Amazon, Google, Microsoft, Facebook and other big-hitters have slammed EU governments for ignoring corporate renewable power deals in vital clean-energy plans.

The tech giants joined major energy groups such as Iberdrola, Enel, Orsted and E.ON by signing a letter to EU energy union commissioner Maros Sefcovic demanding he raises the issue with member states when he responds to their draft National Energy and Climate Plans, which set out how they plan to help get the bloc to its target of a 32% renewable energy share by 2030.

The letter says clearing regulatory barriers to corporate renewable PPAs – where companies sign long-term contracts to buy wind or solar output – is specified in the EU’s new Renewable Energy Directive as mandatory for member states.

But the issue is ignored in draft plans submitted by the 28 EU nations, say the 50 companies that signed the letter. “Unfortunately, only two of the draft National Energy and Climate Plans even mention corporate renewable PPAs, and none comply with the agreed legislation.”

The letter urges Sefcovic to respond to the draft plans with “clear, actionable, and country-specific” recommendations on corporate renewable PPAs.

“Getting this right could unlock significant corporate demand for green electricity, said the companies in the letter, sent under the banner of the RE-Source corporate sourcing platform, made up of WindEurope, SolarPower Europe, RE100 and WBCSD.

RE-Source is pushing to aid a higher uptake of renewable power by corporates as they focus on green targets and look to lock-in stable, competitively priced power supplies.

Corporate PPAs have been slower to spark in Europe than in the US, but RE-Source said more than 16GW has been contracted over the last five years either through power deals or direct onsite generation.

The National Energy and Climate Plans have to be finalised by the end of 2019.
