DEFINITION OF “OPEN ACCESS” IN DEFINITION OF “OPEN ACCESS” IN THE ELECTRICITY ACT, 2003THE ELECTRICITY ACT, 2003

“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 engaged in generation in accordance with the regulations specified by the Appropriate Commission”

Salient Features of CERC Order / Salient Features of CERC Order / RegulationsRegulations

Open Access customers categorised :

Short-Term - Upto One year.Long-Term - Twenty Five years

or more

All Open Access customers to abide by Indian Electricity Grid Code.

Page 5: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

Further Classification of Open Access Further Classification of Open Access CustomersCustomers

Direct Customer – Persons directly connected to system owned

and operated by CTU

Embedded Customer – Other than direct customer

Page 6: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

NODAL AGENCYNODAL AGENCY

For Short-Term Customers– RLDC of the Region in which the drawal point

is located.

For Long-Term Customers– Central Transmission Utility (CTU)– STU of the region in which the drawal point is

located when CTU system is not involved.

Page 7: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

Responsibilities of CTU/RLDCsResponsibilities of CTU/RLDCs

Procedure for reservation of transmission capacity for short term customers including the detailed procedure for bidding within 45 days by RLDC.

Procedure and application forms for long-term customers within 30 days by CTU.

Notice of 60 days to the existing customers for applying afresh.

Page 8: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

Standardization within 60 days, the other commercial conditions for transmission charges and scheduling and system operation charges.

RLDCs to post “Open Access information” on their website within 30 days:

Page 9: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

Information SystemInformation System

RLDC to post the following on their websites within 30 days: Floor rate in Rs./MW/Day for Short-Term customer

– Regional System– Inter-Regional link– System of STU/SEB/Transmission Licensee

Status Report on current short-term customer Month-wise and year-wise report on past short-term customer Information regarding usage of

– Inter-Regional links– Links between CTU and States systems– To be updated on hourly basis and wherever feasible on 15minute basis

Average energy losses for previous 52 weeks.

Page 10: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

Processing of ApplicationProcessing of Application

For Long-Term Customers Long term access to be granted based on planning criteria.

Application for long term access should be submitted to CTU along with a Processing fees of Rs. 1.0 Lakh.

The application shall contain the details, such as capacity needed, point(s) of injection, point(s) of drawal, duration of availing open access, peak load, average load, etc.

Based on the system studies, CTU will intimate within 30 days whether or not the long term access can be allowed without further system strengthening.

Page 11: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

If no system strengthening is required, open access to be allowed immediately after entering into commercial agreements.

In case system strengthening is required required, applicant may request CTU to carry out further system studies, preliminary investigation for the purpose of cost estimate & completion schedule.

Actual extra-expenditure incurred by CTU to be reimbursed by applicant.

CTU to intimate result of studies within 90 days on receipt of such request.

Page 12: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

BPTA mandatory for long –term customers. Long-term customer cannot transfer or relinquish

his rights obligation under BPTA, without prior approval of Commission.

It may be allowed, subject to payment of compensation as determined by the Commission.

Page 13: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

Processing of ApplicationProcessing of Application

For Short-Term Customers Nodal RLDC to interact with concerned RLDCs/SLDCs to

process the same in specified time period.

Processing time as per CERC Order– Upto One Day : 12 Hours– Upto One Week : 2 days– Upto One month : 7 days– Upto One year : 30 days

Applicant to furnish details of transactions like point of injection/drawal, quantum (MW), duration, alongwith necessary payments.

Page 14: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

Approval ProcessApproval Process

Short-term open access to be allowed by utilising : (a) Inherent design margins,(b) Margins available due to variation in power flows, and(c) Margins available due to in-built spare transmission capacity created to cater to future load growth.”

In case of congestion snap bids are to be invited by RLDC. In case of transmission constraints, the short-term customers

shall be curtailed prior to the long term customers. Provided within a category, the open access customers shall

have equal priority and will be curtailed on pro-rata basis.

Page 15: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

Short- Term Open Access ChargesShort- Term Open Access Charges

A. Transmission Charges: (Rs./MW/Day)ST_RATE = 0.25 x [TSC/ Av_CAP]/365To be applied on postage stamp basis for each – Regional System– Inter-Regional link– STU/SEB or Transmission Licensee System 25% of this charges to be retained and balance 75 % to be adjusted

in the transmission charges payable by long term customer. The transmission charges payable shall be for one day and in multiples of

whole no. of days. Every transmission licensee to declare rate in Rs. Per MW per day which

shall remain fixed for one year.

Page 16: OPEN ACCESS  IN  INTER-STATE TRANSMISSION

Where TSC for any transmission licensee is not available the per MW per day charge applicable for the system owned by CTU of the region will be applicable.

Transfer capacity reservation by short-term customers is non-transferable.

In case of under utilisation , customers to bear the full transmission and Scheduling and system operation charges as per original reservation.

B. Scheduling and System operation Charges The Short-Term customer has to pay Scheduling and System Operation Charges @ Rs. 3000/- per day per customer to each RLDCs and SLDCs involved .

C. Handling and processing charges to nodal RLDC

Concluding remarkConcluding remarkEntry barriers are essential to screen genuine players and to prevent those who are only testing waters. It is required to prevent bystanders to stray into the arena. Therefore the Open access charges must not be so low as to cause a stampede. It is a service that is being offered and the compensation has to be fair and reasonable.With the opening of the flow gate there is mad scramble to get a pie of a cake which is really small which is giving rise to conflict of interests. Therefore each one must be given a fair and equitable chance to play his cards. Freedom and flexibility are required there is no doubt about it but it must be ensured that it does not become a spoke to jam the entire machinery.
