Interconnected Systems

• Two of main islands have own interconnected systems
• The rests are:
– Clusters of service areas with main grids, including remote off-grid distributed systems (Kalimantan,
Sulawesi, Papua)
– Small islands: clusters of grids mainly of diesel systems, off-grid distributed systems

• ALL power plants use foreign technology.
• BPPT is appointed by the Government to develop national technology, in
cooperation with local industries.

1. Overlapping between geothermal working areas and
protection/conservation forest  at least 30% of
geothermal resources are located in the conservation
forest.
2. Lack of exploration data  bidding by the goverment only
provides geological, geophysical and geochemical data.
3. Price of geothermal energy is not competitif  insufficient
fiscal policy, limited funding & incentive mechanism, high
investment cost, very high technical risk.
4. Geothermal market is very narrow  PLN as a Single
Buyer.
5. Uncertainty in the legal aspect.
6. Lack of human resources.
7. Social problems.

1. TECHNICAL RISK:
• Resource risk  possibility of not finding sufficient geothermal
resources for commercial use.
• Operational risk  drilling success ratio, well productivity.
• Technological risk.
• Construction risk  land acquisition for steam field and power
plant.
2. NON-TECHNICAL RISK:
• Market access and price risk  market/price fluctuation.
• Legal and regulatory risk  the certainty of government policy
and regulation.
• Exchange rate and inflation risk.

1. Improving and harmonizing regulations in
geothermal business, including a revision of the
Geothermal Law to allow the geothermal
development in conservation forest.
2. Pricing regulation with comprehensive
treatment.
3. Fiscal incentives for geothermal development.

*) Equipment :
Equipment consists of steam turbine, boiler, generator, electrical, instrument and
control, balance of plant and/or civil and steel structure.
**) Service :
Consultancy service (feasibility study), integrated construction service (engineering,
procurement, and construction), inspection, test, certification and/or supporting
services.

1.

It is a national priority program stated in the Presidential Regulation
No. 05/2010 regarding the National Medium-Term Development Plan
2010 – 2014.

2.

Output :
a) Condensing Turbine Technology of 3 MW GeoPP.
 Ready for operation in Kamojang Geothermal Field
b) Binary Cycle Technology of 100 kW GeoPP.
 Under construction in Wayang Windu Field

TARGET
1. To substitute the use of fossil fuel based diesel power generations.
2. To accelerate the development small scale geothermal power
plants by domestic human resources and national industries.

• With the geographical condition as an archipelago, the use of
solar power generation is estimated to be the right solution to
achieve the target of 93% electrification by 2025.
• The Government has issued a blueprint for a national energy
management, which in 2025 could be achieved using
renewable energy in National Energy Mix up to 17 %.
• Government planed for accelerated development of solar
power generation, targeted to be installed until 2025 up to
2,2 GWp.

• Based on temporary projection of energy utilization 2010
shows petroleum 43, 9 %, coal 30, 7 % and natural gas 21 %.
Renewable energy contribution is still low for about 4, 4 %.
• Installed capacity of solar power plants in rural areas are
estimated around 17 MWp
• State Electricity Company plans to build 1000 solar power
generation for isolated island in Indonesia. The construction
will be started on 2012 and is expected to be completed
within 5 years

LEMBAGA ILMU PENGETAHUAN INDONESIA

• Indonesia solar energy potential is very large, with average
daily radiation 4.8 kWh/m2/day.
• In eastern part of Indonesia, average daily radiation of
about 5.1 kWh/m2/day. with a monthly variation of about 9
%.
• While in western part of Indonesia, average daily radiation of
about 5.1 kWh/m2/day. with a monthly variation of about
10 %.

1. Institutional policies: regulations,
standards, systemsmanagement, education.
2. Diversification policy photovoltaic applications: utilization as
electricity in rural areas, encouraging the use
of PV in luxuryresidential and commercial buildings
3. Incentive mechanism
4. PV industrial development
5. R & D and mastery of PV technology
6. investment policy

• Smart interconnection
grids

– Improved reliability
– Energy savings
– Robustness of operation
and control (Self-Heals)
– Etc.

• Smart microgrids with
distributed energy
resources (DER) where
applicable

– Distribution systems
containing high DER
penetration may require
considerable operational
control capabilities.

Paradigm Shift in Energy System
Increasing penetration of renewable energy, diversification in electricity
generations, reduction in carbon emission, etc.
Future Chalenges
• Enhanced compatibility of electricity network with increased penetration of
renewable energy
• Communications between the network and various types of generations
• Providi g services for various co su ers’ electricity eeds, ai ly i re ote
and isolated areas

A key solution
Smart MicroGrid could efficiently control integration of renewable energy to
the main grid.
