Ground-mounted and rooftop solar PV
Our team develops ground-mounted and rooftop solar PV projects, from site survey to grid connection.
Solar PV and energy storageFrom land to grid.
We develop solar PV and energy storage projects that strengthen the power grid, on land and rooftops that stay in their owners’ hands.

What we do
Four disciplines, one method.
Grid-connected stand-alone storage
Battery energy storage systems (BESS) from 1 MW up to more than 50 MW, developed through to ready-to-build.
Project development
From land to ready-to-build: studies, permits, grid connection and contracts, on our own account or for our partners.
Land and grid connection
A catalogue of more than 2,000 plots and a close reading of grid capacity, to place each project where the grid can take it.
Energy storage, explained
Store energy when there is too much, return it when there is too little.
A storage facility takes up the space of one or a few shipping containers. No engines, no fumes: it charges and discharges as the grid needs.

Midday
The grid has energy to spare
Solar plants produce more than is consumed. The facility stores the surplus instead of wasting it.
Evening and night
Demand rises as the sun sets
The facility returns the stored energy to the grid, exactly when homes and businesses need it most.
At every moment
A more stable grid
It responds in a fraction of a second to hold voltage and frequency. Across Europe, grid stability has become a priority, especially since the Iberian blackout of 28 April 2025.
Three ways to work with us
Landowners
Your land can earn a rent for 30 years.
For storage and for solar PV, from 200 m² to more than 5 hectares. Studies and permitting are on us.
See the terms MunicipalitiesA public-interest facility that protects the local grid.
A small footprint, noise and fire rules met, revenue for the municipality and a single point of contact throughout the project.
See the benefits PartnersVerified sites, developed through to grid connection.
For operators, IPPs and developers: greenfield projects, sourcing of ready-to-build projects and equity stakes, across four European markets.
See the modelHow we work
Six steps to a ready-to-build project. We take care of everything*.
Site verification
Grid capacity, medium-voltage line, land registry, zoning and environmental constraints.
Agreement with the landowner
Site visit, written terms and a signed lease option.
Meeting the municipality
Project presentation and zoning confirmation before any application.
Access and connection request
Application to the grid operator, under each country’s connection regime.
Permits
Local permits and regional or national authorisations, depending on the country and land type.
Connection and notarised lease
Connection agreement signed and lease executed before a notary: the project is ready to build.
* Steps, timelines and permits vary by country and type of project.
Our markets
Solar PV and storage across four European markets.
Our company is headquartered in Sofia. We develop projects where the grid needs new capacity and flexibility.

The team
A dedicated, professional, responsive and resourceful team at your side.
Our team brings together energy project development specialists: land, planning, grid engineering, permitting and contracts. We verify before promising, put the terms in writing and follow every file through to connection.
Project development
Land prospecting, negotiation and file management.
Grid and electrical engineering
Substation capacity, connection and sizing.
Planning and permitting
Land compatibility, studies and permit applications.
In-house analysis tools
Grid, cadastre and planning data cross-checked and updated continuously.
Market watch
Energy storage across Europe
Second MACSE auction: 16 GWh of storage
Terna holds the second auction of the MACSE mechanism, for 16 GWh of storage to be delivered in 2029.
