Position as at 2 October 2026
The Transelectrica connection register has five fields worth understanding before you screen anything with it, and two of them are trained into most readers wrong.
Technology labels need a sanity check, not a straight read. The register's four biogas entries average close to 750 MW approved each. Biogas plants do not run at that scale. Read an outlier like that as a data-entry artifact before you read it as a project.
Approved MW is the reliable figure. Commissioned MW is not: across every technology category in the current snapshot, that field reads zero. It is an unpopulated field, not a market fact, and treating it as one will misstate how much of Romania's approved pipeline has actually been built.
Remaining MW is not a for-sale signal. Where it is populated at all, it is usually close to zero, and it does not mean the balance of the approved capacity is available to a new entrant at that connection point.
"Valabil" (valid) covers 5,080 of the register's 5,119 entries. That is not a sign the market is healthy or static, it is a sign that most of the register was issued in 2024 and 2025 and has not had time to lapse. A near-universal status value carries almost no information on its own.
And the county field needs the same scepticism: 105 distinct spellings for 42 counties. Normalise before you rank anything by location.
