Lisbon, March 30th 2023: EDP - Energias de Portugal, S.A. ("EDP"), through its 71.20% owned subsidiary EDP Renováveis, S.A. ("EDPR"), announces an agreement with First Solar, Inc.

With this agreement, EDP increases the weight of local content in US solar PV future projects and reinforces the diversification of its procurement strategy both in terms of supply chain and technology.

EDP plans to add 4.8GWac of solar PV capacity in North America in 2023-2026 (including both utility scale and distributed generation).

First Solar's thin film PV technology sets industry benchmarks for quality, durability, and environmental performance. This technology has significantly lower CO2 footprint since its modules have the lowest carbon and water footprint of any commercially available PV module today, and excludes polysilicon from its components.

This information is disclosed pursuant to the terms and for the purposes of the article 17 of Regulation (EU) No. 596/2014 of the European Parliament and of the Council.
