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.”

The UK feed-in-tariff announcement has generated a lot of interest in solar energy for homeowners. But what of the interest for organisations such as farms, businesses or local communities?

Some in the press have criticised the government’s proposed feed in tariff plans because they do not offer specific incentives to businesses as well as private individuals.

I would argue that the feed in tariff as it stands applies equally well to enterprises as it does homeowners. Businesses are often able to think longer term about investments. The incentives for installations above 50kW are still attractive for commercial roofspaces, especially if businesses use the electricity they generate for themselves, meaning that installing solar would be a prudent investment to have on a balance sheet. That is not to mention the kudos that comes with being a net exporter of green electricity.

In Germany the commercial rooftop segment of the market is the largest by volume, and with a feed in tariff pricing that now looks rather similar to the UK’s. We may therefore expect that companies start to explore using their roof space for PV. In fact if they haven’t thought of it yet, someone else will soon be approaching them with an offer.

That’s not to say the governments plans are flawless however. The UK is still pitifully behind the rest of Europe when it comes to renewable energy generation and particularly microgeneration.

Still lurking in government policy the ridiculously low target of 2 percent of energy coming from microgeneration by 2020. This is incomprehensible given that Germany is already at 4 percent from solar and other countries like Denmark with biomass gain nearly 40 percent from microgen. Surely this target must be revised!

Speaking as a professional in the global solar industry, the new UK feed in tariff has put us on the radar (a bit). Rather than smirking when I mention the potential for solar in the UK, my colleagues are now starting to take some interest…

With the UK government’s announcement of the introduction of the Clean Energy Cash Back system, essentially a feed-in tariff designed to attract investment in the British renewable industry, controversy has raged with solar industry insiders believing tariff rates to be too low.

It therefore comes as no surprise that the Federation of Master Builders (FMB) has also announced that they believe the tariff rate which has been set (5p/unit with a subsidy of 36.5p for units of energy generated by small scale solar and wind installations) will be too low to make the UK market competitive and have suggested a rate increase of 10p.

Speaking under the banner of the widely publicised ‘We support solar’ campaign the FMB’s announcement comes in the light of a number of criticisms aimed recently at the Department of Energy and Climate Change (DECC) legislation to be introduced in the April of next year. The FMB is being given the full backing of the National Federation of Roofing Contractors (NFRC), and Electrical Contractors’ Association (ECA) with around 16,000 building firms adding their weight to the ‘We support solar’ demands.

Feed-in tariffs are designed to offer premium, guaranteed rates to small scale producers for renewable energy which is fed in to the national grid and bought by the utility companies. In markets where they have been introduced elsewhere they have proved successful at attracting investment in new solar markets. In Germany and Spain, solar sectors have experienced booms thanks to the attractiveness of solar stocks in those countries with high returns on investment made possible by the feed-in tariff mechanism.

It is certainly considered that while the UK does not enjoy Iberian sunshine levels a strong tariff would enable the sector in the UK to take off and of course attempt to catch up with other mature markets. Some critics have argued that a strong anti-solar lobby in Westminster led by the utility companies has influenced the government’s decision to go forward with legislation which is generally accepted to be insufficient. With this in mind Liberal Democrat MP Simon Hughes stated,

“The proposed “cash back” payments are designed to dampen solar PV demand over the next three years rather than to encourage it. This mindset needs to change. Solar power can play a significant role in the “greening” of our towns and cities, while providing tens of thousands of new construction sector jobs.”

Indeed, with support among certain power brokers and pro-solar lobbies acting to add 10p to the current tariff it may well be possible to tweak the legislation, making it workable in the long term. If not, the ‘We support solar’ campaign may fail to see the fledgling UK PV sector take off.

Labour MP and advisor to the Department of Energy and Climate Change (DECC) Alan Simpson has warned of the presence of an cartel acting against the interests of renewable energy in the UK. At an event organised by Solar Century to promote the government’s proposal of a feed-in tariff system, Simpson announced that there is currently a lobby opposing the renewable campaign headed by the big utility companies keen to protect their own commercial interests at the expense of the development of green energy in the UK.

With the government’s announcement regarding the introduction of the Clean Energy Cash Back system (essentially a feed-in tariff system) in April 2010 much debate has raged regarding the tariff rate which will be required in order to optimise investment in the fledgling UK renewable energy industry.

The feed-in tariff works on the principle that small, renewable energy producers are guaranteed a fixed, premium rate for all units of energy they feed back into the national grid. The renewable energy units are purchased by the utility companies, something which they are obliged to do by the tariff legislation. In actual fact, the government has set a rate of 5p/unit with a subsidy of 36.5p for units of energy generated by small scale solar and wind installations, something which Simpson has controversially asserted will not be sufficient to spark the must needed investment in the industry.

Simpson claims that with the current rate set at 5p, the ROI for solar investors will only be around 5-7 per cent, yields which would possibly not be generous enough to turn the heads of investors who would potentially be attracted by more generous tariff rates elsewhere in the world. With a tariff rate of 10p, Simpson believes that returns could be a more healthy 10 per cent, rendering the UK as a highly competitive market in the world for attracting renewable investment in the long term.

For the UK to finally become one of the major players in the world of solar drastic changes will need to occur within the coming years to catch up with established markets such as Spain and Germany who are currently generating 2,511 MW and 1,500 MW of renewable energy annually respectively compared to the UK’s peak 6MW. Simpson certainly believes that this shortfall can only be remedied with the introduction of comprehensive tariff systems. Speaking at the Solar Century event, Simpson announced,

“Current energy policy in the UK is dominated by the vested interests of “Big Power”. The national grid is monumentally inefficient as an energy system. It was a half-decent idea for the middle of the last century, but 70%-80% of energy put into the grid disappears before you or I even switch the light on. We need not an energy, but a power revolution that takes control from the centre and literally puts power back into the hands of the people”.

Those within the industry back the words of Alan Simpson and are well aware that the future of the UK renewable energy industry is completely reliant on a strong tariff rate. Come April, it will be there to be seen if the government’s rhetoric on tackling climate change can be matched by a determination to take on the big utility companies and drive through a system which will see the UK become a leading light in the green energy revolution.
