Indonesia's First EPD in Power Generation

Realizing Indonesia’s First Environmental Product Declaration in Power Generation Industry

About

PLN Indonesia Power is one of the subsidiaries of PT Perusahaan Listrik Negara (PLN) (Persero) which was established on October 3, 1995, under the name PT PLN Pembangkitan Jawa Bali I (PT PJB I). On October 8, 2000, PT PJB I was renamed Indonesia Power as an affirmation of the Company’s goal to become a pure, business-oriented, independent power company. The Company’s main business activities are focusing on a provider of electricity through power generation and provider of operations and maintenance of power plants that operate plants spread across Indonesia. In addition to managing Generating Units, Indonesia Power has 5 Subsidiaries, 2 Joint Venture Companies, 1 Associate Company, and 3 Grandson Companies (Affiliates of Subsidiaries) to support the company’s business strategy and processes. Located on a 70-hectare site at Pasuruan, East Java province, Grati Power Generation and O&M Service Unit (POMU) combined-cycle power plant is one of the Power Generation Units (PGU) owned and operated by PLN Indonesia Power.  

In 2021, Grati POMU successfully achieved the highest level of award in the corporate performance rating assessment program in environmental management called PROPER by the Ministry of Environment and Forestry of the Republic of Indonesia. Grati POMU won the GOLD PROPER Award and is considered to have succeeded if fulfilling the assessment criteria of beyond compliance. 


Challenge

The Grati POMU combined-cycle power plant is playing an increasingly important role in supporting the Java-Bali electricity grid. The Grati POMU operates the combined-cycle power plant with an installed total capacity of 1460 MW that is generated by 3 blocks. Block I consists of 3 gas turbines (100.75 MW for each unit) and 1 steam turbine with 159.58 MW. Block II consists of 3 gas turbines (100.75 MW for each unit) and 1 steam turbine with 195 MW,  and Block III consists of 2 gas turbines (153 MW for each unit) and 1 steam turbine with 195 MW. In 2022, in order to fulfill one of the assessment criteria for the PROPER award, which is life cycle assessment (LCA), and maintain its GOLD PROPER award, Grati POMU was aiming to obtain Indonesia’s first Environmental Product Declaration in the power generation industry. 


Solution

In 2021, Grati POMU completed the LCA study for its electricity product together with Ailesh with the scope of Cradle-to-Grave and successfully fulfilled the assessment criteria, and achieved the GOLD PROPER award. To maintain the award in 2022 and achieve a higher score, we conducted an improved life cycle assessment in accordance with the Product Category Rules for Electricity from the International EPD System so Grati POMU can register and verify its environmental performance result to the International EPD system and obtain the Environmental Product Declaration. 


Benefit

With the LCA being implemented as a powerful tool to assess the potential environmental impact of the electricity product, Grati POMU was not only contributing to a more sustainable future for Indonesia but also realizing Indonesia’s first Environmental Product Declaration with the international recognition of its environmental performance from the International EPD System.
