The National Energy Plan (RUEN) contains a strategy to accelerate the use of solar energy with the obligation to use a minimum of 30% of the roof area of ​​government buildings and 2% of the roof area of ​​luxury houses for solar PV. This mandatory requirement can boost the utilization of solar energy, as well as open the market for solar energy generation technology. In the regional expanse, the Regional Energy General Plan (RUED) as the interpretation of RUEN, is expected to encourage the achievement of renewable energy targets according to the needs and potential of each region.

IESR calculates the technical potential of buildings in Central Java for the adoption of solar rooftops. The complete result of the finding is available in the publication of “Powering The Cities: The Technical Potential of Roof PLTS in Government Buildings in Central Java.”
