Brazil returned on Friday, 14, the exchange of energy with Venezuela, according to information provided by the National Electric System Operator (ONS), in its Preliminary Daily Operation (IPDO) informative.
That day, the transmission line was linked in 230 kV Boa Vista/Santa Elena, which complements the interconnection of the “Roraima system” with the Venezuelan system, allowing the 15 megawatts commercial importation to begin, wrote the report.
In January, the Electric Sector Monitoring Committee (CMSE) deliberated by Bolt Energy from Venezuela to serve the Roraima system. The studies, however, extended beyond the initially planned.
On Friday, 14, without fanfare, I import 10 megawatts (MW). IPDO shows that only 6 MW were actually imported.
On Saturday, 15, the exchange of 15 MW of energy was scheduled, but only 7 MW was verified. The lower than expected volume may be related to a problem faced by the Boa Vista/Santa Elisa transmission line. According to the ONS, the line shutdown was recorded at 4:16 pm. At that moment there was also the dismissal of the Jaguatirica II thermoelectric plant, which was generating 67 MW at the moment. As a result, 103 MW was interrupted in the Roraima system, which corresponds to 65% of the state’s load. Minutes later, at 4:31 pm, the rest of the load of this system, corresponding to the 60 MW that still remained on, also fell. The recomposition of the cargo started at 4:52 pm, being completed at 17:50.
On Sunday, 16, there was a 9 MW exchange, although 15 MW were scheduled. There were no occurrences, according to the IPDO.

Sought to comment on these operations, the ONS declined to comment.
Previously, ONS had informed that energy imports aimed to “reduce operating costs and raise safety and reliability of consumer service”. According to the operator, depending on the load of the state of Roraima, the expectation was an economic benefit of up to R $ 500 thousand per day with the importation of up to 15 megawatts (MW) of the Venezuelan system, worth R $ 1,096.11 by megawatt-hour (MWh).
Aneel approves use of R $ 41 million of fuel bill for import from Venezuela by Bolt

The board of the National Electric Energy Agency (Aneel) approved last Tuesday, 18, that R $ 41.24 million of the fuel consumption account (CCC) are used to fund the importation of electricity from Venezuela from January to April this year.
CCC is the subsidy used to fund the production of thermoelectric energy in isolated systems, those not connected to the National Interconnected System (SIN), as is the case of Roraima, a state that receives the energy sent by Venezuelans. This year, the CCC budget is estimated at R $ 10.3 billion.
Import will be done by Bolt Energy Energy Trading at R $ 1,096.11 per Megawatt-Hora (MWh). The operation began last week, even after the National Electric System Operator (ONS) stated the need for complementary information from the Venezuela authorities to reach a conclusion about the resumption of the operation.

Last year, Aneel approved the allocation of R $ 17 08 million of the same account to perform the operation by Ambar Energia, from the J&F group, but the business did not materialize in the face of non -testing by ONS in the year past.
