INDONESIA’S ENERGY CONTEXT
• The West part (Sumatra, Java-Bali,
Kalimantan, Sulawesi) represents 80 to 90 %
of the country energy demand
• the East consists of small to medium sized grids,
mostly relies on diesel power plants.
• Challenges for coal and gas
• High power production costs (BPP)
• Intermittent power brings unseen costs and
operation challenges.
• Difficulties in implementing diesel replacement
program
• Large grid relies on coal and gas resources to
provide affordable power to the population;
IPPs of geothermal, hydro, and wind focus
here.

6. C o n f i d e n t i a l - P r o p e r t y o f H D F E n e r g y
• Mainly use diesel power plant, viable option in
small and medium grids, yet with operational
challenges and GHG emission intensive
• Gas and coal are not economically feasible for
small-medium size/island grids
• VRE (Solar & Wind Power) introduction to the
grid:
– Could not serve as a baseload
– Intermittency effect leads to power
curtailment
– Usually needs additional load follower
(thermal power plan) to accompany the VRE

• With Renewstable Power Plant
• Serves as a Renewable® baseload power plant
• Capacity factor > 80%
• Intermittency is handled within Renewstable®
power plant, therefore utility receives firm
and stable power

INDONESIA’s
POTENTIAL on
RENEWSTABLE®
APPLICATION
▪ Firm, stable, dispatchable power at high availability
▪ Suitable for islands, small & medium sized grids
▪ Provides potential to reduce GHG emissions and
decarbonize power sector in Eastern Indonesia.
▪ Supports grid stability in the island setting
▪ Reduce dependency to fossil fuel (dedieselisation)
▪ Strong potential for replicability, thus > 20 potential

CONCLUSION
C o n f i d e n t i a l – C a n n o t b e d i s c l o s e d w i t h o u t H D F ’ s a p p r o v a l
• Hydrogen as energy storage is a new topic, this requires
continued awareness building and coordination with the
key stakeholders.
• Hydrogen road map or mention on the energy regulation
could promote development of hydrogen ecosystem in
the country
• Stable clean power to support economic development in
areas that have geography challenges to connect to the
main grid.
• Countries have potential to produce hydrogen, but
hydrogen application and its sector coupling need to be
adjusted to each country context.
