| While it is recognised that the Amaila Falls Hydro Electric project is vital to Guyana,Boston Celtics Jerseys, the first decade of its existence may prove to be costly and may require financial assistance from the government.The Government of Guyana had approached Kaehne Consulting Limited to review a proposal that was submitted by Synergy Holdings Inc. and Harza International Development Company to provide an assessment of whether the project is technically, economically,Carlton Fisk Jersey, environmentally and financially viable.In that 2002 report by the Canadian consultants it was pointed out that the energy market which the developers plan to capture appears to have been overstated in the early years of the project.It was stated that the Omai Gold Mine, to which it was proposed to sell an initial 223 GWhrs of secondary energy annually (decreasing to 63 GWhrs per year by 2011), will be closed by the time the project is operating unless the results of ongoing exploration are positive.The Linden load was found to be significantly smaller than the amount envisaged; currently (2002) about six MW rather than the 15 MW assumed in the Feasibility Study Report.This was found to translate to an available annual energy market of about 50 GWhrs in 2007.This compares with an estimated annual market of 114 GWhrs assumed in the Feasibility Study Report.It was pointed out that Amaila Falls (or a similar hydro project) will be built sooner or later and for the project to succeed it must have a reliable and accurately defined water supply, an accurate estimate of total development costs and operating costs, a proven design and a sustainable energy market.At that time it was found that with the available load scenario, it is unlikely that the project will be able to sell 100 per cent of its planned annual output until about 2016 and it is possible that Government assistance will be needed to make up this revenue the revenue shortfall.That load market has since been depleted.Subsequent to that review, several large companies such as Demerara Distillers Limited and Banks DIH switched to self generation and are off of the energy market that was supposed to have gone to the Amaila Falls Hydro Electric Project.It must further be pointed out that at that time the proposal was for a 100MW plant and not the 150MW plant that is now proposed to be built by Sithe Global.It was pointed out in the report that the developers must confirm the energy markets available to the project, given that it will be a dynamic situation but will determine the net cost of supply from Amaila over time.The Amaila Falls Project that was proposed consisted of a reservoir of approximately 180 million cubic metres capacity, two dams of maximum height 30.5 metres,China Jerseys, a water conductor consisting of an underground tunnel,NFL Jerseys Wholesale, a vertical surge shaft and surface penstock to a powerhouse containing four 25 MW Francis hydraulic turbines and electric generators and a tail race for water discharge back to the Kuribrong River.The power generated was to be fed to a nearby substation and subsequently via a 296 km double circuit 230 kV overhead transmission line to connect to the existing GPL system at Sophia Substation.“Other proposed or possible connections are to the future Tumatumari hydroelectric project (45 MW), the Omai gold mine and the Linden region including Linden Mining Enterprise Limited (Linmine), the bauxite operation at Linden… The project would be accessed by a new road from Pamela Landing, approximately 40.6 km in length…An airstrip is also planned for the site.”That project basically anticipated supplying energy to three main customers, namely Guyana Power & Light (GPL), Linden Power Company (LPC) and Gold Mines Limited (Omai).“The Feasibility Study Report envisages initially delivering approximately 438 GWhrs of firm energy annually to GPL,Custom Boston Celtics Jerseys, 114 GWhrs of “firm” energy to Linden Power Company and 223 GWhrs of secondary or non-firm energy to Omai.”It was found that as an Independent Power Producer (IPP) with one major customer (GPL – the Linden load accounts for only about 10% of the GPL load), Amaila will strive to sell all its available output to that customer.Kaehne Consulting Ltd. (KCL) is a Canadian electrical engineering and project management firm based in Vancouver, British Columbia. Together with its predecessor firm, J. Kaehne & Associates Ltd., KCL has been involved in a wide range of industrial projects internationally since 1986.The majority of completed projects involve mining or power generation, and in many cases,Wholesale China Jerseys, both. A typical project includes conceptual planning, budgeting and scheduling, equipment specification and selection, basic and detailed design, contract preparation and negotiation, construction supervision, site commissioning and operator training. |
