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.
