National Grid and SS to use electric transformers to heat homes

As part of new plans to use “heat dissipation” and reduce carbon emissions from home heating, thousands of homes could soon be heated from giant grid transformers.

Experiments on how to handle heat generated by national grid-owned network transformers begin with home heating for families connected to SSE district heating networks.

Hot air is now being pumped out of the huge distributors to cool the transformers that help control the electricity running on the national grid high-voltage transmission lines.

However, if successful, about 1,300 national grid distributors will soon be using SSE services in neighboring boilers, hot water from nearby heating networks, and thousands of homes.

“Electric transformers generate a large amount of heat when electricity flows through them. This heat is now being released directly into the atmosphere, ”said Nathan Sanders, manager of SSE Energy Solutions.

Sander added, “This infrastructure project aims to capture that waste heat and convert local heat networks into low-zero or carbon-alternative alternatives such as gas boilers to community boilers. .

Alexander Yanushkvich, National Grid Innovation Manager, said the program was important for “achieving a net zero” and that “Britain is leading the way in helping accelerate decarbonation.”

Energy companies initially believe the program could reduce carbon emissions by more than 40% compared to fossil gas systems. If the UK’s electricity system is zero carbon, the heating solution could play a big role in helping the UK meet its climate goals.

The first experiments to test how liquid heat can be used in district heating networks were launched at the National Grid test site at Dessie in Wales. Once completed, the intellectual property will be shared with small regional power network owners, who will choose to run projects in their area.

“We have 1,300 transmission transformers in the national grid, but there is no reason why this technology should not be applied to small power transformers,” said St.

Once the experiments are completed, National Grid and SSS will have a better idea of ​​how many homes can be heated using the electricity available from the distribution network, Aureley said, and how the heat can be used.

“The hard [electricity] Load, usually at peak hours around the clock, can generate more heat. So it is ideal for people who need warmth at night. ”

Other projects designed to capture waste heat in the district’s heating programs include the use of heat from the North Tube London network to heat homes in Islington and the use of geothermal heat from landmines not used for district heating networks in Durham.

Between 2% and 3% of the UK is connected to the district’s heating network, compared to most homes in Germany and Scandinavia. But in the years leading up to the UK’s efforts to reduce carbon emissions, more heating networks are expected to emerge.
