Eligibility conditions same as MTOA

For LTA applicant:(i) already be connected to grid, whether the State grid or the inter-State grid,(ii) have already been granted permission for connectivity to the grid

(iii) have already applied for connectivity to the grid

(iv) be making application for connectivity to the grid simultaneously withthis application in line with the Regulations

May require Transmission augmentation

Provision of target regions in case PPAs(purchasing entities) not firmed up

applicant shall have to firm up exact source of supply or destination, as thecase may be, at least 3 years prior to the intended date of availing long term

access at least for a capacity equivalent to 50% of the quantum of power forwhich LTA has been sought for through signing of PPA with such gridconnected entity(ies)/ State Utilities.

LTA PROCEDURES


54/63

The augmentation of the transmission system as identified for grant of LTAshall be undertaken only after fulfillment of above condition. In case acommon system augmentation/strengthening has been identified for morethan one generator, then the above condition of signing of PPA for at least

50% of LTA sought for, with the grid connected entity(ies)/ State Utilities,shall have to be met by all the generators.

In the event of failure of any generator meeting above condition of 3 yearsprior to the intended date of availing long term access, the implementation ofaugmentation/strengthening of system shall be undertaken in dueconsideration of the same and if necessary with the approval of CERC for the

same.(Grant of regulatory approval for execution of ISTS schemes to CTU)

For the balance capacity (not exceeding 50% of LTA sought for) for whichexact source of supply or destination could not be firmed up on long-term

basis, the augmentation/system strengthening further from the target regionshall be taken up only after identification of exact source/destination. CTUshall be allowed up to 3 years time for such augmentation/systemstrengthening from the target region to the exact source/destination. During

such period the applicant shall be liable to pay the transmission charges up

to the target region.

LTA PROCEDURESP t f h t i i h f th b l it f hi h


55/63

Payment of such transmission charges for the balance capacity for whichexact source on long term basis is not known, shall not entitle the applicantany right over the transmission system up to the target region and CTU mayrelease this balance transmission capacity up to target region for short-term

open access or the medium term open access till the applicant firms upsource/destination on long-term basis and its operationalisation.

However, applicant may seek short-term open access or the medium termopen access separately till such time it gets long-term access for the balancecapacity as any other short-term open access customer or the medium termopen access customer.

As it takes about 9 months for pre-investment activities and in additionconstruction time for the transmission project as given in the CERC (Termsand Conditions of Tariff)Regulations, 2009, applicant should expedite the

finalization the beneficiaries and intimate to CTU. The date of commencementof LTA shall be applicable from atleast 3 years and 9 months (9 months timerequired for project preparation and investment approval) from firming upbeneficiaries and signing of BPTA/TSA with them.
