Utility-scale solar breaks through 500 GWp Leading EPC contractors thrive


Having started the year below 350 GW, the total now stands at 405 GWAC, representing just over 500 GWDC – that’s half of a terawatt peak.

Leading EPC contractors are thriving as the market boom continues, according to figures also published today. “American, European and Indian contractors are all doing well”, says Wiki-Solar founder Philip Wolfe; “with many again achieving record results”.

The world's top utility-scale solar constructors with over ~1,000 MWAC cumulative capacity

The main climbers at the top of the list are France’s Eiffage (now #3), McCarthy in the US (5), ACME India (6) and BayWa r.e. of Germany (12).

Spain’s Abengoa, the former world #2, has now started climbing again thanks to the resurgent local market, which has also benefitted TSK and brough Grupotec into the list. Greece’s Metka-EGN maintains its climb up the list.

Indian contractors ACME and Tata have benefitted from the continuing boom in large-scale solar projects in their home market. Chinese companies have also advanced, but continue to be under-reported in these figures owing to the lack of available data from their market.

Readers are reminded that Wiki-Solar measures capacity in MWAC including only projects over 4MWAC, so the listed PV companies have all installed comfortably over 1.25 GWP, measured by the DC solar array output. Wiki-Solar’s database includes both PV and solar thermal power plants.

Most, but not all, of the leading operation and maintenance contractors – which Wiki-Solar lists separately on its website – are companies in this top constructors table.
