It never rains...

8 July 2004

Several years of low rainfull in Brazil has severely reduced its hydroelectric production capacity. Since 2001, the government has carried out a two part programme that promotes energy conservation and constructs emergency generating plants on a large scale across the country, primarily at large population centres. Because of the costs involved and the short time available for getting the power plants online, the government has encouraged partnerships among energy companies, generator manufacturers and independent power producers.

Cummins has become a major supplier to this initiative, providing diesel and natural gas engine generator systems, as well as project management and financing. To date, Cummins has financed and commissioned three power systems totalling more than 113 MW.

The first emergency power plant brought online was a 64 MW project in the city of Sete Lagoas, state of Minas Gerais. It was commissioned in September of 2002 with a contract period running through to December 2004 and consists of 44 x 2000 DQKC PowerCommand diesel generator sets, each prime-rated at 1500 kW. The second emergency plant brought online, in December 2002, was a 44 MW diesel generating facility for the city of Anapolis that was financed and constructed by Cummins in partnership with Engebra, an independent power producer, and features 16 x 2000 DQKC PowerCommand generating sets, each providing 1600 kW of continuous power; and

17 x 1500 DFLE PowerCommand gensets, each supplying 1100 kW of continuous power, making a total of 44.3 MW. The energy generated during declared power emergencies will feed into the electrical grid of the Ceig Energy Utility Company in the state of Goijs in west-central Brazil.

The third project is located near the major city of Sao Paulo and consists of three 1750 GQNB PowerCommand lean-burn gas engine generators. These units deliver high fuel efficiency together with a very low exhaust emissions count. The installation was commissioned in September 2003 and will operate as a peaking facility during a contract period of 15 years. Partners in the project include Enatec, Benco and the local Cummins distributor, DCSP (Distribuidora Cummins Sao Paulo).
