National Energy Company Ukrenergo on January 7, 2020 due to abnormally warm temperatures for this period of the year restricted loading generation of six large wind farms by 384 MW and eight solar power plants (SPP) by 545 MW in the period from 12:09 through 13:00, the company’s press service has reported.
Ukrenergo said that on that day, the average daily air temperature was -2.4°С, which is 4°С higher than the one on January 7 last year. Accordingly, consumption on January 7, 2020, decreased by 47.6 million kWh or 10.6% compared to the same period of the previous year (394 million kWh versus 441 million kWh).
Prior to this, all applications of balancing market players were used, electricity imports to the Integrated Power System (IPS) of Ukraine from Belarus and the Russian Federation were limited to zero, and the thermal power plants (TPP) generation was also limited by 1,350 MW.
Besides, at the moment of a sharp leap in the renewable energy generation from 12:09 to 13:00, there has already been no possibility to switch to the pumping mode the hydroelectric generators of pumped storage power plants (PSPP) since at that moment their reservoirs have already been filled.
At the same time, it is worth noting that due to the short-term nature of the balance deviations nuclear power plants (NPP) loading was not restricted.
“Therefore, in order to balance the power system and ensure its operational safety, NPC Ukrenergo dispatchers had to restrict the loading of powerful wind farms and SPPs,” the company said.
After that, from 13:00 to 13:46, all wind farms and SPP generation restrictions were rescinded.
Ukraine in June 2019 increased electricity generation from renewable energy sources by 2.8 times (by 378.3 million kWh) compared to June 2018, to 585 million kWh.
According to data from the Ministry of Energy and Coal Industry, available to Interfax-Ukraine, production of electricity from renewable energy sources in January-June 2019 increased by 1.9 times compared to the same period last year, to 2.372 billion kWh.
The share of renewable energy in the structure of electricity production in June 2019 reached 5% against 1.8% in June 2018, while the share of renewable energy in the first half of this year was 3% against 1.5% in January-June 2018.
As reported, as of the end of the first half of the year, the installed capacity of renewable energy facilities reached 3,634 MW, in particular that of solar plants some 2,640 MW, wind plants 776.6 MW, biomass plants 51.3 MW, and biogas stations some 66.4 MW.
Electricity generation in the united energy system of Ukraine in 2018 increased by 2.5% compared to 2017, to 159.351 billion kWh, the Ministry of Energy and Coal Industry has told Interfax-Ukraine.
At that time, nuclear power plants (NPP) in the period reduced electricity generation by 1.4%, to 84.398 billion kWh, in particular, electricity generation at Zaporizhia NPP amounted to 35.924 billion kWh (4.1% more than in 2017), Yuzhnoukrainsk NPP to 18.329 billion kWh (2.4% more), Rivne NPP to 17.55 billion kWh (11.3% less), and Khmelnytsky NPP to 12.595 billion kWh (down by 5.9%).
Thermal power plants (TPP), as well as combined heat and power plants (CHPP) and cogeneration plants increased output by 5.3%, to 58.808 billion kWh. In particular, the generating companies of TPPs increased production by 6.3%, to 47.792 billion kWh, while CHPP and cogeneration plants by 1.2%, to 11.016 billion kWh.
Hydro power plants and hydroelectric pumped storage power plants raised production in 2018 by 13.6%, to 12.008 billion kWh, while block stations reduced by 1.9%, to 1.504 billion kWh.
Electricity production by alternative sources (wind power plants, solar plants, and biomass) in 2018 rose by 38.8%, to 2.633 billion kWh.
The share of NPPs in the structure of electricity generation was 53% (55.1% in 2017), that of TPP, CHPP and cogeneration plants – 36.9% (35.9%), hydro power plants and hydroelectric pumped storage power plants – 7.5% (6.8%), block stations – 0.9% (1%) and alternative sources – 1.7% (1.2%).
Electricity generation in Ukraine’s power grid in December 2018 rose by 7.2% year-over-year, to 15.871 billion kWh.
Heat generation last year rose by 0.3%, to 22.032 million gigacalories.
