Project description

The Pfreimd power plant group consists of three storage lakes, one run-of-river and two pumped storage power plants. In the context of the energy transition, it is considered an essential component in the renewable energy mix. Due to its black start capability on the one hand, and its highly accurate and over-fast deployment capability for grid stability on the other hand, it contributes as an indispensable element to the turn towards green energy in Germany.

The operator of the power plant group, engie Deutschland GmbH, is investing double-digit millions in each of the two major overhauls in 2020/2021 to modernize the main structural, mechanical, electrical and I&C components.

INP Deutschland GmbH is contributing to the success of the site overhaul for continued secure operation over the next 20 years through the extensive services listed below.
