Media: Building and curtailing solar ‘could be cheaper than battery storage’ (Energy Live)

From Energy Live News:

Building more solar and curtailing surplus electricity could be cheaper than adding battery storage. That’s according to a Solar Potential Analysis (SPA) report from MS Solar Pathways, which found installing more capacity and not using it all the time would be considerably less expensive than installing long-term or seasonal storage in Minnesota.

It notes storage would still play a significant part of a high renewables future because it expands the dispatch capabilities of wind and solar assets and can smooth out intermittency but shows overbuilding solar power facilities is a preferential option...

...Josh Quinnell, Senior Research Engineer at the Center for Energy and Environment and a contributor to the report, said: “It is cheaper to overbuild solar than it is to add enough storage to avoid curtailment. That is not to discount storage. “Storage is still important. We don’t have all the answers but certainly the results challenge traditional thinking.”
