File No: GGL-IT & ERP-2026-6-181812

RFP for Selection of Implementation Agency for establishing AMI for Gujarat Energy Limited

• Any gap in metering data collection caused by AMI Platform downtime, communication

failure, software fault, incorrect configuration, or any cause attributable to the Bidder's scope

shall be the Bidder's responsibility to investigate, report, and remediate.

• For every data gap, the Bidder shall attempt recovery of missing data from the field device's

internal memory through the store-and-forward mechanism. Where full recovery is possible,

RFP for Selection of Implementation Agency for establishing AMI for Gujarat Energy Limited

recovered data shall be ingested and processed through the normal VEE and billing

workflow, clearly flagged as backfilled.

• Where data cannot be recovered from device memory — for example where the device

buffer was overwritten before connection was restored — the Bidder shall document the

cause, the affected device, the affected time period, and the estimated data loss, and shall

submit this to GEL as part of the quarterly EMS report. The affected period shall be excluded

from billable days per the SLA framework in Section 12 and shall not be invoiced.

• Data lapses attributable to GEL-directed actions, customer-side obstruction, or force

majeure events shall be classified as non-Bidder-attributable per the NMS root-cause

categorisation framework and shall not attract penalties, provided the Bidder has

documented and submitted evidence of the cause to GEL within 5 working days of

subsequently lost due to storage failure, software error, accidental deletion, incorrect

configuration change, failed migration, or any other cause within the Bidder's scope.

• Where data loss is identified, the Bidder shall notify GEL in writing within 24 hours of

detection, identifying the scope of loss — affected devices, affected time period, estimated

volume of records — and the probable cause.

• The Bidder shall restore lost data from the most recent backup within the Recovery Point

Objective defined in the AMI Platform architecture. Where data predates the most recent

backup and cannot be recovered, the Bidder shall document the irrecoverable loss in full and

submit a root-cause analysis to GEL within 5 working days.

• The Bidder shall not fabricate, estimate, or substitute metering data to fill a loss gap. Raw

data records that have been lost cannot be reconstructed; such gaps shall be reflected

accurately in the EMS and in all billing and SLA reporting.

• Irrecoverable data loss shall be treated as a Critical SLA breach under Section 12 and shall

attract the applicable penalties. GEL's right to withhold payment for periods where data was

permanently lost is unaffected by any force majeure or other contractual exclusion.

Data Theft and Unauthorised Access:

• The Bidder is responsible for preventing unauthorised access to all metering data within the

AMI System — whether at rest in the cloud database, in transit between field devices and

the platform, through APIs, or through any user interface.

• Where the Bidder identifies or has reasonable grounds to suspect unauthorised access, data

exfiltration, or a security breach affecting any component of the AMI System, the Bidder shall

notify GEL in writing within 4 hours of detection. This notification shall include the nature of

4 AMI Platform Functional Requirements

4.1 Guiding Principle

• The requirements in this Section define the functional outcomes GEL requires from the AMI

Platform. The Bidder may deliver these requirements through a unified combined platform or

through separate integrated software components — the architecture is at the Bidder's

discretion. What is mandatory is that every requirement in this Section is fully met,

demonstrated during the Field Trial/POC and sustained throughout the contractual period.

• References to "HES functionality" and "MDMS functionality" in this Section identify the

functional domain of each requirement. They do not mandate a specific product or

• All requirements in this Section are mandatory. No deviations are permitted. Any bid that

proposes alternatives to, or exclusions from, the requirements listed here shall be

considered non-responsive.

4.1.1 FRS/SRS Development

The functional requirements set out in this Section are indicative and representative of GEL's

minimum expectations — they are not exhaustive. The requirements describe what GEL

requires the AMI System to do, but they do not represent the complete or final set of functional and

system requirements for the project. The Bidder shall treat these requirements as the baseline and

shall deliver the full functional capability needed to operate a complete, billing-grade AMI System,

whether or not every individual function is explicitly listed in this Section.

• Following contract award, the Bidder shall prepare a detailed Functional Requirements

Specification (FRS) and System Requirements Specification (SRS) in consultation with GEL,

covering the complete functional scope of the AMI System, all interface and integration

requirements, data models, workflows, user roles, reports and system behaviour.

• The FRS and SRS shall expand on the indicative requirements in this Section and shall

capture all additional functional and system requirements identified during the detailed

design phase, including any requirements raised by GEL's GA Teams, billing team, IT team

• The FRS and SRS shall be submitted to GEL for review and written approval during the

Phase 2 (AMI Platform Deployment) stage, before the AMI Platform configuration is

finalised. GEL's approval of the FRS and SRS is a prerequisite for proceeding to platform

configuration and integration.

• The GEL-approved FRS and SRS shall form the binding functional baseline against which

the AMI System is configured, tested (UAT) and accepted at Go-Live. Any function

described in this Section, or reasonably implied by it, or subsequently agreed in the

approved FRS/SRS, shall be delivered by the Bidder at no additional cost.

• Where a requirement is identified during FRS/SRS development that is a reasonable and

necessary part of a complete AMI System but was not explicitly listed in this RFP, the Bidder

shall include it in the FRS/SRS and deliver it within the contracted scope. The Bidder shall

not treat the absence of an explicit listing in this Section as grounds for exclusion or

additional charge.
