Slide 2: NEW TRENDS OF ELECTRICAL POWER INDUSTRY
OPEN ACCESS & DE-REGULATION
M.TECH (POWER SYSTEM)
Roll No.-08304EN023 WELCOME TO ALL OF YOU Slide 3: Present scenario of Indian electric power industry
How can we manage power system efficiently?
Electricity act 2003
Concept of open access
Why open access?
De-regulation in power system
Effect of De-regulation
Role of regulatory commission WHAT I AM GOING TO PRESENT- Slide 4: Present scenario of Indian electric power industry Slide 5: RECENT INDIAN NETWORK DATA Slide 6: GROWTH IN TRANSMISSION LINE Slide 7: FEATURES OF THE ELECTRICITY ACT, 2003 An Act relating to generation, transmission, distribution, trading and use of electricity to development of electricity industry, promoting competition, protecting interest of consumers and supply of electricity to all areas, rationalization of electricity tariff, ensuring transparent policies regarding subsidies, promotion of efficient and environmentally policies constitution of Central Electricity Authority, Slide 8: WHAT IS OPEN ACCESS? One of the significant provisions of the Electricity Act is “OPEN ACCESS”.
Open Access” means the non-discriminatory provision for the use of transmission lines or distribution system or associated facilities with such lines or distribution system by any licensee or consumer or a person engaged in generation in accordance with the regulations specified by the appropriate Commission. Slide 9: To invite private sector to invest in the power industry
To promote competition among the generating companies
To facilitate consumers to buy power directly from generators
To lead to availability of cheaper and reliable power supply WHY OPEN ACCESS? Slide 10: CATEGORY OF OPEN ACCESS- (i) Long term open access user
Open access agreement for more than 2 years.
Nodal agency – State Transmission Utility (STU)
(ii) Short term open access user
Open access agreement for less than or = 1 year.
Nodal agency – State Load Dispatch Centre (SLDC). Slide 11: Ensuring the capacity in transmission and distribution system
Creating a multi buyer/multi seller environment
Determining cross-subsidy surcharges based on economic principles
Determination of transmission/wheeling prices
Determination of rules and regulations for power trading
Categorizing the consumers as LTOA and STOA
and determining the charges based on category
Determination of priority depending on category and congestion KEY ISSUES FOR OPEN ACCESS- Slide 12: Gives freedom to user to buy power from any suplier
Assessment of Transfer Capability
Methodology for transmission charge sharing
Treatment of transmission losses
Transparency and non-discriminatory implementation
Congestion management ADVANTAGES OF OPEN ACCESS- Slide 13: Deregulation in power sector is a process by which
government remove or reduce restriction
on power industry and invite private sector
to invest in the power industry. WHAT IS DE-REGULATION? Slide 14: Generation Transmission Distribution Electrical Power System Slide 15: Power industry is undergoing restructuring throughout the world.
The traditional vertically monopolistic structure has been deregulated
and replaced by Gencos, Transcos and Discos with competition
introduced to Gencos and Discos in order to reach higher efficiency
in electricity production and utilization.
A lot of power markets have been established for the purpose. WHAT IS DE-REGULATION ? Slide 16: INITIAL SET UP GENERATION
SINGLE MANAGEMENT Slide 17: RESTRUCTURED SET UP OF DEREGULATION GENERATION
COMPANY-1 GENERATIONCOMPANY-2 GENERATION
COMPANY INDEPENDENT POWER REGULATOR Slide 18: Deregulation Deregulation Scheduling Coordinator ISO Transmission Owner Utility Distribution Company Generator Generators and Utilities Energy Service Provider Power Exchange Slide 19: To attract various investments to power systems through
open-access and fair competition so that power supply
can meet the fast growth of demand in developing countries.
To reduce government commitment to power industry,
To encourage efficient electricity production and
utilization through competition and electricity pricing
So the purpose of de-regulation or in practical term re-regulation
is to re-structure the Indian power network so the power generation
can reach to customer in a competitive way under regulatory
framework WHY DE-REGULATION? Slide 20: Effect of Deregulation Monopolistic
Power Market Competitive
Power Market Cost reduction Problems to Solve Security problem due to the nonutility companies Need of Actual Transfer Capability Analysis Need of Exact Model of Power Systems
Under Deregulated Environment Slide 21: To determine
Transmission and Distribution wheeling charges
Surcharge considering the current level of cross-subsidy
in the area of the distribution.
The manner of payment and utilization of above surcharge
the use of common network by different generating companies
or customers is made possible by different laws by regulators ROLE OF REGULATORY COMMISSION Slide 22: Electricity reform process in India is already in action although in a slow
Pace, several state electricity boards are being unbundled into three
separate corporations namely Gencos, Transcos and Discos.
The distribution system is privatized for better efficiency in metering,
billing and revenue collection.
The distribution company has option to purchase power from any
generation utility through the existing transmission network
We can say that open access and de-regulation make the power system
more reliable, efficient and flexible.
The open access market can improve the Indian power industry and
Indian economy also. Conclusion
