MithraSol specialises in the identification, development, construction and operation of Spanish solar photovoltaic assets and currently has 50MW of assets in development across twelve projects spanning central and southern Spain. The first of our phase one Spanish power plants began feeding electricity into the Spanish grid during Q1 2022 with the second connected and the third broken ground early Q2 2022. We have a deep network of contacts within the region which it is leveraging to identify, evaluate and acquire a significant pipeline of high quality development stage assets.
