GOO auctions to help Portuguese power retailers: Acemel

  • Spanish Market: Electricity
  • 08/07/21

Portugal's recently unveiled auctions for guarantees of origin (GOOs) from subsidised renewable generation will help local power suppliers by aggregating liquidity in a market that is otherwise very fragmented, energy retailers association Acemel president Ricardo Nunes said.

Auctions will be periodic, starting with a first tender on 28 July for a total of 3.42TWh split among wind, hydro, thermal and solar products generated in August-September last year and April this year, Portugal's general directorate of energy announced this week. The volume represents almost half of the total renewable power generated in the country in those three months.

Acemel asked in recent years for measures to improve liquidity in the local GOO market, and auctions are a good option, Nunes told Argus today.

"Currently, liquidity is spread over several brokers and generators, so auctions will aggregate volumes," he said.

Local power suppliers usually engage with multiple renewable producers, traders and brokerage firms to assess the market whenever they want to buy or sell GOOs, according to Nunes. While this will continue in the case of GOOs from non-subsidised renewable generation — around half of the total renewable output in Portugal — the periodic auctions for subsidised renewables will create a separate platform aggregating relevant volumes available for local retailers and other participants to bid, he said.

Retailers will also benefit from Iberian energy exchange Omip running the auctions, as they are already used to the exchange's platforms in their operations to buy and sell power futures contracts, Nunes said, including other auction systems such as the one for the sale of power futures to mainland Portugal's last-resort supplier, SU Eletricidade, a subsidiary of utility EDP formerly known as EDP Servico Universal.

‘Unfair' competition from regulated power prices

The GOO auctions are good news for local retailers, which have been facing tough conditions in recent months thanks to record high power and gas prices in Iberia and elsewhere in Europe.

Omie day-ahead prices in Iberia reached the highest for any quarter in April-June this year, while June delivered at the highest average price for any month, as lower-than-average hydropower reserves compounded the spikes in European gas and emissions markets. June delivered at €83.30/MWh in Spain, up from €67.12/MWh in May and €65.02/MWh in April to make an average of €71.76/MWh for the quarter. The June price surpassed the previous record of €73.03/MWh in September 2008 by more than €10/MWh and was above the highest assessment for the June over-the-counter contract at €79.25/MWh on 26 May.

And both Omie delivery prices in July and futures contracts for delivery throughout the rest of this year have been higher than €90/MWh, with some contracts even trading above €100/MWh in recent sessions.

Portuguese retailers have been forced to pass on the price increases to their customers while facing "unfair" competition from SU Eletricidade, whose regulated prices are set at least once a year by the country's energy regulator ERSE, Nunes said. The price for 2021 was set late last year at €49.52/MWh and revised up last month but by only €5/MWh, which is "insufficient" considering current and futures prices, according to Nunes.

"What we are seeing is a subsidised dumping from the regulated market, which worries us in the liberalised market," he added.
