn efficiently, a large number of our clients are making use of the contract chipping service that a number of local suppliers offer. However, it is very important to ensure that the chipping machine that the supplier uses enables fuel quality chips to be made, which conform the G30 fuel standard.

Whether you buy in or chip your own wood fuel, further consideration needs to be given to fuel storage. The fuel store needs to be regularly swept (just before refill) in order to ensure there are no stones or other foreign objects that may reduce the boiler’s performance. Additionally, the fuel store needs to be set up so that water cannot enter and there is sufficient ventilation to allow your wood fuel to breathe. There are other considerations, so do take a look at our fuel delivery systems, which give a range of other tips and bits of advice. http://www.treco.co.uk/fuel-stores/

Wood pellets for biomass boilers

Wood pellets for biomass boilers

3.    Wood Pellets                                 

They should be dry, clean, mechanically robust and to the appropriate fuel grade standard, with no additives or binding agents. Wood pellets are generally made from sawdust, with their structural integrity achieved by compression at the pellet processing plant. Treco’s biomass boilers require 6mm diameter wood pellets to the EN14961 fuel standard and with a maximum moisture content of 10%. We recommend only using quality assured suppliers, to get the most heat for your money.

For use in the Guntamatic Biocom  www.treco.co.uk/list-products/Biocom/ , the ideal characteristics of wood pellets should be 5-30mm in length and 5-6mm in diameter, with a water content of 8-10% and ash content of 0.5%. This gives a bulk weight of 650kg/m3 and 4.9kWh per kg.

Wood pellets should also be mechanically robust, with to avoid disintegration, with a hard and shiny surface, to enable them to easily flow through the boiler’s fuel delivery system. If the wood pellets are not, they may turn into dust, which will not work well in the boiler.

As a general rule, wood pellets should be stored in absolutely dry storerooms, with adequate ventilation and the appropriate levels of fire protection. There are other considerations, so do take a look at our fuel delivery systems, which give a range of other tips and bits of advice. http://www.treco.co.uk/fuel-stores/

We will be blogging other tips and advice regarding wood fuel supply over the coming months, so do watch this space!

Twin Wall Flue Systems for Biomass Boilers

Tuesday, April 23rd, 2013

There are a number of considerations for designing the flue system for a biomass boiler installation. Our project management team will manage this for Treco customers, but some important considerations are listed below. We fit Twin Wall, Insulated stainless steel multi-fuel chimney systems for Treco installs, which are eminently suitable for modern biomass boiler applications.

However, please contact us on 0845 130 9012 or email us at info@treco.co.uk to discuss the flue requirements for your biomass boiler project.

Twin wall flue systems for biomass boilers

Twin wall flue systems for biomass boilers

Regulations

All twin wall flue systems for biomass boilers (including log boilers, wood chip boilers, wood pellet boilers) must be installed to comply with Document J of the Building Regulations in England and Wales and part F of the Building Regulations in Scotland, as well as to the flue manufacturer’s installation instructions.

Flue Design

The biomass boiler twin wall flue system, from the point it leaves the building, should remain as straight as possible and be high enough to ensure sufficient draught to clear the products of combustion. The height necessary for this will depend upon the type of the appliance, the height of the building and the number of offsets within the system. However, a minimum flue height of 4.5 metres should is recommended in the Building Regulations.

Where it is not possible to construct a vertical flue for your biomass boiler system, Building Regulations dictate that no part of a chimney should form an angle greater than 45° from the vertical, except where it may be necessary to use a very short horizontal section, not exceeding 150mm, of flue to connect to a back outlet appliance. The run between offsets should not exceed 20% of the overall height of the chimney. In both instances, a maximum of two offsets in any one flue run should be used. Cleaning access must be provided in chimney systems with two offsets. It is also recommended that a vertical rise of 600mm should be allowed, immediately above the appliance before any change of direction.

Where the flue passes through a combustible floor or ceiling, an air gap clearance as per the manufacturer’s installation instructions is required. In multi-fuel applications and where the flue gas temperature is greater than 250°C, the ventilated fire stop and ventilated support components must be used at the bottom and top of the shaft. No joints can be made within the thickness of any floor or ceiling joists. The twin wall flue system must project below the ceiling in accordance to the diameter of the flue pipe.

Use of an adjustable length within the flue pipe connection or twin wall flue system immediately above the appliance enables removal of the appliance later without dismantling the full system.

In the room where the biomass boiler appliance is installed, provision should be made for an air vent. This is required to provide adequate air supply to allow the appliance and flue to operate efficiently. These requirements are specified in the Building Regulations. Where a flue passes through an external wall, a wall sleeve must be used.

Flue Size

The size of the chimney system should be as recommended by the biomass boiler appliance manufacturer’s installation instruction and in most cases should not be smaller than the appliance outlet. Confirmation from the manufacturer will be required if you wish to reduce the flue size. Flue sizing for commercial biomass boiler applications will depend on individual site details and must be designed and sized in accordance with manufacturer’s criteria. For open fireplaces and inglenooks with openings larger than 500mm x 550mm, a flue size with a cross sectional area equal to 15% of the total face area of the fireplace opening is required. On multi-fuel or wood burning closed biomass boiler appliances of up to 30kw rated output, the minimum flue size must be a 150mm internal diameter.

Support Components

Load bearing supports eg. wall supports and ceiling/joist supports are required to take the vertical weight of a twin wall flue system.  Non load bearing supports eg. wall bands and roof/rafter supports give lateral support throughout the chimney system. Wall bands should be fitted every 3 metres and where the flue offsets to ensure the system is adequately supported. Where the flue is free standing above the roof line a height of up to 3 metres can be achieved unsupported with the use of a reinforced or extended locking band at the joint immediately below and every joint above the roof level.

Twin wall flue systems for biomass boilers

Provision for sweeping, cleaning and maintenance

Provision should be made for inspecting and cleaning the flue. This is particularly important on solid fuel applications. It is recommended that flues serving solid fuel appliances be swept and maintained as frequently as necessary but at least once a year.

Please contact us on 0845 130 9012 or email us at info@treco.co.uk to discuss the flue requirements for your biomass boiler project.

The Benefits of Biomass Boiler District Heating

Monday, April 22nd, 2013
Biomass Boiler District Heating

Biomass Boiler District Heating

Biomass boiler district heating applications are where several buildings or zones are heated by a single biomass boiler (or wood burning boiler, log boiler, wood chip boiler or wood pellet boiler) via a heat “network”.

This involves circulating hot water to several buildings or “Zones” via underground, pre-insulated pipes (also called “heat main”).

The heating circuit within each building or zone is isolated from the biomass boiler which provides the main source of heat, with no combustion occurring at the point of use. Instead, a control system such as a Treco Consumer Interface Unit is used in place of a biomass boiler, which offers all the control that a full boiler would give at the point of use, but in a far smaller package.

Gunt_powerchip_75_100

Key Benefits

There are a number of advantages to biomass district heating.

Fuel Cost and CO2 Savings Magnified

Biomass per se offers CO2 savings of up to 96% and fuel cost savings of up to 80% versus fossil fuels. District heating with biomass can drive further economies of scale and exponentially lower emissions than with multiple localized boilers. Where the installation can be on a scale of 50-400kW, this can become highly environmentally and economically beneficial with savings multiplied across multiple units, buildings or zones.

Biomass Boiler District Heating

Biomass Boiler District Heating Fuel Cost Savings

Building Regulations, RHI and Code for Sustainable Homes Compliance

For housing developers, these CO2 savings will give a significant advantage in Code for Sustainable Homes Developments and easy compliance with Document J of the Building Regulations (Combustion appliances and fuel storage systems) and Document L of the Building Regulations (the Conservation of fuel and power).

The lower carbon footprint synergies of a high efficiency biomass boiler heating several zones of buildings, the use of renewable fuel and district heating combined can also ensure easy compliance maximum emission levels. The tougher maximum emission levels soon to be introduced in the Building Regulations and the accreditation criteria for entry into the Renewable Heat Incentive are due to come in during summer 2013 will specify maximum emissions of 30g/GJ particulate matter and 150g/GJ nitrogen oxides.

Commercial Landlord Advantages

Biomass district heating offers commercial landlords the opportunity to sell low cost heat to tenants or to sell biomass heat at a profit.

These stem from the heating circuit within each building or zone being isolated from the biomass boiler providing the main source of heat.

Heat usage levels can be monitored by the quantity of hot water used in the relevant zone being measured via a heat meter. This allows delivered heat to be accurately and easily billed.

Tenanted properties which are heated by renewable energy can also be easier to let and to keep let, with less time left unoccupied and not generating rental income.

Heat Metering for Biomass Boiler District Heating

Total control – Heat Metering for Biomass Boiler District Heating

Control and Safety at the Point of Use

With combustion only occurring centrally, the occupants or tenants in each individual zone are given a safe environment in which to live or work, with no annual safety checks, carbon monoxide alarms or health and safety provisions required at the point of use. This gives tenants all of the controls they would expect from a full boiler system, but in a smaller and safer package.

This makes biomass district heating advantageous for use in care homes, social landlords, hospitals, schools or any other applications where the owners, Energy Service Company (ESCO) or maintenance provider will have a legal duty of care and safety to building occupants.

Ease/Lower Costs of Maintenance and Servicing

In addition, district heating offers a range of administrative benefits, time and cost savings, as well as huge potential maintenance and servicing advantages.

Money for Green Heat; The Renewable Heat Incentive – Available for Domestic Properties NOW!!!!

Installations featuring a single boiler serving a single domestic property will not be eligible for the Renewable Heat Incentive (RHI) until April 2014.

However, district heating can offer homeowners access to the fuel security and generous payments that commercial, non-profit, public sector and charitable organisations currently enjoy. Where a single boiler serves more than one property (i.e with more than one Council Tax Account), the installation will be deemed as commercial and will be eligible for 20 years of payments from the commercial RHI, which has been available since November 2011.

RHI Compliant Biomass Boiler

RHI Compliant Biomass Boiler

Remote Control

Remote meter reading and heating control by web based applications or GSM are possible, as are remote diagnostics to ensure reliable operation. This can provide landlords (who have multiple tenanted properties) with ease of management, particularly if their properties are in different geographic locations. This can offer time and financial savings from not having to travel to remote locations.

In addition, with no fuel usage at the point of use, landlords can continue to provide warmth and comfort to tenants during extreme weather conditions, when a fuel delivery may not be possible and to provide a service to tenants which avoids the effort of them handling fuel.

Renewable Biomass Energy Revolutionises Poultry Production

Friday, April 19th, 2013
Poultry House Biomass

Biomass reduces farm input costs at Hollyfield Farm

Article Written by Les Heywood, Hollyfield Poultry Farm. Check out the case study and find out how a 300kW biomass boiler solution at Hollyfield farm heats 5 poultry houses and farmhouse, improves bird welfare and saves money on farm input costs

www.treco.co.uk/case-study.php?UUID=13627368695095

As with most types of farming production in the UK, the poultry meat industry is challenged with tight margins and ever-increasing input prices. Rising energy costs place a particular demand with heating being one of the most critical and expensive inputs.

The typical design of a modern poultry building requires a floor space large enough to grow birds from day old chicks to full slaughter weight. With chicks delivered straight from hatchery to farm for whole house brooding, the critical temperature needed of around 32oC requires a constant heat input. The result is the consumption of large quantities of fossil fuels needed to heat the whole air and floor space (typically via LPG fired in-house heaters).

As well as the financial demand on farmers, a further factor of direct heating is the by-products of combustion which are placed inside of the poultry house, creating a less than perfect environment for chicks and stockman alike. When propane (LPG) undergoes combustion, both carbon dioxide and water are created. After a few days, poultry houses will need to be regularly ventilated to remove CO2 , necessitating further heating to warm the incoming fresh air. Water increases humidity levels deteriorating litter quality if not managed correctly.

In stark contrast, many poultry farmers are now starting to reap huge benefits in more ways than one from conversion to indirect ‘renewable’ heating systems. Made financially viable by the governments renewable heat incentive (RHI) scheme launched in November 2011, capital investment are now being made into complete biomass heating.

A biomass boiler (fuelled typically by woodchip) heats water remotely which is then piped underground into poultry houses to be converted into warm air through heat exchangers. The dry and indirect heat has massive benefits to the environment within the poultry house and ultimately, bird welfare. Production of CO2, carbon monoxide, and water is eliminated from heating, so air and litter quality are greatly improved. Ventilation is more manageable and an ideal house environment can be easily achieved throughout the year. Lower humidity levels can be achieved throughout the complete bird cycle to maintain a higher litter quality. This has benefits both financially (reducing the cost of bedding by eliminating top-ups) and  to bird welfare.

IMAG0215 for web

With the retail industry becoming increasing committed to the reduction of carbon footprints in the food supply chain, CO2 savings of up to 97% from biomass versus LPG are another important benefit.

The government RHI scheme pays the owners of eligible commercial renewable technologies (which include wood burning boilers and biomass heating) for the heat they generate and use. The returns are not insignificant. As an example, a farm with a 100kw system could expect to gain upwards of £11,000 a year, every year of the RHI scheme, index linked to inflation. For full conversion from LPG to biomass heating, typically 1kw of biomass generated heat will heat 8-10m2 of poultry floor space.

Combining fuel cost savings from potential on-farm wood chipping, reduced bedding costs, the indirect performance benefits from growing birds in an improved environment, and a guaranteed 20 year RHI payment scheme, farmers can typically expect payback periods in the region of 5-6 years (including finance costs).

Over a number of years, Treco have gained a proven track record in biomass solutions and are experienced in complete end to end solutions for poultry house heating.

UKDEA Welcomes Government’s Heat Policy Proposals But Questions Whether They Go Far Enough

Wednesday, March 27th, 2013

logoblackbanner4p
UKDEA welcomes Government’s heat policy proposals but questions whether DECC have gone far enough to deliver the required growth in low carbon heat networks.

DECC today released its latest salvo of proposals to decarbonise the nation’s heat supplies.

Heading up the charge of the Department of Energy and Climate Change’s developing Heat

Strategy was their new policy document titled “The Future of Heating: Meeting the

challenge”. Following on from last year’s “Strategic Framework for Low Carbon Heat”, this

action plan has done well to translate loose aims into concrete policy proposals, though

there will plenty of work to do, to turn these proposals into successful action.

Heat is responsible for about a third of UK’s greenhouse gas emissions and it’s clear that

DECC still have the necessary ambition for low carbon heat in the UK; Secretary of State,

Ed Davey, stated in his forward, “Without changing the way we produce and consume heat,

we will not meet our long-term climate change target.”

 

District energy remains central to the Government’s low-carbon heat policies, with one of the

policy paper’s four chapters devoted to Heat Networks. Also considered are uses of Low

Carbon Heat in Industry, Heat and Cooling in Buildings, as well as Grids and Infrastructure.
UKDEA Chairman, Simon Woodward, said earlier “We are delighted that the Department of

Energy and Climate Change recognise greater use of low carbon district energy is a

necessity for this country, and we are very positive about the announcements today.

However, we’re left waiting until 2014 before consultation commences on any fiscal support

for implementation and therefore, we question whether the growth DECC are seeking will be

delivered by this policy paper when only development and not capital cost implementation

barriers are being addressed. We will of course continue to work with Government, to

identify ways to overcome these barriers and rapidly expand district energy networks in the

UK”.


What are the Proposals?

The flagship heat networks policy proposal is a new Heat Networks Delivery Unit (HNDU),

operating within DECC, providing support to local authorities that want to deliver district

energy schemes. HNDU will work closely with local authorities’ project teams, providing the

expertise that they may lack in-house. As part of this £9m programme, a total of £6m will be

available (for up to two financial years) to support early stage development costs and ready

projects for procurement.
However, at this stage, no funding or financial support is available to support capital costs of

delivering schemes. Although next year, DECC will look at the potential to provide

renewable heat networks with specific financial incentives, through the Renewable Heat

Incentive (RHI). This is welcome news, even though the initial aim had been to include such

support in the RHI from the start and further delay to consultation in 2014 remains

frustrating.
DECC intends to endorse industry-led consumer protection later this year and will also

consult on options for mandatory installation of heat meters as part of heat network

developments. DECC has continued to make clear that it does not wish to stop the growth

of the UK’s district energy sector through unnecessary regulation.
The DECC Policy Paper draws heavily on quantified evidence, including referenced

contributions from the UKDEA. Results from the recent Databuild research are included,

which estimated that there are around 2,000 DH networks in the UK, serving approximately

210,000 dwellings as well as 1,700 commercial and public buildings, all delivering around

2% of national heat demands. BRE’s recent work for DECC on barriers to District Heating

informs the proposals and is covered in more detail in a separate paper, also released today,

that is over 100 pages long. A further 48 page long Evidence Annex adds to the evidence

base.
The UKDEA will spend time considering the supporting evidence and ensure that any

necessary peer review forms part of our response to Government, alongside continuing

advice and submission of relevant evidence. Analysis of the policies will be carried out with

the input of the UKDEA’s diverse and experienced member base, so that the genuine

potential of the proposals can be understood.
Further Government action in this area isn’t limited to Whitehall and the UKDEA also eagerly

DECC publishes the Government’s Heat Strategy – Government Sets Out Plans To Cut Emissions From Heat

Tuesday, March 26th, 2013

 

DECC publishes the Government’s Heat Strategy and provides an update on the Renewable Heat Incentive

Read the Full Press Release Here;

One year on from the launch of the UK’s first ever heat strategy, the Government has today set out the next steps to ensure affordable, secure, low carbon heating plays an important role in the nation’s energy mix, now and in the years to come.

The scale of the challenge is huge, with over 80 per cent of heating used in UK homes, businesses and industry produced by burning fossil fuels, and over a third of the UK’s carbon emissions coming from the energy used to produce heat.

The Government is committed to driving forward the move to low carbon alternatives to cut carbon and help meet renewables targets, and the heat strategy and its follow on action plan published today are an integral part of this vision.

Energy Secretary Edward Davey said:

“If we can increase the use of low carbon heating in our homes, businesses and across our economy, we can help reduce our dependence on costly carbon intense fossil fuels.

“Last year we launched the UK’s first ever heat strategy, to get us on the right pathway to decarbonisation and today we have published an update on the progress we have made so far, alongside a new set of actions specifically targeted at industrial heat, urban heat networks and heat in buildings.

“Many homes and businesses across the UK have already switched away from fossil fuels and are using kit like biomass boilers, heat pumps and solar thermal panels to provide heat, thanks to Government support, and I want to ensure even more householders and organisations get on board.”

Today’s action plan looks at the potential to cut emissions from heat across the whole UK economy and focuses on a number of key actions to spur on the move to low carbon heating alternatives and drive forward green growth, including:

  • A £9million package to help local authorities get heat network schemes up and running in towns and cities across the country, with a new Heat Networks Delivery Unit to sit within the Department of Energy and Climate Change (DECC) providing expert advice.
  • £1million for the cities of Manchester, Leeds, Newcastle, Sheffield and Nottingham to help them develop heat networks
  • 100 green apprenticeships to be funded primarily for young people in small scale renewable technologies
  • Up to £250,000 for a new first come first served voucher scheme for heating installers to get money off the cost of renewable heating kit installation training, with up to £500 or 75 per cent of the cost of the training course per person
  • Working with individual industrial sectors to design long term pathways to cut carbon across UK industry

There are also a number of helpful low carbon heat case studies in the action plan, including the first ever biomethane installation accredited under the RHI in Poundbury, Dorset; Aspire Housing’s work to install low carbon heating in the homes of 56 social tenants; and the gas CHP plant which provides heat to the 72 storeys of the tallest building in Western Europe, the Shard in London.

Update on renewable heat schemes

The Renewable Heat Incentive (RHI) scheme, launched for industrial and commercial customers in November 2011, is a key part of the Government’s approach to cutting carbon and spurring on the uptake of renewable heating kit. As recently announced, DECC is planning to carry out a review of the tariffs under this scheme to drive forward further uptake and has today set out which technologies will be included in this review.

Energy and Climate Change Minister Greg Barker said:

“The Renewable Heat Incentive, which has been available for non domestic investors for over a year, is a key part of our approach to cutting carbon and driving forward the move to more sustainable low carbon heating alternatives.

“So far over 1,000 groups have got on board, and today we have outlined details of our tariff review to help encourage even more organisations to invest.

“We remain committed to introducing an incentive scheme for householders too, and have today set out an updated timetable for its launch alongside plans to extend our renewable heat voucher scheme in the meantime.”

  • Non domestic RHI tariff review: DECC plans to consult on increased tariffs for some technologies where the evidence suggests a change needs to be made. The tariffs and technologies to be included in the review are available online.
  • Expanding the non domestic RHI: DECC consulted on expanding the non domestic RHI scheme to include further technologies in September 2012 and will confirm the way forward in Summer 2013.

The Government remains committed to introducing an RHI for householders, and has today set out an updated timetable for its launch alongside plans to extend the Renewable Heat Premium Payment (RHPP) in the meantime.

  • RHI for householders: Following on from the consultation on scheme design in September last year, the Government will confirm how a RHI for householders will work and publish the tariff levels in Summer 2013. It is expected that the scheme will be up and running for householders in Spring 2014. Research on householder views on renewable heat has also been published today, which will help inform the design of the RHI scheme.
  • RHPP extension: The Renewable Heat Premium Payment (RHPP) scheme is being extended until the end of March 2014, ahead of the launch of the RHI for householders. This scheme, first launched in July 2011, offers money off the cost of renewable heating kit such as biomass boilers, solar thermal panels and heat pumps and is largely targeted at those living off the gas grid. The scheme was due to close at the end of March this year.

Notes;

  1. The heat strategy policy document
  2. The research published today on perceptions of renewable heat
  3. The renewable heat training money off voucher scheme will support biomass, solar thermal, air and ground source heat pumps technologies and is being offered on a first come, first served basis to UK employers, with a particular emphasis on small and medium sized enterprises (SMEs). There is a maximum of £500 or 75 per cent of the cost of a training course available per person. Employers can apply for up to five vouchers and it is up to employers how they are allocate these amongst employees. The vouchers must be used for courses based on the Qualification Credit Framework Units derived from National Occupational Standards. There are a number of training providers and organisations that are able to offer such provision. Vouchers must be redeemed for a training course within three months of registering. More details on how to apply will be available online soon.
  4. The new £250,000 green apprenticeships programme will run for three years, with DECC funding offered in years one and two, and up to £2500 available funding per apprentice. More details will be available online soon.

  6. More details on the extension of the RHPP scheme will be available shortly on the Energy Saving Trust website.

Why Biomass Offers Advantages for Code for Sustainable Homes Developments

Biomass and the Code for Sustainable Homes (CSH)

Background

The Code for Sustainable Homes is the national standard for the sustainable design and construction of new homes. The Code aims to reduce our carbon emissions and create homes that are more sustainable in the long term.

Benefits of CSH Certification
With a more environmentally-conscious public, aware of the urgent need to limit their
effects on climate change, there is a growing appetite amongst consumers for more sustainable products and services. With greater demand for homes that offer reduced environmental impact, lower running costs and features that enhance health and well-being, there is an increased need for home builders to demonstrate their capacity in sustainable home building, and to market the sustainability of their homes to homebuyers. The Code offers a tool for home builders to demonstrate the sustainability performance of their homes, and to differentiate themselves from their competitors. The Code is also mandatory of new build public sector projects and for developments over £300,000.

How the Code For Sustainable Homes Works

csh table 3

The Code measures the sustainability of a new home against categories of sustainable design, rating the ‘whole home’ and its Total Efficiency Rating (TER) as a complete package. The sustainability categories by which new homes are measured are outlined below, along with the relative weightings and points available.

The Rating System

The code works by awarding new homes an overall efficiency rating from Level 1 to Level 6, based on their performance against the 9 sustainability criteria above. These are combined to assess the overall environmental impact of the dwelling. The levels of energy efficiency are the standard percentages set out in Part L1A of the 2006 Building Regulations) http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADL1A_2006.pdf

Note; The maximum emission levels set out in PartL1A of the 2006 Building Regulations is changing in summer 2013 to 30g/GJ particulate matter and 150g/GJ nitrogen oxides 30mg/Mj. This will also become the standard requirement for inclusion of a biomass boiler project into the Renewable Heat Incentive.

The code levels, based on minimum percentage reduction in Dwelling Emission Rates over Target Emission Rates are;

csh table 2

To reach CSH Code Levels 5 & 6, the architects have designed the properties to be airtight, with high levels of insulation and many sustainable features including low water use, roofs designed to maximise solar PV energy collection and biomass boilers.

To reach the different code levels, a quantity of points is required;

csh table

Biomass and the Code for Sustainable Homes

Biomass can be very beneficial to CSH Projects, as the Energy and Carbon Emissions Category Number 1 carries the greatest overall weighting of all the factors at 36.4%.

The Biomass Energy Centre shows that biomass as a fuel type offers the highest CO2 reductions against fossil fuel types of 96-98%;

Treco-Table for web smaller

So, if a high 92%+ efficiency biomass boiler is installed in a new build project, with emissions below 30g/GJ particulate matter and 150g/GJ nitrogen oxides 30mg/Mj, it can contribute towards and increase the overall CSH Level of the project to Code 5/6 level.

However, an architect or suitably qualified building professional should be consulted in order to assess the specific CSH values of your project, as this is a highly specialist area.

REA Publishes First Ever Renewables Industry Confidence Survey

Monday, March 18th, 2013

The REA has published the first ever renewables industry confidence survey, please read the press release below

Modest optimism short term, but some doubts over key policies. Overall score: 47%

The REA has conducted this survey in order to better understand the current state of the UK renewable energy sector [1].

The survey takes place at a time of major policy upheaval for the renewable power and renewable transport sectors and follows several analyses suggesting that investment in the renewables project pipeline has slowed [2]. This morning’s Financial Times [3] reported the concerns of REA members responding to the survey about the new Contracts-for-Difference mechanism under the Energy Bill.

Senior managers from 68 companies responded to the survey. Findings confirm the Energy Bill is cause for concern with 51% of renewables executives believing that Contracts for Difference will not be effective in bringing forward new renewable power capacity. 69% believe that the lack of an emissions target in the Energy Bill sends a ‘poor’ or ‘very poor’ signal to investors. Only 4% believe the UK has a ‘good’ or ‘excellent’ chance of meeting its 2020 renewable energy target.

However, the survey shows no significant overall deterioration in employment over the past six months. Just under a half of companies reported broadly stable employment levels and nearly as many firms recruited staff as have laid them off. Looking forward over the next six to twelve months 62% of companies expect employment levels to stay the same, and twice as many firms expect to see employment increasing, compared to those expecting a decrease in employment.

REA Chief Executive Gaynor Hartnell comments:

“We will repeat this survey every six months in order to build up a comprehensive picture showing trends in confidence levels. Billions of pounds of investment needs to flow into renewables infrastructure. Our aim is to provide Government and stakeholders with a tool to gauge how policies are being received.

“The UK has to achieve a higher growth rate than any other Member State in order to reach its 2020 renewables target. Mixed messages remain a problem and industry needs policy certainty and political consistency. The prize is up to 400,000 jobs by 2020, economic growth and greatly improved energy security.

The REA has combined short term business outlook with confidence in meeting the 2020 target and confidence in the regulatory framework to give an overall ‘Renewables Industry Confidence Index’.

The ‘Renewables Industry Confidence Index’ score for this first iteration of the survey is 47% [4].

r

While 100% would constitute absolute certainty and a flourishing industry, we believe a score of around 75% would indicate a healthy and confident industry likely to meet the 2020 renewable energy targets. The UK has one of the lowest renewable energy targets in Europe at 15% of total energy, but also one of the most challenging given our low starting point.

The survey reveals serious concerns around Contracts for Difference, as set out in the Energy Bill, and dissatisfaction with the functioning of the Renewable Heat Incentive. It also makes key recommendations for improving investment going forward, including sending a clear signal to investors; ensuring CfD proposals in the Energy Bill work for independent generators; setting an RTFO trajectory to 2020; and introducing new RHI tariffs on time.

A selection of comments from survey respondents is set out below to illustrate industry perspectives.

General comments on UK policy and political landscape

An anonymous respondent from a leading UK manufacturer said:

“Too many conflicting signals have been given recently causing doubt as to whether the Coalition has a unified position on promoting a balanced mix in the future UK energy supply, including renewable technologies. There is also doubt that the Government is convinced that renewables have a long term role to play, and a widespread belief that HM Treasury has the upper hand in determining the ultimate rate of market adoption of renewables.”

An anonymous financier said:

“There is no shortage of capital for energy projects but it is an international market and many other countries are perceived as more predictable and trustworthy than the UK.”

Craig Ibbetson, Director of Regen Energy, said:

                “Simplify the regulatory framework. It is too complex.”

James Astor, Managing Director at Agrivert Biogas, said:

“Recent Government actions mean that private equity and banks see Government renewable policy as a “risk” that has to be priced.”

David Williams, Chief Executive at Eco2, stresses that this uncertainty goes back further than the past six months:

“Investor confidence has deteriorated with the many changes in legislation seen in the UK over the last two years.”

Tim Jackson, Geothermal Development Manager at Sinclair Knight Merz, said:

“The UK is falling behind other countries in Europe and Africa in terms of attractiveness for investment in new renewable generating technologies.”

Energy Bill & Electricity Market Reform

The REA is not surprised that the electricity sector recorded the highest levels of ‘very poor’ confidence. The REA is currently urging Government to solve the critical route-to-market issue for independent generators, and will debate this issue at an open meeting on 27th March [5]. Independent generators are expected to deliver between a third and one half of necessary UK investment in the power sector to 2020. There is widespread concern that, as currently conceived, Contracts for Difference are not investable for independent generators. Ministers have committed to securing a solution and are expected to report back in June/July.

Andrew MacLellan, Director of ENER-G, said:

“Lack of regulatory and incentive stability, with a three to five year outlook, is proving a major obstacle to investment in the sector. Last year it was the RO review, this year it is EMR.”

Steven Edrich, Head of Strategy at 2OC, said:

“Continuing uncertainty over EMR and how the RO will be left to work beyond 2017 are crippling industry’s ability to look ahead and making it very difficult for banks to approve funding on projects now.”

Sector-specific concerns

There is more confidence in the small scale Feed-in Tariff than the Renewables Obligation or Renewable Heat Incentive. Overall, 65% of respondents in renewable heat and electricity had poor or very poor confidence in their sector’s regulatory framework.
