Round-the-Clock (RTC) / Firm Green Renewable Energy (RE) Hybrid Power Plants represent the next evolution in clean energy systems—designed not just to generate renewable power, but to deliver it reliably, continuously, and on demand. By integrating Solar Photovoltaic (PV), Wind Energy Generators (WEGs), Battery Energy Storage Systems (BESS), and optionally grid or other dispatchable renewable sources, these plants ensure a stable and firm power supply profile comparable to conventional baseload generation.
By combining complementary resources—solar for daytime and wind for evening/night—along with energy storage, RTC hybrids effectively overcome intermittency. BESS stores surplus energy and supplies it during peak demand or low-generation periods, ensuring uninterrupted and contract-compliant power delivery. RTC hybrid plants are widely adopted for utility-scale projects, industrial decarbonization, and reliable clean power supply under long-term PPAs.

Performs detailed hourly Global Horizontal Irradiance (GHI) and Plane of Array (POA) Irrandiance calculation by evaluating actual factors like solar time, hour angle,
declination, Zenith Angle, Solar Azimuth and angle of Incidence using the inputs tilt angle, tracking, Direct Normal Irradiance (DNI) and
Direct Horizontal Irradiance (DHI). (DNI & DHI are obtained from site solar hourly data generated by module.)
Using this hourly GHI value & POA Irradiance, hourly PV electricity generation is worked-out.
Similarly, the hourly wind speed and air density data generated by module, along with wind turbine input data (Rated Power,
Rated Speed, Rotar Diameter, Hub Height, cut-in/cut-out speeds, OEM power curve), are used to calculate wind shear exponent,
wind speed at Hub Height, density correction, Coefficient of Performance (Cp) and hourly wind electricity generated.
Based on the wind shear exponent value, the site terrain is validated. Based on the wind speed at Hub, module establishes Site Wind
Classification and Turbulence Classification as per IEC 61400-1, which will help in selecting correct wind turbine generator for the project.
Solution module intelligently balances charging and discharging sequence based on power demand/delivery options namely Peak Shaving/Renewable Firming and accordingly establishes
annual charging cycles to evaluate the battery replacement life.
