In June 2023, Sandbrook launched Voltwise Power (Voltwise), a newly formed developer, owner, and operator of utility-scale battery energy storage systems (BESS). Voltwise is initially focusing on the UK and Germany, with the intention of expanding further across geographies in Europe and will target BESS projects strategically located near large power demand centers, or at places where the grid faces heightened congestion, price volatility, or fragility. The management team has decades of experience building and developing successful businesses across the energy sector globally, with a particular focus on power generation, commercialization, risk management, and BESS solutions.
The investment in Voltwise aligns with our belief that Europe will require a significant buildout of utility-scale battery storage in the coming decade to preserve the reliability of its power supply. The rise in intermittent generation (wind and solar) combined with the retirement of traditional baseload resources, such as coal, is placing increasing stress on the electric grid’s ability to sustain all-hours reliable supply. Furthermore, European regulators and markets are developing new commercial and legal frameworks to stimulate the deployment of battery storage as the flexibility offered by BESS will make material and measurable contributions to the decarbonization of the power grid.
