Combining battery storage with solar generation is already cheaper than using diesel in most microgrids, said experts at an Energy Storage Report webinar last week.
“As the key applications, we see islanded grids or microgrids, [where] PV and batteries are becoming cost-competitive with diesel,” confirmed Valts Grintals from Delta Energy & Environment in the event organised alongside Ata Insights.
A case in point is France, where interest in solar plus storage is highest in islands and “non-interconnected zones,” where around 60% of PV projects so far have been installed with batteries, Grintals said.
This interest is set to grow following the launch of a tender last year for almost 52MW more of island-based solar capacity, spread across 33 projects. “We expect to see more storage coming into these projects,” said Grintals.
“In France, PV and storage is a great solution to stabilise the grid [and] help enable microgrid use, and it is already cost competitive.”
