State-owned enterprise Ukrenergo saw a 42% fall in net profit in 2017 (by UAH 1.264 billion) compared with 2016, to UAH 1.748 billion.
According to a company financial report, net revenue last year rose by 15.2% or UAH 1.09 billion, to UAH 8.264 billion, and gross profit grew by 17% or UAH 849.257 million, to UAH 5.838 billion.
As reported, national energy company Ukrenergo in 2017 increased transmission of electricity through the backbone power grids by 2.4% (by 2.616 billion kWh) compared to 2016, to 113.837 billion kWh. The cost of electricity transmission services rose by 13.7% in 2017 (by UAH 965.217 million), to UAH 8.022 billion.
Ukrenergo operates trunk and interstate power grids, as well as performs the centralized dispatching of the united energy system in the country. The company is a state-owned enterprise, it is subordinate to the Ministry of Energy and Coal Industry, but by the end of 2018 the company is to be reorganized into a private joint-stock company.
National energy company Ukrenergo believes that in the conditions of rampant development of renewable energy, highly maneuverable balancing facilities (battery and gas reciprocating power plants) with a capacity of 2.5 GW should be built in Ukraine before 2025, Ukrenergo Head Vsevolod Kovalchuk said at the presentation of the respective study in Kyiv on Tuesday.
“Quick maneuverable balancing facilities should cover 30% of the installed capacity of facilities using renewable energy. Based on the forecasts of how the total capacity of solar power plants and wind farms will increase, by 2025 we need to build maneuverable facilities with a capacity of 2.5 GW – energy storage facilities with lithium batteries and gas reciprocating plants,” he said.
Kovalchuk said that the cost of building these facilities is about UAH 55 billion.
The head of Ukrenergo said that if Ukraine does not build highly maneuverable facilities, then with an increase in the share of renewable energy, it will have to limit production of nuclear power plants (operating in the basic mode) and increase the share of coal-burning thermal power plants (TTPs capable of maneuvering). This will raise the total cost of electricity generated in the country by 57.7%.
Another alternative scenario is to limit the operation of solar power plants and wind farms in the peak periods. This will cost the country even more, as it will have to pay for both operation of nuclear power plants and TPPs, as well as compensate for under-generated electricity of solar power plants and wind farms. In this scenario, the total cost of electricity generated in the country will increase by 99%.
“Out of the three possible scenarios, the construction of highly maneuverable balancing facilities leads to the least increase in the cost of electricity – by 48.7%. The investment of UAH 55 billion in their construction will save UAH 65 billion in comparison with the scenario of limiting the operation of renewable energy,” the head of Ukrenergo said.
The head of the company said that, in his opinion, the construction of energy storage facilities with lithium batteries should be stimulated either by introducing a special tariff (following the example of ‘green’ energy) or through the mechanism of auctions.
“We will initiate the introduction of a feed-in tariff, or other mechanisms that would make it possible to make the profitability of these highly maneuverable facilities no lower than for facilities consuming renewable energy,” Kovalchuk said.
The head of the company said that a pilot project can be organized through Ukrenergo, when the Ukrainian power grid operator itself holds an auction for the construction of energy storage facilities.
At the same time, he said that it would be impossible to delay the solution of the problem. The first 500 MW of highly maneuverable facilities should begin to operate in 2020.
