STELCO History• The State Electric Company Limited (STELCO) is an entirely State owned organization

responsible for the generation and distribution and sale of electricity to consumers through out the North Central Province (NCP) of the Republic of Maldives.

• STELCO was formed back in 1949, as a government department - Electricity Department. The service started with the use of a 14kW generator providing electricity to only 50 consumers of Male’.

• Over the 63 years of service, the institution was re-named from Electricity Department to Maldives Electricity Board (MEB) and then on 19 June 1997 the name was changed to State Electric Company Limited (STELCO) as a totally state owned company by a Presidential Decree.

• By end of 2008 STELCO expanded services from North to South of the country totaling 28 islands catering 60% of the total population of Maldives.

6

STELCO Today• In 2009 with the new government policies, 7 provinces were

formed with utility companies managing all utility services in their own respective provinces. As a result, on 1st May 2009 STELCO handed over 22 island power houses to these utility companies.

• STELCO now provide its services to 28 islands in NCP with over

33000 consumers and total installed capacity of 78.38MW covering 37% of the population of Maldives.

• Diesel power plants are mainly used in STELCO

• 1 MW of Solar PV installed in Male’ and few other islands under various projects.

Male’• Current peak demand in Male’ is 41MW• Total Installed capacity is 61.42MW

Challenges in Expansion & the Need for a Grid

• Male’ is congested• Land Availability

• No available space in Male’.• Exhaust Emission Limitations

• When the current power project is completed power plant emission will reach to maximum acceptable limit

• Power System Protection• Will reach maximum allowable production capacity based on

system Voltage (appx.55MW)• Network Overloading

• Male’ 11kV distribution network requires upgrades and expansion Power Generation outside capital island Male’??

10

Potential Future Locations• Hulhumale

• Land is available• Future load center• Minimal distance (economically more viable)

• Thilafushi• Land is available• Future load center (commercial activities)• Long distance

13

Island Electrification

• Average size of each island is small• Population less than 1000 on average• Power demand is low• Cost of operation very high• Revenue is small• Operational loss

14

Regional Interconnection Grids• Improves reliability and system efficiency

• Phase 1: Interconnect islands in the same reef– More than 2 islands in the same reef– These power systems can be interconnected– Consider possibility of having larger power plants

• Phase 2: Interconnect islands across 2 or more reefs within the atoll.

• Phase 3: Interconnect the grids across atolls.

Carbon Neutral Maldives

• Until 2012, all our energy production is from diesel (MGO)

• GoM has announced to be carbon neutral by 2020

• GoM is committed to produce energy from renewable sources

• Solar and wind seems the most favorable to Maldives

17

Challenges for Renewable Investments• Financial & economic barriers

– Initial investment large– Difficulty in getting finance/loans due to high risk of projects– Payback period long

• Availability of space for installations– Male’

• Small or No roof tops• Cannot get big space in one area• Installations Outside Male’

– For islands– Space may be available in some islands but still limited in many islands– Nearby offshore options available

Expansion of RE investments at commercial scale also requires an interconnected grid

RE Challenges …

• Limitations on the level of RE injection– Small & Independent Grids– Limitation on direct feed RE systems– Requires larger grids

• Submarine cable

• Technical– Uncertainty in technologies– Limited Expertise

• Institutional & Regulatory– Need a framework to encourage RE technologies

23

Challenges …

• Submarine cable very expensive– Male’-Hulhumale’: Estimated US$26.4 million– Male’-Villingilli: Estimated US$10.9 million– Villingilli-Thilafushi: Estimated US$26 million

National & Regional Grid

• Currently each island is an independent power grid– National grid will remove this disadvantage

• Financial & Technical difficulties due the unique geographic nature of the Maldives

• Maldives can take benefit of the energy grid– Eliminates the constraints on power expansions– Help to reduce the price of electricity– Increase stability & efficiency– Land issue will also be solved

Summary

• For Male’, demand continues to grow at a very fast rate

• Having challenges in power expansion• Further challenges in RE investments• Power expansion limited by the need for a Grid• Constraints on Grid interconnections due to financial

and economic issues• A regional grid will give a lot of advantage for the

case of Maldives
