As Indonesia intensifies its commitment to achieving net-zero emissions by 2060, expectations for climate accountability and data transparency are growing across all industries, including those operating in renewable energy. While hydropower plays a key role in Indonesia’s low-carbon transition, companies are now expected to go beyond green labels and demonstrate real climate impact through robust GHG accounting, ESG integration, and climate risk management. In this context, Tamaris Hydro has emerged as one of the independent power producers proactively addressing these commitments with the support of Tri Hita Consulting.
Most recently, Tri Hita assisted Tamaris Hydro in verifying GHG emissions from one of its hydro projects, while also supporting the calculation and reporting of potential future emissions from upcoming sources. This technical verification process not only ensures the credibility of Tamaris Hydro’s emissions data, but also prepares the company to meet evolving reporting expectations and tap into future climate finance opportunities. By providing accurate data modeling and review mechanisms, Tri Hita enabled Tamaris to build confidence in its emissions disclosures.
Beyond emissions verification, Tri Hita has also supported Tamaris Hydro in crafting a broader climate strategy. Through a collaborative process, the two teams developed a comprehensive GHG roadmap and conducted a climate risk assessment that integrates physical and transition risks into corporate planning. This work has strengthened Tamaris Hydro’s ability to anticipate regulatory and environmental shifts, while setting realistic decarbonisation targets that reflect the company’s operational context and growth plans.
The collaboration also focused on building internal systems. Tri Hita supported Tamaris Hydro in improving its GHG inventory management and ESG data governance. By auditing the company’s data collection processes, Tri Hita helped identify inefficiencies and gaps, recommending improvements that ensured consistency and transparency.
What has made the partnership effective is the shared commitment to long-term improvement. Rather than approaching climate disclosure as a compliance checklist, Tamaris Hydro has consistently sought to deepen its internal capacity and align its operational strategies with broader sustainability goals. Tri Hita’s support throughout this journey has ranged from targeted training and technical reviews to strategic scenario planning, all tailored to the evolving needs of a dynamic hydropower company.
As Indonesia moves toward a more climate-resilient energy future, partnerships like this one demonstrate the value of sustained collaboration.
