Meet our leadership & project team

Bali Energy Limited is the company developing the Bedugul geothermal project in Bali, Indonesia.

Established in Bermuda in 1994, BEL’s work at Bedugul spans exploration, drilling and technical studies. The project has its foundation in the Joint Operation Contract with Pertamina and the Energy Sales Contract with Pertamina and PLN, originally signed in 1995.

Our focus is to turn that foundation into a carefully staged development, bringing technical rigour and respect for Bali’s distinctive natural and cultural setting.

Experience across disciplines.
A shared focus on Bedugul.

Our leadership and project team bring experience in energy, engineering, finance, public policy and project administration.

One resource.
A measured path forward.

Bedugul is planned in three stages: an initial 5–10 MW, a further 55–60 MW and another 110 MW. The ranges reflect the original plan and the Ministry of Energy and Mineral Resources (ESDM) plan, both targeting a total of 175 MW.

ESDM target year

Cumulative planned capacity

The years shown are commercial-operation (COD) targets under the ESDM plan, not guaranteed start dates. Delivery depends on resource confirmation, permits, financing, construction and definitive agreements. The final 110 MW comprises two 55 MW units; the capacities shown are not current operating capacity.

PROJECT GEOGRAPHY

The Bedugul project area

Two source maps show the wider geothermal working area, the Bali Energy contract area and the locations of wells. Each map retains its original boundaries and legend.

Brightness adjusted for readability. Boundaries, well markers, roads and text retain their original positions and content.

Maps reflect their source dates. A working area or contract boundary does not mean that the entire area will be developed. Candidate wells indicate proposed locations in the source, not completed wells.

A resource studied.
An opportunity to develop.

Seven source documents trace Bedugul’s resource assessments, engineering studies and field assets. They are listed from the earliest confirmed study or publication date; the undated collection is shown separately at the end.

Read the figures in context.

The studies use different areas, methods and assumptions. Their numbers are not additive and do not show a time trend. Resource potential, the 175 MW development concept and current well output are different measures.

The research record

MWe denotes electrical megawatts. Dates distinguish field surveys, appraisals, report issues and paper publications; unknown days are not inferred. The undated collection is listed separately at the end. Organisation groups describe source roles, not corporate ownership or current endorsement.

PROJECT HISTORY

Decades of work.
A tangible foundation.

Bedugul’s exploration programme has included geophysical surveys, six temperature-gradient holes and three full-size wells. International technical studies have helped build an understanding of the field.

The next stage is to reassess and develop this foundation through updated technical work and a phased investment programme.

Developing energy.
Respecting place.

Bali’s future is inseparable from its environment, communities and culture. These considerations belong at the heart of project development.

I.

Technical discipline

Progress through resource assessment, engineering and staged development, with each step informed by evidence.

II.

Respect for Bali

Recognise the importance of the highlands, local communities and Bali’s religious and cultural traditions in project planning.

III.

Long-term collaboration

Engage with public institutions, technical specialists and prospective partners around a responsible development pathway.

A CLOSER LOOK

Understanding Bedugul.

Is the project generating electricity today?

Bedugul is presented here as a development project. The 175 MW figure is the overall development concept, not a statement of current installed capacity or commercial operation.

Why develop in stages?

A staged approach allows technical information from earlier work to inform later investment decisions. The stages are shown as 5–10 MW, a further 55–60 MW, then 110 MW. The original plan is 10 + 55 + 110 MW; the ESDM plan is 5 + 60 + 110 MW, with COD targets of 2028, 2030 and 2033 respectively. Both plans total 175 MW.
