40MW Power Plant Belo Jardim, Rio Branco, Acre, Brazil

The challenge

Rio Branco is located on the Peruvian-Brazilian border. Due to its remote location, it is connected to the electricity grid through non-reliable long-distance transmission lines. The local government opted to obtain electricity reliability, restore local population's trust and resume the city's intense economic development – all within less than two months, before the 2011 Carnival. 

Unique site challenges included long non-paved roads and other faulty mobilization conditions, heavy and continuous tropical rain, mud, thick plants and bushes and wild animals.

Our Rapid, Cost-Effective Solution

GenRent planned, constructed and commissioned a 40 MW stand-by diesel power plant, including equipment transportation and a construction of 69KV Substation, all within a record-breaking period of less than 2 months. GenRent is also responsible for the operation and maintenance of the power plant since it was first connected to the electricity grid.

Civil

• earthwork and ground compression
• casting of concrete floors and creating paved areas
• assembly of the water, fuel and sewage system (including a system for drinking water, sewage, rain and oily water drainage, separation boxes for water and oil)
• assembly of fire-fighting system (including pressurized hydrants, fire extinguishers, fire-fighting foam system, fire alarm system)
• construction of the brick control and administration center

Mechanical

• assembly of 300m³ and 10m³ fuel tanks
• assembly of carbon steel pipe line for interconnection and supply of fuel oil, lubrication oil and water and oil separation systems
• assembly of Fuel pumps, exhaustion pipe line, fuel and lubricant filters, flow meters, purifiers and many more

Electrical

• assembly of Equipment: 440VA-13.8KVA and 69KVA Step-Up Transformers, MV Protection Breakers, protection and power distribution boards
• assembly of outdoors 69KV Substation, including the construction and assembly of ground infrastructure and civil equipment, protection system, control system, bare copper cables, switches, insulators, lightning protection
• assembly of the electrical protection comprehensive system
• assembly of electrical command and supervision system: including the interconnection with the transmission grid, all through optical fibers and top of the line interfaces
• assembly of comprehensive communication system: for the purposes of communication between the power plant and the transmission grid's operational center, via satellite and via conventional system
• Advanced Control and Monitoring System: the power plant had to attend flexible demand and change of load, be remotely monitored and controlled, operate in conjunction with the power authority and interface with the specific client's protocol. The GenRent's SCADA base control system allows us as operators to monitor and control each generator in the power plant, including engine parameters, fuel system and all main circuit breakers in the substation

Environment Monitoring

• all our generation units as well as all the industrial residue process are monitored according to ABNT and CONAMA standards
• the gas emissions originating from the power stations fuel burning are monitored periodically and are in accordance with applicable law and standards
• the oily or non-oily residue emission is monitored periodically at the power plant exit point. The water and oil separation box is cleaned and monitored periodically as well
• in addition, noise levels are monitored to meet applicable regulation, with operational interventions whenever required
