kapasiteettimarkkinat

Kapasiteettimarkkinat, literally "capacity markets", refer to organized markets where participants can buy and sell electricity generation capacity. These markets are used to balance electricity supply and demand in real-time and to ensure that there is enough generation capacity available to meet peak demand periods.

Kapasiteettimarkkinat are typically used in power systems with a high proportion of intermittent renewable energy sources, such as wind and solar power. These sources can be difficult to predict and may not always be available when they are needed, so capacity markets provide a mechanism for buyers and sellers to hedge against this uncertainty.

In a capacity market, generators bid into a market to offer their available generation capacity, and buyers bid to purchase capacity to meet their needs. The price is determined by the bid of the marginal generator, which is the generator whose bid is just high enough to meet demand. Capacity markets can be used to secure generation capacity during peak periods, to provide a financial incentive for generators to build new capacity, and to increase the overall efficiency of the power system.

Some of the key characteristics of kapasiteettimarkkinat include the use of nodal pricing, where transactions take place on a specific node in the grid, and the involvement of independent system operators to manage the market and ensure its stability. Capacity markets are an increasingly important tool for power systems to manage the integration of intermittent renewable energy sources and to ensure that there is sufficient generation capacity to meet demand.
