National Grid warns of 'tight margins' in coming days
National Grid is warning UK consumers and businesses that its cushion of spare capacity has been cut due to low winds and a number of generator outages.
Yesterday it reported its margins are "adequate" for Thursday but it is "monitoring how the situation develops," according to its Twitter feed.
Last month National Grid issued an official warning to the electricity market that its ‘buffer’ of power reserves had fallen below 500MW and it may need to call on more power plants to help prevent a blackout, although the notice was later withdrawn.
The warnings coincide with the launch of the IFA2 interconnector subsea cable, linking France and Britain's power grids, which is seen as an important step in accelerating progress to a cleaner and greener future. The 1,000MW link can "decarbonise a million homes," according to Jon Butterworth, Managing Director National Grid Ventures. It aims to cut greenhouse gas emissions to customers by 20 percent by 2030.
In August last year, a major power cut left large parts of England and Wales without electricity, impacting road and rail services.
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.
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.
