Green Open Access Eligibility and Landed-Cost Report

Illustrative screen of a 5 MW round-the-clock green supply for an industrial consumer in Maharashtra

Exchange: Power Trading
Prepared for: Sample Energy Ventures Pvt Ltd (illustrative)
Prepared by: BARREL Digital Exchange desk

1.Consumer facts (as declared)

State: Maharashtra
Consumer category: HT industrial, steel plant, Raigad district
Sanctioned load: 7,500 kVA
Supply voltage: 33 kV
Contract demand: 7,000 kVA
Annual consumption: 48.6 million kWh from 12 months of bills (self-declared)
Average drawal: About 5.8 MW; night load close to day load
Existing arrangements: No open-access, captive or group-captive supply today (self-declared)

2.Eligibility screen

Green open access is available to a consumer whose contracted demand or sanctioned load is 100 kW or more. At 7,000 kVA this consumer clears the threshold many times over, so the question is not whether it qualifies but on what terms the state's green open access framework applies to it.

100 kW threshold: Passed: contract demand 7,000 kVA
Connection level: 33 kV, intra-state; both the transmission and the distribution network are used
State notes: Charges are set yearly by the state regulator; banking of green energy is allowed within limits against a charge in kind; no outstanding dues may be pending; a standby arrangement with the DISCOM is advisable
Metering: 15-minute interval metering at the 33 kV point is required; the present meter is to be confirmed

3.Supply option considered

Source: Illustrative Hybrid Power Co., intra-state portfolio (indicative offer)
Technology: Solar and wind with battery storage, pooled by the seller to a 5 MW round-the-clock schedule
Delivery point: Consumer's 33 kV metering point via the state transmission and distribution network
Term: 15 years, with a review of the delivered profile after 12 months
Contracted energy: 5 MW in all blocks: 43.8 million kWh a year at 100 percent; 37.2 million kWh at the 85 percent delivery assumed here
Renewable attributes: Transferred to the consumer

4.Landed-cost build-up (illustrative, ₹ per kWh)

Figures are rounded, use charge levels typical of a 33 kV intra-state consumer and are for screening only. The two surcharge lines change with each tariff order and may be reduced or waived for green supply; the energy charge is the seller's indicative offer, not a contract price.

Component	₹ per kWh	Basis
Energy charge at the delivery point	3.85	Seller's indicative round-the-clock offer
Transmission charge (state)	0.30	Capacity charge spread over 37.2 million kWh
Wheeling charge (DISCOM, 33 kV)	0.25	Current schedule, illustrative
Cross-subsidy surcharge	0.90	Illustrative; may be lower for green open access
Additional surcharge	0.45	Illustrative; may be reduced in some cases
Transmission and wheeling losses	0.18	4.5 percent in kind, valued at the energy charge
Banking	0.06	8 percent in kind on the 20 percent of energy assumed banked
Scheduling and operating charges	0.03	Load despatch and agent fees, illustrative
Landed cost	6.02	Sum of the above, before electricity duty and taxes

5.Comparison with current tariff (illustrative)

The 11.4 million kWh the plant uses beyond the assumed delivery, and any shortfall in the delivered profile, continue to be bought from the DISCOM at the current tariff. The difference shown is on the contracted energy only and narrows if the seller delivers less than assumed.

The two surcharge lines are the largest uncertainty: together they are ₹ 1.35 of the ₹ 6.02. They are revised with each tariff order and the treatment of green open access differs by state and by year, so the screen should be rerun on the order in force when the application is filed.

A round-the-clock profile from solar, wind and storage depends on the seller's storage dispatch and on banking being available in the shape assumed. Standby power during outages and the balance drawal above 5 MW stay with the DISCOM; the cost of standby and of any deviation charges is not included.

Item	Current DISCOM supply	Green open access option
Energy charge, ₹ per kWh	8.10	6.02 landed
Fuel and power purchase adjustment	0.40	Not applicable to open-access energy
Effective energy rate, ₹ per kWh	8.50	6.02
Demand charges on 7,000 kVA	Paid to the DISCOM	Still paid to the DISCOM; unchanged
Electricity duty and taxes	Applied	Applied on the same basis; excluded here
Annual cost on 37.2 million kWh	₹ 31.6 crore	₹ 22.4 crore
Indicative difference	—	About ₹ 9.2 crore a year, before standby, deviation and balance-drawal costs

6.Next steps

1. Consumer: Share 12 months of bills and the sanctioned-load letter for a document check; confirm the 15-minute meter
2. Seller: Confirm connectivity status and delivery-point feasibility with the state transmission utility
3. Both, under NDA: Exchange block-wise load and generation profiles; BARREL's desk issues an indicative term sheet, then a counterparty credit review and the form of credit support
4. Open access: The consumer, or its authorised agent, files the application on the state portal with the DISCOM's intimation
5. PPA: Negotiate with legal advisers in the deal room; scheduling and settlement by the authorised parties after signing
