Managed EV charging cuts on-peak demand by up to 93%, deferring grid upgrades
By Eve
A Brattle Group study commissioned by EnergyHub, based on a Washington State trial, found that active managed charging can reduce on-peak EV charging by 59% to 93% compared to unmanaged charging. The report, titled 'Demonstrating the Full Value of Managed Electric Vehicle Charging', shows that managed charging strategies increase hosting capacity and defer capital expenditures, offering a scalable solution to accommodate EV growth without overburdening existing electricity infrastructure.
Why it matters
For charge point operators and grid planners, managed charging presents a proven method to avoid costly distribution system upgrades while supporting higher EV adoption rates. The 59% to 93% reduction in on-peak demand demonstrates a tangible pathway to expand charging networks within existing grid constraints.

French startup repurposes used EV batteries for solar energy storage
A French startup is integrating reconditioned electric vehicle batteries into solar energy storage systems. After around ten years of automotive use, EV batteries typically retain 70 to 80 per cent of their original capacity, which is insufficient for vehicle range but adequate for stationary storage applications that face less demanding performance requirements than onboard automotive use.
Why it matters
Second life battery storage can lower the capital cost of grid scale and commercial solar installations, potentially reducing electricity costs for depot and forecourt charging operators. The technology also extends battery value chains, which may influence residual values and total cost of ownership calculations in fleet procurement.
Renault Group and EDF partner to accelerate bidirectional charging in France
Renault Group and EDF Group have launched a partnership in France to offer an integrated EV solution combining electric cars with home charging systems and smart charging capabilities, including bidirectional charging, vehicle to grid (V2G), and vehicle to home (V2H). The package will be available to private customers through Renault dealerships from summer next year, with home charger installation handled by EDF subsidiary IZI and smart charging management provided by DREEV. The partnership will expand to all bidirectional capable EVs within the Renault Group, including the Renault 5, Renault Twingo, and Dacia Spring.
Why it matters
This partnership creates a new integrated procurement route for home charging infrastructure in France, bundling hardware installation and smart charging services through a single OEM and utility collaboration. The focus on bidirectional technology positions EDF and Renault to capture value from V2G and V2H services, potentially reshaping how residential charging infrastructure is specified and deployed at scale.
South Africa to procure 4,600MW battery storage and 5,000MW gas power to cut curtailment
Electricity and energy minister Kgosientsho Ramokgopa announced on Wednesday that South Africa will prioritise procurement of 4,600MW of battery energy storage systems and 5,000MW of gas to power generation under its Integrated Resource Plan unveiled last year. The 9,600MW combined allocation addresses immediate needs for storage, flexibility and dispatchable supply as rising curtailment increases system costs. The country also plans to build 14,000km of new high voltage transmission lines over the next decade at an estimated cost of R440bn to connect new wind, solar, battery storage and gas projects to the national grid.
Why it matters
The 4,600MW battery storage procurement represents a major opportunity for energy storage developers and EPC contractors in South Africa's rapidly diversifying power market. The parallel transmission investment of R440bn signals substantial grid infrastructure work to support renewable and storage integration, creating a pipeline for electrical contractors and equipment suppliers.
