Feasibility Studies
We carry out :
- Site and Environmental Constraints Analysis : evaluating the physical and environmental characteristics of a potential site. It includes assessing topography, soil condition, climate, and other environmental factors like proximity to sensitive ecological areas.
- Feasibility of Access to MV/HV Grid Connection : determining the practicality of connecting the energy storage system to the existing medium voltage (MV) or high voltage (HV) grid. It involves evaluating the distance to the nearest grid connection point, the capacity of the existing grid infrastructure, and the potential costs and technical challenges associated with making the connection.
- Availability of Land and Suitability for BESS Installation : we check if the land is suitable for such installations. It includes checking land ownership, zoning restrictions, and the physical characteristics of the land that might affect the installation and operation of BESS, such as flood risks or seismic activity.
- Power System Studies : these studies are essential to ensure that the ESS will operate effectively within the power system. They include load flow analysis, fault level assessments, and stability studies. These studies help in determining how the ESS will interact with the grid, the services it can provide (like peak shaving, frequency regulation, etc.), and the technical specifications required to meet regulatory and safety standards.
