Rural Electrification Mandate

4 Stages Developments of Rural Electricification1 Iniittiial Stage

During 1958-1975

1958 NEA (Later DEDE)

established

By 1960 only 2% of

villages electrified

1960 PEA established

with mandate toelectrify rural areas

water flows, lights

shine, good road

PEA implemented 3

Rural Electrification

Projects by

supplying from small

diesel power plants.

About 10,000 villages

(20%) had been

electrified.

NEA focused on

Hydropower

2 Accelerated Rural

Program Stage During

1976-1996

PEA expanded

implementation by Grid-

Connected System.

After PEA Implemented

the Accelerated Program,

the

number of Electrification

Village increase as follow :

1981 : 22,525 Villages

( 44%)

1986 : 41,374 Villages

( 75%)

1991 : 58,334 Villages

( 95%)

1996 : 64,228 Villages

( 98%)

3. Rural Household Electrification

Stage 1997-2003

3.1 1st Stage (1997-1999)

Covered 400,000 households

Total investment 9,620 M.

Implemented by Grid System

3.2 Project 2nd Stage (2001-

2003)

Covered 150,000 households

Total investment 3,655 M.

Implemented by Grid System

3.3 Submarine Cable to Island

started

3.4 By 1999 only 1% non-

electrified village

4. Rural HouseholdElectrification Stage by

Solar Home System (SHS)

2003-2010

290,716 households

without grid connection

before SHS

188,995 SHS installed

Thailands installed PV

capacity in 2003: 6 MWp

SHS program adds 23

MWp!

After SHS installed, the

responsibility of O&M SHS

transferred from the PEA

to Tambon (local)

governments

Case Study : Mae Hong Son (MHS)


14/19

Geography

Most of the MHS of areas aremountains and forests.

WeaknessesHighlights- Many Hydro sources

- Many natural attraction

- The Travel to villages is difficult, esp. in

raining seasons.

- Limited good agriculture area.

- Some village live on watershed area

(Sensitive area class 1 A)

MHS electricity situation

Using electricity system 25 from 41 villages by PEA

1. Household- Approx 1,713 SHS- Solar PV Mini-grid 2 system- Hydro power 58 kw

2. Local Schools- Solar PV power system 1.5-6 kw- Solar PV 6 kw

3. Local Hospitals- Solar PV 1.5 kw and 6 kw

Sample for target areas

Tambon Mokjumpae

- Hydro power for household- The Repair photovoltaic battery

charging stations (PV BCS)- The charcoal chaff briquettes

Tambon Maeyuam, Ampore Mae-sarieng- The Repair photovoltaic battery

charging stations (PV BCS)- Reduce firewood as replace by

using fuel-chaff for cooking

Tambon Tamrod, Ampoe Pangmapha

- Reduce firewood as replace by

using fuel-chaff for cooking- Biogas for household- Solar power 2.18 kWp

Tambon Maesuad, Ampoe Sob-moei- Hydro power for household & school- Biogas for school- The Repair photovoltaic battery

charging stations (PV BCS)- Solar PV power 2.18 kWp


17/19

Key success factors

RE Potentials are plentiful

State Budget is ready for Community

Direct Benefit to community provided

Cooperation with local organizations and

private sector

- Cooperation with local communities for

action plan

- Project development & allocation of

budget for O&M

- Interests from many private sectors for

CSR projects

Strong local community participation


18/19

Many achievements on Rural Electrification inThailand should be noted.

99+% electrification rate

PEA and DEDE are key driving forces

By integrating Renewable Energyenabling

new policy platforms

Hybrid RE system Community-scaled focus

Smart + Local Grids Technology

Sustainable & Green Energy Access

for All
