Background

The Tonasa Cement Plant power station was built in two phases.[1] Phase 1, consisting of two 25 MW coal-fired generators, was completed in 1996 and provides power to the Tonasa IV cement works, which was completed in the same year. Phase 2, consisting of two 35 MW coal-fired generators, was completed in 2013 and provides power to the Tonasa V cement works, also completed in 2013.[2] The generators supply the majority of the power for the cement works, with the remaining supply coming from PLN, the Indonesian state-owned electricity provider.[3]

PT Semen Gresik's coal-fired power station co-fired with risk husk. In September 2023, the company signed a Memorandum of Understanding for the addition of refuse-derived fuel as a second co-firing fuel at the power station.[4]

Financing

Financing for the 70 MW Tonasa Phase II power station was closed in 2009. Bank Jatim, Bank Mandiri, BPD Sumatera Utara, and PT Bank Rakyat Indonesia (BRI) provided US$346.89 million in debt financing, and Pt Semen Indonesia provided US$171.44 million in equity. PB Capital and Rothschild acted as financial advisors.[5]
