The case for implementing storage in electricity networks should be based on long-term weather analyses, attendees at the Energy Storage World Forum will hear.

Including weather patterns as one of the main variables in a business case analysis will help show niches where storage “makes a lot of sense,” said Dr Björn Peters, who will be speaking on the topic at the Forum in Berlin this May.

For off-grid mining operations in hot climates, for example, “there might be a very good business case for solar storage” compared to diesel.

Within grids, meanwhile, storage can offer value in helping to balance out short-term fluctuations in intermittent renewable energy.

However, Peters’ research is worrying for policy makers who hope to rely completely on intermittent renewable energy generation to reach European carbon reduction targets.

A surprise U-turn over a UK nuclear power plant has ignited debate over whether renewables, backed by storage, might not be a better alternative.

Last month the UK’s new, post-Brexit administration raised eyebrows after announcing a further review of Hinkley Point C, a controversial nuclear power plant that was supposed to have been given the final go-ahead on July 29.

UK officials rushed to issue assurances after the postponement threatened to spark tensions with China and France, the international partners in the GBP£18bn project.

“The UK needs a reliable and secure energy supply and the government believes that nuclear energy is an important part of the mix,” soothed Greg Clark, business, energy and industrial strategy secretary, in press reports.

The government said it would now make its final decision “in early autumn,” he said.
