Iberia raises its grid ceiling. Capital chases firm power.

Iberia just raised its grid ceiling — and global capital keeps chasing firm green power

One day, three signals on where deal economics are heading.
What we’re tracking today:
Portugal and Spain inaugurated the new 400 kV Minho–Galicia interconnection at Arbo — a ~€128m build by REN and Red Eléctrica lifting sustained commercial exchange capacity to 3,000 MW in both directions. Deeper Iberian coupling means lower curtailment risk and stronger capture prices for solar, wind and storage assets.
SK Inc and KKR launched a US$1.29bn renewables platform in South Korea — 1.7 GW operating today, scaling towards 10 GW — with KKR taking control to serve AI data-centre load. Big capital is consolidating operating fleets around firm demand.
Tesla deployed 13.5 GWh of energy storage in Q2 2026, up 40% year-on-year and its second-best quarter ever. Global BESS demand keeps compounding — and keeps underwriting the value of storage-attached projects.

At Persimmon Investments, stronger grids and firmer demand are exactly the map we invest against.
