The increase in renewable energies causes drops in the wholesale price that are not reflected in the electricity bill
The growth of renewable energies in Spain and Europe is causing very low and even negative prices in the wholesale electricity market, especially on days with high solar and wind production and reduced demand. This excess supply causes the price of a megawatt hour to plummet at certain times, an increasingly common situation in the electricity system.
However, this drop does not directly translate into a cheaper bill for households. The electricity bill includes other fixed costs such as tolls, charges and taxes that reduce the impact of these decreases, so the consumer does not fully perceive the reduction in prices that does occur in the wholesale market.
Furthermore, the electrical system still has difficulties managing this surplus of energy. The lack of sufficient storage and more flexible networks limits the use of these low prices, which is why experts point to the need to invest in batteries and infrastructure modernization to better transfer savings to the consumer.
