Batteries to cut renewable energy costs in Europe

Europe’s renewable energy sector is set for a major shift as falling battery prices remove key barriers to wind and solar power. Industry analysts report that battery storage costs have dropped by more than 70% in the past decade, making large-scale storage projects economically viable. The decline in battery prices directly challenges the traditional argument that renewables are unreliable due to their intermittent supply. With batteries now able to store excess energy during peak production and release it when demand rises, solar and wind farms can operate more consistently. This development is expected to accelerate the phase-out of fossil fuel plants across the continent. Major European energy companies have already started integrating large battery systems into their grids. In Germany, for example, utility provider RWE commissioned a 100-megawatt battery storage facility last year. Similar projects are underway in Spain and the Netherlands, where grid operators are testing systems to balance supply and demand without relying on conventional power sources. Analysts at BloombergNEF predict that battery storage capacity in Europe will grow fivefold by 2030. The expansion is driven by stricter EU climate policies and the need to meet renewable energy targets. Governments are also offering subsidies to encourage private investment in storage infrastructure. The shift comes as Europe aims to cut greenhouse gas emissions by 55% by 2030. Cheaper batteries are now making it possible to store renewable energy efficiently, reducing the need for backup gas plants and lowering overall energy costs for consumers. Source: tu.no
