Company profile
Solar by day, stored power after sunset
Grenergy develops, builds and operates solar and battery projects, but its storage business has two distinct formats. Oasis co-locates photovoltaic generation with batteries to shift solar output into non-solar hours; Greenbox connects stand-alone batteries directly to the grid. The group links project origination and construction with plant operations and large-scale power contracts across Europe, Latin America and the United States.
Integrated operating model
From site selection to the control room
Teams assess sites, test feasibility, obtain permits and plan projects before in-house design and integrated construction management. Once a plant is live, remote and field specialists plan maintenance, monitor it in real time and manage risk; the power team works with offtakers under large-scale contracts. These pages describe group capabilities across the life cycle, not a claim that every project remains owned by Grenergy.

Hybrid power in Chile
When the Atacama sun sets, the batteries keep supplying
Oasis de Atacama combines solar and storage so electricity can be delivered beyond daylight hours. Its project page dates operations from 2024; Grenergy's current full-platform plan is 2.5 GW of PV and 14.1 GWh of batteries. Central Oasis is a separate five-phase replication in central Chile, planned at 1.4 GW and 5.1 GWh for 2027. Codelco is an offtaker under a 24/7 PPA, while BYD supplies 2.6 GWh of batteries for four named phases.

Two Spanish storage formats
Escuderos couples solar and batteries; Oviedo stands alone
Iberian Oasis is under development at 1 GW of solar and 3.2 GWh of storage. Its Escuderos phase includes 200 MW of solar already operating, 680 MWh of planned storage and a signed PPA; Índalo adds a planned 100 MW and 320 MWh. Oviedo instead is a stand-alone four-hour battery: 154 MW and 618 MWh on a former industrial site, expected to enter operation in the first half of 2027.

Strategy and geography
Two platforms anchor a €3.7bn plan
Grenergy's May 2026 plan allocates €3.7 billion through 2028, with roughly 45% intended for Europe, 45% for Chile and about 5% for the United States. It targets 8 GWh of Greenbox capacity in operation or construction by 2028 across six European markets, while all Oasis platforms are planned at 5 GW of solar and 22 GWh of storage. These are company targets and pipeline figures, not delivered capacity.
