Homeowner asks Reddit if an idle EcoFlow battery can run two garage fridges overnight
By Eve
A homeowner with an 8-kilowatt rooftop solar system and an EcoFlow Delta 3 Ultra Plus asked on Reddit's r/Ecoflow_Community whether moving the battery to the garage to power two refrigerators overnight would cut grid use. The battery currently charges between 9 a.m. and 4 p.m. to a 90% target, and the top reply said the plan was doable, suggesting charging from solar and drawing from the grid only if charge falls below a threshold such as 25%. A second user agreed and advised testing for a few days to see how much battery the fridges use, as reported by The Cool Down.
Why it matters
The thread shows household demand for simple solar-plus-storage use cases that shift consumption away from the grid, a signal for those weighing residential storage and managed charging offers. It is anecdotal, with no measured savings, so treat it as a sentiment indicator rather than market data.

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.
