The NEURC has approved the Generation Adequacy Report developed by NPC Ukrenergo. Since the first draft, more specifically since 2017, it is the first approval of this strategic document. The Report is of recommendation nature and is based on the study of many development scenarios for the Ukrainian energy industry and economy.
“One of the major problems demanding the most urgent solution is the improvement of the Ukrainian power system flexibility in conditions of fast-growing volumes of generation with RES. It is forecasted that in late 2020 the capacity of alternative energy will grow up to at least 7.4 GW, and in 2030 it will reach 11.2 GW. That is why as early as in 2021 it is planned to build 2 GW of new high-maneuver capacities having the control range of at least 80 per cent of the installed capacity and capable of supporting the startup and stoppage up to 8 times a day with the time to reach the rated capacity not exceeding 15 minutes. Existing generating capacities do not have such potential. In absence of primary control reserves, at least 200 MW of electricity accumulation systems should be introduced additionally before 2021 to support frequency maintenance reserves”, commented on key findings of the Report Vitalii Zaichenko, Director for Management of the IPS of Ukraine – Chief Dispatcher.
Additionally, the target scenario of the Report envisages the following actions:
- assurance of at least 12 GW of permanently available operating capacity of TPPs by 2030 through their renovation and reduction of harmful emissions
- availability of 2 gas-oil units of 300 MW each as an additional reserve for the power system
- maintenance of the NPP installed capacity at the existing level (13.8 GW) and launching the actions to ensure the timely replacement of the NPP power units which will be decommissioned
- implementation of commissioning plans for HPSPP capacities (if timely commissioning is not achieved, it will be necessary to introduce energy accumulation systems to replace such capacities)
- prevention of electricity production surplus in certain periods is possible either via a short-term limitation of RES capacity or a long-term (more than one day) limitation of NPP capacity (there is a low likelihood that surplus production can be sold by export because adjacent power systems have a very low demand too during this time).
The Report also outlines a number of first-priority actions which if implemented will ensure the balance reliability of the power system and the energy security of the country for the near-term period:
- ensure pricing in the balancing market and ancillary services market in such a way so that there is no reduction in availability of necessary balancing capacities
- envisage in the laws and regulations the tools and the algorithm to limit the NPP capacity to meet the operating conditions of the power system
- introduce the RES responsibility for non-balances
- amend the Transmission System Code and the Market Rules to ensure cost recovery of energy accumulation systems (NPP, HPSPP, etc.) to meet the needs of the IPS of Ukraine during one day
- when establishing quotas on RES support, oblige investors to ensure both the high-maneuver generation or Energy Storage systems in the volume of about 20 per cent of the installed capacity of the plants
- volumes of annual quotas on RES support should not exceed the capabilities of the power system of Ukraine in terms of their integration into the power system without the power output limitation.
Implementation of these and the majority of other recommendations of the Report is within the purview of executive and legislative bodies, as well as actual electricity producers and investors.
The Report is developed in line with the Law of Ukraine “On Electricity Market”, the Transmission System Code, forecast electricity balances, the Energy Strategy for the period to 2035 and other strategic documents, and takes into account recommendations and comments issued by the NEURC, ENTSO-E, market participants, and the public.
