Tenaska’s development services arm, Tenaska Solar Ventures, will work alongside Acciona on project development.

The new solar plants will plump Acciona’s North American renewables portfolio, which is currently heavily weighted towards wind. The Spanish firm's US solar activity is currently limited to a 64MW concentrated solar plant (CSP) in Las Vegas.

Rafael Esteban, Acciona's North American energy division director, said that the new solar and storage capacity will give the company the “opportunity to increase our commitment to renewable energy and sustainability in the United States through photovoltaic and energy storage technology, after the investments we have already made in wind power.”

In a statement, Acciona said it counted 1,207MWp of solar capacity worldwide at the end of the first quarter of 2019.

Nebraska-based Tenaska is no stranger to inking megadeals. In November 2018, the Nebraska-based IPP signed an agreement with Swiss asset management company Capital Dynamics to develop 2GW of solar across the Midcontinent System Operator (MISO) market.

US solar prospects will take centre stage at Solar Media's Solar & Storage Finance USA, to be held in New York on 29-30 October 2019.
