National Grid Electricity Transmission has issued a call for ideas for low-carbon alternatives to the diesel generators it currently uses to provide backup power to substations.
The company said there are backup generators at more than 250 of its sites across England and Wales, the majority of which are diesel powered. These diesel generators are used alongside batteries to power key activities such as cooling, pumping and lighting during loss-of-supply events.
Although there are low-carbon diesel fuels available on the market, National Grid said it wants to support the adoption of new technologies by exploring other alternatives.
National Grid said its call for innovation, which is being supported with funding from Ofgem’s Network Innovation Allowance, is looking for third-party suppliers who can provide:
- Low emission, backup power systems or combined standby and generation assets
- Products that are of an optimised design to ensure space efficiency
- Products that require minimal civils works to install
- Have an interface with supervisory control and data acquisition
Ben Kuchta, innovation engineer for net zero innovation at National Grid said: “As the electricity transmission owner for England and Wales, we play an important role at the heart of the UK’s transition to net zero.
“It’s important we lead by example, reducing our own emissions and working with others to enable and accelerate the transition to net zero.
“Finding new low carbon alternatives to diesel generators is another step on that journey and we encourage suppliers to come forward.”
