Gujarat Electricity Tariff API

Live Gujarat coverage

Live: POST /v1/calculate · DOMESTIC_URBAN · DOMESTIC_RURAL · postpaid

What the API calculates

• Verified residential energy slabs
• Connected-load based monthly fixed charges
• Base tariff for requested consumption
• Evidence-aware, fail-closed tariff calculation

Current guarded scope: FPPAS, Time-of-Use adjustment, subsidy, electricity duty/taxes, prepaid tariff, BPL and Torrent Power are excluded. The API returns payable_complete:false where an exact utility payable bill cannot be reproduced.

Use cases

Use the Gujarat tariff API for EV charging calculators, solar savings models, EPC quotations, consumer bill estimators and tariff intelligence platforms without maintaining tariff spreadsheets manually.

Why guarded?

Electricity tariffs are more than one ₹/unit number. Monthly adjustments, applicability rules and billing context can change the payable amount. Power Expert India therefore exposes verified components and fails closed instead of silently guessing missing tariff components.

Gujarat Electricity Tariff API FAQ

Which Gujarat DISCOMs are supported?

The Gujarat tariff API supports 11 explicitly routed FY 2026-27 licensees: DGVCL, MGVCL, PGVCL, UGVCL, Torrent Power Ahmedabad, Surat, Dahej and Dholera, MUL, GIFT PCL and AIVPL.

Which residential tariffs are available?

Verified postpaid Domestic Urban and Domestic Rural tariff calculation is available with slab-based energy charges and connected-load fixed charges.

Can I use this as a DGVCL tariff API?

Yes. Use licensee_code: GJ_DGVCL with the Gujarat calculate endpoint. Gujarat uses explicit licensee codes with no automatic fallback.

Does the API return the exact Gujarat electricity bill?

No. The current release is not a claim of exact utility-bill reproduction. Verified Base FPPAS and released periodic FPPAS are included where their source-backed scope resolves. Electricity duty and any other unresolved components remain fail-closed, so payable_complete:false may still be returned.

Which Gujarat electricity tariff should be used for solar, EV and EPC calculations?

For the currently released residential scope, developers can use the verified DGVCL, MGVCL, PGVCL or UGVCL Domestic Urban or Domestic Rural base tariff according to the consumer location and category. FPPAS, ToU, subsidy, duty/tax and other excluded components must not be assumed unless separately verified.

What can developers use the Gujarat tariff API for?

Typical use cases include solar savings calculators, EV charging cost calculators, EPC quotations, electricity bill estimation, tariff intelligence software and energy procurement applications.
