New or bigger grid connection in Croatia: how long may it take and who do I complain to?
A new home, a heat pump, a charging point or solar panels can need a new or bigger connection. The grid operator does this work, and many countries set deadlines and rules on costs.
📜 The rules in Croatia
Grid connection
For a simple household connection, HEP ODS must issue the electricity approval (EES) within 15 days of a complete request and send a connection offer, valid for two years. It must build the connection within 30 days of full payment of the connection fee.
- The 30-day build deadline applies only if your installation meets the conditions for a network-use contract. These rules were adopted by HEP ODS in 2023 with HERA's prior consent. (hep.hr)
