National Grid has nailed its colours firmly to the electricity mast after buying Western Power Distribution (WPD) for £7.8 billion and announcing its intention to sell its majority stake in National Grid Gas as it strives to play a 'central role' in delivering UK net zero emissions by 2050.

In submissions to the London Stock Exchange yesterday detailing the proposed WPD acquisition and portfolio repositioning, National Grid said it will commence a process in the second of this year for the sale of a majority stake in National Grid Gas (NGG), the owner of the national gas transmission system. At 31 March 2020, NGG had approximately 7,630kms of pipeline and workforce of nearly 2,200 employees. 

"The Board anticipates significant buyer interest given NGG's high-quality operations, proven delivery, the strategic nature of the business, its regulatory certainty following the RIIO-T2 determination and the key role that the network will have to play in the energy transition," it states. Reports have indicated National Grid could raise around £2 billion from selling a 51 percent stake.

With regards to the WPD acquisition, National Grid highlighted six benefits:

  • It allows National Grid to bring together two complementary businesses
  • WPD represents a "one-off opportunity" to establish a significant scale position in UK electricity distribution, enhancing National Grid's key role in the delivery of net zero carbon emissions
  • WPD and electricity distribution will add significant growth potential to National Grid
  • WPD has a high quality asset base with track record of performance
  • WPD has a highly experienced management team and "excellent stakeholder engagement"
  • The NECO sale is a key differentiator for the WPD acquisition

The renewed UK focus also coincides with National Grid selling its American business, The Narragansett Electric Company (NECO), to PPL Energy Holdings for £2.7 billion. NECO supplies electricity and gas in Rhode Island to around 780,000 customers.

John Pettigrew, Chief Executive of National Grid, said the transactions will be transformational for its UK portfolio. 

"Establishing National Grid as the leading electricity transmission and distribution operator in the UK will strengthen our long-term growth prospects, enhance our role in the UK's energy transition and drive long term shareholder value," he said. "Following the completion of these transactions, we will continue to have a diversified portfolio of assets across the UK and US, with a strong asset growth profile that will further underpin our dividend policy for the longer term."

Given the strategic nature of its business coupled with its central position in a transition towards a hydrogen economy, NGG will continue to play a vital role in the UK's energy system, he added.


In another significant move, somewhat eclipsed by the financial deals, National Grid said it is exploring the development of a UK hydrogen ‘backbone’, which aims to join together industrial clusters around the country, potentially creating a 2000kms hydrogen network, connecting the Grangemouth, Teesside and Humberside clusters, as well as linking up with Southampton, the North West and South Wales clusters. 

Repurposing around 25% of the current gas transmission pipelines, Project Union will build on the government’s 10-point plan to invest more than £1 billion to unlock the potential of hydrogen and support the establishment of carbon capture, utilisation and storage (CCUS) in four industrial clusters.

Antony Green, Hydrogen Project Director at National Grid, said hydrogen has a critical role to play as we transition to a cleaner energy future. "The potential is exciting and a hydrogen backbone to support the industrial clusters could accelerate the roll-out. But there is a lot of work to find the most economic way to repurpose our assets and how we might develop a phased conversion to develop a hydrogen network for the UK."

Hydrostor receives $4m funding for A-CAES facility in Canada

Hydrostor has received $4m funding to develop a 300-500MW Advanced Compressed Air Energy Storage (A-CAES) facility in Canada.

The funding will be used to complete essential engineering and planning, and enable Hydrostor to plan construction. 

The project will be modeled on Hydrostor’s commercially operating Goderich storage facility, providing up to 12 hours of energy storage.

The project has support from Natural Resources Canada’s Energy Innovation Program and Sustainable Development Technology Canada.

Hydrostor’s A-CAES system supports Canada’s green economic transition by designing, building, and operating emissions-free energy storage facilities, and employing people, suppliers, and technologies from the oil and gas sector.

The Honorable Seamus O’Regan, Jr. Minister of Natural Resources, said: “Investing in clean technology will lower emissions and increase our competitiveness. This is how we get to net zero by 2050.”

A-CAES has the potential to lower greenhouse gas emissions by enabling the transition to a cleaner and more flexible electricity grid. Specifically, the low-impact and cost-effective technology will reduce the use of fossil fuels and will provide reliable and bankable energy storage solutions for utilities and regulators, while integrating renewable energy for sustainable growth. 

Curtis VanWalleghem, Hydrostor’s Chief Executive Officer, said: “We are grateful for the federal government’s support of our long duration energy storage solution that is critical to enabling the clean energy transition. This made-in-Canada solution, with the support of NRCan and Sustainable Development Technology Canada, is ready to be widely deployed within Canada and globally to lower electricity rates and decarbonize the electricity sector."

The Rosamond A-CAES 500MW Project is under advanced development and targeting a 2024 launch. It is designed to turn California’s growing solar and wind resources into on-demand peak capacity while allowing for closure of fossil fuel generating stations.

Hydrostor closed US$37 million (C$49 million) in growth financing in September 2019.
