Net-zero Wales and the generation game

THIS WEEK’S episode of Panorama explored the significant clean energy projects creating tension across Britain.

“Rewiring Britain: The Race to Go Green” examined the UK’s efforts to create a greener, more sustainable energy infrastructure. It highlighted the challenges and opportunities associated with reducing carbon emissions, increasing renewable energy sources, and modernizing the national grid.

The programme incidentally highlighted an unusual set of data about Wales’s contribution of net-zero energy to the UK’s National Grid.

BBC Reporter Justin Rowlatt visited the headquarters of the National Energy System Operator (NESO). NESO ensures that Great Britain has the necessary energy by matching supply with demand every second of every day.It also monitors the contributions made to the UK energy grid from net-zero sources.

In a cutaway shot establishing that just over half of the UK’s energy came from net-zero sources.
The UK is divided into six distribution network licence areas, as shown in the screenshot accompanying this article.

What draws the eye, at least Welsh eyes, is the amount of net-zero energy provided by the area covering South Wales and South West England.

That amount was zero on the day the BBC attended NESO HQ. Given the number of large green energy infrastructure projects in South Wales, this seems astonishing. It is even more astonishing when one considers the large green energy projects across the South West of England.

An examination of the data underlying the chart shows why that is the case: almost three-quarters of ALL energy generated in South Wales comes from fossil fuels. That means that all of the net-zero energy generated in South Wales is consumed in the region and is not exported as surplus to the UK Grid.

To check our conclusion we asked NESO a series of questions, the answers to which confirmed that South Wales (the figures for North Wales are in the North West area on the screenshot), was not a net exporter of green energy to the grid.

When we checked earlier this week, we confirmed that was still the case.

Those data appear to run a coach and horses through claims that Wales is leading the way in green energy.

As it stands, South Wales isn’t even generating enough net-zero energy to power homes and businesses across South Wales. As planned green energy projects, such as the controversial plan to erect a chain of pylons and windfarms across rural Wales, focus on energy production for homes and businesses outside Wales, the benefits to the South Wales economy of supposedly “green” infrastructure projects appear marginal.

The UK government asserts that building new pylons, solar plants, wind turbines, and electricity substations is essential for achieving its ambitious goal of decarbonizing the country’s electricity by 2030. To expedite these projects and stimulate the economy, the government plans to “streamline” the planning process. However, many protesters contend that this approach risks overlooking their objections.

While some praise the UK government’s reforms, which aim to accelerate energy projects, there has also been significant criticism. Many stakeholders—including environmental groups, local communities, and planning experts—express concerns about the erosion of local democracy and community input. Critics warn that these proposed changes may undermine local decision-making by prioritizing national targets over community interests and feedback.
Despite the necessity of green energy projects for reducing carbon emissions, there are worries that large developments, such as solar farms and wind turbines, could negatively impact local ecosystems and biodiversity if not carefully managed.

Furthermore, the government faces criticism for not adequately addressing how to balance the need for renewable energy with other priorities, including housing development and infrastructure. The use of agricultural land for solar farms or bioenergy crops raises additional concerns about food security and the loss of productive farmland.

Large-scale renewable projects, especially wind turbines, can significantly alter landscapes. This has led to resistance from residents and conservationists who value the rural areas’ visual and cultural heritage. For example, in Lincolnshire, proposed solar farms are set to cover an area larger than Greater Manchester. Critics argue that the government’s focus on large-scale projects overlooks the potential benefits of smaller, community-led initiatives and energy efficiency measures, which could also play a crucial role in decarbonization.

The drive to achieve net zero, or at least energy self-sufficiency and energy security, is admirable in intent. However, marrying ambitions and outputs with the views of those whose homes, land, and lives will be most affected by the infrastructure and structures needed to support them is as far away as ever.

A MAJOR construction materials company has signed a long-term deal to use renewable energy from Welsh windfarms as part of efforts to cut carbon emissions.

Energy firm RWE has agreed a 15-year contract to supply electricity to Breedon Group plc, which operates sites across Great Britain producing materials including concrete, asphalt and cement.

Under the agreement, RWE will provide around 70 gigawatt hours of renewable electricity each year from its windfarm portfolio.

The power will initially come from the Gwynt y Môr offshore windfarm, about 24km off the coast of North Wales in the Irish Sea. From 2033, supply will switch to the Brechfa Forest West onshore windfarm in Wales.

The electricity will support the production of key building materials, helping Breedon reduce emissions linked to its energy use in a sector widely regarded as difficult to decarbonise.

RWE said the agreement highlighted the role renewable energy can play in helping heavy industry move towards lower-carbon operations.

Olaf Lubenow, head of commodity solutions at RWE, said: “This agreement underlines our commitment to supporting the construction materials sector on its journey towards a more sustainable future.

“By supplying renewable electricity from our wind portfolio, we are helping to reduce the carbon footprint of Breedon’s operations.”

Breedon said the deal would also provide long-term energy stability while supporting its wider sustainability plans.

Donna Hunt, the company’s sustainability director, said the agreement marked “a meaningful step forward”.

She said: “It secures long-term energy supply and helps accelerate the reduction of emissions from our operations.”

The company has set targets to cut emissions across its business by more than 20% by 2030 and to reach net zero by 2050.

The agreement reflects a growing trend of major industrial firms turning to renewable energy to help meet climate targets while managing rising energy costs.

Pembroke Power Station National Grid shutdown power plans

A CALL to site specialist diesel generators at Pembroke Power Station to help keep the lights on in the event of a National Grid shutdown has been lodged with county planners.

In a screening application to Pembrokeshire County Council, RWE Generation UK PLC, through Ove Arup & Partners Ltd, wants to site up to six containerised diesel generators, diesel storage tank(s) and electrical connections at Pembroke Power Station, Pwllcrochan, near Pembroke.

The application site is within the site of the existing Pembroke Power Station, a combined-cycle gas turbine (CCGT) station which began commercial operation in September 2012, with a gross consented capacity of about 2,199 megawatts electric (MWe), replacing the previous oil-fired power station which operated for almost 30 years and was decommissioned in 1999.

A supporting statement says, subject to confirmation, it is considered to comprise permitted development, the scheme “a standalone plant, with its own fuel supply, capable of starting up, operating and shutting down independently from the power station”.

It adds: “It is required only in an emergency to maintain plant status and keep the power station operationally ‘ready’ in the event of a total or partial shutdown of the National Grid system. It is not required for the normal operation of the power station and does not extend its capacity, which remains as already consented, therefore it is not considered a change or extension.”

On need, it says it is mandatory that all electricity generators of over a megawatt have to adopt a new minimum standard of asset resilience; power stations “must be capable of restoring demand on the National Grid electricity transmission system in the event of a total or partial shutdown of the National Grid system”.

“The Power Station does not currently meet this new asset resilience standard, therefore new back-up power, control philosophy and on-site services that support site critical systems enabling the power station to remain ready to operate must be implemented.

“RWE is required to install a new enhanced emergency site auxiliary solution (diesel generators and diesel storage tanks) at the power station for resilience against the failure of the interconnected electricity distribution network into which it is normally connected in order to satisfy the Grid Code requirements by the mandated implementation deadline of December 31, 2026.

“RWE will make operational and fuelling provision, within its new resilience design at Pembroke power station of up to 120 hours, in order to provide capability to a slightly enhanced standard known to be valued by the National Energy System Operator (‘NESO’) in certain emergency network scenarios.”

It says construction is hoped to start in July 2026, lasting approximately nine to 12 months, the main part across the summer months.

The call will be considered by county planners at a later date.

PLANS for a green energy scheme at a Pembrokeshire former country house which is now holiday apartments have been given the go-ahead.

In an application to Pembrokeshire Coast National Park, HPB Ltd, through agent Acanthus Holden Architects, sought permission for a biomass boiler plant and installation of 16 rows of solar panels to the south of the tennis courts, St Brides Castle, St Brides, along with the removal of two tennis courts, two polytunnels, two sheds and relocation of a container.

Marloes and St Brides Community Council: Supporting

An officer report recommending approval said: “St Brides Castle. Listed Grade II* is a former country house (now holiday apartments) just south-west of the small settlement of St Brides.

“The house and its listed ancillary buildings stand prominently within a large grade-II-registered park and garden. The development site lies immediately south of the registered asset, outside of its boundary.”

It added: “Although in a sensitive location, the proposed scheme is well-screened, utilising an existing hedged enclosure. The proposed panels do not protrude over the hedge line, the proposed extra planting to the south and west providing further screening. The proposed building, also well-screened, is of traditional design, proportions and materials.”

The application was conditionally approved by park planners.
