Company Overview We are a sustainable infrastructure company with a majority of our business in renewable energy assets. We complement our portfolio of renewable assets with storage, efficient natural gas and transmission infrastructure assets, as enablers of the transition towards a clean energy mix. We are also present in water infrastructure assets, a sector at the core of sustainable development.
Our purpose is to support the transition towards a more sustainable world by investing in and managing sustainable infrastructure, while creating long-term value for our investors and the rest of our stakeholders.
We currently own or have an interest in a portfolio of diversified assets in terms of business sector and geographic footprint. Our portfolio consists of 28 assets with 1,591 MW of aggregate renewable energy installed generation capacity (of which approximately 90% is solar), 343 MW of efficient natural gas-fired power generation capacity, 1,166 miles of electric transmission lines and 17.5 M ft3 per day of water desalination. We own and manage operating facilities in North America, South America and EMEA. We intend to expand our portfolio, while maintaining North America, South America and Europe as our core geographies.
Our assets generally have contracted revenue (regulated revenue in the case of our Spanish assets and one transmission line in Chile). As of December 31, 2020, our assets had a weighted average remaining contract life of approximately 17 years. We intend to grow our business and our dividend to shareholders through organic growth and by investing in new assets.
