TEWA Solar x NR Flex
A solar-plus-storage project only pencils out when its business case and its engineering are equally solid, and that is exactly how TEWA Solar and NR Flex complement each other. NR Flex is a consultancy fully dedicated to large-scale battery storage: market and revenue modelling, business-case structuring, development and owner's engineering. TEWA Solar brings the engineering execution that turns those projects into operating assets: HV substations, grid connection, PV and storage design, commissioning and SCADA. Together, through a long-term partnership, we cover the whole solar and storage value chain under one roof, from business case to a fully energised, revenue-generating plant.
TEWA Solar x DSI
As TEWA Solar's 'little brother' in terms of expertise, DSI (Dynamique Solaire Ingénierie) brings field-proven know-how on photovoltaic installations. Victor SALVY worked with TEWA Solar founder Hervé KLEISS on the Karavasta and 20 MW BESS projects. Both companies share the same DNA: technical and operational excellence.
