German startup EDENenergy ships 70 kWh storage system built from 112 second-life e-scooter batteries
By Eve
EDENenergy, a German startup with three founders and three part-time staff, has shipped its first commercial product, a 70 kWh energy storage system using 112 repurposed e-scooter batteries. The founders, formerly researchers at Fraunhofer ISE, expected the used batteries to retain roughly 80% of their life, but testing showed most kept about 90% of original capacity. The company plans for future systems to accommodate multiple battery types in the same enclosure, as reported in the publication's coverage of second-life storage.
Why it matters
Second-life battery storage could offer a lower-cost option for buffering grid constraints at charging sites, although a 70 kWh first product shows the approach is still at an early commercial stage. Procurement teams may want to track how testing, warranties and mixed-chemistry enclosures develop before considering it for site-level storage.

Recurrent Energy brings Court Barton solar farm in the UK into commercial operation
Recurrent Energy has brought the Court Barton solar farm in the UK into commercial operation, according to a CSIQ Stock News item. The source describes the completed project as moving part of Recurrent Energy's development pipeline into operating infrastructure, and gives no capacity, grid connection or offtake figures. The same page also lists unrelated items, including an Elong Power subsidiary's three year cooperation agreement worth at least RMB2 billion (about US$300 million) for domestic grid side energy storage supply.
Why it matters
A newly operating UK solar asset shows developer pipelines turning into live generation, which can matter for those sourcing renewable power or looking at co-located charging. With no capacity or offtake details disclosed, it is a market signal rather than something to act on directly.
Grid Users Coalition says 82.8% of logistics businesses lack the grid capacity they need
The Grid Users Coalition, a group of twelve business bodies including Logistics UK, the Road Haulage Association and ChargeUK, reports that 82.8% of logistics businesses lack the grid capacity they need. It says the Budget's grid measures do little to change this, as electricity price relief goes to around 10,000 energy-intensive manufacturers and faster connections go to strategic data centres and other strategically important projects. Its report, Grid Access for Growth, sets out low-cost fixes, most needing no new public money, and the coalition has written to the Secretary of State for Energy Security and Net Zero asking for a meeting.
Why it matters
Logistics depots and charging hubs remain in the connection queue, so project timelines and site viability for depot and public charging work still hinge on grid access. CPOs and fleet operators should watch whether the coalition's proposed fixes gain traction with government and the regulator, as they could shorten waits for non-priority sites.
Britain curtailed 1,789 GWh of wind over 30 days, paying wind farms £51.5 million to cut output
The National Energy System Operator curtailed 1,789 gigawatt-hours of wind generation over a 30 day period, with net payments to wind farms for reducing output totalling £51.5 million ($69.4 million). That equated to one-fifth of potential grid-scale wind generation, or 17% once estimated output from smaller wind farms on local networks is included. Scottish wind farms accounted for over 99% of the curtailed power, as transmission lines to England reach capacity on windy days, with the B6 boundary the tightest bottleneck. The figures were reported by The Cool Down, citing Electricity Live data shared on Reddit.
Why it matters
Constraint costs from grid bottlenecks are ultimately borne by households, and they show how much usable low carbon power is stranded in Scotland while gas plants elsewhere ramp up. For CPOs and procurement teams, this strengthens the case for demand that can absorb surplus power and for siting and flexibility decisions that account for regional grid constraints.
