UK power "will be 85% more expensive" without energy storage

Without large-scale energy storage, the UK government won't meet its renewable energy ambitions, says Edwin Koot, CEO of SolarPlaza.

The price of power in the UK will be 85% more expensive than in Germany (Europe’s biggest energy market) by May 2015, according to data compiled by Bloomberg.

U.K. power will cost £53.06 per megawatt-hour in May 2015, compared with €33.30 in Germany, according to fair value calculations on Bloomberg as of 8:40 a.m. in London.

They attribute the stark difference to Germany’s advanced renewable energy programme, which accounts for 30% of power generation, compared to the UK’s, currently standing at 11.3%.

The 2015 picture compares with an average premium of 17% over the past five years and 80% today, according to data from Marex Spectron Group Ltd., a London broker.

While Germany is seeking to consolidate its status as Europe’s biggest producer of wind and solar power by boosting its share of renewables-sourced energy to 35% in 2015 from 22% last year, the UK is targeting 15% from 11% over the same period, and is predicted to fail to meet the 20% 2020 EU-wide target.

Statkraft AS is closing money-losing gas-fed plants in Germany, while Macquarie Group Ltd. (MQG) and Vitol SA are buying British power stations, betting on gains of as much as 19% in U.K. prices by 2016, according to Societe Generale SA.

“The U.K. has built significantly less renewables to date,” Ilesh Patel, a partner at Baringa Partners LLP, a consulting firm that counts EON SE and Electricite de France SA (EDF) among its clients, said. “Germany has been on a fast-track wind and solar plan.”

Many critics of investment in renewable energy in the UK point to the fact that Germany, which is investing heavily in renewable technologies in its push to abandon its reliance upon nuclear power, currently has higher power prices than the UK.

However, Ed Davey, Energy Secretary, has consistently said that Britain's programme of supporting renewable energy will eventually lead to lower prices.

The key to this development may be investment in energy storage.

Germany is offering incentives worth €25 million to help subsidise the installation of batteries alongside solar PV systems to store electricity for use at night time. Simon Daniel, Founder of energy storage company Moixa Technology, says this "is helping our European neighbour to realise the full potential of renewable technology".

The UK Minister for Energy and Climate Change, Gregory Barker, is to deliver the keynote speech during the upcoming Solar Future UK ’13 event on July 16 at which he is expected to enlarge on his announcement, made at the recent Intersolar conference, that Britain hopes to deploy 20 GW of PV by 2020, in relation to how this affects Britain's energy storage capacity.

At the Intersolar event, Barker said that "the UK Government is totally committed to building a world-class renewables industry” and quoted Prime Minister David Cameron as saying that he wants to "make Britain a global showcase for green innovation and energy efficiency".

At the following day's Energy Storage UK '13 conference, leading industry spokespeople and cleantech businesses from the UK’s energy storage sector will discuss how the latest energy storage systems (ESS) will advance the integration of renewable energy, such as solar PV and wind.

"Deployment potential of solar PV is greater than the UK’s grid storage capacity," comments the CEO of SolarPlaza, Edwin Koot. "Without large-scale energy storage solutions, the UK Government’s ambition to reach this figure presents a significant challenge for National Grid, which has already warned that building more than 10GW will make it difficult to manage the network in its current form."

Director of the Electricity Storage Network, Anthony Price, is warning that "if the Government does not support the use of storage as part of the solution to meet our power shortfall, we will lose this opportunity, and live to regret it.

"What is low cost now will take us down power’s one-way street. It will be difficult and costly to reverse. Our plans for the Smart Grid show we need storage and we must seize this opportunity now.”

The intermittency of solar PV and wind requires utilities to maintain additional spinning reserve from polluting power stations to pick up loads, or, in the future, use demand-side reduction techniques in the capacity market, in the event of peak demand spikes.

If the potential of intermittent renewables is to be fully realised, the National Grid will require fast-acting energy storage systems that can dispatch power and respond quickly to network imbalances, says Price.

That the power industry and policy makers are not paying sufficient attention to the challenges arising from integrating intermittent power generation into the system was felt by 60% of attendees polled at the recent POWER-GEN Europe and its co-located conference, Renewable Energy World Europe, between 4-6 June at the Messe Wien, Vienna.

Davey buys £20m for onshore wind in exchange for £500m for gas

Subsidies for onshore wind farms will be reduced by 10%, not the 25% demanded by the Treasury, says Energy Secretary Ed Davey, but at a long-term cost to carbon emissions.

To win this agreement, the Department has had to concede that gas generation will continue "to play an important part in the energy mix well into and beyond 2030, while meeting our carbon budgets".

This "important part" is ensured with a grant of £500 million for gas field exploration. To put this in context, the dispute between the Treasury and DECC centred over a difference of around just £20 million in support for 1GW of onshore wind.

The effect on greenhouse gas emissions after 2030 is likely to be alarming. David Nussbaum, chief executive of WWF-UK, sent a letter to David Cameron yesterday, complaining of "a clear bias on the part of Mr Osborne towards investment in new gas-fired power stations" which would imperil the UK's climate targets and could raise bills for consumers.

“The proposal that emissions from gas plants built before 2015 will effectively never have to limit their emissions jeopardises our ability to meet UK carbon targets," he said. “The announcement on this, which was slipped out late on a Friday and which had the Chancellor’s fingerprints all over it, is another example of the Treasury’s malign influence on energy policy."

John Sauven, Greenpeace's executive director, also commented that: “The Treasury is fighting tooth and nail to oppose a 2030 decarbonisation target or support for future renewables targets. Mr Osborne has rebranded himself Mr Polluting Gas. It's up to Nick Clegg to stick what's left of Lib Dem principles back into this process."

£25 billion investment

However, marine energy developers will celebrate a 250% increase in their support from 2 ROCs (renewable obligation certificates) to 5 ROCs per MWh, subject to a 30MW limit per generating station.

"The case for investment in renewable energy is so strong and that is why, across government, we are backing it," said Energy Secretary Mr. Davey, making the announcement.

He said that representatives of industry and business support the subsidy cut of 10%, but not of 25%. “And that will bring forward investment between £20 and £25 billion between 2013 and 2017, and create hundreds of thousands of jobs," he promised.

"No one would want to over-subsidise an industry," he said.

He tried to reassure the wind industry by saying that there would not be a further change in the support levels or targets for carbon reductions in the autumn.

"The climate legislation says that if there has been a change in any of the generation costs for a renewable technology, whatever it is, we should have a review. So if it does change dramatically, then of course everyone agrees that we should have a review."

When pressed by James Naughtie on the Today programme this morning, Ed Davey said that meeting emission reduction targets depended on carbon capture and storage and nuclear power coming on stream by 2030, as well as major investment in renewables. He did not mention demand reduction.

"We don't have a target for the amount of energy to be generated from renewable sources at the moment," he said. Mr Davey said that there was cross-party agreement on the legally-binding targets to reduce carbon emissions. "What we're discussing is whether there should be an intermediate target for decarbonising the power sector. There is a debate to be had about that, around the Energy Bill," he said. That is expected in the Autumn.

The announcement of the results of the Banding Review consultation for the Renewables Obligation was delayed last week, following intervention from the Treasury, but was finally announced today.

The Department for Energy and Climate Change (DECC) quantified the impact on consumer bills between 2013 and 2015, as a reduction of £6 off household energy bills next year and £5 the year after.

By 2017, DECC hopes that this will deliver as much as 79 TWh of renewable electricity per annum in the UK, 11 TWh more than at present, which still not enough, just 74%, of the 108TWh of electricity needed to meet the UK’s 2020 renewable energy target.

The Renewables Obligation is the Government’s main mechanism for supporting large-scale renewables, and the review covers the final period of support, 2013-17 (2014-17 for offshore wind), before the scheme ends.

The announcement comes ahead of the Government's Global Investment Conference and series of 17 business summits taking place at the British Business Embassy at Lancaster House during the upcoming Games, which aim to secure further investment into the UK.

John Cridland, CBI Director-General, welcomed the announcement, saying it “will help to encourage investment into our energy sector, creating jobs and supporting growth". He also thought that "the Government is right that gas should play a crucial role in any future energy mix. We have argued that there is no need for a false choice between renewables, nuclear, gas, and carbon capture and storage. It’s clear from the evidence that we need a diverse supply.”

Support for onshore wind from 2013-17 will be reduced by 10% to 0.9 ROCs, guaranteed until at least 2014 but could change after then if there is a significant change in generation costs.

If there is evidence of significant reduction of generation costs in early 2013, then subsidies will again reduce in April 2014. The Government will also consider how local communities can have more of a say over, and receive greater economic benefit from, hosting onshore wind farms.

Biomass and solar

There will be a new band to support existing coal plant converting to sustainable biomass fuels. This will increase the amount of renewable energy produced at less cost to consumers.

The new enhanced co-firing band will be split into two new bands: mid-range at 0.6 ROCs/MWh, and high-range co-firing at 0.7 ROCs/MWh in 2013/14, rising to 0.9 ROCs/MWh from 2014/15.

This was welcomed by Dorothy Thompson, Chief Executive of Drax, the country's largest coal burning plant, which is in the process of conversion to be able to burn more and more biomass. She said that she is now “confident that we can transform Drax into a predominantly biomass fuelled generator".

Generators will need to burn at least 50% biomass in a unit to be eligible for support. Bioliquids are excluded from this.

There will be a consultation on lowering the support level for standard co-firing to 0.3 ROCs/MWh in 2013/14 and 2014/15, increasing to 0.5 ROCs/MWh from 2015/16.

Support for generation using 100% biomass is to be set at 1.5 ROCs/MWh, degressing to 1.4 ROCs/MWh for new accreditations and additional capacity added after 31 March 2016.

There will be no immediate reduction in support for large-scale solar, but, as with onshore wind, the level will be kept under review. Installations under 5 MW will only be eligible for feed-in tariff support.

New landfill gas generating capacity will not receive any support from 1 April 2013, but new generators using gas wholly from closed landfill sites will be eligible for support at 0.2 ROCs/MWh and electricity generated using new waste heat to power generating capacity will be eligible for 0.1 ROCs/MWh at both existing stations as well as new stations using gas from any landfill site.

The gas bill

In return for this extra 11 TW hours, DECC has given its commitment to a new dash for gas, provided that gas remains cheap.

It will have “a key role in ensuring that we have sufficient capacity both to meet everyday demand and complementing an increasing amount of relatively intermittent and inflexible generation", the DECC statement says. "We do not expect the role of gas to be restricted to providing back up to renewables, and in the longer term we see an important role for gas with CCS."

£500m of grants are being made available for large shallow water gas fields in the UK Continental Shelf, and more information on the Government's strategy will be set out in the Autumn.

How long is a long time?

Current government policy on energy technology is based on a curious mismatch of ideas about time

Ideas of 'a long time' vary according to context in the Low Carbon Kid's analysis of the government's Energy Market Outlook published two days ago.

There is enough uranium ore in the world to meet currently projected demand for up to 85 years, according to current estimates from the Euratom Supply Agency.

Renewable energy will, by contrast and by definition, last forever. Oh yes, and it's free.

Technologies which use renewable energies as a fuel source will therefore have application forever.

In other words, investing now in developing new renewable energy technologies would produce expertise that would provide a strong foundation for industries that could last for centuries, rather than, by contrast with nuclear technology, one century.

Technologies' lifetimes

Technologies have their lifetimes.

Steam power has lasted roughly 250 years. The internal combustion engine may last (it first appeared in 1850) 200 years.

Nuclear power looks set to last for 150 years at the most.

Water power (mechanical) has been around for at least 2000 years and will probably never go away.

Electricity as a clean means of conducting energy may also be around now as long as we are.

Renewable technologies generating electricity and heat will obviously improve and change with innovation, but they will be around also as long as we are, it's safe to assume.

What the government says

In the long-run we believe increased prices and global demand will help maintain reliable uranium supplies, thus not representing a constraint on any new nuclear build in the UK.
This is not a long run in my books. It is a medium term run as it is looking not 85 years but 15 years into the future.

The report begins by saying
In the short term, the main concern is the extent to which
we can be confident that energy can be delivered when and
where it is needed, i.e. reliability.
In the medium term, the focus is on the availability of
infrastructure, the planning process and supply chain issues
such as the availability, both within the UK and
internationally, of raw materials, machine components and
project management and engineering skills.
In the longer term, there is a wider range of options open to market participants, including significant capital investment and the development of new technology. Given this, the key concern in this time-frame is likely to be the availability of primary sources of energy.
In this discussion, short term is therefore about up to 12 years (2020); medium term seems to be the same actually, as over the same period the same concerns apply, but might extend a further 10 years as the Grid infrastructure is updated; and long term is any time beyond this.

Governments usually can't see beyond the electoral term of office. They are therefore bound by the need to balance the books - they can't spend too much public money.

Nuclear power stations in general take twice as long to build as coal power stations - ten as opposed to five years.

It's therefore curious that nuclear stations are being backed by ministers as they neither address the short term issues or the very long term issues.

New build nuclear power stations will be up and running around 2020. They would last until around 2095, then the fuel runs out. And anyway they will be worn out.

Before then, there is plenty of time to implement 15% of our generating needs from renewables that are currently proven - wind power, ground source heat pumps, solar thermal, and solar electric.

In the medium term government policy should signal to the markets that they should invest In the newer technologies - marine current turbines, wave power, tidal power and more advanced solar photovoltaic generation.

In particular the more predicatable sources - marine currents, tides, geothermal, heat pumps - should be prioritised.

So that after 2020 these are increasingly phased in.

in the medium
term the electricity generating industry faces a substantial
challenge in ensuring delivery of the new generating
capacity that will be needed if demand continues to rise. [p 37]

All the more reason for speeding up the planning process.

[And we haven't even mentioned the very very very very long time that nuclear waste poses a threat for]. If Stonehenge had nen a nuclear reactor it would be well glowing still.

Germany eyes North Africa's sun

Having become a world leader in wind turbines and photovoltaic panels, Germany is now turning its sights onto solar thermal generation.

Harnessing the sun's energy on just 6,000km2 of desert in North Africa would supply energy equivalent to the entire oil production of the Middle East of 9 billion barrels a year, acording to the German Aerospace Centre. It believes that solar thermal power plants could supply 68% of North Africa's as well as all of Europe's electricity by 2050.

One company that agrees is Flabeg, a German manufacturer of parabolic trough mirrors. Its new mirror can concentrate 92% of the sun's rays onto an absorber tube with a diameter of 70mm or less. It expects to sell these to power stations in Spain and North Africa and is already supplying 210,000 to the 50 megawatt solar thermal power plant, Andasol II, in Spain — the biggest in Europe.

Europe's first commercially operating solar thermal tower plant went into operation in April in Sevilla, Spain, generating 11 MW. The German Aerospace Center has built an experimental solar thermal tower power plant in Julich, Germany, to be commissioned in 2008.

Local energy, especially renewable heat, needs more support - Gov Committee

The government should do more to support local energy, according to the House of Commons Trade and Industry Committee.

Preferring the term "local energy" to “microgeneration” because it "is easier to understand and less restrictive", it argues that "there is too much emphasis on electricity production and not enough on local heating schemes - household or community-based." Roughly 1.3 million homes replace gas boilers each year, and Centrica estimates that micro-CHP systems could displace as many as 30% by 2015. It suggests that new housing schemes be fitted with CHP district heating. Furthermore it complains that Government payback figures, particularly for solar water heating panels, are far too pessimistic.

It urges energy suppliers to offer local energy systems with energy efficiency measures as part of a package of services to customers. Planning restrictions on rooftop wind turbines and solar panels should be removed, incentives streamlined, and the electricity distribution firms must pay a proper market rate for any surplus produced by such systems.

It acknowledges thast most forms of local energy are not suitable for all locations or uses. Micro-wind power's potential is "in danger of being oversold", according to one witness, so the government must ensure adequate information is available to consumers.

It says smart metering will be an excellent tool for promoting energy efficiency and export measuring, and calls for a deadline of 1 July 2008 for establishing standards and interoperability and a national roll-out scheme as in Italy.

However, local energy "cannot make a significant contribution in the next decade to closing the capacity gap created by the decommissioning of coal-fired and nuclear power stations—local energy is not a panacea that will 'keep the lights on'."
