In this episode, we spoke to Randall Bowen, Managing Director of Voltalis UK – the biggest European demand-side flexibility operator. Of particular interest to the UK's energy strategy is its GW-scale fleet of storage heaters, which are not currently responsive to spot market electricity prices. When the relevant authorities give their stamp of approval for Voltalis to install its devices, they will become part of grid flexibility – a crucial step given the UK’s struggles with other types of grid development.

Voltalis is a French company with 1,500,000 integrated appliances across more than 200,000 residential and commercial buildings in Europe, now expanding into the UK.
