Kiisa ERPP I & II

Kiisa, Estonia

250 MW

Even in one of the smallest countries in the EU, managing the power grid is not easy. This is the task of Wärtsilä's customer Elering, the Estonian trans-mission system operator (TSO), who is responsi-ble of operating the Estonian electrical grid in a safe way. A constant, real-time balance between supply and demand is an abso-lute must to keep the grid running and without unbalancing the frequency. However, a TSO can only control one side of the equation. While the energy supply has to be carefully managed by the TSO, in order to meet the amount the country is consuming every minute, power consumption cannot be controlled. What happens if too many customers coinciden-tally decide to start using electricity at the same time, or one of the main power plants suffers an unexpected malfunction? A blackout.

Kiisa - Estonia

For us, the specific technology was not so relevant. We had end results that needed to be met, and Wärtsilä's engines simply offered an unrivalled solution.

THE CHALLENGE

Extremely fast ramp-up time to comply with grid requirements

Ability to restart the whole national grid in case of a total blackout

Extreme ambient conditions -80ºC variance between summer and winter temperatures

Minimising the need for on-site operating personnel

WÄRTSILÄ'S SOLUTION

Internal combustion engines with
the best ramp-up capability in the market (>100%min)

Blackout capability: no need for electricity to start-up

Internal combustion engines insensitive to extreme conditions

Fully automated operation,
no on-site personnel needed

BENEFIT

True stability for the grid, ability to
fill in immediately in case of failure

Safety and stability, the Kiisa plant can over the loss of the biggest generation unit of the country

All-year round reliability

Cost decrease, personnel focused
on key tasks and minimised price
for reserve power
