Wartsila commissioned two complete power plants with a total output of 250 MW for Elering AS, the Estonian transmission system operator. The total value of the order is EUR 129 million. The power plants will provide dynamic generation capacity to meet sudden and unexpected drops in the electricity supply.

The power plants are based on Wartsila 20V34DF engines, which operate primarily on natural gas but with the option to switch to light fuel oil as a back-up fuel. The requirement for these plants is that they have to be able to compensate for lost generating capacity in no more than 15 minutes in the event of a plant shut down.
