NEURC Approved Transmission System Development Plan until 2029, with Investments of UAH 68 billion
The National Energy and Utilities Regulatory Commission approved a draft plan for the development of the Transmission System until 2029, with an investment volume of UAH 68,715 billion, the plan provides for the commissioning of lines and substations for the delivery of capacities of Zaporizhzhya NPP, 500 kV substations Kreminska and Vinnytsya, as well as the networks required for the integration into ENTSO-E.
This decision was made on March 13 at a meeting of the regulator.
“The development of the network should solve the problem of “closed” capacity of Zaporizhzhya NPP. In April-May 2020 we plan to put into operation the 750 kV Zaporiznznya NPP - Kakhovskaya substation. That will enable normal operation of the nuclear power plant and its power output," said Ukrenergo's Director for Grid Operation and Development Oleksii Brekht, presenting the draft plan.
Brekht also commented on the construction process of the Kreminskaya substation. “On the next Monday (March 16 – ed.) we will begin testing and apply voltage to the 220 kV switchgear with the subsequent commissioning of all other equipment. On May 20, this facility should be put into operation,” he said.
According to him, in 2022 Ukrenergo plans to complete the construction of networks, so that the fourth unit of the Dnister HPSPP gives out its capacity. As part of the integration of the Integrated Power System of Ukraine into ENTSO-E, the reconstruction of the lines on the border with Slovakia e. i. Mukachevo - Velki Kapushany is envisaged.
In accordance with the Transmission System Development Plan, it is planned to build new transmission lines: with a voltage of 750 kV - 611 km; 500 kV - 61 km; 400 kV - 55 km; 330 kV - 2 259 km; 220 kV - 90 km. The overall transformer capacity is planned to increase by 15.5% (12,451 MVA) to 92,790 MVA, as well as reconstruction of the existing 79 substations, 1537 km of 330 kV transmission lines, 10 km of 220kV transmission lines. The Development Plan also includes information that as of 2019, 17.3% of substation equipment and 66.7% of transmission lines have been in operation for more than 40 years.
As a result, there are an increase in electricity losses in the transmission system; limitation of the possibility of preventing technological disruption; violation of the normal and reliable operation of the equipment of the transmission system and the IPS of Ukraine as a whole.
A general increase in demand over the next 10 years is expected to reach 11,6%.
