What open access power really costs
The headline price is not the landed price
A developer's offer of three and a half rupees a unit arrives at your meter with cross-subsidy surcharge, additional surcharge, wheeling and transmission charges, losses in transit and banking charges on energy that does not match your consumption hour by hour. Each is set by the GERC order in force and each changes. The calculator adds them up so the comparison with your own tariff is honest.
Open access or captive?
Group captive and behind-the-meter solar avoid most of these charges, which is why on-site solar with storage often beats open access for plants with roof or land. Open access wins when the site has no space and the load is large and steady. Many plants do both.
What is assumed
- Surcharges and losses at the values you set; check them against the current GERC order before relying on the result.
- Banking charges apply to the share of open access energy that does not coincide with your load.
- Eligibility is indicated on contract demand only; the DISCOM's own technical feasibility applies.
Who is eligible for open access in Gujarat?
Broadly consumers with contract demand of 1 MW and above, subject to the GERC regulations in force and the DISCOM's technical feasibility. Green energy open access rules have changed the thresholds and surcharges; check the current order.
Is captive solar cheaper than open access?
For a plant with roof or land, usually yes, because on-site generation avoids wheeling, losses and most surcharges. Open access suits large, steady loads with no space. The payback estimator covers the on-site case.
What is banking and why does it cost money?
Energy you generate or buy at an hour you do not need is banked with the DISCOM and drawn later, for a charge in kind or in cash. Storage on site removes most of the banking need.
