UK vote to leave EU increases market uncertainty
Investors seeking to develop new power infrastructure in the UK face increasing uncertainty after the country voted to leave the EU in a referendum held yesterday. The prospect of an uncertain investment environment comes at a time when the government is trying to replace the country's ageing nuclear and coal-fired power plants.
The heightened uncertainty and risk for developers over the coming years as the UK negotiates its exit from the EU is likely to mean that investors will seek higher returns for their projects before committing investment, a report commissioned by transmission system operator National Grid in the lead-up to the vote said.
The UK government has pledged to close all of its remaining unabated coal-fired plants by 2025 and replace them with new gas-fired and nuclear plants.
The pound had dropped to its lowest level in more than 30 years this morning, with a weaker pound not only effectively lifting the relative cost of importing power, gas and coal, but also lifting the cost of imports for the materials and equipment required to build new energy infrastructure. Planned new plant projects may now face final investment decision delays, which could mean that remaining coal-fired plants are required to remain on line to ensure security of supply.
The owners of the country's coal-fired plants had been required to make a decision by 2020 as to whether they wish to invest in the required emissions-reduction technology for compliance with the EU's industrial emissions directive (IED) or face closure. The UK's vote to leave the EU may allow such facilities to evade this deadline and continue operating into the mid-2020s, but the country would have to remove the legislation from its national law for this to happen.
The UK is also likely to have to re-negotiate its membership of the European internal energy market (IEM) during the planned two-year negotiating period for securing its exit if it wishes to remain a part of it, and retain the associated benefits of power market coupling initiatives and cross-border market balancing.
EU membership is not mandatory for involvement in the IEM, with Norway having joined despite not being a member of the EU. But even if the UK did re-join the IEM, energy minister Amber Rudd — who campaigned to remain in the EU — has previously said the country's influence on rule changes and regulation is likely to decrease.
Membership of the IEM is likely to affect plans to increase the UK's interconnector capacity over the coming years, with new interconnections with Norway, Denmark, Belgium, France and Ireland planned.
UK utility SSE said today that the referendum outcome presents no immediate risk to its planned investments, but urged the government to outline its plans for the country's involvement in the IEM, in order to avoid a prolonged period of legislative and regulatory uncertainty.
The UK's vote to leave the EU also raises questions as to the future operation of the Irish single electricity market model, with the Republic of Ireland and Northern Ireland power markets currently conjoined independent of Great Britain. Northern Ireland will leave the EU as part of the UK.
But a UK exit from the EU may allow the UK to alter the criteria of its capacity market, which is currently technology-neutral in line with EU laws on competition.
The scheme, introduced by the previous coalition government as part of its electricity market reform, is designed to ensure security of supply and incentivise the construction of new gas-fired plants. But the first two auctions held under the scheme have procured only two large-scale new gas-fired plant projects, with carbon-intensive small-scale diesel-fired and coal-fired plants taking advantage of the technology-neutral entry criteria and gaining capacity contracts. Former energy minister Ed Davey has previously called for EU rules on competition to be altered to allow governments to favour applications for new projects over those of existing plants.
Without having to comply with EU laws on competition, the UK may be able to restrict the scheme's entry criteria to new gas-fired plant projects, which would ensure that such capacity is contracted in future auctions.
Non-EU membership may also accelerate the process of awarding contracts for difference (CFD) subsidies for low-carbon infrastructure projects, as such contracts would be unlikely to require state aid approval from Brussels before being awarded by the government.
EU state aid approval for the CFD for the UK's planned 3.2GW Hinkley Point C nuclear plant took 10 months to be awarded, while the anti-nuclear power Austrian government has since challenged the decision at the European Court of Justice. Project developer, French state-controlled utility EdF, is yet to make its final investment decision for the scheme, but said today that the UK's vote to leave the EU has "no impact" on its plans to build the plant.

Malaysia sets up cross-border renewable energy exchange
Malaysia sets up cross-border renewable energy exchange
Singapore, 17 April (Argus) — The Malaysian government is creating the Energy Exchange Malaysia (Enegem) to allow for cross-border "green electricity" sales to neighbouring countries, starting with pilot sales to Singapore. The auctioning process for cross-border sales of clean electricity will begin with a 100MW pilot run utilising the existing connection between peninsular Malaysia and Singapore, announced Malaysia's Ministry of Energy Transition and Water Transformation on 15 April. The auction will be open to renewable energy bidders in Singapore that have import licences issued by Singapore's Energy Market Authority. This pilot phase of 100MW is to "make sure that it works, and then if it does work, hopefully it can be expanded to a gigawatt level," said the chairman of the Energy Commission Malaysia Rashdan Yusof at the Atozero conference in Singapore on 17 April. "On the demand side, there will also be an auction for suppliers of renewable energy into the exchange," said Rashdan, adding that the exchange will aggregate all the renewable energy sector participants, predominantly in the solar sector, and then provide the energy to Singapore, depending on requirements such as load factors, among other things. Malaysia aims to catalyse the development of the Asean regional electricity grid and cross-border energy trading. There are "tremendous discussions" on future interconnections, said Rashdan. Malaysian state-owned utility TNB has signed six agreements with utility counterparts in Thailand, Vietnam and Laos, and has two feasibility studies planned with utilities in Indonesia and Singapore, he said, without providing additional details on these deals. There is great willingness to establish this regional power grid but one of the obstacles is that "each jurisdiction has different energy pricing systems," said Rashdan. There is a significant difference in energy pricing between Singapore and Malaysia, for example, as energy is largely subsidised in Malaysia. "These subsidies, I find, will be a core impediment in terms of the free flow of electrons," he added. "The energy exchange can level the economic and commercial playing field, so that money can flow. Once the money can flow, the electrons will flow. That's the aim of the energy exchange, to have that transparency and market-based system, without the distortion of price subsidies." There are a number of bilateral power agreements in the region, with some even crossing multiple borders, such as the Laos-Thailand-Malaysia-Singapore Power Integration Project, which connects renewable power supplies from Laos to Singapore. But Asean countries need to scale up to multilateral power trading to fully benefit from regional grid interconnectivity. Regional grid optimisation in Asean could cut the net present cost of full decarbonisation by 11pc from $7.2 trillion to $6.5 trillion, according to international classification society DNV's Asia-Pacific regional director for energy systems Brice Le Gallo last year.

BHP to expand gas-fired West Australia power station
BHP to expand gas-fired West Australia power station
Sydney, 17 April (Argus) — Australian resources firm BHP plans to increase power generation at its 154MW Yarnima gas and diesel-fired facility near the Pilbara iron ore mining hub of Newman in Western Australia (WA) state. The proposal, according to documents filed with WA's Environmental Protection Authority (EPA), will see output increase by 85MW to a total of 239MW through gas reciprocating engines and associated infrastructure with up to 120MW of nominal new capacity to be built in stages. Peak scope 1 greenhouse gas (GHG) emissions from the project are predicted to be 480,030 t/yr of carbon dioxide equivalent (CO2e), while scope 3 emissions related to supplying the gas are expected to be 37,260t CO2e/yr. Power demand at BHP's iron ore operations in the Pilbara is forecast to increase from 150MW currently to 1GW by 2040, as the company reduces its GHG emissions through electrification of its rail and mining fleets and must balance renewables with firmed generation. The iron ore mining sector is a large-scale producer of Australian GHG emissions through its Pilbara-based operations. Displacing liquid fuels such as diesel, which Australia consumes at an average rate of around 500,000 b/d by electrifying processes and switching to lower CO2-emitting sources such as gas, is expected to trend as Australia's largest polluters meet government mandates . Yarmina currently runs a 35MW diesel-fired temporary power station as part of its installed capacity. Canadian energy firm TransAlta earlier this year lodged plans to build a new 150MW gas-fired power station for BHP's Nickel West operations in WA's Northern Goldfields region. WA's domestic market is likely to be short on gas later this decade despite being Australia's largest LNG export state, the Australian Energy Market Operator (Aemo) has warned in its Western Australia Gas Statement of Opportunities. Aemo's modelling released last year shows the closure of WA's state-owned coal-fired power stations will drive increased requirements for gas-fired electricity generation in the next decade.

AES closes 276MW coal-fired power in Chile
AES closes 276MW coal-fired power in Chile
Santiago, 16 April (Argus) — US utility AES has disconnected its two Norgener coal-fired plants from Chile's national grid, removing 276MW of combined capacity almost two years earlier than scheduled. The plants in northern Chile's Antofagasta region were originally due to close on 31 December 2025. AES has 3.4GW of generation assets in Chile of which now more than half are renewable, it said. The early closure of Norgener 1 and 2, which began operations in 1995 and 1997, respectively, is part of the country's commitment to close all coal-fired plants by 2040. To date, it has closed 11 coal-fired plants with combined capacity of nearly 1.7GW, or 30pc of the 5.5GW in operation in 2019 when the phase-out plan was announced. A further four plants with a combined capacity of 873MW are scheduled to close in 2025, according to the energy ministry. A public-private decarbonization working group is developing a roadmap through 2030 to speed up the closure of Chile's remaining coal plants.

Jera targets 20GW renewable power capacity by 2035-36
Jera targets 20GW renewable power capacity by 2035-36
Tokyo, 16 April (Argus) — Japan's largest power producer by capacity Jera has renewed its renewable power output target to 20GW by the 2035-36 fiscal year ending 31 March, in line with the acceleration of its offshore wind power presence in Europe. Jera originally planned to increase its renewable power portfolio to 5GW by 2025-26 in its business plan in 2019. But the acquisition of Belgian offshore wind firm Parkwind accelerated the plan and renewable power output will be 3.4GW this year, Jera said. It last month set up a 100pc subsidiary Jera Nex in UK to achieve the new target. Jera last month won an auction to develop a 1.5GW offshore wind farm in Norway's North Sea Sorlige Nordsjo II through Ventyr, a joint venture between Parkwind and Netherlands-based Ingka Investments. The new firm is specialising in global renewable energy and will cover new projects in Norway. By Reina Maeda Send comments and request more information at feedback@argusmedia.com Copyright © 2024.
