NEW & RENEWABLE ENERGY DIVISION OF PT PLN (Persero)

• It is under the Corporate Planning Directorate • Main task covers the development of new and renewable

energy, either by PLN or Independent Power Producer (IPP). • There are 3 sub-divisions:

a. Hydro b. Geothermal c. Alternative (Biomass, Wind, Solar PV, Ocean, Nuclear,

Coal Slurry, Hydrogen, etc.)

1. President regulation No. 4/2010 instructed PLN to

accelerate the RE development

2. GOI has set a goal that 23 % of national energy

mixed in 2025 shall come from RE

3. GOI set a target to increase electrification ratio 99,5

% by 2025

4. GOI introduced Feed in Tariff for small RE ≤ 10 MW

5. PLN is obliged to purchase the electricity from RE

power generation (take and pay)

POLICY AND TARGET

PLN EXPERIENCE(S) IN

OFF-GRID DEVELOPMENT

INTRODUCTION

BACKGROUND:

• The major domination of diesel generator in remote islands.

• Cost of electricity fuel/diesel based is expensive .

• Challenge in fuel supply (transportation)

GOALS:

• Reduce the diesel consumption

• Increase the ratio of electrification

• Increase the development of new and renewable energy.

• Reduce the cost of electricity.

CONSIDERATIONS

MAIN PRIORITY FOR REGIONS WITH:

• High diesel/fuel consumption

• Remote or isolated areas / islands

• Expensive cost of electricity production

• Limited alternative of energy sources to produce electricity

• No electricity access whatsoever

• Limited availability of electricity (up to 12 hours per day)

STRATEGY

STRATEGY:

• Work with local government in land relinquishment

• Prioritize the use of Diesel – Solar PV Hybrid by using the existing diesel

engine

• Options of either on-grid connection, off-grid, or hybrid depending on the

existing grid on the site

• Limit the penetration of intermittent sources (PV, Wind, etc.) up to 20% of

daytime peak load (especially for on-grid)

• Provide electricity of up to 12 hours in areas where no access to electricity

• Increase the electricity availability for up to 24 hours in area where electricity

access is limited

• Open for IPP scheme or assigned by EBTKE

EXAMPLE: PLTS AIR MAMA, ALOR

PROJECT:

- Name : PLTS Air Mama

- Capacity: 125 kWp

- Population: 190.026 people ( ±500 residentials)

- Average Sun Irradiation : 5,63 kWh/m2/day

Latar Belakang:

Desa Air Mama has yet no electricity access. Nearest PLTD is in Baranusa with

operational hours up to 12 hours. The closest diesel supply (Pertamina’s depot) is ± 125

km away in Kalabahi with transportation cost Rp. 780 /litre by motor boat (total fuel tank

storage of 20.000 litre). PLTS Air Mama will be connected to distribution lines of MV 20

kV and LV 220 V of ±10 kmc and ±12 kmc, respectively). This scheme will increase the

electricity supply for up to 24 hours.

1. The potential of RE development in Indonesia is

challenging and promising, therefore Indonesia is

attractive for RE industries

2. PV Development is aimed to increase the

electrification ratio and to reduce the diesel fuel

consumption in remote areas/island
