renewable energy resources to AIPSAA to develop the electricity generation
activity in the facilities of the thermal power station “Paramonga I”. Such
concession was granted through the Definite Concession Contract of Generation
with Renewable Energy Resources Nº 344 2009.
2.4.5 Technological Aspects
Technical and Interconnection Features
“Agro Industrial Paramonga” generates electric and thermal power with a
sugarcane byproduct: The bagasse. These wastes have a high calorific value, so
when they are burned-out, they cause energy with smaller impact to the
environment.
The watertube boiler that runs on bagasse of sugar cane, produces 115 Ton/h of
with a temperature of 400º C and 42,5 bar of pressure. This steam circulates for a
pipe of Ø12” sch. 80, and is connected to a SIEMENS’s turbine which is located
in the housepower (MEM, 2011b).
The turbine delivers extraction steams in a temperature of 126º C and 2,39 bar of
pressure, collected in a pipe of Ø36” sch.10, that is conducted to the ship of mills.
The steam flow that was no extracted for the process of elaboration of sugar will
continue expanding in the turbine until a maximum vacuum pressure of 0,16 bar
generating the additional electric power.
Also count on a steam reducing station that works when in a determined moment
the turbine stops delivering steam. In this station it is reduced the entrance
pressure of 42,24 bar to 1,38 bar, and at the same time the steam is saturated to be
able to deliver it to the system.
The electric substation has 2 transformers. The first one is a three-phase
transformer of 1 250 kVA of power and 13.8/0.480 kV and the second one is a
three-phase transformer for lighting of 35 kVA 480/230 V.
The interconnection with the SEIN is executed in the bars of 13,8 kV of the
“Paramonga” Substation of 138/13.8 kV property of the concessionary company
“SN POWER” (CAHUA).
Availability of the Resource
The supply of energy and power is related to the stock of fuel for the
Cogeneration Station, it means bagasse. Before the project’s execution, the plant
of “AIPSAA” had a surplus of bagasse that justified its implementation.
By 2009, the bagasse production amounted to 29 thousand Ton/month, with an
average consumption in the boiler of 26 thousand Ton/month, generating a
bagasse surplus of 3 thousand Ton/month (MEM, 2011b).
