peakkrav

Peakkrav is a term used in the Nordic electricity market, particularly in Sweden, to refer to the maximum electricity demand or load that a system operator or supplier expects to meet during a specific period. The word literally translates to “peak requirement.” It is a key metric in the planning and operation of national and transnational power systems, influencing the procurement of generation capacity, the activation of reserve power plants, and the design of pricing mechanisms.

In practice, peakkrav is derived from demand forecasts that incorporate historical consumption patterns, weather data, and scheduled industrial activity. System operators, such as Svenska Kraftnät in Sweden, use these forecasts to trigger security margin requirements, ensuring that additional generation or load‑management resources are available to maintain system reliability. The peakkrav figure is also communicated to market participants, who bid into day‑ahead and balancing markets to meet expected peak loads.

Peakkrav is closely related to concepts such as reserve margin, loss of load expectation, and the Maximum Demand. It serves as a benchmark for regulatory authorities to evaluate the adequacy of national generation portfolios, particularly as renewable penetration increases. A low peakkrav relative to available capacity signals a risk of grid instability, whereas a high peakkrav may indicate underinvestment in generation or insufficient demand-response programs.

Regulatory frameworks in Sweden and neighboring countries require periodic verification of peakkrav forecasts against actual peak demand, and penalties may be imposed if the system fails to meet obligations during high‑load periods. This approach helps maintain the “security of supply” standard set by the European Network of Transmission System Operators for Electricity (ENTSO-E).
