We deliver value for our partners. Our track record speaks for itself.
Since formation, Welsh Power’s team has grown substantially with our unique entrepreneurial spirit setting us apart in the UK Energy Sector. We have continuously sought new opportunities created by an energy market that is constantly seeing significant change and challenge.
Our Rothienorman project completed construction and is now providing grid stability services to NESO. This is our first in Scotland and is the first synchronous condenser from the NESO Pathfinder 2 tender to enter commercial operations.
Construction of PF2 projects ongoing
Rassau Synchronous Condenser completed construction and begins providing inertia to National Grid
Welsh Power developed projects awarded four Stability Pathfinder Phase 2 projects in Scotland. Stability Pathfinder Phase 2 is focused on providing short-circuit level and inertia in Scotland.
Welsh Power is managing the construction and will operate the facilities.
Welsh Power awarded two projects to deliver new stability services across England and Wales as part of Stability Pathfinder Phase 3.
Welsh Power expands its services into the development, construction and management of battery storage facilities. Welsh Power is developing a pipeline of battery projects across the UK and managing the construction and operations of a 20MW battery storage site.
Welsh Power grow the portfolio of flexible generation facilities under their management by 122MW – bringing our total MW under management to 550MW
Our first grid stability project was awarded a pathfinder contract to provide services to National Grid ESO in South Wales, with construction of a synchronous condenser and flywheel beginning soon after. We are managing the construction and will operate the plant. The plant will have a vital role in managing the stability of the electricity system and facilitate the deployment of more renewable energy, as we target the goal of operating the electricity system carbon free.
Welsh Power’s Health, Safety, Environmental and Quality Management System was accredited and certified to: ISO45001:2018 (safety); ISO14001:2015 (environment); and ISO9001:2015 (quality). The accreditations demonstrate our ongoing commitment to safety, environment and quality.
We expanded our service offering to include developing grid stability facilities – a new market in the UK. We continue to work on a pipeline of developments across the UK, with facilities that will support National Grid Electricity System Operator's goal of operating the grid carbon-free by 2025.
In 2018, we became a fully employee-owned organisation providing us with a robust and aligned ownership structure from which to deliver the next stage of our growth.
A portfolio of some 50MW of peak power plant was sold to Alkane Energy Limited.
Welsh Power formed a strategic partnership with a financial investor, leading the development, construction and operation of a new, extensive portfolio of 26 flexible, high efficiency, low emission gas fired reciprocating engine power plant. Totalling nearly 430MW, the assets support the energy transition towards a net zero carbon energy system.
The Welsh Power team acquired the business in an MBO. The team embarked on a new phase focused on small-scale distributed gas generation aimed at supporting changes in the underlying nature of the UK’s energy system.
Severn Power Limited, an 850MW CCGT plant in South Wales was sold to DONG Energy.
Haven Power was sold to Drax Power plc. At the time, it was one of only a small number of successful energy supply start-ups in the UK since privatisation of the sector.
Uskmouth Power Limited, the 360MW coal plant that we had given new life to, was sold to SSE.
Construction began on Severn Power Limited, an 850MW CCGT plant near Newport which was developed by Welsh Power. We raised in excess of £600m of debt and equity finance to fund this major project.
It is the only major UK gas plant that has been developed, financed and built by an independent energy company in the last 25 years.
Haven Power, an electricity supply business for commercial and industrial customers, based in Ipswich was launched. Within two years, Haven was a major independent energy supplier with some 25,000 SME customers, turning over £100m and with the systems and process to robustly manage the customer base.
With backing from Rutland Partners, Welsh Power acquired Uskmouth Power Limited, a 360MW coal plant and brought it back into service. Uskmouth became one of the most reliable plants in the UK and is recognised as a true turnaround success.
How we deliver
Welsh Power’s asset management activities cover development, funding, construction, operation, financial management and optimisation of assets.
Welsh Power’s asset management capabilities cover development, funding, construction, operation, financial management and optimisation of assets.
Welsh Power is the UK’s leading provider of asset management services to the flexible generation market. We have an established reputation within the broader UK energy sector as an independent operator and market innovator.
We have been at the forefront of the evolving commercial and regulatory developments. We have operated in the flexibility space since 2008 and have been instrumental in the development of the long-term STOR service and participated in the Capacity Market since its inception.
Now with 730MW under management and a series of grid stability projects in operation, construction and development, Welsh Power plays an important role in supporting a UK electricity network which is increasingly reliant on zero carbon but intermittent renewable energy sources.
Welsh Power provides a comprehensive asset management service including project development, funding, construction, operation, financial management, optimisation of assets and much more. We are unique in being a dedicated service provider with a breadth of experience in the energy market offering an unrivalled capability to effectively manage Projects and offer a bespoke service, tailored to our customers’ requirements.
We currently manage 47 individual assets for our clients, totalling over 730MW of generating capacity. Over half of this capacity was developed by Welsh Power’s in-house development team. These assets play a key role in enabling the UK to decarbonise ensuring there is sufficient flexibility available to the electricity network as output from renewable sources vary across the day and seasons.
Welsh Power has used its skills, experience and knowledge to pursue strategic investment in grid stability, inertia and dynamic containment services, which play a key role in supporting a reliable decarbonised electricity network. These technologies strengthen the national electricity system and paves the way for the National Electricity System Operator (NESO) to operate the grid using more renewable electricity, replacing many of the network services historically provided by large coal and gas fired power stations. Welsh Power’s Rassau development was one of the first to be awarded a long-term contract for stability services in NESO’s stability pathfinder phase one tender and Welsh Power followed this up with successes in phase 2 and 3 of NESO’s stability pathfinder tender securing contracts for a total of seven separate stability assets. Our Rothienorman development was the first of NESO’s pathfinder phase two tender projects to enter commercial operations at the end of 2024.
Working closely with our partners, Welsh Power is providing clean, flexible, distributed power and innovative grid stability solutions to support the UK’s transition to a net zero sustainable energy system.
