Ukraine's New Grid Rules Threaten Solar Power Sales and Profitability

Ukrainian Solar Energy Association Raises Alarm

According to Главком: The Ukrainian Solar Energy Association has expressed serious concerns over the implementation of a 'pre-dispatch' mechanism for renewable energy. This system allows the grid operator to determine in advance which power plants should operate and at what capacity to ensure grid stability. While a necessary step under martial law and the current emergency state of the energy system, this mechanism introduces significant new risks for solar power generation. This development comes as Ukraine's energy sector works to maintain operations amidst ongoing conflict.

Financial Risks for Solar Plants

Solar power stations can now be forcibly restricted from feeding their generated power into the grid even before it is sold, leading to a situation of 'under-produced' energy. This could severely impact the financial viability of renewable energy projects, especially given the lack of compensation for these losses. As Vladyslav Sokolovskyi, Chairman of the Board of the Ukrainian Solar Energy Association, stated:

“This step is not very positive for solar generation, as the operator can prioritize other generation sources, leading to restrictions on solar power plant capacities.”

To mitigate these risks, the Association advocates for the integration of energy storage systems. Vladyslav Sokolovskyi emphasized that more actively incorporating storage installations into solar plant operations could be a solution. When plants are disconnected from the grid by dispatcher command, the ability to channel generated electricity into their own storage units could reduce the negative impacts of curtailment. Therefore, dispatcher decisions need to be more flexible and balanced.

Additionally, the Ukrainian Wind Energy Association (UWEA) has also voiced concerns about the risks to electricity producers from implementing the pre-dispatch mechanism without cost compensation. This indicates broad apprehension across the renewable energy sector regarding the new operating conditions in Ukraine.

The introduction of the pre-dispatch mechanism is driven by the need to ensure grid stability during wartime, but it simultaneously jeopardizes the financial stability of renewable energy projects. Specifically, restricting solar plant capacities can result in under-produced energy, which in turn negatively affects investors and industry development. Integrating energy storage could be a crucial step toward mitigating these risks and enhancing system flexibility.
