REC Process

The entire REC process involves 4 different steps – Accreditation, Registration, Issuance and Trading. The following figure shows the order in which these steps need to be taken and the government agencies involved at each step.

Step 1. Accreditation

Through this process State Nodal Agency (SNA) authorizes or endorses the RE Generator and recommends it for registration.

Step 2. Registration

Through this process, NLDC (Central Agency) registers their Generator as ‘Eligible Entity’ for its RE Generation Project.

Step 3. Issuance of REC

Eligible RE Generator to apply to NLDC to issue the RE certificates equivalent to the amount of electricity injected into the grid as certified by the SLDC. Application can be made on a fortnightly basis, i.e., on the 1st day of the month or on 15th day of the month

Step 4. REC Trading at Exchange Platform

Trading RECs through closed double-sided auction on the last Wednesday of every month

Q. What is the annual energy generated from a 1 MW Solar Power plant?

The usual benchmark for energy generated from a 1 MW Solar Power plant is considered as 1.5 Million units. This is only a benchmark and should not be considered as the actual output for a given location. The amount of actual energy generated from a Solar Power Plant in a year depends on both internal and external factors. External factors which are beyond the control of a solar developer can include the following:

  • Number of sunny days
  • Solar Irradiation
  • Day Temperatures
  • Air Mass

  The output also depends on the following internal factors all of which are within the control of a Solar Developer.

  • Plant Location
  • Usage of Solar Tracking systems
  • Quality of equipment used
  • Workmanship of the EPC contractor
  • O&M activities

  • In case of ‘Sale of power to 3rd party’, it is mutually agreed price on long term basis through Power Purchase agreement (PPA)
  • In case of Open access; sale of power through exchange, the price depends on the exchange

It is to be kept in mind that several additional charges such as Wheeling Charges, Distribution Charges, Open-Access Charges and Cross-Subsidy Charges are Fsell recplicable in the case of sale of power to 3rd party & through open access.

Q. What are the steps involved for installing an industrial solar power plant?

Step 1: Applying for the feasibility

The developer has to apply for the feasibility to the concerned DISCOMS Chief General Manager (Comml & RAC) upto 10MW for evacuating the power to the nearest 33KV substation and get the feasibility clearance from respective DISCOM. If Plant capacity is Above 10 MW at EHT level, the application to be forwarded to Executive Director/Planning, RAC & Reforms, (TRANSCO). Along with application Bank guarantee of Rs 2 lakhs/MW valid for 24months also to be submitted.  Application Form.

Step 2: Purchase of land

After getting feasibility clearance the solar power developer has to purchase the land depending upon the capacity to be installed. The developer has to buy land based on substation proximity and geographical suitability for evacuating the power.

Step 3: Approvals

After signing the PPA concerned SE/Op-Circle will do the survey and prepare the Estimation Upto 33 kv level, or at 132 kv level CE/Construction/Discom will do the processing.

For getting approval from CGM (Com) for line survey, Estimation & Bay connectivity a request letter to be submitted to SE/OP-Circle.

A certain set of documents to be enclosed with Request letter.

    1.Copy of PPA (important as Preferential PPA projects are not eligible for REC   mechanism)

    2.Land details of the proposed plant.

    3.Plant layout.

    4.Electrical single line diagram.

SE/Op-Circle will forward the letter to DE/Op-Circle for Line survey.

ADE/Op-Circle will do the survey of line and submit the cost estimate and Line survey report to the DE/Op-Circle.

Then DE/Op-Circle will propose the cost estimate for approval of SC/Op-Circle.

SE/Op-Circle will recommend the cost estimation for approval to 1)Upto 15Lakhs SE/Op-Circle 2)Above 15 Lakhs and Upto 30 Lakhs CE zonal and3)Above 30Lakhs CGM/Com/DISCOM.

Depending on the estimation cost the respective authorities will issue the cost estimation to the developer.

The developer will request the respective authority for permission to carry out the Line Work, along with estimation copy to be submitted.

After approval from the respective authority developer has to pay 10% of estimation as supervision charges for Line erection and Bay extension in the form of DD to be submitted to SE/Op-Circle.

The developer has to approach to the Chief Electrical Inspector for CEIG approval of documents (SLD & Technical specification of major items), solar power plant, transmission line and bay system.

After getting approval from CEIG the developer has to coordinate with chief electrical inspector for getting permission to synchronisation of  the solar power plant.

After completion of all site work (Transmission Line & Bay extension) the developer has to submit to letter to CGM/Com/Discom for allowing commissioning of the solar power plant. Along with this letter 1)CEIG approval 2) lab test reports for CT/PT/ABT meters 3)Receipt of 10% supervision charges for Line and Bay work.Then CGM/Com/Discom will obtain the work completion report of solar plant, transmission line and Bay work.

Step 4:  Inspection of power plant for synchronisation

CGM/Com/Discom will form a commissioning committee with representatives from Discom, M & P, TRANSCO, Vigilance and developer. Then he will direct SE/Op-Circle to carry out the commissioning of solar power plant in presence of all committee members.

SE/Op-Circle will commission the work in presence of all the committee members.

The synchronisation committee will complete the synchronisation activity and prepares a joint report.

Then the developer has to submit request letter to CGM/Com along with synchronisation report for issuing the project completion certificate and certify commercial operation date.

Then CGM/Com will issue project completion report with conformation of date of commission for commercial operation.
