Electricity generation in Ukraine's integrated power grids in 2015 fell by 13.6%, or 24.380 billion kWh, year-over-year, to 157.165 billion kWh, the Energy and Coal Industry Ministry has told Interfax-Ukraine.

Nuclear power plants (NPPs) reduced electricity output by 0.9%, to 87.628 billion kWh. In particular, power production at Zaporizhia NPP amounted to 39.305 billion kWh (a 0.8% decline from 2014), Yuzhnoukrainsk NPP generated 15.935 billion kWh (an 18.8% fall), Rivne NPP 18.932 billion kWh (a 3.8% rise), Khmelnytsky NPP 13.455 billion kWh (+23.3% rise).

Thermal power plants (TPP) and combined heat and power plants (CHPP) reduced production by 26.4%, to 55.205 billion kWh. In particular, TPP generating companies cut production by 27.73%, to 49.502 billion kWh, CHPPs saw a 12.8% decline in output, to 5.703 billion kWh.

Hydroelectric power plants in 2015 reduced production by 25.1%, to 6.809 billion kWh, municipal CHPPs by 21.2%, to 6.141 billion kWh.

Electricity production by non-conventional sources (wind farms, solar stations, biomass) decreased by 11%, to 1.482 billion kWh.

The share of NPPs in electricity generation was 55.72% (48.58% in 2014), thermal power plants and CHPPs 35.1% (41.23%), hydroelectric power plants 4.3% (5%), municipal CHPPs and block stations 3.9% (4.28%), alternative sources 0.94% (0.92%).

In December 2015, electricity generation in Ukraine shrank by 12.6% year-over-year, to 14.578 kWh.

NPPs, TPPs and combined heat and power plants of the ministry increased heating supplies by 3.1% in 2015 from 2014, to 22.449 million gigacalories.
