For another year, Acciona, a leading supplier of sustainable infrastructure solutions and renewable energy projects worldwide, has revalidated its position as the “greenest” electric power generation company in the world. It has held this position since 2015 in the “New Energy Top 100 Green Utilities” ranking of Energy Intelligence, an independent consultancy that specialises in energy markets.

The ranking, which has just been published in its seventh edition, selects a hundred of the best electricity generation companies in the world and classifies them based on their CO2 emissions and installed capacity in renewable technologies (excluding hydroelectric) to determine their level of involvement in the transition to a low-carbon electric power system.

Acciona continues to be the main pure player in renewables and stands in first place in the world ranking of the US-based firm. In its report, Energy Intelligence highlights the growing role that specialised renewables companies such as Acciona play in achieving an ever cleaner energy system worldwide.

The 100 companies that make up the ranking total 3,370 gigawatts (GW) and account for around 50% of electricity generation capacity in the world. European companies figure prominently in the Top 10, with five companies, together with three from China and two from the USA. After Acciona, the greenest utilities are China General Nuclear, Iberdrola (ES), E.On (AL), NextEra Energy (US), Invenergy (US), EDP (Portugal), China Energy Investment, Orsted (DK) y State Power Investment (Ch).

An analysis of the Top 100 Green Utilities of Energy Intelligence reveals, among other things, that the companies listed had CO2 emissions below 500 kg/MWh last year (precisely 495 kg/MWh, as opposed to 565 kg/MWh in 2011).

It also highlights that, in the seven years of the study, non-hydro renewables have almost tripled in the ranking, up to 299 GW (116 GW in 2011). In this respect, Energy Intelligence emphasizes the role played by European electricity companies that have undergone greater transformations in their generation assets, adding a total of 35 GW in wind and solar in that period and divested in fossil assets to the extent of 90 GW.
