Colombia's renewables grow, but gap looms

: Electricity
25/04/07

Development of non-conventional renewable (NCRE) generation has picked up in Colombia, but the pace is still not fast enough to cover a projected generation shortage by 2027-2028.

Colombia will likely reach 2.55GW in installed NCRE such as solar and wind — excluding large hydropower — by the end of 2025, up from 1.88GW at the end of 2024, Colombian renewable association SER director Alexandra Hernandez told Argus at the Colombia Genera conference held last week in Cartagena.

About 670MW from 19 medium and large NCRE plants worth $500mn will likely come online in 2025, Hernandez noted. Of that total, 30MW in two projects came online in January and the balance of 640MW is under construction, according to Hernandez. The plants will reduce emissions by 1.1mn metric tonnes (t) CO2/yr compared with conventional generation. For 2026, 419MW in NCRE could come online.

NCRE will comprise a 12pc share of Colombia's generation capacity in 2025, up from 10pc in 2024. But Colombia will fail to meet its target of 6GW in NCRE by August 2026, when the administration of president Gustavo Petro ends, former minister of mines and energy Amylkar Acosta said. Colombia will likely will end 2026 with 3GW, Hernandez noted. This comes despite Petro's support for renewable energy and ambitions to phase out hydrocarbons use.

Much of the NCRE development is focused on the dry, windswept department of La Guajira that borders Venezuela and juts into the Caribbean.

US firm AES' will start building the first 259MW phase of its 1.1GW Jemeiwaa Ka'I wind complex there later this year, AES's general manager Federico Echavarria said at the Colombia Genera conference.

"Our biggest bet is La Guajira," Echavarria said. Last year, Colombia's environmental regulator Anla approved a transmission line connecting 648MW of planned wind capacity in the La Guajira area to the national grid.

The 500kV Casa Electrica-Colectora transmission line and substation will connect with Grupo de Energia de Bogota's 500kV Colectora transmission line. Colectora has begun construction and should come online in 2026, a delay from its original 2022 start date.

La Guajira has Colombia's greatest renewable power potential, including 21GW of wind power potential, according to state planning agency UPME. But delays to key transmission projects and lengthy community consultations impeded development. Italian power company Enel suspended indefinitely construction of a 205MW wind farm in the Windpeschi region, but state-controlled oil company Ecopetrol is seeking authorization to buy it.

Projects advancing in other departments include the 200MW Orquidea solar project in the Caribbean province of Bolivar, which recently earned an environmental permit that clears the way for construction.

Running out of time

But this new generation capacity will not cover an expected supply shortfall. Colombia is forecast to have a gap of around 2,000MW by 2027-2028 assuming baseline consumption, and 3,000MW-6,000MW if demand rises further, several electricity associations have said.

Renewables could help fill this gap, as the construction is fairly quick once permits are secured, the renewables group SER said. But 47pc of renewable power companies were unable to complete their planned investments in 2024, with permitting delays among the top reason, the group found in a member survey.

Permits from the government's mining and planning unit UPME takes nine months, compared with the two months stipulated by the law. Regional entities take twice as long to issue a permit than the legal limit.

The government will push to do more, energy and mines minister Edwin Palma said in Cartagena.

"We are convinced and committed to ensuring that expansion projects are carried out," he said. "We will work with the ministry of the interior to expedite licenses."

EEX seeks daily Nordic power trades from 25 players

London, 16 June (Argus) — German exchange EEX believes its liquidity drive can be considered successful if around 25 participants initially close daily trades for the system and some zonal futures, sales director Tim Greenwood told Argus . The exchange has long highlighted its ambition to increase liquidity, and has now introduced specific measures to address this along with an indication of what higher liquidity would entail. EEX last week launched a package of measures to encourage activity on its Nordic offering, which covers system and zonal futures for the 12 Nordic zones. The package includes a year-long trade fee waiver scheme and clearing cost cover. The scheme is based on past successes in stimulating activity in similarly illiquid or mostly over-the-counter markets, such as Spain, Greenwood said, and will be complemented by a focus on local engagement with stakeholders. The initiative follows dramatically lower trading across its Nordic book on the year, with liquidity down by 99pc on the year in January and by 92pc in February. By delivering on its ambition to bring 25 participants onto the exchange, then rising to around 40, the exchange hopes it can demonstrate to the market it and liquidity are moving forward, so the conversation regionally can change from "what can we do" about liquidity to "how are we progressing", Greenwood said. The Nordics are primarily dominated by the state-owned utility in each country, particularly in Sweden and Norway, Sweden's Vattenfall and Norway's Statkraft. EEX is confident these participants would welcome a market that is "seven or eight times" the size it is today and that, ultimately, "the big fish go where the small fish go." EEX also hopes to demonstrate to the market its zonal futures are a tool in and of themselves for re-energising Nordic liquidity by allowing firms to trade while recognising the increasingly divergent fundamentals between zones. The Nordic system price, by papering over this divergence, has "a lot to do" with the regional liquidity decline, Greenwood said, adding the price "is not reflecting the underlying needs" of traders. The system price is part of a broader regional issue, Greenwood said, acknowledging that while participants in most other markets consider fundamentals on a market-by-market basis, the system price leads people to consider the Nordics as a whole. That is despite the Nordics comprising "different countries, with different fundamentals" and that the "ideal situation would be to focus on the different markets". EEX highlighted the system price issue by emphasising that its Danish zonal futures and their higher liquidity are representative of the problem, noting that Denmark's fundamentals and price alignment are more correlated with neighbouring Germany than the other Nordic countries. The German exchange also reaffirmed that it welcomes the competition offered by the incumbent Nord Pool-owned Nasdaq exchange, noting that until EEX's entrance, the region had "the dominance of one exchange and [liquidity] has gone down", rebutting some fears that two exchanges could further split the already low liquidity, Greenwood said. He added changes to Nasdaq clearing rules, as they come fully under the Nord Pool umbrella, provide a "bit of a wake-up [call]" to participants and a good opportunity to take advantage of EEX's "good coverage of clearing banks and cross margining", Greenwood said.

Japan’s Erex lifts biomass-fired power output in May

Tokyo, 16 June (Argus) — Japanese renewable energy developer Erex's biomass-fired power generation in May rose from a year earlier, according to data published by the company on 13 June. Erex's combined electricity output from the 50MW Saiki, the 75MW Buzen, and the 49MW Nakagusuku biomass-fired power plants in May increased by 2pc on the year to 98GWh. The company does not disclose the output of the 75MW Ofunato plant. Erex's biomass-fired power generation capacity in May was 249MW, including the Ofunato plant, with the firm burning mainly imported wood pellets and palm kernel shells (PKS). The Buzen plant was halted from 1-6 June because of regular maintenance. The 20MW Tosa plant has been shut down for an indefinite period because of aging facilities, according to the company. Erex started commercial operations at the 75MW Sakaide biomass-fired power plant on 2 June. The company plans to start up the 300MW Niigata Mega Bio around 2029-30. Erex's 20MW Hau Giang biomass-fired power facility in Vietnam came on line in April, with the plant burning rice husks. The company aims to build up to 18 biomass plants in the country, following Hau Giang. Erex also plans to start constructing a 50MW biomass plant in Cambodia in this year.

Singapore, Indonesia sign clean energy, CCS deals

Singapore, 16 June (Argus) — Singapore and Indonesia signed three new agreements on 13 June covering cross-border electricity trade, collaboration on carbon capture and storage (CCS), and setting up a joint sustainable industrial zone (SIZ). The first deal on cross-border electricity trade builds on previous agreements between the two countries, and reinforces Singapore's target to import around 6GW of low-carbon electricity by 2035 and Indonesia's goal to export 3.4GW of low-carbon power by the same year. Singapore and Indonesia will facilitate the necessary policies, regulatory frameworks and business arrangements for cross-border electricity trade within 12 months, Singapore's trade and industry ministry said. Under the second agreement on CCS, the countries will work towards a framework that would enable cross-border CCS to leverage Indonesia's abundant carbon storage potential — something Singapore lacks. Indonesia previously announced a CCS project in collaboration with BP in Papua Barat province, which aims to capture around 15mn t of CO2. And it has signed a $15bn agreement with ExxonMobil to sequester 3mn t/yr of CO2. The third new agreement supports the development of green industrial areas in Indonesia's Bintan, Batam and Karimun region — known collectively as BBK. The SIZ will incorporate low-carbon energy and battery storage, according to Indonesian energy ministry ESDM. The Singapore and Indonesia governments will invest more than $10bn in developing a solar panel supply chain, patent CCS technologies and pioneer green industrial areas, the ESDM said.

Law's sunset not an end for Argentina's renewables

Law's sunset not an end for Argentina's renewables

Buenos Aires, 13 June (Argus) — A law meant to increase renewable energy in Argentina will expire at the end of 2025 without meeting its target and with little hope of renewal, but other incentives may still bolster the sector. Law 27191, passed in 2015 to extend earlier legislation, called for renewable sources to reach at least 20pc of Argentina's energy mix by the end of its 2025 expiry. The legislation covers biogas, biomass, solar, wind and hydroelectric plants under 50MW of capacity. Renewables have expanded more than other technologies, increasing to 6,672MW of installed capacity at the end of last year from 381MW in 2003, but still far from the goal. Renewable sources accounted for 15pc of installed capacity at the end of 2024 and covered 16pc of demand, according to the state-owned energy wholesale company, Cammesa. New capacity is being added and renewables should come close to meeting the demand target — renewables covered 21pc of demand in April, according to Cammesa, and 572MW in new solar and wind capacity came online in June alone. But it is unclear what comes next as the government deregulates the economy and pulls back from market intervention. Marcelo Alvarez, head of the solar power committee for Cader, Argentina's renewable energy association, said that there is no indication six months before the law's expiration that it will be extended. "I do not think they are going to extend Law 27191," he said. "The government is not interested in anything that conditions or interferes with the free-market dynamic and [Law] 27191, with its model of quotas with fiscal incentives, goes against its ideological thinking." But the government's change in policy approach could help address some of the main infrastructure and economic problems that hampered the installation of more renewable sources. Argentina has some of the world's best solar and wind potential, according to Alvarez, but it does not have the transmission lines to get power from new plants into the grid. "The system is basically saturated and we are really going to hit a wall if we do not start to build new lines now," said Alvarez. President Javier Milei's government announced in late May a plan for new transmission lines, but the private sector would need to do the work. The plan includes 15 500kV lines that would cover 5,610km and increase the existing grid's scope by 38pc at a cost of $6.6bn. The government is also moving forward with a tender started by the previous administration for a battery energy storage system (BESS) for 500MW, one of the largest in Latin America. The winning bids should be announced in August, according to the most recent timeline. The critical point for any project is financing, which Alvarez said remains difficult and expensive in Argentina despite recent changes. He said that interest rates for a 100MW project in Argentina are around 8pc, while in neighboring Chile they can be as low as 3pc. The Milei government has started to tackle major issues, bringing inflation down to 47.4pc annualized through April from nearly 300pc in 2024, eliminating regulations on financing and exports and reducing currency controls. It also has in place an investment and legal stability mechanism, known as Rigi, to attract large-scale investment for projects over $200mn. It has awarded one power project so far, the 305MW El Quemado solar park planned by state-owned YPF. "The cost and length of financing are major obstacles," Alvarez said. "It is going to take time to lower the cost of capital."

CBAM to push renewable power export price above lignite

CBAM to push renewable power export price above lignite

London, 13 June (Argus) — Exports from renewable power production from Energy Community constituent states to the EU could cost more per MWh than exports from lignite-fired generation under the current implementation of the EU's carbon border adjustment mechanism (CBAM), Energy Community CBAM lead Peter Pozsgai said at the Energy Trading Central and South Eastern Europe (ETCSEE) conference in Vienna on 12 June. CBAM will be applied to all cross-border electricity flows from Energy Community states, including power generated from renewables. Producers will be able to deduct any payments made into a regional carbon tax or emissions trading system (ETS) equivalent — a key pillar of market coupling as laid out in 2022's energy integration package. But renewable energy producers will not pay into a regional carbon tax or ETS equivalent, and thus will not be able to deduct this carbon tax from the CBAM applied to all electricity exports. In effect, exports from renewable sources will be priced higher than those from lignite-fired plants in the Western Balkans six — Albania, Bosnia and Herzegovina, Kosovo, North Macedonia, Montenegro and Serbia. Pozsgai "hopes this can be amended" and emphasised that the Energy Community and the European Commission will hold a stakeholder meeting on 1 July with the aim of providing more clarity on CBAM's implementation. Electricity is treated separately from other physical commodities under the CBAM legislation. Carbon quantity will be based on average country-wide emissions rather than on individual plant efficiency. Each country's CO2 emissions factor will be calculated as the weighted-average emissions from all fossil fuel-fired generation in the country and is higher than the indirect emissions factor applied to other goods that are subject to CBAM when they enter the EU. This weighted-emissions factor will be applied to all cross-border power exports, regardless of generation source. CBAM loomed over discussions at ETCSEE, with the regulation being discussed on every panel over the two-day event. Market participants already have observed lower forward liquidity as uncertainty mounts on how CBAM will be implemented and expressed concern about taking financial positions while CBAM implementation evolves. But trading firms and regulators alike expressed a desire for market coupling, while acknowledging that CBAM's implementation instead may hinder regional market integration. "Regional integration is hugely important for security of supply and efficiency and should move forward regardless of CBAM, and if they meet requirements, there should be discussions of [CBAM] being lifted," according to the European Commission's deputy head of unit of the Directorate-General for Energy, Andras Hujber. "Price sensitivity will increase with the implementation of CBAM," Hungarian state-owned energy firm MVM chief commercial officer Laszlo Fritsch said. Provisions in the 2022 integration package provided a pathway to a four-year exemption for Energy Community states, provided they complete market coupling measures before CBAM's scheduled start on 1 January 2026. But no Energy Community countries have met these requirements yet. Serbia will be the first country to couple with EU neighbours Hungary and Romania in the fourth quarter of 2026, but it is unclear whether a CBAM exemption will be granted from that point forward or applied retroactively. European power transmission system operator association Entso-E earlier this week asked the EU to postpone the definitive period of CBAM to provide electricity markets with more time to adjust.
