Solar and storage cut summer wholesale power prices 42% in Texas and 51% in California over five years
By Eve
Analysis by the Solar Energy Industries Association shows that rapid expansion of solar and battery storage drove down average wholesale electricity prices by 42% in Texas and 51% in California between summer 2021 and summer 2026, despite rising demand. Solar generation rose 421% in Texas and 90% in California, while battery storage capacity grew more than 26 fold in Texas and nearly sevenfold in California. The price reductions saved Texans approximately 3.55 billion dollars and Californians approximately 2.5 billion dollars during June to August 2026 compared with the same period in 2021.
Why it matters
Lower wholesale electricity costs can reduce operating expenses for charge point operators and improve the business case for new EV charging infrastructure in both states. The demonstrated price suppression effect of solar and storage may influence procurement decisions and site economics for CPOs planning deployments in high demand growth markets.

Australian rooftop solar installations hit record pace but maintenance gaps threaten asset lifespan
Australia installed roughly 181,000 rooftop solar systems in the first half of 2026, 35% more than the same period in 2025, marking the strongest six month result since 2021. The country now has more than 28 gigawatts of rooftop solar installed, the most per capita globally, with roughly 36% of households owning a system. Andrew Barrington of Solar Shine Australia warned that the industry focuses on new installations while neglecting maintenance of existing systems designed to operate for 25 years or longer, according to pv magazine.
Why it matters
For CPOs and infrastructure operators, the maintenance gap in Australia's 28 gigawatt rooftop solar base signals a potential service market and highlights operational risks if distributed energy assets degrade prematurely. The warning underscores the need for asset management protocols as solar becomes critical grid infrastructure, a lesson applicable to EV charging networks also designed for multi decade lifespans.
Octopus Energy app showed tripled home electricity use but bills revealed display error
An Octopus Energy customer in the UK reported that the supplier's app appeared to show household electricity use tripling after 27 August, despite no change in charging behaviour for their EV or use of solar, battery storage and heat pump. The customer later confirmed the issue was with app data presentation, not actual billed consumption, with another user noting missing data from previous months distorted the display.
Why it matters
App display errors can prompt EV drivers to alter charging routines unnecessarily, undermining confidence in smart tariff tools that underpin flexible demand management for charge point operators and grid services.
Finland grants operating licence for world's first permanent deep geological nuclear waste repository
The Finnish government has issued an operating licence for the Onkalo facility in Eurajoki, the world's first permanent deep geological repository for spent nuclear fuel. The facility will store radioactive waste more than 400 metres underground in approximately 1.9 billion year old crystalline rock. Used fuel rods from the Olkiluoto and Loviisa nuclear plants will be placed in thick copper canisters, lowered into underground vaults, and surrounded by bentonite clay, with the system designed to isolate nuclear waste for over 100,000 years.
Why it matters
This milestone establishes a proven model for permanent nuclear waste disposal that could influence energy infrastructure planning globally, including for countries expanding nuclear capacity to support electrification and EV charging networks. The long term waste solution may reduce regulatory barriers for new nuclear projects that could provide baseload power for large scale charging infrastructure.
