Alfian, The Jakarta Post, Jakarta The government has said geothermal power will contribute 30 percent to its 10,000 megawatts (MW) electricity program, but investment in the clean energy source is being threatened by an unexpected pricing plan. The first geothermal energy projects will be made available to investors in 2009. Private investors developing geothermal sites in Indonesia must sell all electricity produced to state power firm PT PLN.
