RedT signs 700 MWh deal

7 August 2018

Energy storage specialist has signed an exclusive deal with Energy System Management GmbH (ESM) to deliver over 700 MWh of energy storage projects in Germany.

In a first phase, UK-based RedT will deliver two 40MWh grid-scale energy storage projects in Germany to provide supply Secondary Control Reserve (SCR) to the German and Austrian markets.

The two projects will use RedT’s Gen 3 tank units, based on proprietary vanadium redox flow technology. Construction could begin in 2019 if the project developers secure financial close, Red T said, adding that there are plans to roll out a further 690 MWh in the future.

Scott McGregor, CEO, redT energy commented: “These projects are a ground-breaking development, not only for redT but for European energy markets as a whole. We are very pleased to partner with ESM, and together we look forward to delivering these projects to market.

“This is a real long-term infrastructure application for energy storage – providing 4 hours of capacity to the grid and supporting the growth of renewables, which is what stationary energy storage is designed to do. We are pleased that economic models in the market now support this development.”

According to Red T, the projects represent the first time that flow machines will be used in Germany to provide SCR, a service typically provided by coal-fired power plants.

This service requires up to a 4 hour charge or discharge duration and is designed to maintain equilibrium on the electrical network between demand and supply. Providers of SCR in Germany are paid a fee based on their available power (MW) and energy (MWh) to charge or discharge to the grid when required.

The first phase projects are fully developed with planning approval and grid connections, RedT said.
