ISA CTEEP is part of the National Interconnected System (“SIN”) which incorporates the Brazilian electricity grid as a whole (with the exception of some isolated systems) and serves approximately 99% of the system’s total load. Through its activities and its wholly and jointly-owned subsidiaries, ISA CTEEP is present in 17 states in the country, transmitting approximately 33% of all electricity produced in Brazil and 94% of the energy in the State of São Paulo.
The coordination and control of the Company’s installations’ operations and all of SIN’s electric generation and transmission installations is the responsibility of the National Electric Energy System Operator (“ONS”), subject to the inspection and regulation of the National Electric Energy Agency (“ANEEL”).
The concessions that compose the transmission market in Brazil may be divided in 3 main categories:
|Concessions prior to 1998|
RAP in operation: 70%
|Concessions between 1999 and 2006|
RAP in operation: 1%
|Concessions after 2008|
RAP in operation: 14%
RAP under construction: 15%
The transmission companies’ revenue, also known as RAP (Allowed Annual Revenue) is approved by ANEEL and disclosed annually (normally in the month of June) in the Periodic Tariff Review, which establishes the RAP for the next 12 months, adjusted by inflation.
Please find below the composition of the RAP:
RBSE: Receivables related to the non-depreciated assets in operation in May/2000
O&M: Revenues related to the operation and maintenance services
New Investments (NI): Organic growth (new investments)
Variable Parcel (PV): Revenue reduction due to unavailability
Adjustment Parcel (PA): Compensates excess or deficit of revenues in the previews tariff cycle
