Building energy storage projects next to wind farms cuts electricity system costs

Published

on

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”.

No current plans for clean air zones in Pembrokeshire

Published

on

PEMBROKESHIRE County Council has no current plans to introduce clean air zones or road user charging, councillors heard.

In a submitted question heard at the May meeting of Pembrokeshire County Council, member of the public Sharon Purcell asked: “In relation to the Environment (Air Quality and Soundscapes) (Wales) Bill, what advice has the council received regarding planned clean air zones or road user charging with a view to introducing schemes to address these issues in the future?”

She also asked a second traffic-related question: “Are there any plans for Local Traffic Neighbourhoods to be introduced and if so, where?”

Answering both questions, Cabinet Member for Residents’ Services Cllr Rhys Sinnett said there were no plans across Wales currently, under any guidance received for the first question.

He also said there were no plans for any Local Traffic Neighbourhoods in Pembrokeshire.

90 percent of Rhosygilwen turbine power would be sent to national grid

Published

on

A SCHEME for a £1m “20-storey-high” wind turbine to keep a listed Pembrokeshire mansion viable has been backed at a meeting of full council despite members hearing 90 percent of the power generated would be sent to the national grid.

Mr and Mrs Glen Peters of Western Solar Ltd sought permission for a single turbine on land near the Grade II-listed Rhosygilwen Mansion, which includes an arts and functions building known as Neuaddydderwen.

Mr Peters has previously said the application for a turbine would ensure the long-term viability of Rhosygilwen, acquired some 30 years previously as a fire-damaged house that was about to be pulled down.

He has said that, despite 200-year-old Rhosygilwen using power from its solar farm, the first of its kind in Wales, it has been hit with “huge increases in importing energy from the grid” during the winter months.

Planners have repeatedly been recommended to refuse the scheme by officers, but backed it at both their March and April committee meetings.

The March backing meant the application returned to the April meeting for ratification after a ‘cooling off’ period; the application having been deferred at the January meeting pending a site visit.

It was initially recommended for refusal in January for several reasons, including potential harm to the setting of the Grade-II-listed house and grounds, and fears of threats to the safe operation of West Wales Airport at Aberporth in neighbouring Ceredigion, some 9.5 kilometres away.

The last concern was later withdrawn.

Officers have said the scheme “would not protect or enhance the setting [of Rhosygilwen] but rather would result in significant harm to this interest of acknowledged importance”.

They have also warned any backing of the scheme against policy recommendations could set a precedent for similar developments.

As the scheme was from the development plan, the final decision had to be made by full council, meeting on May 9, where it was recommended the committee support for the scheme was not endorsed.

The scheme had been twice backed by the planning committee partly on the grounds of its contribution of green power to help tackle the ongoing climate emergency.

Speaking at the May 9 full council meeting, Councillor Tessa Hodgson questioned how much power from the proposal would be fed back into the grid and how much would go to power Rhosygilwen.

She was told that 90 percent from the “medium scale turbine” would be fed back into the grid, generating a tariff for the applicant, 10 percent powering the mansion and associated buildings.

Councillor Mike Stoddart described the amount of power produced by turbines as “miniscule,” saying it would require some 2,000 to equal the power output of Pembroke power station.

“It’s not going to make any material difference to the amount of carbon dioxide we output,” he told fellow councillors.

A move to approve the scheme, made by planning committee chairman Cllr Jacob Williams, was supported by 37 votes to 18, with two abstentions.

Objector Paul Robertson-Marriott has previously said the “20-storey” turbine would have “a detrimental impact” on surrounding properties and the proposal would “ride roughshod over the status of the listed building for economic benefit.”

Fears raised in Senedd over coal tip reclamation projects

Published

on

PROPOSALS to reclaim disused tips risk opening the floodgates to coal extraction under the guise of remediation, the Senedd heard.

Delyth Jewell led a Plaid Cymru debate on coal tip and opencast mine remediation, warning a new industry is emerging with reclamation coming at the price of coal extraction.

Ms Jewell, who represents South Wales East, raised concerns about Energy Recovery Investments Limited’s (ERI) proposals for reclamation of Bedwas tip.

Plaid Cymru’s deputy leader said: “Before the land is restored to its former glory, it seems it must be ravaged and plundered again.”

She said some make good on promises but others do not, “claiming at the end of projects that not enough money remains for restoring – it’s all gone on draining every drop of profit.”

Hefin David urged fellow members to keep an open mind to ERI’s plans to remediate coal tips in Bedwas in his Caerphilly constituency.

Dr David said: “We need to keep an open mind about any opportunity or avenue we have to remediate, but at the same time we must ask sceptical questions.”

He stressed: “This isn’t Ffos y Fran, this isn’t ‘leave it as a disaster zone and exploit the land.

“This is a company that is saying, ‘Yes, we’ll take the coal as a by-product and we’ll make a profit, but we are there to remediate the land.’”

Dr David added his voice to a chorus of calls for the UK Government to urgently provide additional funding for proper long-term remediation of disused tips.

Plaid Cymru’s Peredur Owen Griffiths raised concerns about the “troubling” proposals for a coal-extraction project in his South Wales East region.

Mr Owen Griffiths said ERI is planning to extract coal from the Bedwas colliery site over seven years, with a possible extension.

He told the chamber: “The potential implications of the project are far-reaching and alarming, with many questions yet to be answered satisfactorily to alleviate the concerns of residents.”

Warning it could set a dangerous precedent, with more than 300 at-risk coal tips in south Wales, he said the project risks allowing coal extraction under the guise of remediation.

Mr Owen Griffiths said: “It’s imperative that we ask many searching questions to guard against attempts to revive the coal-mining industry through the back door.”

Rhianon Passmore said people in her Islwyn constituency have deep concerns about ERI’s plans for the former coal tips at Mynydd y Grug in Bedwas.

Ms Passmore raised constituents’ concerns about 18 to 20 lorries a day travelling down a haul road that passes through the Sirhowy valley country park.

Pointing out that a planning application has yet to be submitted, she said: “While we want to see coal tips removed and remediated, it cannot and should not be at any cost.”

The Labour MS said the Welsh Government has committed £47m but the UK Government has yet to contribute funding for long-term remediation of disused coal tips.

She called for the UK Government to step up to the plate and take responsibility.

Sioned Williams said there are more than 900 disused tips in her South Wales West region, warning that the landscape has been scarred with environmental hazards left behind.

The Plaid Cymru MS raised the example of Godre’r Graig in the Swansea valley.

She said: “Due to an assessment of the risk of the quarry spoil tip to the village school, children have had to be educated in Portakabins miles away from the village since 2019.

“The school has now been demolished, causing absolute heartbreak in the community.”

Heledd Fychan, who represents South Wales Central, called for new legislation to reflect the realities of today, pointing out that the Mines and Quarries Act dates back to 1969.

The Plaid Cymru MS said: “It is absolutely appalling, in my view, that the UK Government has not played its part in helping to fund the work.”

Joel James, for the Conservatives, rejected Plaid Cymru’s “alternative reality” that paints Wales as a victim of exploitation during the industrial revolution.

“The truth is that our national resources were used to help to enrich us,” he said.

Mr James argued the UK Government should not be expected to pick up the bill for remediation while the Welsh Government brings forward proposed legislation on disused tips.

The South Wales Central MS said the Welsh Government has resources at its disposal, criticising the estimated £18m-a-year cost for 36 more politicians in Cardiff Bay.

Mr James said Wales should engage with ERI on remediation works.

Julie James – who could not comment on the Bedwas proposals – said her father was a miner who died of cancer, almost certainly because of his mining history.

She said: “That will be the case in many families across Wales. To say that that isn’t exploitation beggars belief, quite frankly.”

Wales’ local government and planning secretary urged the UK Government to recognise its moral responsibility to help fund remediation because coal tips long predate devolution.

Ms James said a forthcoming coal tips, mines and quarries bill will reform outdated laws around tip safety and give greater security to people living in its shadow.

MSs voted down Plaid Cymru’s motion, 12-45, with Conservative amendments also falling. The motion as amended by the Welsh Government was agreed, 41-16.
