Spanish properties and corporations have already got a complete electrical energy storage capability of just about 1.9 gigawatt hours (GWh), in keeping with the newest information from the Spanish Photovoltaic Union (UNEF). Although the marketplace for home batteries and for business and the service sector continued to develop in 2023, it did so at a noticeably decrease fee than in 2022—that of the vitality disaster—: it added slightly below 0.5 new GWh, in comparison with practically 1.4 of the previous twelve months. The majority of those installations are linked to a self-consumption system, whose set up fee additionally fell sharply in 2023.

Unlike what is occurring with rooftop photo voltaic panels, the place corporations are displaying a lot larger vigor, the residential sector reached a 77% share of battery installations in 2023, in keeping with UNEF figures. The employers attribute the latest slowdown to the drop within the value of electrical energy in latest months, which “reduces the profitability of this type of installations” and to the top of support from European funds. Sector calculations, nevertheless, point out that round one in three new self-consumption installations have already got a battery put in to maximise financial savings.

“[El parón] We have noticed it in self-consumption and, now, in storage data, since the batteries are usually installed at the same time as the self-consumption installation,” explains the final director of the sector group, José Donoso. “Batteries are a key piece for the integration of renewables into the grid and decarbonization,” he provides whereas calling for “financing schemes that make this type of installations more competitive, such as VAT exemption or tax relief,” he claims.

Spain is a number of steps behind different giant markets. Above all, Germany, the place self-consumption has taken sturdy root lately. Especially because the vitality disaster. According to the newest information from the sector's employers in that nation, 1.2 of the three.7 million properties which have panels on the roof even have an related battery. In only one yr, 2022, the German nation added as many batteries as Spain in two: 2022 and 2023. This increase is, in flip, lowering the quantity of vitality they demand from the grid.

The sharp drop within the value at which surpluses from self-consumption installations are paid can be, nevertheless, a robust demand for individuals who have photo voltaic panels of their house to put in a battery with which to cowl nighttime wants. In latest instances, self-consumers adhering to the regulated market (additionally identified beneath the acronym PVPC) have seen the worth of their surpluses plummet throughout sunlight hours, through which they should compete with rising photovoltaic manufacturing. So a lot so, that some self-consumers select to not dump their surpluses into the community in a while intervals to keep away from having to pay for evacuation, as an alternative of receiving compensation in trade.

The value of those installations stays excessive and acts as a deterrent for a lot of home customers. However, the decline in latest instances has been forceful and, in keeping with the newest forecasts from the International Energy Agency (IEA), its decline will speed up within the coming years. A trajectory that’s powerfully paying homage to what has occurred lately within the photo voltaic panel market, whose value has plummeted, encouraging large- and small-scale startups.

“Storage systems allow us to make more efficient use of surpluses, that is, energy not self-consumed at the time it is generated, in order to be able to consume it at a later time,” says Donoso. “In the coming years, batteries are going to have the same importance as the solar panels themselves,” he predicts.

In the long run, these batteries are referred to as upon not solely to retailer vitality from the solar and generated by the self-consumption set up itself, but in addition to arbitrate between the most cost effective hours and days—in which there’s loads of renewable vitality—and the most costly. —through which, as an alternative of consuming vitality from the grid, they are often self-sufficient—. The advantages of this follow won’t solely be for the properties and corporations that set up them, however for {the electrical} system as an entire, which must rely much less usually on present backup applied sciences, corresponding to gasoline vegetation, dearer and polluting. For that future to be a actuality, nevertheless, the variety of installations has to develop a lot sooner within the close to future.
