PIU: £100m for Renewables

In November the Performance and Innovation Unit published its recommendations on how to allocate the extra £100m that Tony Blair had promised for renewables last March. It called for:

- £25m for offshore wind

- £15m to help farmers and foresters establish energy crops

- £10m dedicated to innovative PV schemes

- £10m for PV and other technologies that can be utilised directly on homes, businesses and community buildings.

- £10m for fundamental research on the next generation of renewable energy technologies.

The PIU also called for: £5m for demonstration and testing of wave and tidal technologies; £4m for advanced metering and control technologies so that electricity grids can best harvest PV and other small-scale technologies; and a further £18m for the development and demonstration of advanced energy crop technologies for clean and efficient production of heat and electricity.

Backing the proposals, the Prime Minister said: "I am determined that we will reach our target of meeting 10% of our electricity requirements from renewable sources by 2010. This money will help us reach that target by encouraging the delivery of capacity on the ground. And I also welcome the funding for solar, wave and tidal technologies, and on blue skies research, which have such a vital role to play in helping us meet our medium and long term renewable energy needs".

According to the Cabinet Office, the PIU team has made detailed spending recommendations in order to maximise the gains from the extra money and where possible, funds will be injected into existing schemes to minimise additional complexity and bureaucracy, getting money directly and quickly to businesses and the community’.

On the £25m for offshore wind, it noted that the UK has huge offshore resources and wind energy is now poised for the move offshore. But the 'first movers' will need carefully targeted support to take them through the challenging early stages’.

On the £20m allocated for solar, and other technologies that can be utilised directly on homes and businesses’, it noted that £10 m will go to increased support for innovative PV installations and £10m to support solar, biomass heat and other renewable community projects’. The £15.5m to help farmers and foresters establish energy crops, will it says help develop heat and electricity markets and build up the necessary infrastructure for energy crops and forest wood fuel’. In parallel, there was £18m for development and demonstration of advanced energy crop technologies for the production of heat and electricity, e.g. CHP.

The £5m for demonstration and testing of wave and tidal technologies, was for an area where UK research leads the world, but where more experience is needed of full-scale projects in the open seas’. And looking further ahead, there was ‘£10 million for fundamental research on the next generation of renewable technologies, and for associated technologies such as energy storage’, plus £4 million for advanced metering and control technologies so that electricity grids can best harvest PV and other small-scale technologies’.

Finally there would be £2.5 million to provide information and support to planners and local decision-makers, and land use planning purposes generally’.

Not bad, as far as it goes. We summarise some of the key recommendations in the next four sub sections.

PIU Report

In its report, ‘Building for the Future of the Environment’, the PIU say that its aim was to provide an extra boost to renewables by helping to get offshore wind off the ground; developing heat and electricity markets for energy crops, demonstrating new technologies, and building up the necessary infrastructure; doubling the support available under the Government’s intended major demonstration of innovative solar photovoltaics; encouraging and promoting smaller scale domestic/community based renewable energy; and facilitating the connection of renewable sources to the UK’s electricity network’.

In addition it would take forward the development of wave and tidal stream technologies, and almost double the budget for fundamental research that will develop the next generation of renewables’.

Not a bad set of aims, with the support for renewable heat technologies being particularly welcome. So is the £5m for wave and tidal current technology- even if the terms of the support are rather contorted, as if the PIU is nervous about making too strong a commitment to this novel area.

The £10m committed to community projects is also a bit token - the focus is on small scale grant aided community projects, rather than on local co-op or other community enterprises, which might then support themselves. But it’s a start.

The £10m Blue Skies research programme is to be welcomed - as the PIU say, the money will be spent on fundamental research into a range of technologies which could include innovative approaches to solar PV, wave and tidal power, storage and the capture, storage and transmission of hydrogen’.

The PIU add Criteria for allocation of this funding will be drawn up by DTI in collaboration with the EPSRC and other Research Councils, but will recognise the uncertainties associated with "blue skies" research, and not be overly prescriptive. At the same time, research programmes will be co-ordinated as closely as possible to maximise potential synergies and to avoid duplication of effort’.

The next three sub sections summarise the PIU’s analysis and recommendations.

PIU: OXERA Scenarios

In order to provide a context for deciding about the allocations, the PIU commissioned OXERA to carry out an analysis of the likely entry of renewable generation between 2002 and 2020 in response to the Renewables Obligations. OXERA based their work on a model designed to show the potential market penetration of a number of technologies following the introduction of ROCs- the Renewable Obligation Certificates given to companies who meet the obligation and traded between those who had excess and those who could not meet the Obligation.

The OXERA work suggests that achieving the 10% 2010 target is, in principle, possible without any additional financial support, although, the PIU notes, there could be problems, most obviously due to NETA, but also due to planning delays. The PIU comments that the build rate for all renewable technologies- especially onshore and offshore wind, which are likely to be the main contributors to 2010- will need to increase by about two orders of magnitude’. However, although additional capital grants will help to deliver an improvement’, the PIU fears that unless further action is taken to make renewable energy schemes more acceptable to local communities, and to facilitate the process of obtaining planning permission (in particular for onshore wind) and connection to distribution networks, the required build-rates are unlikely to be achieved’.

In particular the PIU note that ‘The larger wind farms (above 1MW) awarded contracts under NFFO have encountered the most severe problems in gaining planning permission and only 41% of projects that have applied for planning permission under the later rounds of NFFO (orders 3 - 5) have been successful. Biomass projects have also encountered a number of difficulties gaining planning permission’.

It mentions the various revisions underway to the planning system, but notes that, in the end it comes down to public attitudes. Public opinion surveys show that the majority of the UK’s population support the development of renewable energy. Moreover, there is considerable evidence that local populations tend to become more favourably disposed towards local renewable energy power plants once they are built. This, however, does not translate into a "cultural" perception that Britain is supportive of renewables, as would be perceived in (for example) Denmark, Spain or Germany. And this support for renewables at a very generalised level has not prevented opposition to individual projects at the local level.’

The PIU also sees some potential economic problems ahead, if for example, the price of ROCs turn out to be lower than expected, due perhaps to the import of cheap green power through the inter-connector, or through links being made to wider emissions trading schemes or to a European-wide ROC trading scheme.

Looking further ahead, to 2020, they say that the value of ROCs could become even more of a problem unless the overall RO capacity target was expanded. Fortunately it thinks that a target of 20% by 2020 is credible. In particular, in addition to a major continuing contribution from offshore wind, it suggests that energy crops could make a contribution over the short to medium term- up to 2600MW by 2020, in one scenario. However, it adds for this to occur, considerable cost reductions will need to have been achieved and the necessary planting schemes put in place over the period to 2010. If these requirements are to be delivered, Government subsidy and facilitation of contracts between growers and energy companies is likely to be required’.

The PIU also point out that penetration levels of much above 20% from intermittent generation sources (i.e. wind and solar) and to a lesser degree hydro (which has a higher level of prediction capability) could start to create additional issues for management of the overall electricity system- initially additional costs. Though of limited concern at present, this suggests that in the longer term, effort should be devoted to technologies that maximise the value of intermittent sources- in particular advanced network (and demand) management systems, and energy storage’.

It says that these issues will be addressed in more detail in the PIU review of energy policy.

Looking to the longer-term, to 2050, the PIU note that OXERA’s quantitative scenario methodology is no longer viable and instead OXERA made use of a ‘learning curves’ approach coupled with general engineering assessments, as developed by the PIU and by Imperial College. Within this context, it says that ‘the hierarchy of technologies is wave and tidal stream, followed by offshore wind, then energy crops and PV’.

Essentially what they are saying is that, as far as the potential for learning and technological development is concerned wave/tidal and PV offer the greatest opportunities. As a relatively mature technology, onshore wind offers the lowest opportunities for further learning. This assessment must however be modified by an judgement of the potential for the technology to be used in the UK. This, the PIU says, tends to work against PV, and in favour of wave/tidal and offshore wind, where the UK’s potential resource is huge. In addition note has to be taken of the likelihood of eventual commercial viability. The risk of economic failure is seen as greatest for wave/tidal, which is the least developed of the technologies. However, the PIU conclude the strong possibilities for learning and for use in the UK mean that wave and tidal remains at the top of the OXERA hierarchy’.

Although the OXERA analysis does not provide assessments of the export potential of the various technologies, the PIU say that what it does suggest is that, even if the total UK market for a particular renewable energy source appears to be limited, there may be merit in developing a UK-based industry if world markets are likely to be large. The technology for which this argument is most relevant would appear to be PV’.

PIU: Rationale for Funding Plan

Offshore Wind

Offshore wind is seen as a key technology, but the PIU notes that the economics are still subject to many uncertainties. ‘Although it could become commercially viable by 2010 under the RO, this will be dependent on projects getting off the ground early in the decade’ .

In particular, the PIU feel that winning investor confidence will be difficult due to uncertainties relating to, for example, the NETA imbalance charges, the value of ROCs; and planning process and public perceptions. This, the PIU says, means there is a strong case for additional capital grant support. If one assumes that the 18 developments (of a maximum 30 turbines) which pre-qualified in the Crown Estates licensing round use the currently available 2MW turbines, this would represent 1080MW of capacity. Existing funding should be able to support at least 300MW (at the maximum rate of approximately 0.6p/kW). Up to an additional £25m is made available to fund offshore wind installations. This should cover at least another 150MW, meaning that approaching half of the licensed capacity (or about 0.5% of electricity (or 5% of the Governments target) could be guaranteed early progress’.

The PIU feel that support for a minimum of 450MW will be enough to reduce the risk element of developing offshore wind, and to generate sufficient early momentum for offshore wind to play its full part in meeting the 2010 target’. But this should be ‘kept under review’.

Energy Crops

The other main component in the mix is energy crops, which the PIU say could also become a significant renewable resource over the next few years, although, as noted earlier, it also sees major barriers related to the establishment of infrastructure and to the contractual relationships linking the growers to the energy providers. On the generation side, the PIU note that some existing funding is available for electricity generation from energy crops through the New Opportunities Fund, which the additional funding from the £100M are designed to complement.

It goes on ‘One area for funding will be near-commercial electricity schemes, particularly those classified as CHP. Up to approximately £10m will be allocated to support near commercial energy crop and forestry woodfuel schemes. A further criterion is that preference should be given to schemes which can be classified as good-quality Combined Heat and Power (CHP). This should allow the development of around 10 MW of steam combustion plant or (0.2% of the 10% target). It is expected that these schemes will be a range of sizes, and no prescription should be given for this aspect. This support for the nearer term technologies will help to establish the growing of energy crops in the UK’.

Although it says that good-quality CHP has the benefit of much greater efficiency (70% or more) than electricity generators using energy crops (30-35%), the PIU recognises that there may be times when CHP is inappropriate (e.g. when no use for a heat-load can be found), and projects in these circumstances should not be ineligible’.

This funding will be administered by DTI, with input from DEFRA and the devolved administrations. The PIU suggest that one possibility for maximising the value of the funding would be to make the establishment of contractual relationships with growers a pre-requisite for receiving support’.

Clearly, the PIU see the development of infrastructure that links growers and energy providers as vital. Although it recognises that DEFRA is making available funding for planting grants, to sit alongside other funding for energy crop generators,‘a potential gap relates to the infrastructure required to harvest, store and supply the energy crops once they have been grown’. In order to meet this gap,‘up to £3.5m will be made available specifically to help fund market or physical (harvesting, storage and supply) infrastructure. This fund may be available for producer groups, in particular those non-SRC schemes not covered by the existing DEFRA Energy Crops Scheme. The funding should be administered by DEFRA directly alongside this scheme, in order to ensure effective allocation. However, the amount available for infrastructure should be ring-fenced’.

Finally, the PIU note that another aspect to energy crops not currently funded is the use of energy crops for industrial heat applications. In the same way as early introduction of energy crop CHP could help establish the energy crops industry in the UK, industrial heat from energy crops would seem to provide the potential for an easy win. This is already supported in part through £3m from the NOF but receives no other direct support, and is not covered by the Renewables Obligation. On this basis, and in view of the wider benefits, up to £2m will be made available for industrial heat from energy crops, to be administered directly alongside the existing NOF money.’

This funding complements the community and household fund (see below), and could, the PIU suggest, support a further 10 MW of heat-equivalent at a maximum 50% subsidy, in units of 500kW or more. This is only equivalent to less than 1% of the 10% target but is intended to pave the way for a much more substantial contribution between 2010 and 2020’.

Community Projects

The PIU recognises that it is vital to find ways to try to overcome the barriers imposed by local attitudes, and planning processes. It argues that there is some concern that the majority of renewable energy projects are seen as relatively large-scale and/or promoted by remote large companies and somewhat inaccessible to households and individuals’ and claims that initiatives on the planning front will not help get renewable energy off the ground unless the public extends its general support for renewable energy to support for renewable energy in local situations. This makes community engagement crucial, so that more people are either individually involved in renewable energy schemes or able to see them’.

It goes on, One means of overcoming these concerns will be to make funding available specifically for renewable energy schemes that engage local communities or individual households’. It adds, somewhat surprisingly, that ‘we have made good progress in developing community schemes in the UK and currently there is a small amount of funding available through both the Countryside Agency’s Community Renewables Scheme and the New Opportunities Fund Green Spaces and Sustainable Communities Scheme’ .

Well maybe, but not yet much to show for it compared say to Denmark. Certainly, as the PIU go on, ‘more funding will have a beneficial impact in this area’. To that end up to £10m will therefore be allocated to a programme spread over three years, for which bids are invited on behalf of schemes with a strong local community or household interest. The scheme will be administered by DTI, working closely with the devolved administrations’.

Again, perhaps a little tendatiously, given the low level of deployment so far, it adds Community schemes have proved very successful in allowing local residents to directly gain from local developments and feel they have some ownership of them. They have an important role in familiarising individuals with renewable energy technologies and it is expected that these schemes will then allow a number of larger schemes an easier path to gaining planning permission’. Lets hope AAT (see Groups) will benefit. They just had their bid to the DTI for funding turned down!

The PIU conclude no restrictions will be placed on the types of technology employed, but eligibility would be restricted to renewables deployed at the level of households, or buildings/land owned by non-profit making organisations. Care would need to be taken to ensure that this scheme does not duplicate existing programmes’.

An example might be a "solar street", involving the fitting of solar panels to the roof of every house in a street; incorporating solar water heating into the design of new civic buildings; installing a wind turbine to provide electricity to a school or hospital; biomass heat projects for schools or farms.

On the planning side, it is recommended that up to £2.5m be allocated to the administration of a series of regional road-shows, to which regional and local authorities would be invited, alongside those expecting to make planning applications. Other facilitation-type-schemes could also seek funding through this fund. The purpose of these seminars would be to share information and best practice with respect to the treatment of renewable energy schemes’ The PIU say the DTI should administer this scheme.

Better network connection was also seen as vital, to aid local schemes. The PIU say a useful approach will be to demonstrate the new technologies that can help make renewables more attractive’. Up to £4m will therefore be placed into a fund, for which bids will be invited from suppliers, brokers and Distribution Network Operators. The purpose of this fund will be to facilitate the demonstration of new control, storage and metering technologies, with a view towards active management of distribution networks’.

PIU: Longer term options

The PIU argue that even as we take action to deploy renewable technologies and deliver on our commitments, it is essential that we prepare for the longer-term by bringing on technologies currently some way from commercial viability, and by undertaking research into new technologies’.

It notes that ‘many of these issues will be picked up in other work currently under way, such as the PIU review of energy policy and the DTI-led review of energy R&D. However, it is possible to identify now some areas where support will be important in developing renewable energy sources for the longer-term’.

It goes on There would seem to be three key technologies that are currently some way from commercial viability, even under the RO, yet have the potential to play a very significant role in the long-term in the UK or elsewhere. These are new energy crop technologies such as gasification and pyrolysis; photovoltaics (PV); and wave or tidal power.’

New Energy Crops

The PIU say that, although energy crop technologies are probably nearest to commercial viability in the UK, there is very limited experience of these technologies in practical application in the UK or elsewhere. Without this practical application, it is difficult to see how costs will fall over time. With other mechanisms in place to set up the supporting infrastructure and contractual relationships for the energy crops industry, up to £18m will be made available to prepare the UK for the next stage of energy crop technologies. This fund will be administered by DTI, working closely with DEFRA and the devolved administrations and taking account of the administration of the NOF money already available for energy crop technologies. It will also be applied in close conjunction with any EU-wide funding programmes, in order to extract maximum benefit’.

Wave and Tidal Power

Wave and tidal power, the PIU say,‘offer perhaps the greatest long-term scope for the UK. The UK has a large potential wave and tidal resource and a long history of pioneering R&D in these areas’.

However The technology is still in its infancy, with many competing designs, and considerable uncertainty about whether and when commercially viable technologies will be delivered. This presents both a threat and an opportunity. Without support, the technologies may not develop at all, and their long-term potential may not be realised. But because they are little developed, the UK has an opportunity to exploit a world-leading expertise at relatively low cost’.

It goes on The UK is still one of the world leaders in marine technology. Several new companies have spun out of UK universities and some have been successful in attracting commercial backing. However many analysts suggest that, with more generous support available in other countries, the UK may already be losing place in the marine technology industry. With more proactive political support and considerably more resources (at present) going into wave technology in Denmark, the parallel with the early development of wind power is not difficult to draw’.

It adds Some of the more promising technologies are now moving beyond the laboratory and very early prototype phases, and an increasing number of demonstration devices are going into the sea in several countries. A few of these have secured power purchase agreements, including support through the SRO in the UK, and are effectively in pre-commercial demonstration. However there is a clear need for further substantive field trials’.

The PIU note that the DTI "Technology Route-maps" for both wave and tidal technologies focus on support for long term trials of prototypes, alongside ongoing R&D into less advanced devices. And that the DTI provide for up to 10 years of prototype field-testing. But, the PIU say, should any of the technologies prove reliable and viable they would be able to move into what might be termed the ‘early pre-commercial phase’ - fully operational grid connected projects - much sooner.

It is not reasonable to expect such schemes to be commercially viable under the RO, and additional support is necessary to enable such schemes to be deployed on a modest scale. Up to £5 million will be made available for grid-connected early pre-commercial wave and tidal stream projects. The intention is to create a small niche market that would bridge a potential "valley of death" for marine renewables’.

The PIU say that this money should be administered alongside the existing DTI programme. A competition for funds, timed to provide a clear next step for those technologies emerging from the DTI field trials (or elsewhere), will be the best way to facilitate steady progression in wave technology. The competition will run in 2 to 3 years time, but should be announced as soon as it is practicable, to provide guidance and a competitive incentive for the emerging industry. There may also be a case for using some of the budget to provide for accompanying measures- such as contributing to the marine test station mooted by the industry’.

Finally it says It is important that this support is viewed only as a step on the road to commercialisation. The success of wave and tidal technologies should be reviewed again towards the end of this funding programme, with a view to additional support in future’.

Solar PV

The PIU sees PV as having considerable scope- in the UK and abroad’ so that additional support is justified.‘Solar PV technology in buildings is a long way from commercial viability in the UK. However, the costs of PV have fallen substantially over the last 25 years, and are widely expected to continue to do so as global markets expand. PIU analysis using ‘learning curves’ and market growth data reinforces the view that PV could become an important and cost effective UK option for decentralised power generation in the long term, probably around 2020. Some niche markets could emerge much sooner, such as the use of PV as a prestigious and "green" building cladding material for companies wishing to demonstrate their environmental credentials. PV is already competitive in niche markets in sunnier latitudes, in particular off-grid applications, and large important global markets will emerge in the near future’.

In the "Opportunity for All" White Paper published in Feb 2001, the Government announced a major PV demonstration programme with industry and others, in line with those in Japan and Germany (70,000 and 100,000 roofs respectively). However, the PIU note, even a 100,000 roofs programme would not make a significant contribution to the 10% renewables target by 2010 or to the CO2 reduction targets. The rationale for such a support programme would be to encourage a strong industry to develop in the UK over the medium-term, which would be competitive in the potentially large export markets. The medium-long-term role of PV alongside other renewable technologies will be considered fully in the review of energy policy. The appropriate role of any long-term target in encouraging the promotion of PV will also be considered. Other issues for consideration include the role of PV as a niche urban technology alongside micro-CHP and micro wind turbines, and its role alongside these technologies in breaking down barriers to domestic generation’.

The PIU add A key UK strength is in architecture and building design. Innovative PV applications in buildings have been pioneered by UK architects and building engineering companies. We therefore propose that the UK PV programme should focus on these strengths. The UK also has strengths in the development of new PV materials and concepts, and these will be eligible for additional support for ‘blue skies’ research’, (see below).

To this end, up to £10m will be made available to add to the DTI’s existing £10m PV demonstration programme. The detailed criteria for DTI’s existing scheme are currently being finalised and a key criteria for this scheme is likely to be that the scheme will run as a competition into which bids would be invited for innovative applications of PV technologies. This would be open to households, companies, builders and architects, and would focus on new and exciting applications of existing PV technologies’.

Blue Skies Research

Finally there’s "Blue skies" research, which the PIU see as preparing us for the longer-term, opening up new options for renewables. Over a 50 year time period, it is highly likely that new technologies not currently anticipated could come to play a significant role. New renewable energy devices may emerge, but in addition, facilitating technologies, such as inter-seasonal storage or compact energy storage for vehicles, could enhance the prospects for renewable energy, especially intermittent renewables. As an important step in expanding the knowledge base on which we depend to realise the potential of renewable energy, up to an extra £10m will be given to the Research Councils over the next three years. This will almost double current levels of spending.’ And not before time!
