Energy roundup: Priority dispatch, hydrogen strategy, transmission line, thermal plant, rate consultation

Bnamericas Published: Saturday, October 22, 2022

Argentina’s wholesale power market administrator, Cammesa, is applying a tiebreak mechanism to 34 out of 35 projects seeking priority dispatch in a round corresponding to 3Q22.

The other project – 100MW solar park Pampa del Infierno, planned for Chaco province – does not have to compete.

A final award decision is due by the end of the month.

In a context of strained grid capacity in some regions, previous rounds have typically gone to a tiebreak.

Transmission priority dispatch is assigned to projects looking to participate in the Mater term market, where generators supply power under contracts with large users. Corporates with an eye on their green credentials are driving demand for electricity from clean sources.

Argentina needs to build out transmission capacity to help support continued renewables growth in the windswept south and the sun-drenched northwest. Some transmission corridors are heavily congested, limiting the addition of new grid-connected renewables plants.

Chile’s government provided an update on work being carried out by joint ministerial green hydrogen development board H2v.

During their last meeting officials worked on aspects of the country’s green hydrogen strategy, published in 2020.

An associated presentation will be given next month during global climate crisis summit COP27. Agreements with World Bank and IDB relating to development agency Corfo’s green hydrogen project support facility will also be signed, the energy ministry said.   

The government is procuring baseline environmental studies on bird and bat populations in areas of southern region Magallanes where projects and associated infrastructure, such as power lines, could be built. Findings are due in 1Q23. 

Environment minister Maisa Rojas said the board was “working to gather a large amount of environmental information that will allow for the correct evaluation of investment projects.”

Information will allow the private sector and the authorities to take effective “protection and compatibility measures between the green hydrogen industry and nature,” Rojas said.

Gigawatt-scale green hydrogen projects involving billions of dollars in investment are planned for the windswept and barren Magallanes.

The energy ministry is seeking, in its 2023 budget, funds for territorial and land-use planning.

A major green hydrogen-related project, US$500mn wind farm Faro del Sur, was pulled from the environmental evaluation system recently after its developers alleged authorities suddenly raised the bar in terms of information requirements. The project is expected to be resubmitted. 

Power generation industry and project evaluation officials have engaged in associated talks about permitting.


Chile’s energy ministry awarded to Sonnedix Chile Holding a definitive concession to develop Atacama power line project 1x220kV line Tres Cruces-Cumbre.

The work will permit solar park Tres Cruces to inject power into the grid, a decree in the official gazette said.  


Chilean power company Cerro El Plomo sought the cancelation of an environmental license, granted in 2017, to build US$600mn, 540MW combined-cycle power station Los Rulos in Valparaíso region, broadcaster Radio Bío Bío reported.


Argentina’s electric power regulator Enre is due to hold a public consultation on 30 November on proposed rate changes put forward by transmission concessionaires Transener, Transba, Distrocuyo, Transpa, Transco, Transnea, Transnoa and Epen.

In an earlier rate review process, power transport firm officials said more revenue was required to carry out work needed to ensure service standards are met this year, to continue with associated projects and to avoid posting financial losses. Transmission charges constitute around 1.6% of a typical end-user electricity bill, with distributor rates, generation costs and taxes constituting the balance, a public consultation was told at the time.

Argentina’s government is working to trim power sector subsidies by targeting State support at lower-income households. 

Annual inflation is running at around 80%.
