Abstract

The thermal energy storage (TES) system installation provides the optimization of energy source, energy supply security, flexibility of power plant operation and energy production. The aim of given research is feasibility analysis and evaluation of thermal energy storage system installation at Riga cogeneration heat power plant (CHPP) Nr. 2 with P_el = 832 MW and Q_th = 544 MW (cogeneration unit Nr. 1 and Nr. 2). The six modes were investigated: four for non-heating periods and two for heating periods. Different research methods were used: data statistic processing and analysis, forecasting, financial analysis, correlation and regression methods. Finally, the best mode was chosen with aim to increase of cogeneration unit efficiency during the summer period.
