Business assessment for

diesel hybrid systems in Indonesia

Stephan Blocks, EKONID –– Berlin, 3st June 2013

I. Introduction: Review 2012 and outlook 2013-2014

2012

Business delegation on PV systems, open for all kinds of technology (on- and off-grid)

2013

Focus on PV hybrid systems for the off-grid market

2014 or 2015

AHK business trip in 2014 or 2015 especially for on-grid solutions

I. Introduction: Framework of the AHK market

study

Update of the previous study with focus

on the PV hyrbid market (off-grid)

Serves as handbook for businesses

Focus on Indonesian actors and their

demand

Available latest end of July 2013

II. Sentiment for PV hybrid solutions in Indonesia

High energy production cost for diesel gen-sets (30 Euro cent)

Competetiveness of PV solutions is increasing

Electricity demand increases by 9% annually

Electrification rate in average only 74 %

Necessity of decentralized grids to electrify remote areas

Awareness for PV solutions increasing

III. The market for PV hybrid solutions

Indonesian ministries, local authorities:

Estimated budget for PV projects in 2013: USD 250 million

80% for off-grid solutions thereof

PLN

implements government as well as its own projects

Base transceiver stations

of telecommunication companies (2 MW installed capacity, estimated)

Captive power solutions

7

III. The market for PV hybrid solutions: PLN/GOI

Besides the 8 large interconnected grids PLN operates

600 (mostly diesel powered) mini-grids outside the Java-

Bali network

PLN operates a total of 4600 diesel gensets (3,100 MW)

outside Java-Bali, representing 40 percent of the total

outer Java-Bali generation capacity

Estimation: 30,000 small diesel gensets in rural areas

Region Estimated Budget Tender period

Papua province (6 tenders)

600K – 2.0 million Euros 28/05 – 05/06/2013 and 31/05 - 10/06/2013

West Papua province (2 tenders)

> 1.0 million Euros 28/05 – 10/06/2013 and 31/05 - 10/06/2013

South Jakarta (on-grid?) 40K Euros 28/05 – 10/06/2013

Karimunjava island (East Java)

27K Euros 28/05 – 10/06/2013





1000 islands project:

Phase I to start in 2014: hybridization of diesel gen-sets with PV

~35 MWp scattered across 170 locations

mini-feasibility studies already conducted for all sites

300 Mio US$ in loans from World Bank and KfW

tender to be announced internationally in 2014

High-quality components to ensure sustainability

opportunities for international participants

B) Base transceiver stations (BTS)

5-10 % of Indonesia’s 150,000 to 200,000 BTS are off-grid and

usually powered by diesel gen-sets

Operators aim at cost reduction for power supply to increase

margins

PV hybridization starts to be a cost-efficient alternative

System size 5-20 kWp

Telkomsel has experience with PV solutions since 2003

15


Telkomsel:

In 2007-2008: Conergy in partnership with Gerbang Multindo Nusantara (GMN)

16 off-grid photovoltaic systems for PT Telkomsel

total installed capacity of 158.50 kw

Project sites were located in remote areas around Sumatra, Sulawesi and Irian Jaya (Papua)

Status 2012:

Telkomsel operats 234 “green” BTS powered by solar cells and micro hydro power as green energy sources

16


Indosat:

Employs a hybrid system: combination of

solar cell panels, wind turbine and bio-fueled diesel gen-sets and

(where applicable) electricity from the PLN grid to supply power to a BTS

Experiences with Charge-Discharge-Controller (CDC), battery bank+diesel gen-set (760 sites in 2011)

Status 2012: more than 100 solar-powered BTS in remote areas to reduce reliance on diesel

17


C) Captive Power

According to PLN data:

6.4 GW of captive power installations (4 GW outside Java-Bali)

Diesel gen-sets are mostly used in off-grid areas for tourism, industry and residencies

no mass market yet as customers have to be convinced individually

Eco resorts and manufacturing plants that want to be seen as “green” provide a steady and increasing market for PV hybrid solutions

18

IV. Challenges

Tender and business processes not always transparent

Import duties and local standards for technical

components

Lack of expertise

On-site problems

19

V. Recommendations

Partnerships with experienced local contractors and distributors

Quick and reliable after-sale-services are a must

Durable technology for energy storage and control electronics

Ability to co-finance projects is an advantage

Successful pilot project leads to more opportunities

Community development in the project regions, including capacity

building for local stakeholders
