Investors and developers use us for a single phase or for the whole lifecycle. The scope is the same either way: get the project buildable, then get it running.
Strategy and screening for greenfield sites and portfolio acquisitions.
Securing connection approvals, plus updates and amendments to existing ATRs.
Technical and commercial viability before capital is committed.
Engineering documentation for PV parks and battery storage systems.
Regulatory filings and compliance through the Romanian energy authority.
Coordination across contractors, authorities and grid operators.
Testing and handover of photovoltaic parks into commercial operation.
Independent review of permitting, grid status, documentation and development risk.
