Why follow Powercube?
Powercube SMPC, a 100% subsidiary of Renel Energy & Power Engineering, is building its first energy portfolio in Grevena, Western Macedonia, Greece. This is Renel’s step from designing energy projects for others to owning and operating generation and storage of its own. Six photovoltaic stations, each pairing generation with storage: Here’s what we’re offering the people who follow along. Through Powercube’s channels, you’ll watch an energy project get built from the inside: the engineering decisions, the site work, the problems our engineers solve week to week. We’re looking to connect with European research and innovation consortia in storage, smart grids, microgrids and AI for energy. test
