Balticconnector gas pipe off line for suspected leak
The Balticconnector gas pipeline linking Estonia and Finland was taken off line on Sunday morning following a sudden drop in pressure because of a suspected leak, Finnish transmission system operator (TSO) Gasgrid Finland said.
Around 02:00 local time on the morning of 8 October an "unusual pressure drop" was noticed by the Finnish and Estonian TSOs on the Balticconnector, leading them to suspect a leak in the offshore pipe. The valves were subsequently shut and the pipeline taken off line. The cause of the potential leak is unknown at present, but strong storms buffeted the Baltic region and Finland over the weekend, with Estonia's rescue board asking the public to stay home. The two TSOs are planning a joint inspection of the line to locate the leak site, but Gasgrid expects that accessing the pipeline for investigation work "is likely to take at least a few days". If a leak is confirmed, then repair work "could take at least several months, depending on the damage", Gasgrid said.
The Finnish market is currently stably supplied by the Inkoo LNG terminal, with sendout dropping to just under 49GWh on 8 October from 72 GWh/d on 1-7 October as a result of downward adjustments to sendout now that transmission capacity towards Estonia is unavailable. The closure of the Balticconnector will have "no impact on the gas supply to Estonian consumers" as gas will be supplied from Latvia, Estonian TSO Elering said.
An extended outage on the Balticconnector could bring significantly more challenges when the weather turns colder later in the year and gas demand increases. No cargo slots have been booked at Inkoo between late November and early March, according to Gasgrid's latest schedule. But market participants have been "instructed to ensure the gas supply they need by ordering it to Inkoo or the Hamina LNG terminal, so that the continuity of gas supply is secured in the coming winter season", Gasgrid said on 9 October. Market participants said that they have shied away from booking winter slots at Inkoo because of ice concerns.
The Finnish government is not planning any additional support measures, such as discounts on slot bookings or government-backed insurance, and remains "convinced that the new situation will increase the willingness to import LNG to Inkoo", Finland's director general for energy, Riku Huttunen, told Argus. "We have best-in-class ice breaking capacity in Finland — this helps regarding ice conditions," he added.
The Inkoo terminal operator will "restrain further reservation requests for available spot slots for the winter period" until more information is received from the TSOs regarding the length of interruption, as the interruption on the Balticconnector may effect the terminal's commercial and technical usability, it said in an urgent market message on Monday. "Best efforts" will be made to publish the availability and schedule on 17 October, it said.
The smaller-scale Hamina terminal also supplies gas to the Finnish grid, from which Estonian supplier Alexela is supplying its customers, the firm told Argus. Alexela has enough gas from Hamina "so our clients are safe", energy portfolio manager Kalvi Nou said, adding that it is "too early to speculate at this point what may happen over the course of winter". But "the longer the outage, the more difficult it will be [to predict]. It depends on whether we are talking about a month or several months", Nou said.
The Finnish market's largest supplier, state-owned utility Gasum, told Argus that the market remains stable. "We are able to deliver gas to Gasum's customers" as there is gas at Inkoo and the upcoming slots at the terminal have been booked. In the case of a prolonged outage, market participants can supply their customers from Inkoo and Hamina. Gasum "follows the situation closely together with relevant authorities and other stakeholders". The firm has five slots booked at Inkoo for this gas year, with one in October and the rest in the second and third quarters of next year, Gasum told Argus.
The sole user of Inkoo in the 2022-23 gas year, Eesti Gaas, did not immediately respond to a request for comment from Argus. The firm's chief executive, Margus Kaasik, told Estonian state news agency ERR that Eesti Gaas' Baltic customers would be supplied with gas stored in Latvia and from a cargo scheduled to arrive at Lithuania's Klaipeda terminal on 10 October. Eesti Gaas "does not foresee any shortage of supplies in the foreseeable future", he said.
Finnish gas, power prices rise
Finnish gas and power prices jumped on 9 October following news of the closure.
The Finnish day-ahead gas price on the GetBaltic exchange jumped from €38.17/MWh on 7 October to €43.19/MWh on 8 October and €46.03/MWh on 9 October.
Similarly, Finnish day-ahead power prices on the Nord Pool exchange rose to €87.07/MWh on 9 October from just €2.22/MWh the previous day (see graph).
The Finnish power generation mix is not particularly reliant on gas, with gas making up just 1.9pc of the overall stack so far this month, according to data from Fraunhofer ISE. But gas is important for meeting dispatchable demand when renewable generation declines. Most Finnish households are not heated directly by gas, with more than 1.4mn heat pumps deployed in Finland out of a population of just 5.5mn. But gas is used indirectly for heating homes, as it is often used in combined heat and power plants and district heating.

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.

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.

Biomass start-ups lift Japan's Renova April power sales
Biomass start-ups lift Japan's Renova April power sales
Tokyo, 17 May (Argus) — Japanese renewable power developer Renova's electricity sales doubled on the year in April, following the start-up of three biomass power plants in the past six months. Renova sold 199,601MWh of electricity — including solar, biomass and geothermal — in April, double the 99,857MWh a year earlier, the company announced on 13 May. The 75MW Sendai Gamo plant in northeastern Miyagi prefecture started operations in November 2023 and produced 40,753MWh in April. The 74.8MW Tokushima Tsuda plant in western Tokushima prefecture, which was commissioned in December 2023, generated 10,870MWh in April. The 75MW Ishinomaki Hibarino plant in Miyagi began normal runs in March and supplied 49,495MWh in April. Renova plans to add 124.9MW biomass-fired capacity in the April 2024-March 2025 fiscal year, with the 75MW Omaezaki plant in central Shizuoka city scheduled to begin commercial operations in July, followed by the 49.9MW Karatsu plant in southern Saga city in December. Omaezaki is currently conducting trial runs and Karatsu is under construction. The additions will increase Renova's biomass-fired capacity to 445MW.

Chinese importers seek five LNG cargoes for Jun-Sep
Chinese importers seek five LNG cargoes for Jun-Sep
Shanghai, 15 May (Argus) — Five Chinese importers, mostly second-tier buyers, are each seeking one LNG cargo for June-September delivery, according to an official notice published by China's national pipeline operator PipeChina on 15 May. The five importers are PipeChina, Chinese independent ENN, Hong Kong-listed city gas firm China Resources Gas, Hong Kong-based Towngas and state-owned China Gas. PipeChina and ENN have indicated a target price of at most $9.50/mn Btu for their intended cargoes, both for delivery to PipeChina's 6mn t/yr Tianjin terminal. China Gas has indicated a target price of at most $9.30/mn Btu for delivery to PipeChina's 6mn t/yr Beihai termial. China Resources Gas and Towngas have both indicated a target price of at most $9/mn Btu for delivery to PipeChina's 2mn t/yr Yuedong and Tianjin terminals, respectively. This consolidated requirement came about because of a need for PipeChina to better leverage on its infrastructure advantages and, at the same time, meet the varying needs of gas importers and consumers in the country. But this requirement comes at a time when spot LNG prices are still somewhat higher than the importers' targeted prices. But the importers can choose not to buy if offers are not within their expectations. The front-half month of the ANEA, the Argus assessment for spot LNG deliveries to northeast Asia, was last assessed at $10.485/mn Btu on 15 May. Chinese importers mostly perceive spot prices below $9-9.50/mn Btu for June-September deliveries to be unattainable for now because there is strong buying interest from south and southeast Asia in particular. Indian state-controlled refiner IOC most recently bought LNG for delivery between 22 May and 15 June at around $10.60/mn Btu, through a tender that closed on 14 May. Thailand's state-controlled PTT most recently bought three deliveries for 9-10 July, 16-17 July and 22-23 July through a tender that closed on 13 May , at just slightly above $10.50/mn Btu. The most recent spot transaction was Japanese utility Tohoku Electric's purchase of a 10-30 June delivery at around $10.55/mn Btu through a tender that closed on 14 May . This is at least $1/mn Btu higher than Chinese importers' indications. Summer requirements have so far been muted but concerns among buyers about potential supply disruptions remain. Malaysia's 30mn t/yr Bintulu LNG export terminal suffered a power loss on 10 May, but this issue may have been resolved as of early on 15 May, according to offtakers. Some unspecified upstream issues may still be affecting production at the Bintulu facility, resulting in Malaysia's state-owned Petronas having to ask some of its buyers for cargo deferments, according to offtakers.
