The document discusses open access regulation and grant of connectivity regulation in India. It provides definitions of open access, objectives of open access such as increasing competition and reducing losses. It describes the working process of open access involving generators, utilities, traders and consumers. It also outlines the types of open access transactions and various regulations issued over time in 2004, 2006, 2008, 2013 and 2014 that govern open access.

 It is further categorized as STOA, MTOA, and LTOA
and the duration of which depends on the
respective state open access regulations

10. OPEN ACCESS ACCORDING TO ELECTRICITY
ACT 2003
Captive generating plants [operate and maintain] have right to
open access for the purpose of carrying electricity from CPP to
destination.
1. This subjected to availability of adequate transmission facility
which is determined by STU and CTU.
2. If further disputes regarding the availability of transmission
shall be adjudicated upon by appropriate commission.
TRANSMISSION IN OPEN ACCESS
Simple accessibility of transmission lines through open access to
generating companies or License.

11. CONT . . .
• Under section 42
-> By state commission under sub section[2] of section 42 on the
payment of transmission charges and surcharges.
-> determining the wheeling charges and surcharges.
-> Agreement w.r.t supply or purchase of electricity.
-> SURCHARGES – these shall not leviable in case of OA is provided to
a person who has established a CPP for carrying electricity to
destination of his own.
DISTRIBUTION LICENSE
• Introducing OA in phases and subject to condition [cross subsidies
| operational constraints within a year]

• Mitigates off-take risk for generators
• Balance inter-regional disparities in power availability

40. Disadvantages
• Lack of adequate support from the state
government
• Pre-determined stand-by charges for open
access consumers
• Levying of high cross subsidy charges by
SERC’s and uncertainty of phase out the same
