Electricity

 

The cost and reliability of electricity is also recognized by Government as a major factor for profitability and smooth business operations, especially in energy intensive industries such as mining and manufacturing. A combination of Government and private sector initiatives suggests that measurable improvements in the supply and distribution of electricity could nevertheless be achieved in the near future. Several larger businesses have recently set-up operations to generate their own power facilitated through various incentives offered by Government. This will help to reduce pressure on the grid. A roadmap has also been drawn up for the re-introduction of private participation in GPL to help improve its operating efficiency. The Unserved Areas Electrification Programme is expected to link at least 30,000 additional households in 200 under-served and unserved communities to the electricity grid. As part of Guysuco’s Skeldon Modernization Project, a new co-generation plant is also expected to contribute 10 MW of power to the national grid. Moreover, in March 2005, Omai Services Inc. (OSI), whose diesel plant has an installed capacity of 12 MW, was granted a license to supply electricity to the Linden Electricity Company.

While these developments in the energy sector will have a positive short-term impact, the most promising option is the development of Guyana’s hydropower potential. In this regard, negotiations are currently ongoing to develop a 100 MW scheme at Amaila Falls in western Guyana. In other alternative energy plans, the Guyana Energy Authority is other means of alternative energy.

 

Hydro-Power in Guyana

The following is a summary of 67 potential hydropower sites in Guyana:

Eclipse Falls, Region 1

Studies have estimated the potential capacity at Eclipse Falls as 4 MW. All data relating to this site is currently being updated under the Unserved Areas Electrification Program.
