National Grid issues Electricity Margin Notice
National Grid's Electricity Margin Notice (EMN) remains in place Wednesday evening, ahead of England returning to lockdown on Thursday, as it strives to increase its spare capacity buffer.
While the utility operator tweeted that the EMN is a "routine signal", demand has dropped around 10 percent in recent weeks and the notice serves as a clarion call for the market to provide more capacity. The system is likely to be particularly tight between 16.30-18.30GMT.
"The tight margins on the electricity system are the result of a number of factors including the weather, demand for electricity and availability of generators," it stated.
Last month UK consumers and businesses were warned that the grid's cushion of spare capacity had been cut due to low winds and a number of generator outages.
National Grid Partners, the investment and innovation arm of National Grid, recently announced two new investments in data analytics startups that use AI to protect critical infrastructure and reduce costs. NGP led both funding rounds with $6M in combined investment.
New additions to its portfolio are:
- Boston-based Aperio Systems, which uses AI and machine learning (ML) to analyse and monitor industrial sensor data in real time. Aperio’s data integrity platform enables customers in industries such as energy, mining and manufacturing to make better-informed decisions, reduce downtime and boost safety and security.
- Silicon Valley’s AiDash uses high-resolution satellite imagery coupled with AI to help utility and energy customers transform operations and maintenance activities like vegetation management, remote monitoring and disaster management. Its technology helps protect distribution grids from overgrown plant life that can spark disruptions or fires.
“National Grid’s ambition is to become the most intelligent transmission network in the world,” said Lisa Lambert, the company’s Chief Technology and Innovation Officer and the founder and president of National Grid Partners. “We are investing in and deploying technologies across our networks to enhance resilience and reliability, while more easily integrating clean energy.”
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.
