Sandbox Project Bags Two Major Industry Awards

November 2023

We are delighted to have won in quick succession both the award for Net Zero initiative – Heating and Cooling at The Energy Awards, and the Smart Systems and Flexibility Project of the Year at The Net Zero Edie Awards for our Sandbox project.

Alongside Dimplex and Midland Heart Housing Association, we conducted trials under Ofgem’s regulation innovation sandbox programme to offer flexibility services into the Balancing Mechanism, the electricity system operator's (ESO's) primary tool used for balancing supply and demand on Britain's electricity transmission network. This was the first-time home heating devices have been used for such a service, paving a much more consumer-led, demand-side approach to energy flexibility in the UK.

This news coincides with the next stage of our partnership with Dimplex – the British Gas Dimplex Quantum Tariff. The tariff allows consumers to directly benefit from DSR with a reduced night-time rate compared to other E7 tariffs. With even more Dimplex storage heaters connected to our VPP, this provides the opportunity to build on the evidence and insight gained from the Sandbox trial and continue to grow our aggregation services.

I was delighted to collect this award on behalf of everyone that’s worked so hard to deliver a successful trial across this partnership. We’re cutting new paths in the energy markets for the benefit of our customers, and to have this recognised right at the launch of the tariff that this sandbox trial initiated is great for the future of DSR, and for everyone that will benefit from it as it grows.

The awards recognise our collective achievement to bring innovative nationally critical net zero technologies to the domestic environment and our tenants. DSR means that we have now installed smart storage heaters that can provide cleaner, more secure energy to our tenants in the form of heat and at no detriment to their comfort. We are also delighted that feedback from tenants will help shape the further roll-out of the technology and a new electricity tariff. Collaboration is a key element of our Carbon Reduction Plan and together we are showcasing how social housing can be retrofitted with low carbon energy, combining conventional approaches alongside new and innovative technologies.
