Portugal has opted for a two-stage auction model for its inaugural offshore wind tender and has set itself time limits for launching the competitive process within six months.

Portugal is seen as a potentially attractive market for floating wind, and has played a leading role in deploying pre-commercial projects — most notably the pioneering WindFloat Atlantic array — but the premature collapse of two governments has resulted in a loss of momentum.

Delays have been aggravated by a lack of clarity over proposed dates and on whether the model will start with an auction for the seabed lease or include a pricing mechanism.

Ideas floated for support have shifted from a mix of price and qualitative factors to discussion of a UK-style contract for difference (CfD), with most developers favouring the latter.

Poorly defined responsibilities for maritime surveys, and a dearth of pre-auction studies and assessments were also highlighted among the shortcomings.
The promised launch for Portugal's first offshore wind tender is about two years behind its original ambitions.

A decree issued jointly by Portugal's energy and maritime ministries on Monday sought to regain this momentum, even though the country is less than a month away from its third general election in less than four years.

The decree, which has the technical backing of Portuguese Directorate for Energy and Geology (DGEG) and Directorate for Natural Resources, Security and Maritime Services (DGRM), confirms that Portugal will use a two-stage auction model.

The decree states that full details of the proposed tender procedure will be provided within the next 60 days, including timelines, areas to be tendered and pre-qualification criteria.

The decree, published in Portugal's official gazette, includes a commitment to identify any outstanding regulatory issues or measures required in the socio-economic sphere.

The tender will be ready for official launch, with all finalised documents in place, within 180 days, the decree stated.

Signs that the DGEG and DGRM were working hard to keep Portugal on track to launch an offshore wind tender in 2025 came in February with publication of a new offshore renewables zoning plan (PAER). It reduced some of the areas available for offshore wind, but purported to provide more certainty.

The PAER plan also reiterated a Portuguese commitment to deploy 2GW of offshore wind capacity by 2030.

The PAER plan signalled that the centre-right government led by Prime Minister Luís Montenegro was ready to pursue this target with more gusto, after forcing a review of the previous administration's offshore wind tender plan upon taking office one year ago.

But the government collapsed in March after Montenegro lost a confidence vote triggered by an ethics controversy over his family law firm.
