Overview of Open Access in inter-State Transmission Regulations 2009
- “open access” means the non-discriminatory provision for the use of transmission lines or distribution system or associated facilities with such lines or system by any licensee or consumer or a person engage in generation in accordance with the regulations specified by the Appropriate Commission.
“long-term access” means the right to use the inter-State transmission system for a period exceeding 12 years but not exceeding 25 years.
“medium-term open access” means the right to use the inter-State transmission system for a period exceeding 3 months but not exceeding 3 years.
“short-term open access” means open access for a period up to one (1) month at one time.
A generating station, including captive generating plant or a bulk consumer, seeking connectivity to the inter-State transmission system cannot apply for long-term access or medium-term open access without applying for connectivity.
Nodal Agency – Central Transmission Utility
Filling of Application – Nodal Agency
- Application Fees: (non-refundable)
Timeframe for processing of Application:
Grant of Connectivity
- The application for connectivity shall contain details such as, proposed geographical location of the applicant, quantum of power to be interchanged and quantum of power to be drawn in the case of a bulk consumer.
- On receipt of the application, the nodal agency shall, in consultation and through coordination with other agencies involved in inter-State transmission system to be used, including STU’s if the State network is likely to be used, process the application and carry out the necessary inter-connection study as specified in the CEA (Technical Standards for Connectivity to the Grid) Regulations, 2007.
- While granting connectivity, the nodal agency shall specify the name of the sub-station or pooling station or switchyard where connectivity is to be granted.
- The applicant or inter-State transmission licensee, as the case may be, shall sign a connection agreement with the Central Transmission Utility or inter-State transmission licensee owning the sub-station or pooling station or switchyard or the transmission line as identified by the nodal agency where connectivity is being granted.
- The grant of connectivity shall not entitle an applicant to interchange any power with the grid unless it obtains long-term access, medium-term open access or short-term open access.
- An applicant may be required by the Central Transmission Utility to construct a dedicated line to the point of connection to enable connectivity to the grid.
LONG-TERM AND MEDIUM-TERM OPEN ACCESS
Criteria for granting open access:
- due regard to the augmentation of inter-State transmission system proposed under the plans made by the Central Electricity Authority.
- Medium-term open access shall be granted if the resultant power flow can be accommodated in the existing transmission system or the transmission system under execution (no augmentation shall be carried out to the transmission system for the sole purpose of granting medium-term open access).
- Applications for long-term access or medium-term open access shall be processed on first-come-first-served basis separately for each of the aforesaid types of access.
- Provided further that while processing applications for medium-term open access received during a month, the application seeking access for a longer term shall have higher priority.
- Provided also that in the case of applications for long-term access requiring planning or augmentation of transmission system, such planning or augmentation, as the case may be, shall be considered on 30th of june and 31st of December in each year in order to develop a coordinated transmission plan, in accordance with the perspective transmission plans developed by the CEA under section 73 of the Act.
- Where necessary infrastructure required for energy metering and time-block-wise accounting already exists and required transmission capacity in the State network is available, the State Load Despatch Centre shall convey its concurrence to the applicant within ten working days of receipt of the application.
LONG-TERM OPEN ACCESS
- The application shall be accompanied by a bank guarantee of Rs 10,000/- (ten thousand) per MW of the total power to be transmitted.
- While granting long-term access, the nodal agency shall communicate to the applicant, the date from which long-term access shall be granted and an estimate of the transmission charges likely to be payable based on the prevailing costs, prices and methodology of sharing of transmission charges specified by the Commission.
- While seeking long-term access to an inter-State transmission licensee, other than the Central Transmission Utility, the applicant shall sign a tripartite long-term access agreement with the Central Transmission Utility and the inter-State transmission licensee.
- Immediately after grant of long-term access, the nodal agency shall inform the Regional Load Despatch Centres and the State Load Despatch Centres concerned so that they can consider the same while processing requests for grant of short-term open access, received under Central Electricity Regulatory Commission.
- Request for renewal of term shall be submitted by the long-term customer to the Central Transmission Utility at least six months prior to the date of expiry of the long-term access.
- Relinquishment of access rights:
a) Long-term customer who has availed access rights for at least 12 years :
i) Notice of one (1) year – no charges
ii) Notice of less than one (1) year – customer shall pay an amount equal to 66% of the estimated transmission charges (net present value) for the stranded transmission capacity for the period falling short of a notice period of one (1) year.
b) Long-term customer who has not availed access rights for at least 12 (twelve) years:
customer shall pay an amount equal to 66% of the estimated transmission charges (net present value) for the stranded transmission capacity for the period falling short of 12 (twelve) years of access rights.
- The compensation paid by the long-term customer for the stranded transmission capacity shall be used for reducing transmission charges payable by other long-term and medium-term customers.
Medium -TERM OPEN ACCESS
- The start date of the medium-term open access shall not be earlier than 5 months and not later than 1 year from the last day of the month in which application has been made.
- On receipt of the application, the nodal agency shall, in consultation and through coordination with other agencies involved in inter-State transmission system to be used, including State Transmission Utility, if the State network is likely to be used, process the application and carry out the necessary system studies as expeditiously as possible so as to ensure that the decision to grant or refuse medium-term open access is made within the timeframe specified in regulation 7.
- Provided that for reasons to be stated in writing, the nodal agency may grant medium-term open access for a period less than that sought for by the applicant.
- The bank guarantee required to be given by the applicant and other details in accordance with the detailed procedure.
- Medium-term customer may arrange for execution of the dedicated transmission line at its own risk and cost before the start date of the medium-term open access.
