SSEN Distribution is taking ‘bold’ action to reduce its emissions by running trials of new net-zero solutions to replace the current fleet of fossil-fuelled generators used during power cuts.
The organisation uses generators in certain circumstances to provide power if there is a prolonged outage on the network. Given its commitment to net zero, SSEN is ‘urgently’ pursuing longer-term solutions to eliminate emissions from its generator fleet.
A test has already been carried out which involved the connection of a large battery pack to the network via a substation in Slough. The test assessed how a battery would perform in the event of a supply interruption.
Over the coming months, SSEN engineers will test a range of battery electric and hydrogen-powered batteries to assess their performance, efficiency, and durability. These trials will inform a ‘rigorous’ procurement process to replace the existing fleet of generators.
In the meantime, in line with SSEN’s commitment to pursue every feasible opportunity to cut carbon, emissions from the current fleet of generators are being reduced significantly. Following a successful trial, SSEN is now working on making the full fleet run on Hydrotreated Vegetable Oil (HVO) instead of white diesel.
HVO is a low-carbon substitute, made from waste materials like used cooking oil. Assessments indicate the use of this fuel is having a big impact on air quality, with carbon monoxide and particulate matter emissions down by 30% compared with diesel. HVO is also free from aromatics and sulphur, which are both harmful to human health.
By using biofuels such as HVO, SSEN has 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.”
