Aquarius Hydroelectric Project (A small-scale CDM project) Project Design Document

Host country requirements: Brazil is a non-Annex 1 country Brazil has ratified the Kyoto Protocol last August 28, 2002 Establishment of Designated National Authority

A.1. Title of the project activity: Aquarius hydroelectric project

A.2 Description of the project activity:  The objective of the project activity is to generate clean electricity using hydroelectric resources and sell it to the regional power grid.  The project is expected to have an installed capacity of 4.2 MW, and will utilize the water of the Correntes river. It will be a run- of-river project with no dam or flooding.  The Aquarius project started in the 1980s with some structures already in place, like, water intake channel, partial excavation of the conduction channel, bases for blocks of anchorage of the penstock and ramp.

A.2 Description of the project activity (cont.):  The project was reactivated in 1999 and was linked to the 180 MW Ponte de Pedra hydropower plant.  The total height difference (head) between the headpond and the turbine/generator is approximately 60 meters. The dam takes advantage of the existing natural fall and the inlet water is at m above sea level.  The project will require 350 m conduction channel and a 160 m long penstock, and two turbines will be installed.

A.2 Description of the project activity (cont.): The project will deliver about 25,750 MWh/year to the Brazilian power system. Since the power plant is located at the end of the CEMAT (Centralis Eletricas Matogrossenses) distribution system, another important function of the Aquarius project is to improve the quality of power supply in the region.

B.1 Title and reference for the project category applicable to the project activity: Type 1 – Renewable Energy Projects Category 1.D – Renewable Electricity Generation for a Grid

B.2 Project category applicable to the project activity: The baseline is the kWh produced by the renewable generating unit multiplied by an emission coefficient (measured in kgCO 2 /kWh) calculated in a transparent and conservative manner as: The average of the “approximate operating margin” and the “build margin”, where: The “approximate operating margin” is the weighted average emissions (in kgCO2/kWh) of all generating sources serving the system, excluding hydro, geothermal, wind, low-cost biomass, nuclear and solar generation; (i) The “build margin” is the weighted average emissions (in kgCO2/kWh) of recent capacity additions to the system, defined as the lower of most recent 20% of plants built or the 5 most recent plants

B.3. Description of how the anthropogenic GHG emissions by sources are reduced below those that would have occurred in the absence of the registered CDM project activity Until mid 1990’s the electricity market was focused on large hydroelectric power plants operated by the state; 1990s consumption increased by 49% while installed capacity increased only by 35% requiring the use of stored energy in the form of water in the reservoirs. In 1995 onwards, international interest rate increased and investment capacity of the state decreased; The solution was privatization and liberalization of the market;

B.3. Description of how the anthropogenic… (cont.) In year 2000, the power demand was TWh with a generation capacity of 67.7 GW; with a gross generation of TWH; The only alternatives were improved energy efficiency or a more intensive use of existing plants; Improved energy efficiency generated limited result; Intensive use of existing plants was exploited; The reservoirs were not able to meet the demand resulting to power shortage in 2001; In 2001 onwards, rationing was imposed to reduce consumption by 20%

In 2000 the government launched the Thermal Electric Priority Plan (PPT) to increase the share of thermal electricity; The government promoted the building of thermal power plants based on imported natural gas; This was a significant shift from basically hydroelectric system to thermal power plants; The Wind Energy Incentive and Alternative Energy Sources Incentive Program foresee increase generation capacity by 3300 MW with other renewable energy other than hydro, offering long-term contracts with special conditions, lower transmission costs, lower interest rates from banks. There are still uncertainties on the benefits of these programs. B.3. Description of how the anthropogenic… (cont.)

F.1 If required by the host party, documentation on analysis of the environmental impacts of the project activity: The proposed project is a run-of-river hydropower plant, which involves no dam construction and no flooding, and thus no deforestation. Therefore, the environmental impact is very small compared to other types of power generation alternatives.
