With the government’s consultation on proposed cuts to the feed-in tariff drawing to a close, solar industry members are anxious to see how drastic changes to the tariff will be. Many involved within the UK solar industry are fearful that reductions in the solar tariff of up to 70 per cent for pv energy generators over 50MW. Whatever the nature of changes to the solar feed-in tariff mechanism, it is more than likely that the worst affected will be large scale installations such as the large scale solar farm sites which were looking to tap into tariff revenue.

The solar feed-in tariff works by guaranteeing fixed, premium rates for units of energy both used and fed-back into the grid by small scale pv generators. The government has made it clear that it would like to see households benefitting from this scheme rather that large scale projects. Indeed, smaller scale solar businesses have argued that this change is necessary to ensure that funding goes to those areas which most need capital. While this may be the case, other solar businesses have stressed vehemently that strong tariff support for larger scale projects is essential as it will be those projects whch drive the industry, bring costs down and of course put impetus on technological innovation.

Whatever the differentiation between small and large scale projects made by the Department of Energy and Climate Change (DECC), the essential fact is that reducing the feed-in tariff will harm the UK solar industry by significantly reducing investor confidence in solar projects. All previous research and experience from abroad has shown that a strong tariff system is needed in order to provide investors in solar pv with long term returns on investment protected by government legislation; where these tariffs fall by the wayside, investor confidence in ROI tends to as well. Many within the industry have therefore been lobbying the government incessently, trying to convince the DECC of the need to rethink proposed cuts. Leonnie Greene of the Renewable Energy Association stated that,

“Our view is that the overall ambition is much too low and the government clearly does not understand the strategic importance of solar. We are going back to a scenario where a few wealthy green home owners can install solar, when we want to be widening access to solar, particularly through community scale projects.”

Engineers are calling on the Government to increase the remit of the Green Investment Bank. The Coalition has signalled their intent to direct the Bank’s fund towards investment in low carbon technology. But, Europe’s largest professional group of engineers, the Institution of Engineering and Technology (IET), is arguing that the Bank should also support energy efficiency innovations in the manufacturing sector.

The investment mandate for the Bank is to deliver the Government’s aims on economic growth, facilitate the transition to a green economy and support the UK’s industrial transformation. Much of the focus to date has been on investment in the manufacture of low carbon goods and the rollout of green infrastructure.

Dr Tony Whitehead, Director of Policy at the IET said: “Energy conservation and efficiency should be amongst the first priorities of a sustainable energy policy.

“Energy is set to become increasingly expensive in the future, and to survive in the global market, UK firms will not only need to produce new products, but to produce them at competitive prices. This means driving costs down wherever possible.

“The manufacture of low carbon technology is often seen as a panacea to meet the UK’s carbon reduction requirements whilst at the same time creating a renaissance in UK manufacturing. Yet the manufacture of low carbon goods is not in itself automatically green. A green industrial revolution should first focus on greening manufacturing processes to reduce energy and resource use.

“For the UK to achieve its targets on carbon emissions there needs to be extra support for green manufacturing processes. Energy conservation and efficiency in the manufacturing sector should be a priority for the Department of Business, Innovation and Skills and more widely across government.

“In addition, access to the Green Investment Bank by SMEs will be paramount. SMEs are able to develop and commercialise products rapidly in niche areas. By its very nature, green technology and processes will require innovative solutions; an area where SMEs can develop a competitive advantage for UK plc. SMEs should have priority access to the Green Investment Bank to spur green growth and technology.”
