Polish Power Prices Turns Negative for Some as Renewables Boom

Polish power prices turned negative for some customers on two consecutive days as bright, windy weather sparked a surge in renewable electricity supplies that overwhelmed demand.

Market prices used to calculate settlements for renewable household installations fell below zero for several hours on both days this past weekend, according to data from Polish grid operator PSE. The lowest price point was touched Monday at minus 791.32 zloty (minus $214) per megawatt-hour and remained in negative territory for roughly 10 hours.
