Topic: 6. 5 Energy System Integration
Summary / Abstract: Solar electricity has been gaining market share and is becoming a significant player on the electricity market. We investigated the long-term business case effects for various utility scale PV configurations in their interaction with other developments in the electricity market, including integration of battery storage and flexible assets, such as electrolysers. For both wind and solar energy, the cost to produce one more unit (of energy) is very low, near-zero and therefore will deliver electricity at any (positive) price on the market. These so-called marginal costs are much higher for fuel-based power plants. They also are rather variable, literally, by nature. We have looked at the impact of increased PV capacity at near-zero marginal cost in the context of the Dutch electricity market. We will show that significant deployment of utility scale PV parks will result in significantly lower electricity prices. We will also highlight the stabilising role of energy flexibility on the forecasted electricity price, e.g. by a larger deployment of hydrogen electrolysers on the demand side.
