We developed the preliminary design of a heat storage system integrated into Riga CHP-2 plant in Latvia. The CHP plant consists of two CCGT units and five hot-water boilers and supplies heat into the district heating system of Riga.

BFS Industry activities:

• Optimization of the storage capacity and charging/discharging power in three variants
• Elaboration of preliminary design
• Calculation of expected revenues, CAPEX and OPEX

Execution date: 10/2017 - 01/2018
