Govt eyes solar, microhydro power plants

The Jakarta Post, Jakarta

The government is planning to build thousands of small scale solar power units as well as microhydro plants on eastern islands of the nation next year to increase electricity penetration in some of the country's more remote areas.

The government will build 15,000 household solar power units, each with a capacity of 100 watts, the Ministry of Energy and Mineral Resources' director general of electricity and energy Yogo Pratomo was quoted by Antara news agency as saying over the weekend.

"We hope the (small-scale) power units will meet electricity demand in remote areas in the eastern part of Indonesia," he said.

Each of the solar cell units will cost between Rp 5 million (US$500) and Rp 6 million to build. "However, they won't use any fuel except sunlight so there is no extra expense," said Yogo.

Aside from utilizing sunlight, the government also plans to build 200 microhydro power plants with a capacity of between 50 kiloWatts (kW) and 500 kW each. Investment needed for every kiloWatt is estimated at Rp 20 million.

"The funds to construct these plants will be taken from the state budget and (state power firm) PT Perusahaan Listrik Negara (PLN)," Yogo was quoted as saying.

The development of power capacity in the country has been hampered due to a lack of funds since the monetary crisis severely hit the country in 1997, despite the steadily rising demand.

PLN is focusing its expansion on Java -- where more than half of the country's population lives and an estimated 70 percent of the country's economic activity is located -- Bali and Sumatra. The state firm has allocated just 17 percent of its projects for other islands.

The latest data from the World Bank shows that the electrification ratio in Java reaches 72 percent, while that in Maluku is limited to 50 percent. Only one in five people enjoy the luxury of electricity in natural resource-rich Papua, Indonesia's least-developed province.

Despite massive potential, power plants using renewable energy sources contribute only a small portion of the country's total installed power capacity of about 25,000 megaWatts (MW).

The installed capacity of mini and micro hydropower plants is only 54 MW, while those utilizing geothermal and biomass energy have installed capacity of 800 MW and 302 MW, respectively.

The government aims to raise the use of new and renewable energy sources in power generation from 0.2 percent currently to 4 percent by 2020.
