Our studies covered site assessments, demand profiling, system design, energy yield analysis, grid impact evaluations, and cost estimation, ensuring technically and economically sound project implementation. These initiatives support the government’s agenda to expand electricity access and increase the share of renewable energy in the national energy mix.

CBS supported PT Sarana Multi Infrastruktur (PT SMI) in evaluating the technical and financial feasibility of the 5 MWe Waste-to-Energy (PLTSa) project in Surakarta as part of its financing consideration. Our team conducted a critical review of the existing feasibility study (FS) and front-end engineering design (FEED), assessing waste characterization, technology selection—including wet pyrolysis and gasification—process design, plant performance, and investment costs. The study also included a site investigation of the demonstration plant to validate key technical assumptions.
The findings provided key insights into the project's viability, supporting informed PT SMI’s financing decisions and promoting sustainable waste-to-energy development in Indonesia.

CBS supported the UNDP’s MTRE3 Project in advancing climate change mitigation in Indonesia’s power sector across four provinces (Riau, Jambi, East Nusa Tenggara, and West Sulawesi). The study focused on scaling up renewable energy deployment by analyzing emission sources, abatement potential, and mitigation costs.
We developed a Marginal Abatement Cost Curve (MACC) based on existing initiatives, including PLN’s RUPTL and provincial energy plans, to assess various renewable energy options—geothermal, biogas, biomass gasification, biomass co-firing, municipal solid waste gasification, hydro, mini-hydro, solar PV, wind, and tidal power. The findings provided policymakers with insights into cost-effective renewable options to transform the power sector. The project also included extensive data collection, techno-economic assessments, and capacity-building activities to strengthen national and provincial capabilities in renewable energy planning.

Under the UNDP’s MTRE3 Project, CBS led the development of GHG inventories and reference baselines for the energy sector in four pilot provinces (Riau, Jambi, East Nusa Tenggara, and West Sulawesi), covering energy industries, manufacturing, transportation, residential, commercial, and fugitive emissions. By analyzing historical emissions trends, we projected baseline scenarios using LEAP to serve as benchmarks for provincial mitigation planning.
The project aligned with international and national GHG accounting standards and involved extensive data collection, emissions analysis, and stakeholder training. Through capacity-building activities at the provincial level, we supported strengthening local capabilities to integrate low-carbon strategies into energy planning.

CBS assisted the Ministry of Industry and UNDP in developing efforts to reduce the release of unintentional persistent organic pollutants (UPOPs) from unsound plastics recycling practices, particularly in e-waste management. The project focused on developing technical guidelines to minimize emissions of UPOPs, particularly brominated dioxins and furans (PBDDs/FS), incorporating the best available techniques and best environmental practices (BAT/BEP) from the Stockholm Convention.
Through targeted workshops and hands-on training for recyclers and industry associations, we support the strengthening of stakeholder awareness and capacity to promote cleaner and more sustainable plastics recycling in Indonesia. We worked closely with government agencies and industry stakeholders throughout the project to ensure ongoing coordination and practical implementation of the guidelines.

CBS collaborated with UNDP to enhance sustainable waste management and pollution control as part of a program aimed at reducing Polybrominated Diphenyl Ethers (PBDEs) and Unintentional Persistent Organic Pollutants (UPOPs) emissions from plastic recycling and manufacturing in Indonesia. Key activities included disseminating technical guidelines to recyclers in East Java, developing a regulatory framework for PBDE-containing waste, and designing wastewater treatment guidelines for small and medium-sized textile industries.
Additionally, we conducted a pre-feasibility study for a recycling facility in Bandung and assessed the operational conditions of an e-waste collection facility in Depok. These efforts contributed to strengthening Indonesia’s regulatory and technical capacity for environmentally sound waste management.

CBS provided technical expertise for the feasibility study, preliminary design, and front-end engineering design (FEED) of Indonesia’s first government-initiated lignite gasification power plant in Kotabaru, South Kalimantan. As a pioneering project in its development phase, it aimed to assess the viability of gasification as an energy pathway, leveraging local lignite resources.
The study covered key aspects such as site selection, technology assessment, feedstock characterization, process and environmental analysis, plant performance evaluation, and financial modeling. The FEED phase followed a structured approach, including defining the basis of design, conducting multidisciplinary basic engineering, and developing project management plans, providing a robust foundation for future project advancement.
