The Texas Electric Co-op That Put a Battery Fleet Behind the Meter
Born to electrify farms that private utilities passed over, GVEC now links poles, fiber, thermostats and home batteries into one regional system. Its next trick is turning thousands of member-owned devices into useful capacity for the Texas grid.
Plentify
Plentify is a South African climate-tech company that builds AI-driven hardware and software to intelligently manage home energy use. Its flagship device, HotBot, is a smart controller for electric water heaters (geysers) that shifts heating to when power is cheaper and cleaner, while its SolarBot companion maximizes solar self-consumption. Founded in 2017 by Jon Kornik and Kailas Nair, Plentify links water heaters, batteries and solar inverters into a coordinated energy platform that cuts household electricity costs and eases pressure on strained grids. The company raised a roughly $15M Series A in 2025 to expand from South Africa into the UK, Australia and Brazil.
