The Macri Administration has made renewable energy a priority in its energy policy. Since July 2016, when renewable sourced energy amounted only to 0,8 GW (1,8% of the energy matrix) the government has launched three “rounds” of power auctions, Renovar 1, 1.5 and 2, which led to the award of 147 projects in solar, wind, biomass and other renewable sources representing 4.466,5 MW at an average of US$ per 51,49 MWh in the last round. Still, only a few of these projects have been commissioned, while many others have experienced delays. Increased financing costs tied to Argentina’s macroeconomic problems and a severely constrained infrastructure (the high-tension 500KV transmission lines are at full capacity) have hampered the renewable energy sector. With RenovAr 3, or“MINIREN” as it is popularly referred to, the government has taken a necessary steptoward achieving its goal of having 20% of national energy consumption sourced from renewables by 2025.

Tweaking the Rules for 400KW

MINIREN calls for the tender of 400KW. While sharing the aim of encouraging renewable energy projects, MINIREN differs in a number of ways from the preceding RenovAr rounds:

  • MINIREN projects will use available transmission capacity in nearby mid-tension grids of 13.2, 33 and 66 KV. This is a workaround to the saturated 500KV transmission network.
  • MINIREN goes small. Each project is limited to a maximum output of 10 MW (and a minimum output of 0.5MW).
  • Solar and wind combined. MINIREN will award competitive contracts by applying identical criteria to solar and wind projects. These two sources will compete as equals for a maximum of 350 KW. Additionally, solar and wind projects may not exceed 20MW per province, except in the Province of Buenos Aires, where projects may, in the aggregate, reach 60MW.
  • 50 MW will be allocated to other renewable sources. MINIREN reserves these 50MW for the remaining renewable technologies and, among them, allocates 5MWfor “PAH” (small hydro-electric), 25MW for biomass, 10 MW for biogas and 5 MW for biogas from landfills.FormatThe government has indicated that bidding terms will be released to the public in October with a tentative timetable calling for bids in March 2019, awards in May 2019, and signing of the power purchase agreements in July 2019.As in the previous rounds, successful project bidders will enter into PPAs with CAMMESA (the quasi-government manager of the wholesale electricity market). The PPA obligations will benefit from the FODER trust created by the government to promote renewable energy. FODER coverage guarantees generators three months’ of power purchasepayments. In addition, the projects will be eligible for various tax benefits.

MINIREN reflects the government’s commitment to renewable energy and desire to learnfrom its mistakes. The third round should attract smaller players to the renewable energy market and, by using existing available transmission capacity, will allow projects to overcome the infrastructure constraints that hindered projects awarded under prior rounds. The race to achieve the 20% goal of renewable source energy by 2025 is still on.
