While not strictly a geothermal piece of equipment, they are gaining traction in the space
I had not heard of them before. I’ve added them to the list. Thanks.
NIBE of Sweden is the company that acquired Waterfurnace WFI and also LXU’s Climate control division https://www.waterfurnace.com/assets/documents/press-release/351-160522-wfi-nibe-to-purchase-ccg.pdf
Nice…. good to have a pure-play energy efficiency company again that has GHP tech. The only thing it lacks is a dividend….
Contact Energy (CEN.NZ; 8.5TWh total generation, 39% geothermal, 44% hydro, 17% gas) and Mercury NZ (MCY.NZ; 6.3TWh total generation, 41% geothermal, 59% hydro) are the two biggest geothermal operators in New Zealand, and the only ones publicly listed. Figures are from their 2020 annual reports.
Thanks… always good to find more geothermal stocks. I’m also adding them to the list of hydro stocks.
It looks like Calpine was bought out by Volt Parent LP and is no longer publicly-traded.
Thanks for helping keep the list up to date!
