Korkia has secured grid connection permits for its Iron Gates hybrid portfolio in Romania, marking a significant development milestone for the Finnish renewable energy company as the country prepares to overhaul its grid access framework.

Permits Issued by Romania's Transmission System Operator

The grid connection permits, known as Avize Tehnice de Racordare or ATRs, were issued in May 2026 by Transelectrica, Romania's transmission system operator.

The Iron Gates portfolio is located in Caraș-Severin County in southwestern Romania and consists of two hybrid projects with a combined solar PV generation capacity of 273 MW and a total battery energy storage system capacity of 250 MW.

Under Romanian grid connection regulations, an ATR is a critical step in the development process, confirming the technical and economic conditions for connecting a project to the electricity network.

The permits establish the framework under which projects can export electricity to, and import it from, the grid, and provide a defined pathway to grid connection.

Timing Coincides With Sweeping Changes to Romania's Grid Access Rules

The timing of the permit issuance is particularly notable given the changes underway in Romania's renewable energy sector. New measures are being introduced aimed at ensuring the efficient allocation and utilisation of network infrastructure.

These include additional financial guarantee requirements, stricter implementation obligations, and changes to the framework governing access to grid capacity, with the regulator shifting to a competitive auction-based mechanism.

By securing ATRs under the existing regulatory framework before these changes take effect, Korkia has locked in an approved connection pathway for the Iron Gates projects, providing what the company describes as significant protection against development risk. The permits are expected to strengthen the projects' route to Ready-to-Build status, which Korkia is targeting for 2027.

Michael Roussos, Country Manager for Romania at Korkia, said that grid access, project maturity, and execution capability have become more important than ever as the Romanian market matures and competition for available grid capacity intensifies.

"As Romania continues to modernise its grid connection framework and introduce stricter requirements for developers, high-quality projects with advanced permitting status can stand out from the large pipeline of speculative applications," he said.

Roussos added that securing connection rights for the Iron Gates portfolio provides the projects with a clear connection pathway and further strengthens Korkia's Romanian development platform through its partnership with Econous Green Energy.

Iron Gates Adds to a Growing Romanian Portfolio

The Iron Gates permits come in addition to ATRs previously secured for Korkia's Alexandria portfolio in Romania. With both portfolios now holding advanced connection rights, Korkia has progressed nearly 600 MW of solar PV capacity and over 550 MW of co-located battery storage capacity to mature stages of development across its Romanian platform.

Hybrid projects combining solar generation and battery storage are described by Korkia as playing an increasingly important role in Romania's energy transition, supporting grid flexibility, improving the utilisation of network infrastructure and enabling the integration of larger volumes of renewable generation.

Part of a Broader 15 GW Global Development Pipeline

The Iron Gates milestone sits within a wider global expansion by Korkia. The company's renewable energy portfolio currently comprises 15 gigawatts of mature and 9 gigawatts of early-stage utility-scale solar, wind, and energy storage development assets spanning eight countries across Europe and North and South America.

In 2026, the company has recorded multiple development milestones across its international portfolio, including the exit of two fully permitted solar PV projects and a 10.7 MW portfolio of solar PV assets in northern Italy.
