Battery storage project a ‘blueprint’ for EV charging infrastructure globally

Tesla South Mimms Supercharger and PowerPack

Pairing batteries with EV charging stations can help to align sustainable transport and energy needs for the future.

At South Mimms Welcome Break Motorway Services, we have installed a 250kW/500kWh Powerpack alongside one of Tesla’s largest and busiest UK charging locations. The Supercharger site can charge up to 12 cars at one time, and since popular charging periods often coincide with peak periods of grid demand – between 4pm and 7pm, when electricity prices are at their highest – flexible solutions are needed to ease the strain on local grids and control electricity costs.

Integrating a Powerpack at the location has meant that during peak periods, vehicles can charge from Powerpack instead of drawing power from the grid. Throughout the remainder of the day, the Powerpack system charges from and discharges to the grid, providing a Firm Frequency Response (FFR) service to National Grid and earning revenue for balancing grid electricity supply and demand on a second-by-second basis.

Open Energi own and operate the Powerpack, which is part of our portfolio of assets that help maintain the frequency of the grid. Combining batteries and electric vehicles makes vehicle charging part of the solution to integrating more renewables without affecting drivers, unlocking vital flexibility to help build a smarter, more sustainable system.

The project at South Mimms Welcome Break Motorway Services provides a blueprint for the development of electric vehicle charging infrastructure globally. Moreover, by reducing National Grid’s reliance on fossil fuelled power stations as a means of balancing electricity supply and demand, the Powerpack helps to reduce UK CO2 emissions by approximately 1,138 tonnes per year.

Ashden Awards 2016: Open Energi Case Study

To keep the lights on, National Grid has to keep electricity demand and supply exactly in balance, and when faults occur a rapid response is needed – within two seconds! Traditionally this was provided by gas and coal power plants running below full power, so they can adjust output quickly, but this is inefficient, expensive and increases CO2 emissions. Open Energi has developed an alternative – cutting-edge software which can automatically switch energy-hungry equipment on or off when required, without disrupting business operations.

Large energy users like water companies identify which items of equipment are not time-sensitive in their operation and this equipment can then increase or decrease its consumption within agreed parameters to provide a rapid response service to National Grid.

Green Gown Awards recognise University of East Anglia’s innovative approach to energy management

University of East Anglia and Open Energi were Highly Commended for their entry in the Technical Innovation for Sustainability category at the 2014 Green Gown Awards.

 

UEA was the first university to install Dynamic Demand across its campus, helping to keep the lights on and boosting its credentials as one of the most sustainable universities in the country.

Air handling units (AHUs) across its estate have been equipped with this unique form of Demand Response and the AHUs are now adjusting their energy consumption instantaneously to help National Grid balance electricity supply and demand in real-time.

What it means to win… “UEA has a top-rated School of Environmental Sciences and we are committed to replicating this success in the sustainability of our campus. Adopting more intelligent ways of managing our electricity demand supports this goal and we are thrilled to win a Green Gown award for our work with Open Energi.“

Professor Edward Acton, Vice-Chancellor

 

What the judges said: An interesting application of technology into the HE sector, where the complexity of power demands across a campus can be used to balance the power system. Clear applicability to other areas, and replicable elsewhere. The “invisibility” of the technological fix is also attractive.

Dynamic Demand wins Innovation of the Year Awards

Business Green Leaders Awards

Open Energi is proud to have been awarded Innovation of the Year at the 2014 BusinessGreen Leaders Awards for its Dynamic Demand technology, a unique form of Demand Response which helps National Grid to balance electricity supply and demand on a second-by-second basis.

Now in their fourth year, the BusinessGreen Leaders Awards celebrate the leading businesses, executives, entrepreneurs, investors, and campaigners from across the green economy, highlighting how these pioneers are driving the emergence of innovative and sustainable new business models and technologies. The Awards were extremely competitive with over 260 entries whittled down to 130 shortlisted entries.

“Everyone at Open Energi is delighted and proud that Dynamic Demand has been recognised by the prestigious BusinessGreen Leaders Awards,” commented Open Energi Commercial Director, Ged Holmes. “Balancing supply and demand is vital to the operation and security of the UK electricity system and Dynamic Demand has a vital role to play in delivering clean, secure and affordable energy in the years to come.”
