Transmission Capacity
• Is a coordinated exercise• Transmission system developed as
– Generation linked Associated Transmission System– Inter-regional schemes– Grid strengthening schemes
• Beneficiaries identified apriori– Transmission system can be constructed only with commitment
• N-1 criterion adopted• Optimum capacity• Inherent design margin available in the transmission system
– To accommodate the variation of 15% unallocated power– Skewed dispatch scenarios
• Actual margins available in the system– Generation outages, unbalanced load growth– Laws of physics prevail

Section 2 (47)Section 2 (47)
““Open access” means the non-discriminatory Open access” means the non-discriminatory
provision for the use of transmission lines or provision for the use of transmission lines or
distribution system or associated facilities with such distribution system or associated facilities with such
lines or system by any licensee or consumer or a lines or system by any licensee or consumer or a
person engaged in generation in accordance with person engaged in generation in accordance with
the regulations specified by the Appropriate the regulations specified by the Appropriate
Commission;”Commission;”
Nondiscriminatory provision for use of transmission line or distribution system or associated facilities with such line or system by any licensee or consumer or a person engaged in generation in accordance with the regulations specified by the Appropriate Commission.
Under sub-section (2) of Section 38, CTU is obliged to provide nondiscriminatory open access to its transmission system for use by
(i) any licensee or generating company on payment of transmission charges; or
(ii) any consumer as and when such open access is provided by the State Commission under sub-section (2) of Section 42, on payment of transmission charges and a surcharge thereon as may be specified by the Central Commission
“Open Access’ means
OPEN ACCESS IN INTER-STATE TRANSMISSION
• Products –
– Long term Access
– Short term Access
•Monthly
–Advance
–First Come First Serve
–Day ahead
–Same Day transactions
CATEGORY OF OPEN ACCESS CATEGORY OF OPEN ACCESS CUSTOMERSCUSTOMERS
• LONG TERM : TWENTYFIVE YEARS AND ABOVE– Life of the Assets about 25 years
– Existing beneficiaries of a regional transmission
system owned or operated by CTU- deemed long term
customers
– New Long Term Open Access customers: Require
BPTA for inter-State transmission
• SHORT TERM : WHICH IS NOT LONG TERM - Essentially a Non firm service
– The service may be curtailed if system security demands.
