SSEN Distribution trials net zero solutions

Scottish and Southern Electricity Networks (SSEN) Distribution is running trials of new net zero solutions to replace the current fleet of fossil-fuelled generators used during power cuts.

The move, which is in line with its target to reduce carbon intensity by 80% by 2030, has seen SSEN carry out a test where it connected a large battery pack to the network through a substation in Slough, showcasing how a battery would perform in the event of a supply interruption.

SSEN said it deploys generators in certain circumstances to provide power if there is a prolonged outage on the network. As part of its net zero strategy, the company said it was “urgently pursuing longer-term solutions to eliminate emissions from its generator fleet”.

The firm also said in the coming months that engineers will test a range of battery electric and hydrogen-powered batteries to assess their performance, efficiency, and durability. The trials will then inform a procurement process to replace the existing fleet of generators.

Alongside future work, it has also cut emissions on current generators by running on the full fleet on Hydrotreated Vegetable Oil (HVO) instead of white diesel, reducing carbon monoxide and particulate matter emissions down by 30%. It is also free from aromatics and sulphur, and ahs avoided 752 tonnes of CO2 emissions since the start of this year.

Richard Gough, SSEN’s Head of Region for Thames Valley, said:

“Here at SSEN, we have a deep, enduring commitment to help deliver net zero, and we’re always looking for viable solutions to get us there quicker, expanding our experience and knowledge as we go. That’s why we’re leading the way in these extensive trials of alternatives to current fuel-powered generators.

“This process has now taken another big step forward with the deployment of a battery-powered generator on the actual network, which successfully kept customers connected. This is just one of a series of trials we’ll be conducting over the next few months, where we’ll assess the suitability of a range of solutions which are new to the market.

“Having a culture where we’re always testing new tech means when the time comes to procure one of these solutions, our customers and stakeholders can be reassured we’ve run a thorough process to ensure we provide them with a safe and affordable solution.”
