Power is a commodity which cannot be stored. It has to be utilised as and when it is produced. Power is generated by the generating stations, transported through the transmission lines, and supplied to the end user by the distribution system. As power cannot be stored, efforts have to be made for the efficient utilisation of the power system and bridge the surplus-deficit gap. Thus, the concept of sale and purchase of power through various modes came into existence.
Power is measured in Watt. One Unit of power constitutes 1000 Watts supplied for One Hour. This constitutes to 1 kWH (One Kilo Watt Hour). One Mega Watt (MW) = 1000 kW It is also often referred in terms of Million Units (MUs) = 10,00,000 units.
What is Open Access? The Electricity Act 2003 defines open access as follows: "Open access means the non-discriminatory provision for the use of transmission lines or distribution system or associated facilities with such lines or system by any licensee or consumer or a person engaged in generation in accordance with the regulations specified by the Appropriate Commission.''
Open Access can be granted in case of
Surplus power of State Generating Companies. Surplus power of State Power Utilities of the State and other Distribution Licensees. Sale of Unallocated / Surrendered Power of Central Sector Generating Companies. Un-requisitioned power of CSGS. Merchandise Power Plants. Captive Power Plants for their own use. Surplus power of CPPs (Captive or Co-gen)/ IPPs. Collective transactions through exchange. Purchase of power by a consumer. Renewable power with limitation on scheduling.

Regulatory Commissions The Regulatory Commission remains the most important organization in the electricity sector after the enactment of the Electricity Act,2003.The new law distances Government from regulation and transfers all regulatory responsibilities to independent Regulatory Commissions. The Regulatory Commissions are omnipresent across the wide range of activities envisaged for the sector. They have the powers to fix tariff, grant license, regulate the performance of the licensees, adjudicate upon disputes, regulate the phasing out of Open Access in distribution and determine Open access surcharge etc.
