The UK becomes one of the most favourable market thanks to favourable regulations, granting co-located assets access to multiple markets and offering faster grid access for co-located renewables projects. The Ireland I-SEM is rated high in Aurora Energy’s study because of its beneficial legislation that facilitates faster grid access and high curtailment risks to renewables.

Regarding policies and regulations, a total of five countries are rated as the most favourable markets in the report. The Polish market offers accessibility to long-term capacity market revenues and novel cable pooling regulation, while Hungary introduced mandatory co-location for solar PV assets “above a certain size.”

Meanwhile in France, co-located solar PV systems can participate in French contract for differences (CfD) auctions, which have historically cleared at high strike prices. The Ireland I-SEM and UK markets are favourable due to the variety of available revenue streams for projects and potential benefits in terms of grid access and curtailment risks.

Looking forward, Aurora Energy predicted an additional 421GW of intermittent renewables capacity by 2030, which will pose significant risks to renewables assets such as the cannibalisation of capture prices, increasing curtailment and rising imbalance costs. Germany, Greece, the Netherlands and the Ireland I-SEM will be most affected, but they can opt for co-location projects to mitigate the risks.

Recently, PV Tech published an article written by Aurora Energy Research’s research lead expert of Southeastern Europe Panos Kefalas, who examined the key trends of co-location in the region.

A panel discussion on the business opportunities for co-located solar and energy storage projects was covered at the Energy Storage Summit 2024 conference earlier this year.
