Power System Operation Corporation Limited (POSOCO) is a division of Power Grid Corporation of India which is under the jurisdiction of Ministry of Power, Government of India. It is responsible to monitor and ensure round the clock integrated operation of Indian Power System in a reliable, efficient and secure manner thus serving a mission critical activity. It consists of 5 Regional Load Despatch Centres (RLDCs) and the National Load Despatch Centre (NLDC).

The load despatch functions, earlier handled by PGCIL, have been entrusted to POSOCO.

History[edit]

Central Government through Ministry of Power in exercise of the power conferred by sub-section (3) of Sect 26 and sub-section (2) of Section 27 of the Electricity Act, 2003, by notification dt. 27 September 2010 in the Gazette of India notified that the Power System Operation Corporation Ltd (POSOCO), a wholly owned subsidiary of the Power Grid Corporation of India Limited (a Government Company) shall operate National Load Despatch Centre and the five Regional Load Despatch Centers, with effect from 1 October 2010.

The subsidiary was set up on the recommendations of a government committee headed by G.B. Pradhan, additional secretary in the Union ministry of power. To make load despatch centres financially self-reliant and autonomous, the committee recommended independent and sustainable revenue streams. The move to separate the two functions is in keeping with the provisions of the Electricity Act, 2003, which seeks to separate commercial interests from load management functions. The Pradhan committee report had recommended setting up a separate representative board structure overseeing the functions of the five regional load despatch centres (RLDCs) run by PGCIL—the northern, eastern, north-eastern, western and southern regions at that time. The subsidiary was eventually made a separate company effective from 3 January 2017.

Several steps were taken by Central Government and Regulators in formation of POSOCO. Some of the major milestones [1] are listed below.

• Pre 1994: RLDCs were operated by CEA with budgetary support from Govt. of India.
• 1994–1996: RLDCs transferred in a progressive manner to POWERGRID. Budgetary support from GOI stopped.
• July 1998: CEA finalized an adhoc arrangement for reimbursement of RLDC expenses (Rs. 12 Crores for 1996–97)
• 8 May 2003: CERC approved RLDC fees and charges from 2000–2001 (Rs. 21.52 Crores in the starting year)
• 2005 onwards: ULDC scheme charges merged with RLDC fees & charges and approved by CERC

The POSOCO was formed as an umbrella organization to give a corporate structure to RLDCs and NLDC with a mission to ensure integrated operation of Regional and National Power Systems to facilitate transfer of electric power within and across the regions and trans-national exchange of power with reliability, security and economy.

Mandate for Load Despatch Functions[edit]

The Load Despatch functions in India derives its mandate from Electricity Act 2003,[8] which acted as a major reform in the Power Sector for optimum scheduling and despatch of electricity. The relevant extracts of Electricity Act 2003 are listed below.

EA 2003, Section 26: “Central Government may establish a centre at the national level, to be known as the National Load Despatch Centre for optimum scheduling and despatch of electricity among the Regional Load Despatch Centres.”

EA 2003, Section 27(2): “The Regional Load Despatch Centre shall be operated by a Government Company or any authority or corporation established or constituted by or under any Central Act, as may be notified by the Central Government”

EA 2003, Section 28(1): “The Regional Load Despatch Centre shall be the apex body to ensure integrated operation of the power system in the concerned region.”

Even the National Electricity Policy 2005 [9] released by Govt. of India also put emphasis on Independent System Operation through NLDC, RLDCs and SLDCs. The relevant extract of the National Electricity Policy 2005 is listed below.
National Electricity Policy 2005, Section 5.3.7: “The spirit of the provisions of the Act is to ensure independent system operation through NLDC, RLDCs and SLDCs....”

National Load Despatch Centre[edit]

On 25 February 2009 the National Load Despatch Centre (NLDC) was inaugurated by Sushilkumar Shinde (Former Union Minister of Power) and Shiela Dixit (Former Chief Minister, NCT of Delhi). National Load Despatch Centre (NLDC) has been constituted as per Ministry of Power (MOP) notification, New Delhi dated 2 March 2005 and is the apex body to ensure integrated operation of the national power system.

Regional Load Despatch Centers (RLDCs) and the state transmission systems under them[edit]

The five RLDCs oversee the interstate transmission for the following states:

Each RLDC maintains their own dedicated website where scheduling and despatch of power within their respective control areas are handled round the clock.

POWERGRID transmission network failure[edit]

Main article: July 2012 India blackout

The Northern Region Grid, which provides power to nine states in northern India including Delhi, experienced a widespread outage due to a grid disturbance that occurred at about 2.35 a.m on 30 July 2012.

Restoration work started immediately under the direction of CEO, POSOCO and POWERGRID's chairman & managing director. A team of engineers tried to find out a way for restoring the normal supply of power immediately, so that railways, Metro, airports and other power users deemed essential could get immediate restoration of electricity. With the coordinated efforts of the whole team of engineers and constituent state utilities, power supply to the essential services and other essential loads in northern India was restored by about 8.00 a.m. and about 60% of load of the Northern Region was restored by 11:00 am. This was possible by gearing up the power supply from hydroelectric sources and also extending power from the Eastern and Western regions for start-up supply for thermal generating units of the Northern Region. Thus the associated problems for want of power supply could be partially overcome by this time. Later, power supply was restored progressively and by 12:30 p.m. power was extended to most of the cities and towns through POWERGRID sub-stations. The Northern Grid was brought back to normalcy to meet the demand of about 30 GW at 7:00 p.m.

On 31 July 2012, the northern grid collapsed for a second time, hours after the power supply was restored in the entire northern region following a disruption on the previous day. The eastern transmission lines also failed, disrupting power supply in Delhi, Uttar Pradesh, Haryana, West Bengal, Assam and Punjab, among other states.[13]

Power Minister Veerappa Moily said that transmission grids will be independently audited in three months to ensure that the grids are fail-safe.[14]
