Guyana plans three utility-scale solar parks
The three new utility-scale projects in region ten of Guyana, with a combined capacity of 15 MW, form part of wider plans to deploy 33 MW of large-scale solar with accompanying energy storage across four of the country’s regions.
Battery storage in Spain could become unviable beyond 32 GWh
Scientists from the University of Seville have developed real-time optimization models showing that electricity storage in Spain may be approaching its economic limit, with cumulative capacities above 32 GWh depressing prices and undermining project profitability.
Global solar corporate funding reached $22.2 billion in 2025
While global solar corporate funding in 2025 fell to the lowest level recorded since 2020, deal count rose to its highest level since 2017. Mercom Capital Group says investors favored smaller, lower-risk, execution-ready projects last year amid policy uncertainty, trade pressures and higher financing costs.
