Polish grid asks utilities to increase capacity during heatwave

The Polish grid operator, PSE, has asked power producers to meet their 'capacity obligations' on Tuesday evening in order to increase generation reserves. This is because the country is currently experiencing a heatwave with low wind farm production.

This call is a redressal measure that the grid can take when the surplus of?generation capacity above projected demand falls below?the safe level. The PSE call is scheduled for Tuesday, from 6 pm to 9 pm local time (0400 GMT to 700 GMT).

Maciej Wapinski, spokesperson for the PSE, said that "the surplus projected of 600 megawatts is not enough to meet demand."

Although Poland's abundant?solar? capacity doubles the power demand at weekends, it can be difficult to supply the system on hot weekday evenings. Solar output is reduced and the?demand for electricity remains high due to air conditioning use. Low wind output makes the problem worse.
