Operating Performance
According to Energy Research Company (EPE) data, in 2010 the national consumption of electric energy in Brazil increased by 7,8% compared with 2009, amounting to 419,016 GWh (gigawatts-hour).
Such performance was favored by the positive economic scenario recorded then; the residence and business classes maintained a high level of increase, and the industrial consumption consolidated the recovery started in the second half of 2009 after the 2008 crisis. At the same time, the electricity load of the National Interconnected System (SIN) presented an annual increase of 8.3% in relation to the load verified in 2009.
Accordingly, the total amount of energy transported by CTEEP, accounting for nearly the total electricity supply in the state of São Paulo, was 141,127 GWh in 2010 – which accounts for 33.7% of all the electricity consumed in the country and an increase of 5.9% over the preceding year.
2010 was also marked by great events – such as the Summer Plan, World Cup, elections and the GP of Formula 1 – which have a direct impact on the consumption of electricity. To guarantee the system reliability in such periods, CTEEP set up special servicing plans with a number of professionals mobilized to promptly take actions in case of an incident.
In view of the successive increases in the demand, the challenge in 2010 was to assure reliable electricity transmission, since the revenue of the Company is directly associated with the availability of its main assets, transmission lines and transformers. Any unavailability of such assets will generate reduction to the revenue, by virtue of the variable portion. (PV).
CTEEP accomplished significant results due to the ongoing advances made in modernization of the facilities and installations, training, employees’ professional skills training and purchase of innovative technologies to operate the system.
In July 2010, for the second year in a row, ANEEL granted a bonus to the Company, as a result of the high availability of its assets. In 2010 the bonus represented R$4.9 million to CTEEP, an amount equal to 34% of the total distributed, by this same mechanism, to the transmission agents. Moreover, the Company improved its assets availability indexes, which were above the targets set for the year: 99.97% in transmission lines; 99.98% in reactors; and 99.95% in transformers, in addition to having recorded its best level in the non-supplied energy index (ENS).
Availability of Assets
CTEEP continued the activities of professional skills training to its team, with prominence to the real-time operation training, performed with the participation of generation and distribution companies and follow-up by ONS (National Electric System Operator) over the year. Such initiative, carried out in the Training Simulator of System Operators, proved to be an important resource to enable our professionals to cope with real situations in the system, improving the level of response, particularly recoveries regarding several types of disorders.
With the same purpose of maintaining its team prepared, CTEEP is conducting the recertification of the Control Center operators, in line with the standards set out by ONS. During the process, the professionals´ technical, physical and psychological aspects are reassessed, as well as their responses when facing significant disorders in the system. Despite not being mandatory, the recertifications are audited by an external consulting company, assuring effectiveness of the process. Likewise, certifications and recertifications of technician as well as technical assistants working in the substations of the Company are also being conducted.
Another fundamental aspect of the operational performance is maintenance, essential to assure system operation efficiency and quality. CTEEP has adopted the concept of reliability centered maintenance. (MCC) since 2008, which allows for periodical detailed analysis and check. In 2010, 1,680 maintenance procedures were performed on the Company's main equipment (circuit breakers, reactors, disconnect switches and transformers) and further recorded.
CTEEP´s operating performance in 2010 was also marked by modernization of the assets and by the adoption of Technologies and controls of the electric system, with prominence to:
- Extension of the digitalization Project to the Mairiporã, Porto Ferreira and Jaguari substations which received new protection, measurement, control and supervision systems that provide a more reliable and safe operation.
- Implantation of the RTDS (Real Time Digital Simulator) that will allow CTEEP to integrate a selected group of companies capable of performing simulations in the electrical network with milliseconds details and will allow a deeper analysis of the electrical network as well as more accurate and quicker adjustments to the control and protection systems.
- modernization of protections, inclusion of digital protections and installation of new circuit breakers, with better performance and advanced technology that will provide more reliability to the system as well as quick analysis of the incidents.
