Different types of green energy investors covered

Our list mainly includes three different types of renewable energy investors: asset- and investment-managers, utilities, independent power producers and family offices. Asset managers are investing in the name of institutional investors and managing a renewables portfolio for their funds. That includes operating the portfolio, selling the energy through PPAs and on the free market, and acquiring new assets. Utilities are acquiring – and in some cases building on their own – renewable assets to ensure CO2-neutral and cheap energy supply for their customers. Family offices – the investment firms of high net worth families – recently started to invest in renewables and also to acquire wind and solar parks. Independent power producers are also investing in renewable energy projects – they function similar to a public utility without owning a power grid.
