P.D.S. manages solar, wind, and hydro energy project developments, Estimate foregone energy. We assist client on IESO dispatch and outage management. We manage operational renewable energy facilities on monthly basis; prepare operational & production reports, Real time market operations and asset and resource optimization, site audit. We perform modelling assessment, use energy models i.e.  PVSys, Meteonorm, WAsP, Meteodyn, and CFD modeling

If your business emits contaminants to air, PDS helps to resolve your facility air quality issues and how to comply with the local air quality regulation. We perform Emission Summary and Dispersion Modelling  (ESDM) Report  and complete dispersion modelling assessment for your facility (i.e. CALPUFF, AERMOD, ASHREA, and meteorological model (e.g. WRF))
