      <div><br>
      </div>
      <div style="text-align: justify;">December 14, 2020 &#8211; Atlantica Sustainable Infrastructure plc.- (NASDAQ: AY), the sustainable infrastructure company that owns a diversified portfolio of contracted assets in the energy and environment sectors,
        announced today that it has reached an agreement with a subsidiary of Algonquin Power &amp; Utilities Corp. (&#8220;Algonquin&#8221;) (TSX/NYSE: AQN), a diversified international generation, transmission, and distribution utility with approximately US $11
        billion of total assets, to acquire a 20MW solar plant with a 15 year PPA in place in Colombia. The project was developed and is being constructed by AAGES, Algonquin&#8217;s international joint venture.</div>
      <div><br>
      </div>
      <div style="text-align: justify;">The investment is expected to be approximately US $20 million. Closing is expected to occur after the asset reaches commercial operation, which is currently expected in mid-2021. This represents Atlantica&#8217;s first
        investment in Colombia, an OECD member country with investment grade rating.</div>
      <div><br>
      </div>
      <div style="text-align: justify;">Additionally, Algonquin and Atlantica have agreed to potentially co-invest in additional solar plants in Colombia with a combined capacity of approximately 30MW to be solely developed and built by AAGES.</div>
      <div><br>
      </div>
      <div style="text-align: justify;">Santiago Seage, Atlantica's CEO said: &#8220;We are happy to co-invest with Algonquin in these projects, in a measured step to enter into a new market like Colombia, with attractive growth prospects for renewables and with
        similar characteristics to other Atlantica&#8217;s markets in South America.&#8221;</div>
