Industry project sparks new approach to balancing a greener grid

Flexitricity is working with National Grid to help find new ways to stabilise the Great Britain’s electricity transmission system as the nation’s energy becomes greener and fossil fuels are phased out. - 

The news comes a week after the UK was powered without coal for a record three days in a row, using power generated from wind, gas nuclear and solar.

The Great Britain (GB) System Operator has found that as more renewable sources come into the system and larger, inertia-rich, generators such as coal-fired power stations drop out, maintaining the system frequency response at 50 Hz – a license requirement - has become more challenging. 

Demand response based aggregator Flexitricity is one of eight project partners from industry and academia working on National Grid’s Enhanced Frequency Control Capability (EFCC) project.  The project has recently developed a new monitoring and control system to manage an increasingly green grid.  This new system will help maintain system stability during peaks in supply and demand, drive savings for consumers.

Earlier this month the project was shortlisted at the British Renewable Energy Awards on behalf of National Grid for a company that has developed an outstanding project.

Flexitricity has recruited customers from industrial and commercial sectors for a demand side response (DSR) trial as part of the project which will also call upon other industry players and academics to explore new ways to stabilise the transmission system as energy becomes greener.

The long-term project will assist with the development of new commercial services for rapid frequency response - the first level of back-up for dealing with differences in supply and demand - across the energy market.

Dr Alastair Martin Founder and Chief Strategy Officer at Flexitricity, explained: “With energy becoming increasingly decentralised and greener, it is crucial that industry players work together to help the grid evolve as we shape the future of UK energy. The new landscape brings with it a range of opportunities for energy users to fully maximise their assets to not only generate revenue, but contribute to the creation of a more flexible, secure and fairer system.”

Lilian Macleod, EFCC Project Manager from National Grid, said: “The EFCC project will provide greater visibility of the grid system performance by using real time data. By working together with industry partners we can lead the transition to a new energy future. Not only will this help to deliver greater value to consumers by running the system more efficiently, it will also evolve and future proof the grid.”

GE Power, the partner behind the new monitoring and control system added: “We are excited to be part of the low carbon transformation of the GB grid, and to contribute to innovative solutions to remove barriers to a high penetration of renewable energy. Through the EFCC project, we are demonstrating a flexible approach to rapid frequency response so that a wide range of diverse technologies can participate in managing the frequency. The control system combines the responses to provide the grid with a fast and highly stable frequency control response. Applying our knowledge of system stability and experience with wide area control technology, we have been able to work with the EFCC consortium to demonstrate a control approach that can derive value from the various diverse technologies represented.”
