The base load (also baseload) is the minimum level of demand on an over a span of time, for example, one week. This demand can be met by unvarying power plants or, depending on which approach has the best mix of cost, availability and reliability in any particular market. The remainder of demand, varying throughout a day, is met by

Energy storage mitigates renewable energy curtailment by absorbing excess electricity generated during periods of high renewable output and low demand or grid constraints, then releasing it when demand is higher or grid capacity is available. . As the penetration of variable renewable energy increases, curtailment of solar PV generation will only increase. Since curtailment will almost always be cheaper than investing in new transmission capacity or new grid-scale storage, curtailed energy should be rewarded, so that PV investment. . curtailment is emerging as a common challenge facing a growing number of power systems. At its core, curtailment is a symptom of an insuficiently flexible power system. This reduces the need to limit renewable generation. .
