The power plant consists of two boiler units: TE Plomin A, built in 1969 and TE Plomin B, built in 2000. Both are operated by Hrvatska elektroprivreda, and the latter was co-owned with RWE Power AG. On 28 May 2015, the contract signed by the two parties in 1996 expired, thereby transferring the thermal power plant into 100 percent ownership of HEP. They generate a total of 330 megawatt. In 2007 their total output was 2187 gigawatt-hours; in 2009 it was 1927 GWh.
