Social Energy Wins FFR Contract with National Grid ESO

Social Energy has won the first ever fully domestic contract with National Grid Electricity System Operator (ESO) to supply week-ahead Firm Frequency Response (FFR), following the results of a recent trial weekly auction.
 
The green energy supplier will use 80 per cent of its fleet of battery-powered customers to provide 4MW of FFR capacity to the ESO throughout the day. By enabling its customers to seamlessly take part in the weekly Frequency Response Auctions, Social Energy can ensure they benefit financially by maximising the trading opportunities through keeping a diversified portfolio, while supporting the future of energy. For further information see the IDTechEx report on Distributed Generation: Off-Grid Zero-Emission kW-MW 2020-2040.
 
Firm Frequency Response is one of the balancing services that the ESO uses to keep the electricity system in balance and ensure demand for power is matched by the levels of electricity generated. With thousands of domestic energy customers throughout Britain and the technology needed to take part, Social Energy is uniquely positioned to deliver this service with purely domestic assets.
 
 
The ESO is using FFR as part of its programme of work preparing Britain's electricity system to be able to run on purely zero-carbon electricity by 2025 - ready to accommodate whatever quantity of renewable electricity is being generated at that time.
 
The Frequency Response Auction trial is a two-year project to trial the procurement of a portion of ESOs frequency response requirement via weekly pay-as-clear auctions. The trial, which is funded by the Network Innovation Allowance, supports core ESO Forward Plan deliverables to remove barriers to entry, promote competition and deliver value for end consumers.
 
Social Energy is a new generation of energy supplier that uses smart technology to reduce its customers' electricity bills. Homeowners can get their solar and battery system from a local approved installer and connect it to the Social Energy tariff to reduce their electricity bills by up to 70% - saving a typical household £516 per year. By adding a battery and connecting it to Social Energy's smart technology, customers will maximise their solar energy usage, receive the best price for exporting their excess energy to the grid and automatically take advantage of low or even negative priced energy.
 
Steve Day, Chief Technology Officer at Social Energy, said: "It's fantastic to work with the National Grid ESO to supply frequency response solely from domestic assets as part of the weekly trial. By expanding our portfolio of grid services to include the frequency response auctions, it enables us to secure greater benefits for our customers, while helping to future proof the electricity system in Britain."
 
 
David Spencer, New Business Manager at National Grid ESO, said: "It's great to see a new approach in this market and a first contract made up entirely of domestic customers. Managing the frequency of electricity, through matching supply and demand is a key part of our role making sure Great Britain has safe, secure and reliable electricity. FFR is one of the many tools we use to balance the system. It's a great initiative helping us towards achieving our ambition of being able to operate the GB electricity system carbon free by 2025, with the services being used to balance the grid moving away from traditional sources to cleaner, decentralised power."
 
Notes
  • Social Energy is a new generation of energy supplier. It makes changing to renewable energy an easy choice for every homeowner, with solar panels and battery storage that is more profitable for households. Together with its customers, Social Energy can change energy for the better, by creating market-leading green tariffs - delivered through powerful yet easy-to-use apps. Its advanced technology and trading platform ensure solar energy and battery storage is financially viable - reducing its customers' electricity bills and maximising their green potential.
  • Up to 70% saving based on sample of 70 customers supplied by Social Energy over a 6-month period between January and June 2020. 42% of customers saved more than 70% on the electricity bill. Electricity bill savings are based on actual demand and solar generation measurements, and include: tariff savings by moving from their average previous tariff rate to a Social Energy import unit rate of 14.15p/kWh; reduced grid consumption due to direct and indirect solar self-consumption; payments for exported electricity at a rate of 5.6p/kWh, and payments for participating in specific flexibility services.
  • £516 saving figures are based on a 5.8 kWh battery, annual solar generation of 3500kWh and demand of 3800kWh, a SE unit rate of 14.15p/kWh, an SE export rate of 5.6p/kWh. and self-consumption rates taken from MCS Guidance Note MGD003 tables using the "In half the day" occupancy archetype after factoring in grid trading operations
  • National Grid Electricity System Operator is a legally separate business within the National Grid Group - relies on a mix of power generation to balance Great Britain's electricity system and ensure that, whatever the mix, electricity is always there when its needed.
  • Its mission is to enable the transformation to a sustainable energy system and ensure the delivery of reliable affordable energy for all consumers. It is working with stakeholders across the whole energy system to plan for future requirements on the electricity networks. It uses the insight it gathers to make sure it can balance the system today and find opportunities to transform the way it operates in the system in the future.
  • National Grid ESO is proud of the role it plays enabling and accelerating progress towards a low-carbon energy future. In May 2019, it reported the first ever fortnight of coal-free operation of Great Britain's system, showing further progress towards its ESO ambition of being able to operate a zero-carbon electricity system by 2025.
