How Open Access works?
- Electricity is generated in an offsite Renewable Energy (RE) farm
- Electricity generated from the RE farm is then injected into the State/Central grid
- The customer withdraws RE power from the grid, net of transmission and distribution charges
- The customer’s monthly invoice reflects the contribution of RE to the overall energy consumed
- Benefit of banking available in select States
- Higher displacement of fossil fuel energy {> 70%} with Central Grid connected projects
Group Captive
- A Special Purpose Vehicle (SPV) is created to power the RE project
- 26% of project equity is invested by customers
- Benefits of waiver of Cross Subsidy Surcharge (CSS) and Additional Surcharge (AS)
- Flexibility in the tenure of Power Purchase Agreement
- A minimum of 51% of the of the power generated from the RE plant must be consumed by customers to maintain captive status
Third-Party
- Zero equity requirement from the customer
- Implications of CSS and AS
- Relatively shorter PPA tenure
Both Group Captive & Third-Party structure provide green
energy benefits to customers.
How Behind the Meter (BTM) works?
- A Behind the Meter system consists of solar panels installed on the roof or on ground (within the premises) of any commercial, institutional and industrial customer
- These solutions can be with or without Net Metering
BTM with Net Metering
- A solar plant is installed in the customer’s premises
- Energy generated from the solar plant is used to meet customer consumption requirements in real time
- Any surplus energy can be fed back into the grid and drawn during non – solar hours
- Customers are only billed for the ‘net’ energy consumed by the grid
BTM without Net Metering
- A rooftop/ground-mounted plant is installed within the customer’s premises
- Normally, there are no restrictions on installed capacity
- Energy generated needs to be consumed in real time
- Surplus energy/Excess energy, if any, cannot flow back into the grid. It is restricted
