Curtailment of Electricity

What is Curtailment of Electricity?Definition

In the energy sector, the term “curtailment” refers to the reduction of power production (“generation curtailment”) or – less frequently - power consumption (“load curtailment”) when there is too much electricity in the grid (generation curtailment) or when there is not enough power in the grid (load curtailment). Curtailment aims at lessening the stress on the grid at a given moment of the day. Most commonly, curtailment is associated with the reduction of infeed from renewable energy sources.

Day-Ahead Trading of Electricity

What is Day-Ahead Trading of Electricity?Definition

Day-ahead trading of electricity refers to the buying and selling of electricity on the day before the actual production and delivery. Day-ahead trading either takes place on the spot market of the respective power exchange (often called day ahead market or day ahead auction) or through bilateral contracts between two parties - usually power trading companies - outside of the power exchange in over the counter (OTC) deals.

How VPPs integrate renewables into the energy system

Wed., April 29 2020, 9:30 a.m. (UTC+2)

Higher shares of renewables in electricity mix require perfect coordination of their energy generation to provide a cost-efficient and secure electricity supply and guarantee a stable grid. Virtual Power Plants (VPPs) allow to aggregate thousands of electricity producers, consumers and storage units and to control them according to signals from the wholesale market and system operators.

Winter belongs to Wind Power

For weeks now, Germany and its European neighbors have had a peak season for wind power. The winter storms Sabine (also known as Ciara or Elsa), Victoria (known as Dennis in UK) and Yulia brought new records – most recently the unprecedented peak value of 46.2 gigawatts (GW). Renewables accounted for 69 percent of net electricity production in the third week of February, with wind accounting for 55 percent. Never before has so much wind power been fed into the German power grid. Are these figures the result of extreme weather conditions, which simply brought us an extraordinary number of storms this winter, or is there a general trend here? And how does the German energy system actually cope with these record values?
