South Korean nuclear restarts to help meet peak demand
Returning nuclear capacity in South Korea is expected to help the country cope with a spike in seasonal temperatures and peak power demand.
Three nuclear units are expected to resume operations in the near term, according to a notice published by energy and trade ministry Motie today.
These are the 1.4GW Shin Kori 4 reactor, which has been off line because of an unplanned outage since 29 May, and the 700MW Wolsong 3 and 1GW Shin Wolsong 1 units.
Shin Wolsong 1 was expected to return from maintenance on 27 July, but instead started up yesterday and will reach full capacity by 21 July, the government said. Wolsong 3 is due to return on 23 July, as scheduled.
The Shin Kori 4 reactor is awaiting approval to restart following its outage and the completion of an inspection on 15 July and could resume operations on 21 July, the ministry said.
If these units return as planned, nuclear availability would average 16.6GW this week, from 15.5GW last week. Average July availability would be 16.2GW, down from actual generation of 18.4GW in July 2020.
The boost to nuclear availability should help to balance peak demand, but is unlikely to drastically slow the expected rise in generation from fossil fuel compared with a year earlier as power demand surges.
Daily peak power demand has averaged 77.9GW so far this month, up from 67.6GW a year earlier. Daily mean Seoul temperatures are forecast to average 28.2°C this month, which would be only the second time in 10 years that July temperatures have surpassed 28°C and higher than the 26.3°C 10-year average for the month.
Argus analysis shows that combined coal and gas-fired generation may need to rise by 6.4GW on the year to 45.6GW this month.

Western Australia to allow some onshore gas exports
Western Australia to allow some onshore gas exports
Darwin, 19 September (Argus) — Western Australia's (WA) state government will allow onshore developers of gas fields to export about 20pc of their output as LNG during a five-year window, in response to a growing failure to bring on new supplies for the domestic market. WA previously banned onshore gas exports, except in the case of Australian independent Beach Energy's 250 TJ/d (6.7mn m³/d) Waitsia stage 2 project . Beach may be required to share its infrastructure with fellow Perth basin firms, the WA government said, to expedite market access for new projects. Australian mining firm Mineral Resources, which has argued for permission to export 85pc of the gas from its Lockyer project as LNG and fellow WA-based firm Strike Energy may benefit from the changes, as both hold significant reserves in the Perth basin. The changes apply to new onshore developments or existing projects seeking to expand production. Developers are required to reserve 80pc of gas produced for WA, with this rising to 100pc from 2031 onwards. The policy shift follows dire outlooks for WA's gas supplies as the state attempts to wean itself off coal-fired power generation. It currently contributes about a third of the electricity into the state's largest power grid. A parliamentary report last month warned WA cannot rely on sporadic appeals for more gas to meet demand. "These policy changes are sensible responses that balance the need for Western Australia to secure its energy future while encouraging onshore producers to bring on more gas supply as and when it is needed," mines and petroleum Minister David Michael said on 19 September. The 15pc reservation for offshore LNG projects will continue, while WA has promised more transparency on the policy with the publication of a yearly WA Domestic Gas Statement to reveal how producers are meeting obligations, with a review to take place after two years. An interim parliamentary report tabled earlier this year showed about 8pc of the state's offshore gas output has reached WA consumers since 2006, representing just over half the required volumes. Following public criticism of LNG producers' contributions, Australian independent Woodside Energy has since pledged an extra 32PJ (854mn m³) of domestic supplies by the end of 2025 . WA will also seek to strengthen laws designed to prevent companies banking prospective onshore oil and gas tenements, with a review into the "use it or lose it" policy to be led by the state's energy department.

EU needs future power grids task force: Ember
EU needs future power grids task force: Ember
London, 18 September (Argus) — The EU must put in place a future grid task force to bring together scattered legislation and directives, so the bloc can better implement its power grid roadmap and integrate renewable capacity, according to UK-based think-tank Ember. Integrating intermittent renewables into the power grid adequately will require substantial upgrades to the power network across the continent. This is a political priority for the EU but responsibility is shared across a number of European governmental bodies, Ember said. Most of the 80 action points laid out in EU policy and legislation are the European Commission's responsibility, but some objectives are overseen by EU distribution system body DSO Entity, European grid operators association Entso-E, energy regulators' agency Acer, the EU's High-Level Forum on European Standardisation, and individual member states. The policy framework is a "positive step", Ember said. But significant grid work and modernisation are needed, which would be best met through a single body that can ensure "timely and effective" delivery, according to Ember. A dedicated task force would centralise policy support and monitoring through a single channel, provide access to financing from the European Investment Bank and European Bank for Reconstruction and Development, and develop a clear roadmap for all actions that are currently in the commission's remit. The need for a roadmap is significant as several of the commission's targets do not have scheduled completion dates, Ember said. The EU must centralise funding access for member states and grid operators to ensure stakeholders can use as much of the funding available to them as possible, according to Ember. Funding is currently underutilised and spread across several financial instruments. In addition to uniting these instruments, the access mechanisms should be streamlined and administrative burdens reduced so that stakeholders of varying sizes can utilise these funds. The EU should provide targeted funding for pilot projects on grid digitalisation, and then create a "technical toolbox" to support the digitalisation of distribution grids. The toolbox would detail best practice approaches, standardisation guidelines and interoperability technologies to ease digitalising the power network. These innovative grid technologies (IGTs) or grid-enhancing technologies (GETs) use existing infrastructure to improve renewable integration while reducing overall investment needs. IGT and GET technologies could improve renewable integration with costly network upgrades by as much as 40pc, according to a study by Latvian grid operator AST.

Indonesian Sumsel 1 coal-fired unit eyes December start
Indonesian Sumsel 1 coal-fired unit eyes December start
Manila, 18 September (Argus) — The first 300MW unit of the 600MW Sumsel 1 mine-mouth coal-fired power plant in Indonesia's south Sumatra province is scheduled to begin commercial operations in December following several years of delays. The plant, which is located in Muara Enim regency, is being developed by China Shenhua Energy and Lion Power Energy, which have 75pc and 25pc respective stakes in the project. Once fully operational it is expected to consume around 2-3mn t/yr of coal. Lion will be responsible for sourcing the coal. The $750mn plant is part of Indonesia's 35GW power generation roadmap developed by the Indonesian government in 2015. The project was contracted to China Shenhua Energy in 2016. The first unit at the plant was originally scheduled for completion by 2020. But land acquisition delays and the Covid-19 pandemic and resulting restrictions on the movement of people and travel bans delayed construction, Lion said. Construction work on the plant structure is now in the final stages and operational testing is expected to begin soon. But hitting the operational target date also depends on the completion of a 275kV high-voltage line that will connect the plant to the grid, state-owned utility PLN said. The 80km transmission line will pass through four districts in south Sumatra. The local government is pushing for the acceleration of the voltage line construction and has instructed the sub-district head and local government offices to provide support for the power line construction, PLN said. Sumsel 1, once fully operational, will operate on a build-own-operate basis with a 25-year power supply contract with PLN, the utility said.

USCG updates ongoing lower Mississippi restrictions
USCG updates ongoing lower Mississippi restrictions
Houston, 17 September (Argus) — The US Coast Guard (USCG) will further limit northbound movement for barges transiting the lower Mississippi River despite slightly higher water levels following Hurricane Francine's landfall late last week. The USCG announced on 16 September that all northbound traffic traveling from Tunica, Mississippi, to Tiptonville, Tennessee, can only have five barges wide and only four of those can be loaded. Barges also cannot be loaded deeper than 9.5ft. Any southbound traffic from Vicksburg, Mississippi, to Tunica cannot move more than seven barges wide or be drafted deeper than 10.5ft. Southbound traffic from Tiptonville to Tunica can only be six barges wide or less and cannot have a draft greater than 10ft. The USCG has updated lower Mississippi river draft restrictions about four times since the end of August, but this is the third year in a row of notable low water for the fall on the lower Mississippi river which has triggered draft restrictions to arrive more quickly than previous years. Hurricane Francine brought significant rainfall to the lower Mississippi at the end of last week . But this has not eased the minds of mariners, who anticipate the water may leave as quickly as it arrived.
