Pretoria wind and solar energy storage power generation prices

How do wind and solar power plants affect electricity market prices?

Wind and solar plants have near-zero marginal costs since they are weather-driven without inherent energy storage. Due to this property, these plants will be dispatched first, and they push more expensive power plants out of the market. Consequently, electricity market prices fall. system, as illustrated in Figure 2. If the supply curve is

How do wind and solar power prices change?

Since wind and solar power have no fuel cost, they push the price down by replacing more expensive fuel-consuming power plants. As wind and solar gradually become the primary power supply sources, market prices will drop on average, but price variations are likely to increase.

What happens if more wind and solar generation is available?

If there is more wind and solar generation available than needed by the consumers, prices will drop to near zero or even below, as generation must be curtailed to ensure balance in the power system (see Balancing fact sheet). In the long term, the impact is smaller than commonly expected.
