Pearlstone

Pearlstone Energy is a demand side response (DSR) aggregator operating in the UK. The company specializes in providing energy management solutions to commercial and industrial facilities, enabling them to participate in National Grid's flexibility initiatives. Pearlstone's cloud-based solution manages customers' energy consumption, allowing them to adjust their electricity usage based on supply and demand. By reducing energy consumption by 10-20% during peak times for one to two hours or increasing power via generators, businesses can generate new revenue streams by selling their energy back to the grid. This approach helps facilities avoid high network demand charges during periods of grid strain and rewards participants with potential cost savings year-round.

In September 2022, Pearlstone Energy partnered with Generac Grid Services to leverage their Concerto software platform. This collaboration enables Pearlstone to reduce demand at each customer facility during system peaks, typically during the coldest days of the year or when there is a need for equilibrium in the system. The partnership aims to unlock value from commercial and industrial facilities' flexible capacity and improve the stability and sustainability of the UK power grid.

Pearlstone's offerings contribute to the UK's demand side flexibility goals and net-zero emission targets. The company's services are particularly relevant as the UK faces challenges in transitioning from fossil fuel generation to renewable energy sources. As of 2022, the current demand side response level in the UK was less than 2GW, but projections suggested it could reach 6GW by 2030 and 16GW by 2050. Pearlstone's typical demand response availability averages 200kW per facility, primarily from HVAC and air handling equipment, with potential annual values of approximately GBP 8,000 per facility.
