Background: the grid under pressure

With around 30 Gigawatts of older fossil fuel and nuclear generation due to be de-commissioned by 2025, the UK is marching towards an energy capacity ‘gap’. The ‘capacity margin’, the buffer between peak demand and supply, has tightened, and the National Grid is being forced to take measures to secure additional capacity.

The commercial energy storage opportunity

Cost effective energy storage has arrived, bringing businesses the opportunity to:

  • Store electricity from renewable sources such as solar panels: if you have a solar system, store excess solar for later use – time shift rather than export it to the grid;
  • Reduce peak electricity costs by reducing ‘time-of-use’ surcharges such as TRIAD charges (TNUoS) and DUoS;
  • Earn income by providing support services such as frequency regulation, balancing services and capacity market payments to the National Grid;
  • Install a reliable commercial UPS battery back-up (replacing environmentally unfriendly diesel generators);
  • Avoid the need for costly grid upgrades e.g. to support EV charger roll-out;

Electric Vehicle Charging

All new cars sold by 2030 must be electric

A ban on the sale of new petrol and diesel cars has been brought forward to 2030. This inevitably poses the question around EV charging and the benefit of battery storage aligned with a solar rooftop installation.

There is no clear view at the moment of the number of charging points that are needed to deal with extra demand expected by 2030.

According to the RAC website – “What we can say for sure is that as of November 2020, a driver is never more than 25 miles away from a rapid chargepoint anywhere along England’s motorways and major A roads.1 That’s well within the range of even the most limited EVs today.

The latest figures show there are more than 20,000 charging devices in the UK (Nov. 2020).2”

Convenience will be key and the more charging points readily available across conveniently accessible commercial properties the better. Not only for employees but also for the public, potentially generating a return for businesses.
