Electricity sector overview The Malaysian Government established the Energy Commission on 1 January 2002, under the Energy Commission Act 2001. It assumed all responsibilities of the Department of Electricity and Gas Supply which was dissolved on the same date. The main utilities are Tenaga National Berhad (TNB), the Sarawak Electricity Supply Company (SESCO) and Sabah Electricity Limited (SESB), each covering the region of Peninsular Malaysia, Sarawak and Sabah respectively and all having the Government as its main shareholder. In all three regions there are also independent power producers (IPPs) supplying some portion of the electricity to the utilities.

The use of distributed power generation technologies such as solar hybrid power generation or micro hydro-electricity to provide access to electricity is greatly viable in Malaysia. These solutions have been applied in approximately 17 per cent of the new connections from 2010 to 2012.
3 The target is to supply five times
as many houses with electricity as compared to the 2006-2008 timeframe. In 2010, the total installed capacity of TNB and IPP in Peninsular Malaysia remains at 7,040 MW and 14,777 MW respectively. Total electricity generation in 2010 was 125,045 GWh, dominated by natural gas and coal:

Small hydropower sector overview and potential As of 2012, there are 58 mini-scale hydropower stations in Malaysia. TNB Energy Services Sdn Bhd (TNB-ES), a wholly owned subsidiary of Tenaga Nasional Berhad (TNB), has been operating and maintaining 30 mini hydro stations throughout the peninsular with a total installed capacity of approximately 16 MW.
5 Small hydropower has yet to
be fully developed. With hilly topography from south to north, east to west and an abundant number of streams flowing to foothills, Malaysia has considerable small hydropower potential.

A total of 149 sites with an estimated micro hydropower potential of 28.9 MW have been identified (figure 2).
6 There are some 150 river
systems in Peninsular Malaysia and about 50 river systems in Sabah and Sarawak. It is also predicted that by the year 2020, most rivers and waterways will be fully utilized especially for the generation of electricity. Access to water and the use, control and diversion of water flows is subject to federal and state regulation. Other regulations apply to any physical alteration of a stream channel or bank that may affect water quality or wildlife habitat. Renewable energy policy The Energy Commission, also a government monitoring agency of national renewable energy development, has set a target of 5.5 per cent for electricity from renewable energies. This was made achievable through the establishment of the Sustainable Energy Development Authority, formed as a statutory body under the Sustainable Energy Development Authority Act 726 in 2011.
In 2009, the authority developed the National Renewable Energy Policy and Action Plan aimed at harnessing renewable resources. The document outlines five objectives comprising elements of energy, industry and environment:
7
1. To increase renewable energy contribution in the national power generation mix. 2. To facilitate the growth of the renewable energy industry. 3. To ensure reasonable renewable energy generation costs.

4. To conserve the environment for future generations. 5. To enhance awareness on the role and importance of renewable energy. The 8
th (2001-2005) and 9
th (2006-2010) Malaysia
Plans introduced several programmes such as the Small Renewable Energy Programme, the Biogen Full Scale Model demonstration project and the MBIPV programme. Mini-hydro (87.7 MW), biomass (using palm oil empty fruit bunches), biogas (from palm oil mills effluent) and municipal solid waste are among the most popular technologies for renewable energy in Malaysia.

Barriers to small hydropower development
Bureaucracy issues and problems, institutional and regulatory complexity and inconsistency, i.e. with regards to land acquisition.
Full small hydropower development is constrained by localized water shortages particularly during drought periods, pollution in more than half of Malaysia’s rivers, and climate change effects.
Cost of capital for small hydropower ishigher than those for conventional power plants.
9 Utilizing
locally manufactured components combined with an appropriate operation strategy will alternatively reduce the project costs.
10
Access to finance at competitive rates is difficult. Financial institutions are unfamiliar with the small hydropower technology and therefore not as open as towards other technologies.
Siltation and high sedimentation.
Public perception that renewable energy, including small hydropower, is still experimental.
