HIMACHAL PRADESH STATE ELECTRICITY BOARD LTD. Brief Outline

HPSEBL – Brief Outline ü Himachal Pradesh “A Hydro Power State” ü Uninterrupted, Reliable and Quality Power Supply to all our Consumers Round the clock, 365 days a year. 3

HPSEBL – Brief Outline Our Mission: To be an active partner in the socio economic development of the state by providing quality power to all categories of consumers at an affordable price any where in the State, round the clock basis throughout the year 4

HPSEBL – Brief Outline Himachal is a hilly State with a population of around 66 lakh and the area of around 56000 Sq km with very stringent geographic & peculiar demographic conditions. The HPSEB was constituted on 1 st day of September 1971 and since then it is responsible for coordinated development of Power potential, Generation, Transmission & Distribution of electricity within the State. HPSEB was incorporated as a Govt. company in the name of HPSEB Ltd. for distribution of power on Dt. 10. 06. 2010. HPPTCL has given the status of STU in the state, however the codre control of HPPTCL and HPSEB Ltd. is with HPSEB Ltd. 5

HP’s Role from Perspective of Integrated Grid

18

19

Power Generation Scenario • Himachal Pradesh is injecting about 5600 MW power into the Grid during summer months RTC & in peak hours in winter months which is roughly 18% of the total demand of the northern region • About 3000 MW power shall be added in the period of next 2 to 3 years

Challenges • Presently the Hydro Generation is becoming highly erratic and climatic changes are becoming highly pronounced which is effecting the generation • In winter months the generation goes down to about 20% of this and power requirement is met mostly through interstate lines • During winter months the maximum power is flowing from Abdullapur-Tepla-Panchkula. Kunihar (300 MW), 220 k. V Khodri-Majri 130 MW, 220 k. V Jallandhar-Hamirpur (100 -120 MW), 220 k. V Thein-Jasoore (150 MW), 220 k. V Dehar Kangoo (80 MW)

Problems & Issues • Major chunk of power is coming from Abdullapur through Haryana system HVPNL is availing shutdown on Tepla. Panchkula line roughly on an average of 10 days in a month, which is causing great inconvenience to the consumers of HP. • Similar problem is being faced in drawl from 220 k. V Khodri-Majri line.

Low Voltage Crisis • Where as our power houses running in the grid, the voltage which is as low as 181 k. V against 220 k. V can’t be raised at our end unless & until adequate reactive power compensations is done by Punjab, Harayna & Uttaranchal. During these months we have the power but are unable to deliver it due to low voltage.

Low Voltage Crisis • HP being at remote end, the low voltage problem is highly predominant in the months of May-June-July mainly due to high reactive drawal by Punjab & Haryana. • HPSEBL has planned to add 37 MVAR capacitors for reactive power compensation in the next three months time on turnkey basis.

Need of Smart Grid Management • We need a smarter Electrical Grid , one that is prepared for real-time information, innumerable choices, quick decisions, and fast response. We’ve already seen the benefits of this in other industries. we file our taxes electronically, order books, clothes and even food online. We communicate around the world at nearly the speed of light via email. But, we still generate and deliver electricity much the same way we have done for over a century. • In this context HPSEBL has introduced the

20 th Century Grid Electromechanical/Analog One way Communications Built for Centralized Generation Radial Topology Few Sensors Blind Manual Restoration Prone to failures & Blackouts Check equipment manually Emergency decisions by committee Limited control over power flows Limited Price Information Few consumer choices 21 st Century Grid Digital Two way Communications Distributed Generation Network Topology Monitors & Sensors throughout Self monitoring Semi automated Restoration & Selfhealing Adaptive protection & Islanding Check equipment remotely Decision Support System predictive reliability Pervasive Control Systems Full Price Information Many consumer choices

Grid Operation - A collective responsibility • Transmission is an indivisible shared facility (public service) • “Failures in one location can propagate through the network”- Thomas Overbye • “Power markets are the only markets that can suffer a catastrophic instability that develops in less than a second… The extent and speed of the required coordination are unparalleled”-Steven Stoft 28
