Open Access GUidelines and Charges for Solar Projects in Different States
As per Electricity Act 2003 Open Access is, “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 allows large users of power (Typically having connected load of 1 megawatt and above) to buy cheaper power from the open market. The idea is that the customers should be able to choose among a large number of competing power companies, instead of being forced to buy electricity from their existing electric utility. It helps large consumers particularly the sick textile, cement and steel industrial units by ensuring regular supply of electricity at competitive rates and boost business of power bourses. Open Access can be categorized as Inter- State and Intra-State and further they can be categorized as Short term (< 1 month), medium term (3 month-3 years) and long-term (12 years- 25 years)Open access.
Buyer and seller of electricity can go for bilateral or collective transactions. In bilateral transactions, a PPA is signed between the buyer and seller. In case of collective transactions, exchange member trade electricity through exchange for a small margin fixed by the commission. Currently India has two exchanges PXIL and IEX.
Transmission charges are applicable when consumer use transmission line (33kV and above). These charges be applicable in two ways:
Inter State: Any system for the conveyance of electricity by means of a main transmission line from the territory of one State to another State (As per CERC Regulations).
Intra State: When the transmission takes place within one territory, there are certain charges payables on the basis of contracted Capacity/ Scheduled Load or actual power flow whichever is higher.
SCHEDULING AND SYSTEM OPERATION CHARGES
The scheduling and system operation charges are payable to State Load dispatch Centre (SLDS) or Regional load dispatch Centre (RLDS). In respect of Inter-State Open Access, the long or medium term customers shall pay RLDC fees and charges as specified by the Central Commission and SLDC fees and charges as specified by the Commission under sub-section (3) of section 32 of the Electricity Act. The short-term customers shall pay the RLDC and SLDC charges as specified by the Central Commission.
WHEELING CHARGES AND LOSSES
As per Electricity Act 2003, “The operation whereby the distribution system and associated facilities of a transmission licensee or distribution licensee, as the case may be, are used by another person for the conveyance of electricity on payment of charges”. Transmission and distribution network in subjected to electrical losses when used and these losses will also be bear by seller or mutual agreement.
BANKING & CHARGES
The residual electrical energy after utilization by the Exclusive/ Partly Exclusive consumer/ Captive consumption out of the injected energy in a month into the transmission and/or distribution system of Corporation/DISCOM’s, which will be utilized for its own use or for wheeling to its Exclusive/Partly Exclusive Consumer at a later time period.14
CROSS SUBSIDY CHARGES
Indian industrial and commercial consumers have been paying a higher tariff for the electricity they consume. This is in order to ensure that domestic and agricultural consumers receive power at a more affordable rate. This additional amount, known as cross-subsidy has continued under the Electricity Act, since regulators allowed to set differential tariff based on the consumer category.
When an industrial or commercial consumer decides to purchase power from an independent generator and not from the distribution licensee in that area, that distribution licensee loses the cross subsidy amount. The CS Surcharge is imposed on the consumer to ensure that the distribution licensee does not pass on this additional amount to the domestic and agricultural consumers, which can result in a steep rise in the cost of power.
