Building energy storage projects next to wind farms cuts electricity system costs
A NEW report by RenewableUK shows that building more energy storage projects alongside onshore wind and solar farms reduces electricity system costs, benefitting billpayers in the long term.
These storage projects are also vital in providing flexibility in our clean energy system to ensure it continues to meet electricity demand at all times, especially as demand is set to grow with the take-up of technologies such as electric vehicles.
The report, entitled “Making the most of renewables: the role of onshore co-location in accelerating an integrated energy system”, sets out the case for reforming the planning system and introducing financial support mechanisms to encourage more battery storage and green hydrogen projects to “co-locate” at sites where clean electricity is generated throughout the UK. This means they could be built on wind and solar sites which already have planning permission and share existing grid connections rather than having to wait for years in a queue, saving time and money.
The queue of all energy projects awaiting connection has now reached over 700 gigawatts (GW) according to National Grid statistics, of which 97GW are battery storage projects. To put this into context, the UK’s entire operational wind capacity (onshore and offshore) currently stands at nearly 30GW.
Co-locating solar projects with battery storage could reduce the cost of building and running battery projects by 50%. And cumulatively, research by the Carbon Trust suggests that enabling a more flexible energy system with storage would save the UK up to £16.7 billion a year by 2050 in electricity system costs, ultimately benefitting bill payers.
RenewableUK’s EnergyPulse database shows that at present only 12% of wind and solar farms throughout the UK are co-located with batteries or hydrogen electrolysers, but the report states that has the potential to surge in the years ahead to meet the expected increase in electricity demand if the right policy framework is put in place.
The report calls for National Grid ESO to identify and quantify the value of the flexibility which co-location offers to a net zero system, as this would stimulate new investment. The wide range of measures also include providing new streamlined guidance for planning authorities to bring forward projects, and resourcing planning bodies better to enable decisions to be taken more swiftly.
The innovative “energy parks” which combine renewables and storage produce a more constant supply of clean electricity, which helps to tackle the issue of variability; in high winds, the grid cannot always cope with the vast amounts of clean power being generated by wind, and although some grid upgrades are underway, other solutions are needed to make the best use of the UK’s abundant renewable energy resources.
The report’s author, RenewableUK’s Senior Policy Analyst Yonna Vitanova, said:
“The value of storage in our modern energy system is under-appreciated and under-valued. This has to change if we’re to make the most of innovation clean technology, drive people’s electricity bills down and increase Britain’s energy security.
“The growth of much-needed energy storage projects, co-locating alongside wind and solar farms, is currently being hindered by out-dated policies and regulations which were drawn up in a different era. There isn’t even a clear definition of co-location applied consistently across planning policies, grid and market arrangements – which is one of the factors hindering the speed of deployment of co-located projects.
“Renewable energy developers should be able to include co-location in their business plans more easily, with a clearer rules and regulations being put in place to unleash the benefits which co-located projects can provide to the system and ultimately to consumers. Building a more flexible system by tackling the current barriers to co-location will require a coordinated effort and a holistic strategy cutting across markets, grid, planning and technical barriers, as this report shows. Although this is challenging, it will ultimately benefit billpayers in the long term by cutting electricity system costs”.

Impact of Storm Darragh on NRW’s woodland estate ‘significant’
AS THE NATION continues to recover from the significant impacts of Storm Darragh’s 90mph winds and rainfall (7 and 8 December), Natural Resources Wales (NRW) is continuing the challenging task of assessing the damage to its forests and nature reserves and working hard to restore its sites for visitors to return.
NRW’s land managers have been working hard across Wales to assess the damage to the land in its care, prioritising clearing trees from forest roads that have blocked forest resident access to their homes, and enabling emergency services and utilities to restore power and services to the public.
Early indications are that the impact on the Welsh Government Woodland Estate is significant with large areas of trees fallen in widespread areas across Wales.
Many kilometres of forest roads, walking trails and mountain bike routes are obstructed by fallen trees and branches and it will take time to clear them.
While this important work to restore access to trails continues, people are currently advised not to travel to NRW’s forests and reserves. While visitor centres are re-opening following the storm, people should check NRW’s website before planning a visit as car parks and other facilities may need to be closed at short notice as recovery operations continue.
The recovery work will focus on making sure trails and forest roads are accessible. Visitors should follow any instructions given by signs or local staff, including any trail diversions or closures and beware of the dangers of falling trees and branches.
Gavin Bown, Head of Operations Mid Wales for NRW, said: “Storm Darragh impacted communities right across Wales, with thousands of homes experiencing power cuts, and communities impacted by fallen trees and flooding. Our sympathies go out to those affected.
“The storm has taken a significant toll on the land in our care as well. A huge amount of work went into preparing for and responding to Storm Darragh, and the improved weather this week has allowed us to start the long road to recovery.
“We’re inspecting our sites to assess the damage, and our land managers and contractors are prioritising work to clear blocked roads and trails. But this will take some time. The impacts we have seen will likely affect planned forest and harvesting operations for years to come.
“While we’re undertaking that important work to get your trails back to normal, those who use them for recreation are advised not to travel to our sites at this time.
“We are providing the latest information about the status of specific sites and trails on our website, and on our social media channels. You should always follow any instructions given by signs or local staff including any trail diversions or closures, and beware of the danger of falling trees or branches.”

Push to speed up planning process ‘risks sidelining public opinion’
CHANGES to planning law risk sidelining the voice of the public in decisions on significant new energy projects, Senedd Members warned.
Plaid Cymru’s Luke Fletcher said accountability in planning decisions will be undermined by new regulations on major projects, known as developments of national significance (DNS).
Mr Fletcher told the Senedd the regulations will raise the threshold at which energy projects are decided by Welsh ministers from 10MW to 50MW, marking a fundamental shift.
The shadow economy secretary said: “Projects that could have considerable impacts on communities, landscapes and ecosystems will now receive less scrutiny, with the decision making process potentially expedited at the expense of … thorough democratic oversight.
“While we recognise the need for efficiency in the planning system, this cannot come at the cost of transparency and community involvement.”
Mr Fletcher told the Senedd that energy projects under 50MW can have profound effects, so it is vital communities have a meaningful voice.
“Yet these regulations risk sidelining that voice in the interests of speed and convenience,” he warned as he called on the Welsh Government to reconsider the reforms.
Raising concerns about the transfer of decision-making powers from Welsh ministers to appointed inspectors, he said: “Public confidence in the planning process depends on a system that is not only efficient but fair, transparent and open to challenge.”
He supported action to meet net-zero targets but said this must be done in a way that respects the rights of communities and safeguards the natural environment.
Mr Fletcher told the debating chamber or Siambr: “By prioritising speed over scrutiny, these regulations fail to strike that right balance.”
But Rebecca Evans, Wales’ economy secretary, said: “I’m afraid Plaid Cymru seems to have completely misunderstood the regulations which are being debated today.
“The application and determination process doesn’t change at all with the delegation of determinations to inspectors. The community engagement statutory consultees and the policy framework all remain exactly the same.”
Ms Evans, who is responsible for planning and energy, added: “Just to emphasise again that there is no change whatsoever to requirements around community engagement….
“So, the fundamental objection that Plaid Cymru has … doesn’t have any foundation at all.”
She said the regulations are an interim arrangement until the Infrastructure Act, which was passed by the Senedd this year, comes into force in September 2025.
The consenting process for major infrastructure projects will be overhauled under the Act, with the DNS system replaced by a streamlined regime.
The Senedd voted 36-12 in favour of the regulations which will come into force in January.

Pembrokeshire group plans for larger community wind turbine
A NORTH Pembrokeshire group which has raised more than £76,000 from its community wind turbine for local projects is hoping to expand with a bigger turbine.
In an application to Pembrokeshire County Council, Abergwaun Community Turbine Ltd, through agent Machynlleth-based Dulas Ltd is hoping to get permission for a larger turbine to replace the existing Abergwaun Community Turbine.
The proposed turbine, in a pasture field at Trebover Farm, to the south of Fishguard, would be 67m tall, the existing 2015 one being 45 metres.
In supporting statements, parent company Transition Bro Gwaun said: “The Community Climate Fund (CCF) is the mechanism by which Transition Bro Gwaun (TBG) is fulfilling our ambition of funding projects in Fishguard, Goodwick and across North Pembrokeshire, using income from the community wind turbine.
“The core themes for grants are climate change mitigation and adaptation, enhancement of biodiversity and improvements to community resilience through promotion of community engagement and resource sharing.”
In 2015, TBG raised its 50 per cent share of capital funding for the project by means of loans from 28 local individuals and four community groups, contributing a total of £286,500, the other 50 per cent contributed by landowners Parc-y-Morfa Farms Ltd.
The statement added: “Profit generated by sale of electricity from the turbine is split 50:50 between TBG and Parcy-Morfa Farms Ltd through the jointly owned trading arm, Abergwaun Community Turbine. By the end of 2022, all loans had been repaid, allowing the launch of TBG’s Community Climate Fund. This year we have awarded our third round of grants bringing the total amount granted to £76,036.”
In 2022, £15,274 was awarded to seven projects, including Fishguard Sports AFC to install solar panels on their clubhouse as part of their Tregroes Park development, Ysgol Bro Gwaun for their Increasing Biodiversity and Bees project, and Nevern Valley Veg / Llysiau Cwm Nyfer to install a solar powered vegetable irrigation scheme.
In 2023, £39,85 was made available for seven projects, including Sea Trust Wales to part fund the installation of solar panels on the Ocean Lab roof and to produce a display on solar technology, Letterston Memorial Hall to part fund the installation of an air source heat pump heating system, and Fishguard and Goodwick Rugby Club to install solar panels on their clubhouse.
2024 awards of £20,917 were made to six projects, including Theatr Gwaun to insulate their loft to reduce heating loss, Parc Cerrig Growers for developing a rainwater harvesting system with a pond to irrigate their allotments, Caerhys Organic Community Agriculture for an electric cargo bike for delivering organic vegetables in the Fishguard and St Davids areas, and Nevern Valley Veg to develop wildlife ponds and rainwater harvesting for food production.
The supporting documentation concludes: “The repowering of the existing turbine at Trebover would require a limited increase in turbine size which would result in a very limited change in landscape and visual effects in comparison to the existing Trebover turbine.”
The application will be considered by planners at a later date.
