Rising air injection rates boost compressed air energy storage efficiency
Chinese researchers have analyzed how different air injection strategies affect energy storage rates and heat losses in compressed air energy storage caverns. They found that a linearly increasing air flow rate can raise the energy storage rate from 85.5% to 87.5% compared with constant-rate injection.

Italy raises Macse energy storage auction premium cap from €22,000 to €27,000/MWh
Italy’s energy regulator, Arera, has raised the MACSE auction premium cap to €27,000/MWh per year, up from €22,000/MWh proposed in July, mainly due to higher benchmark investment costs. The new cap affects project economics and guarantees, while developers must weigh the 15-year fixed premium against potential merchant revenues when setting their bids.

Weaker monsoon lifts irradiance in western India as August storms dim the east
In a new weekly update for pv magazine, Solcast, a DNV company, reports that northwestern and southern India and Pakistan recorded above-average solar irradiance during the 2026 summer monsoon, benefiting major PV-producing regions, while tropical depressions drove irradiance sharply below average across eastern and central India. Favorable solar conditions helped support Indian PV generation and electricity exports to Nepal after late-August floods damaged hydropower plants and other energy infrastructure there.

Shedding light on ultraviolet-induced degradation
Recent testing to better understand power degradation during highly accelerated UV exposure indicates that ultraviolet-induced degradation observed in the laboratory is real, partially reversible, and – perhaps most importantly – entirely preventable. Cherif Kedir of the Renewable Energy Test Center (RETC) shares the results of its latest round of module testing.

Coordination can bring value to Brazil
More curtailment and steeper ramp rates are proving costly in Brazil, but a lack of regulation for virtual power plants (VPPs) is limiting the potential for distributed assets to smooth out the demand curve. Henrique Ribeiro from S&P Global explains how VPPs could better support Brazil’s transition while reducing reliance on expensive thermal generators.

EU inverter restrictions could shift from countries to individual high-risk suppliers
Proposed amendments to the EU’s Cybersecurity Act 2 would shift the assessment of “high-risk” suppliers from a country-based approach toward individual company evaluations. The changes could affect how restrictions on solar inverter suppliers are applied, although specific suppliers and measures should be determined at a later stage.
