Where the Equivalent Electrical Efficiency is calculated through the following
formula:
E :
V :
Q :
Electric power measured in generator terminals and expressed
in MWh.
Is the amount of useful heat from the cogeneration station
exclusively, expressed in MWh.
Power given by the fuel used, calculated in MWh based on its
lower calorific value
Even when the cogeneration station “Paramonga I” was qualified to take that
mechanism, the senior management though it was more convenient to choose
taking part in the first RER Auction and being awarded with a portion of the
energy offered. This action guaranteed in a large extent the economical
sustainability of the project.
On the other hand, in order to insure the profitability of the project, the
cogeneration station “Paramonga I” has qualified to apply to the CDM. This and
the benefits granted by the awarding of the RER auction, made the project
sustainable in time.
Tariffs
The cogeneration station “Paramonga I” was one of the two projects with biomass
which were awarded in the First Auction of Renewable Energies (February,
2010). The offered price for this energy was of 52, 00 US$/MWh and this is the
same tariff that is awarded by the OSINERGMIN (OSINERGMIN, 2011).
Like all cases of RER stations, net injections of energy up to the limit of the
Awarded Energy are remunerated at the Awarded Tariff., while net injections of
