No going back to fuel oil: ConEdison
Cheaper residual fuel oil prices will not lead to a resurgence in oil burn and US utilities plan to adhere to current emissions restrictions, senior planning analyst Peter Alexander at Consolidated Edison (ConEdison) told delegates at the Argus Fuel Oil & Feedstock conference in Miami.
Future implementation of new marine fuel market regulations has been expected to reduce demand for residual fuel oil for bunkering, placing downward pressure on fuel oil prices. But ConEdison, which provides gas, steam and electricity to customers in New York City and the surrounding areas, expected natural gas consumption as well as investments in renewable energy to meet future demand.
"Economics do not drive the show," said Alexander, who believed environmental regulations and auditors played a larger role in the company's decision-making process.
In addition to regulatory restrictions, utilities face technical challenges to burning fuel oil. Utilities' boilers require a load reduction to switch between fuels, raising the risk of a power trip. And an aging utility workforce has led to new hires with little experience in working with fuel oil.
The company's residual fuel oil consumption, in the form of 0.3pc sulphur high-pour fuel, has gradually declined from about 1mn bl in 2009 to a projected amount of less than 200,000 bl in 2016.
Until 2012, cheap natural gas prices drove ConEdison's demand. The utility also burns ultra-low sulphur kerosene in addition to fuel oil.
Market economics since 2013 "should [have increased] fuel oil demand, but fundamentals [were instead] impacted by environmental regulations," Alexander said.
In 2014, the company saw large spikes in natural gas prices, upwards of $120/mn Btu. And while oil prices have fallen closer to those of natural gas, environmental restrictions have impeded utilities from burning oil.
As a result of the increase in natural gas burn in lieu of fuel oil, the company's emissions have declined. Sulphur dioxide emissions declined from 6.0mn t in 2009 to 3.5mn t in 2014, nitrogen oxide release was down 2.4mn t to 2.2mn t over the same period, and carbon dioxide release was down from 2.3mn t to 2.2mn t.

Rio Grande do Sul remaneja fornecimento de gás
Sao Paulo, 17 May (Argus) — O fornecimento de gás natural no Rio Grande do Sul teve que ser redistribuído em razão das enchentes históricas no estado, com o diesel potencialmente voltando como combustível a usinas de energia para deixar mais gás disponível para a produção de GLP (gás de cozinha). O gasoduto Gasbol, que abastece o Sul do Brasil, não tem capacidade para atender à demanda da refinaria Alberto Pasqualini (Refap), da usina termelétrica de Canoas — controlada pela Petrobras — e das distribuidoras de gás natural da região, disse Jean Paul Prates, o então presidente-executivo da Petrobras, no início desta semana. A distribuidora de gás de Santa Catarina ajustou sua própria rede local para atender aos picos de demanda no Rio Grande do Sul por meio da malha de transporte de gás. A usina térmica de Canoas está operando com geração mínima de 150 GW, sendo 61pc provenientes de sua turbina a gás. A usina foi colocada em operação para restabelecer o fornecimento adequado de energia depois que as linhas de transmissão no Sul foram afetadas pelas enchentes. A Petrobras planeja usar um motor a diesel para aumentar a geração de energia. O atual custo variável unitário (CVU) para o diesel na usina de Canoas é de R1.115,29/MWh. A companhia petrolífera também está operando a Refap a 59pc de sua capacidade instalada máxima. Fortes chuvas no Rio Grande do Sul desde 29 de abril trouxeram inundações sem precedentes ao estado, causando uma crise humanitária e danos à infraestrutura. O clima extremo deixou 154 mortos, 98 desaparecidos e mais de 540 mil deslocados, segundo a defesa civil do estado.

Brazil's Rio Grande do Sul reallocates gas supply
Brazil's Rio Grande do Sul reallocates gas supply
Sao Paulo, 17 May (Argus) — Natural gas supply in Brazil's Rio Grande do Sul had to be redistributed because of the historic floods in the state, with diesel potentially making its way back as an power plant fuel to leave more gas available for LPG production. Gasbol, the natural gas transportation pipeline that supplies Brazil's south, does not have capacity to meet demand from the 201,000 b/d Alberto Pasqualini refinery (Refap), state-controlled Petrobras' Canoas thermal power plant and natural gas distributors in the region, according to Petrobras' then-chief executive Jean Paul Prates said earlier this week. The Santa Catarina state gas distributor has adjusted its own local network to meet peak demand in neighboring Rio Grande do Sul via the pipeline transportation network. The Canoas thermal plant is running at its minimum generation at 150GW, with 61pc coming from its gas turbine. The plant was brought on line to reinstate proper power supply after transmission lines in the south were affected by the floods. Petrobras plans to use a diesel engine to increase power generation. The current approved fuel cost (CVU) for diesel in the Canoas plant is of R1,115.29/MWh. Petrobras is also operating Refap at 59pc of its maximum installed capacity, at 119,506 b/d. Heavy showers in Rio Grande do Sul since 29 April brought unprecedented flooding to the state, causing a humanitarian crisis and infrastructure damage. The extreme weather has left 154 people dead, 98 missing and over 540,000 people displaced, according to the state's civil defense.

Houston area refiners weather hurricane-force winds
Houston area refiners weather hurricane-force winds
Houston, 17 May (Argus) — Over 2mn b/d of US refining capacity faced destructive winds Thursday evening as a major storm blew through Houston, Texas, but the damage reported so far has been minimal. Wind speeds of up to 78 Mph were recorded in northeast Houston and the Houston Ship Channel — home to five refineries with a combined 1.5mn b/d of capacity — faced winds up to 74 Mph, according to the National Weather Service . Further South in Galveston Bay, where Valero and Marathon Petroleum refineries total 818,000 b/d of capacity, max wind speeds of 51 Mph were recorded. Chevron's 112,000 b/d Pasadena refinery on the Ship Channel just east of downtown Houston sustained minor damage during the storm and continues to supply customers, the company said. ExxonMobil's 564,000 b/d Baytown refinery on the Ship Channel and 369,000 b/d Beaumont, Texas, refinery further east faced no significant impact from the storm and the company continues to supply customers, a spokesperson told Argus . Neither Phillips 66's 265,000 b/d Sweeny refinery southwest of Houston nor its 264,000 b/d Lake Charles refinery 140 miles east in Louisiana were affected by the storm, a spokesperson said. There was no damage at Motiva's 626,000 b/d Port Arthur, Texas, refinery according to the company. Marathon Petroleum declined to comment on operations at its 593,000 b/d Galveston Bay refinery. Valero, LyondellBasell, Pemex, Total, Calcasieu and Citgo did not immediately respond to requests for comment on operations at their refineries in the Houston area, Port Arthur and Lake Charles. A roughly eight-mile portion of the Houston Ship Channel from the Sidney Sherman Bridge to Greens Bayou closed from 9pm ET 16 May to 1am ET today when two ships brokeaway from their moorings, and officials looked in a potential fuel oil spill, according to the US Coast Guard. The portion that closed provides access to Valero's 215,000 b/d Houston refinery, LyondellBasell's 264,000 b/d Houston refinery and Chevron's Pasadena refinery.

Japan’s Jera to handle 35mn t/yr LNG until FY2035-36
Japan’s Jera to handle 35mn t/yr LNG until FY2035-36
Osaka, 17 May (Argus) — Japan's largest LNG importer Jera plans to maintain its LNG handling volumes at no less than 35mn t/yr until the April 2035-March 2036 fiscal year. Rising renewable power supplies and the possible return of more nuclear reactors are likely to pressure LNG demand from Japan's power sector. Jera consumed 23mn t of LNG in 2023-24, down by 3pc on the year, although it handled 35mn t through its global operations during the same year. But Jera needs to secure sufficient LNG supplies to adjust for imbalances in electricity supplies and ensure power security, through more flexible operations. It is also looking to further promote LNG along with renewable electricity in Asian countries, while helping to reduce their dependence on coal- and oil-fired power generators. The 2035 target for LNG is part of Jera's three pillars of strategic focus, along with renewables as well as hydrogen and ammonia , which was announced on 16 May to spur decarbonisation towards its 2050 net zero emissions goal. The company plans to invest ¥5 trillion ($32bn) for these three areas over 2024-36. Jera also aims to retire all supercritical or less efficient coal-fired units by 2030-31 . This would help achieve the company's target of cutting CO2 emissions from its domestic business by at least 60pc against 2013-14 levels by 2035-36.
