Spanish solar industry group estimates solar avoided €17.02 billion in wholesale power costs over 18 months
By Eve
Spain's solar association UNEF calculated an average day-ahead price of €60.2 per megawatt-hour from January 2025 through June 2026, against roughly €112 without solar, or 86% higher. Of the €17.02 billion avoided, €14.23 billion came from solar generation and €2.79 billion from self-consumption, as reported by Saur Energy and republished by The Cool Down. The report also says gas affected Spain's electricity market in only 9% of hours.
Why it matters
Lower wholesale prices driven by solar feed into the energy cost assumptions behind charging site business cases and power purchase negotiations in Spain. Note that the figures are an industry association estimate, so buyers should treat them as indicative rather than independently verified.

National Grid appoints BAM UK and Ireland for Eastern Green Link 3 southern converter station works
National Grid has appointed BAM UK and Ireland to deliver major works for the southern converter station on Eastern Green Link 3 (EGL3), which is jointly developed by National Grid Electricity Transmission and SSEN Transmission. The proposed link runs between Peterhead in Aberdeenshire and Walpole in Norfolk, with about 436km of HVDC subsea cable in English waters coming ashore north of Anderby Creek in Lincolnshire, and around 5km of underground HVAC cable connecting the converter station to the proposed 400kV Walpole B substation. Project Director Mark Brackley said the award is an important step as the project moves into its next phase of delivery.
Why it matters
Added transmission capacity between Scotland and England is intended to reduce network constraints and carry more renewable power to where it is needed, which supports the grid headroom that future charging demand will rely on. For CPOs and developers, it is a signal of continuing grid reinforcement, though the link is still described as proposed and the benefits will arrive over the longer term.
Homeowner cuts boiler meter grid use from 2,100 to 800 kWh a year with solar, asks about going battery free
A homeowner posting in Reddit's r/Victron said annual grid electricity use on the meter serving their water boiler fell from 2,100 kWh to 800 kWh after installing seven Leapton 460 watt panels, 3,220 watts in total. The setup also includes an Eco-solar boost 3000 MPPT inverter, protection equipment and a three position switch to select grid or solar supply for the boiler. The account, reported by The Cool Down, notes the owner then asked about running fully off-grid without batteries, and one commenter warned that PV output is too variable for most electronics.
Why it matters
The example shows how direct solar use for a single flexible load can cut grid draw sharply without storage, but it also highlights the limits of battery free operation for sensitive electronics. For CPOs and procurement teams, it is a reminder that variable PV output needs buffering or grid support when supplying loads that need stable power, such as charging equipment.
Hyundai Ioniq 5 and Anker Solix S5000 backup battery power a US home during a simulated outage
A US homeowner posted on Reddit's r/AnkerSOLIXCommunity that they connected an Anker Solix S5000 to their home's electrical panel, with a Hyundai Ioniq 5 acting as an additional power source through a vehicle-to-load adapter. The install took about two hours and used a panel interlock and a generator inlet on a 30-amp breaker, with the S5000 reporting roughly 1,700 watts of charging input while supplying the house at 240 volts. The account was reported by The Cool Down and is a single user's experience rather than a tested result.
Why it matters
It shows growing consumer interest in using EVs as home backup power, a use case that could shape expectations for bidirectional capable chargers and vehicle-to-load features in residential and fleet procurement. The anecdote is unverified and small in scale, so treat it as a demand signal rather than evidence of performance.
