Three plants in the Krasnoyarsk Region, Siberia, Krasnoyarsk CHP-2 (465 MWe), Nazarovskaya GRES (1120 MWe) and Berezovskaya GRES 1 (1600 MWe), were selected for a pre-feasibility study. The study included energy efficiency audits as well as environmental and social audits.
At Krasnoyarsk CHP-2, three energy efficiency measures were recommended implemented resulting in a total emission reduction of 70 ktons CO2 per year where 39 ktons were considered eligible for credits in a Joint Implementation Project. The measures would be profitable to implement at a CO2 price of approx. 6.5 USD/ton.The largest potential for energy efficiency in the city of Krasnoyarsk was, however, estimated by upgrading the city’s district heating network and consumer installations coordinated with the two other productions units CHP-1 (1085 MWth) and CHP-3 (365 MWth). The magnitude of the CO2 reductions is 400 ktons per year.At Nazarovskaya GRES, measures to increase energy efficiency would reduce CO2 emissions by 385 ktons per year. It would be profitable to implement the measures at a CO2 price of approx. 3 USD/ton. However, the plant is beyond its design lifetime.Recommended measures at Berozovskaya GRES would reduce CO2 emissions by approx. 185 ktons per year and hereof approx. 95 ktons are deemed additional in a JI projects. The profitability of implementing the measures is acceptable at a CO2 price of approx. 5.5 USD/ton.
