Petrobras expanded the supply of fuels for thermal plants, which allowed it to increase, in nine months (from September 2020 to June 2021), the thermoelectric generation of its plants and customers from around 2,000 MW to almost 8,000 MW.
In the same period, the volume of gas made available by Petrobras for thermoelectric plants ranged from 12 million to 35 million cubic meters per day.
The increase took place through a series of anticipatory measures to maximize the supply of natural gas to the market, including:
- expansion of the capacity of the Guanabara Bay Regasification Terminal, from 20 million to 30 million m³/ day;
- positioning of the two regasifier ships in the Terminals of Bahia (TR-BA) and Rio de Janeiro;
- import of LNG (liquefied natural gas), reaching more than 14 ships per month;
- ANP's flexibility in the specification of the gas processed at the Caraguatatuba treatment unit and
- the interconnection of Routes 1 and 2 for the flow of pre-salt gas.
In addition, the company continues to negotiate a new interruptible contract with Bolivia and provide alternatives for the availability of a third regasification vessel.
Regarding the supply of fuel oil for use by thermoelectric customers, the supply increased from zero in September 2020 to 183 thousand tons in June 2021 and the volume of diesel for this purpose varied from zero to 44 thousand m3 per month in the same period . The increase in supply was possible due to operational optimizations in refineries and imports.
Gas supply is reinforced during scheduled shutdown
The postponement of the scheduled shutdown of the Mexilhao platform and the Rota 1 gas pipeline to August 29 will bring benefits to the country's electricity sector, compared to the previous schedule, as it reduces the impact period of the stoppage in sales contracts, allowing an increase in electricity generation using natural gas, due to the availability of gas for another 14 days for the Cubatão, Araucária, Linhares, Santa Cruz, William Arjona and Norte Fluminense plants, in addition to Termopernambuco, that will no longer stop during this period.
The transfer of the ship from Pecém to Bahia allows the service of UTEs in the Southeast and South (UTEs Arjona and Araucária, total of 650 MW), which, together with the diesel generation at UTE Termoceará (200 MW), more than compensates for the temporary outages in the Northeast (about 750 MW), providing capacity of about 100 MW more during the repositioning period.
Petrobras, once again, reinforces that stops such as those at Mexilhao and Rota 1, given their complexities and scope, are necessarily planned well in advance - therefore, scheduled - considering the mandatory regulatory deadlines, the need to contract goods and services and coordination with other agents in the sector to ensure compliance with contractual commitments with the market.
Intervention is necessary to ensure safety and prevent accidents, reinforcing the integrity of highly complex equipment and installations, whose inspection and maintenance must be carried out in accordance with technical norms and standards. Petrobras reaffirms safety as a fundamental value.
The company continues to comply with all contracts, in accordance with the established terms and deadlines, and makes every effort to maximize the gas supply and guarantee the reliability of supply to its customers.
Petrobras actively contributes as part of the solution to the challenges caused by the low water inflow that affects the country. The company remains available to provide additional data that contribute to the proper understanding of all issues related to the topic, adequately informing society as a whole.
