Top solar Developers - Mainstream energy companies pile into utility scale solar

Most other companies on the list are traditional developers, who sell the projects when they are built; or independent power producers, who own and operate renewable energy portfolios.

Of the six solar manufacturers on the list, First Solar is tending to scale back its downstream activities, but the others – most notably Canadian Solar through its Recurrent Energy subsidiary – use new project development as a market for their output. The former developer SunEdison continues to feature as other complete the projects it initiated before its collapse.

India’s Acme Solar is amongst the highest climbers in the owner’s list thanks to its new develop- ments in 2018/19. Similarly, international IPP’s such as Scatec Solar, Enerparc and Neoen are progressing thanks to their project development activities.

While most of the leading plant owners also develop projects, a few acquire most of their capacity from others. This applies, for example to US-based Global Infrastructure Partners, now at number 3 in the list and the UK’s Actis, a major climber to number 22.

Wiki-Solar’s lists are built from the bottom up – totalling the capacity of utility-scale solar projects on its database. Founder Philip Wolfe points out that “this means the contributions of some – both on and off the list – are understated, because not all partners in all projects are known, though many leading companies keep us informed”. It should be noted that these lists total only commissioned projects for which the companies acted as project developers or owners. Many of those listed also act as EPC contractors or in other roles and may be responsible for more overall capacity than is shown here.
