Energy Policy

• Achieve complete electrification through grid and off‐grid schemes by 2012

• To reach a 10% of electricity from renewable energy resources by 2015

• Exploit the full economic potential of energy efficiency improvement

• To enhance the investment climate in all indigenous  energy resources

• Adopt an integrated planning approach encompassing all above towards a sustainable energy future

The Small Power Development Program of Sri Lanka: The 

Success Story 

Off‐grid component

300 village community networks, based on small hydro (typical capacity 

range 10‐100 kW, covers 5000 households in total)

129,000 solar home systems in operation

Now serves about 2% of households in the country

On‐grid component

Over 90 small power plants in operation (small hydro, wind)

Many more under construction, approvals pending

Large enthusiasm among developers, investors

SPP(Standardized Power Purchase)  

route for Small Power Projects: The 

success story

Operational since 1996, had a major policy review in 2007

Open for developers of capacity up to 10 

MW

Over ninety  projects now in operation, dozens more in various stages of development

Provided 6.6% of grid generation in year 2010 (target: 10% by 2015)

BasicsNon‐negotiable, paid in LKR

Paid on the basis of energy delivered (not based on capacity)

AgreementsOnce signed, no change in tariffs for 20 years (except the smaller O&M escalation element)

Cost‐based, technology‐specific

Tiered or Flat (levelised); option to developer at the time of signing the Agreement

Provides comfort to lenders and return on equity to developer from day 1 of operation.

Solar Potential in Sri Lanka 

Applications

• Off‐grid electricity

Solar Home Systems

• Grid Electricity

Net Metering

Solar Energy Parks 

• Solar hybrid systems 

Remote Island Electrification

Off‐grid Potential 

129,600 solar home systems lighting up rural homes

More than 300 operational village hydro sites serving more than 7000 families by end 2010

Off‐grid electrification seems to be a matter of declining interest

Net Metering

• Facilitate import and export of  electricity through   

bi‐directional metering

• Customers can bank the excess electricity generated and 

trade the same against future consumption (period of  

banking 10 years)

• All consumer categories are eligible (Industrial,  

Residential, General purpose, Religious)

Grid Potential

Solar radiation over the island does not show a marked seasonal variation, though significant spatial differentiation could be observed between the lowlands and mountain regions.

As estimated in the solar resource map developed by the NationalRenewable Energy Laboratory (NREL) of the USA, over most parts of the flat dry zone, which accounts for two‐thirds of the land area, solar radiation varies from 4.5 – 6.0 kWh/m2/day. 

Thus, a substantial potential exists in the dry zone of Sri Lanka for harnessing solar energy

Grid Tied Projects

•Two projects (500kW and 737kW) in the  

same location

•Funded by Japanese and Korean Governments

• First hand experience for local Engineers•First phase completed early May 2011

•500kW capacity yielding  more than 2,500kWh per day
