Remote maintenance Firmware Upgrade, Remote programming, which includes user to maintain the AMI system by remotely programming the system parameters like critical events, interval period, etc,. upgrading the system with new firmware

Billing System Register and Interval Billing: Register Billing Register Billing supports billing requirements for monthly billing based on register reads. It includes billing cycle data services that deliver billing determinants via an interface to CIS/Billing on the billing cycle date and on request when special reads are required. A Billing Determinant Calculator provides the flexibility to compute the billing determinant values based on utility defined formulas. Formulas are built around logical and arithmetic operators, and can contain other billing determinants, constants, and customer functions. Bi-directional : MDM should support bi-directional metering by processing the delivered and received channels for a given meter in two separate channels. Net Metering (using Virtual channel): MDM should support net metering by processing the delivered and received channels from the meter/recorder and calculating a net amount. The calculated net will be stored onto a virtual channel. MDM should provide full tracking, management, and storage of usage data related to each data channel. This allows summation of usage data separately for each data channel. Usage Calculated from Register Reads : MDM can create usage data from register reads received from AMR/AMI systems or gathered manually. MDM will calculate the difference between the current bill period register read and the previous bill period register read, applying the Current Transformer/Potential Transformer ratio (CT/PT) required converting to the correct kWh usage amount. Rollover conditions are also considered when computing usage. The calculated usage is stored in the billing table and accessible to all applications that require the data. Interval Billing: The Interval Billing should include all of the functionality offered in the Register Billing in addition to support Advanced Billing Determinants (ABD) calculated from interval reads. As interval data is retrieved by the AMR/AMI systems, the Advanced Billing Determinant (ABD) engine should process the interval reads into daily and billing cycle usage-based billing determinants (as compared to register-based billing). For example, if 15 min interval data is retrieved by the AMR/AMI system , MDM calculates the proper billing determinant which is based on RTP/ Time-of-Use (TOU) tariff, then ABD engine will make this computation based on tariff configuration data in the database. Then it stores this daily data set (RTP/TOU values with usage details for each), along with the interval data in the Metered Usage Data Repository (MUDR). On each billing cycle, the ABD engine will summarize the RTP/TOU and demand data for each period over the requested billing span and deliver these billing determinants to the billing system. By performing the billing determinant summations on a daily basis, MDM support end-user presentation of "month-to-date" information as well as spread computational.

Automatic reception of Events data /Non-Energy data like frequency voltage etc from Meter should be as given below-

S.No Requirement Details of requirement

1. Event Collection MDM receives and stores the complete meter events daily from the head-end

2. Critical Event Notification on near real time basis

3. Event Management System MDM thru workflow engine, manage the events instantaneously by routing of events to concerned dept / functions/other systems within utility. MDM further Identify irregular alerts, consumption, alarms, and other abnormal activity and should proactively generate the necessary reports, service orders, or any user defined actions, resulting in operational efficiencies. For eg: Billing System will only receive events which are business process related.

Utility shall have the option to manage the communication network, diagnose non- responding field devices remotely.

Tamper Detection features should be as follows- S.No Requirement Details of requirement

Utility detects tampering or theft at customer site

The tamper events captured by meter are sent to head-end which in turn reaches meter data management for further action. Some examples include

Meter not communicating

Meter bypasses detection

Magnet is put on meter

Physical tamper detection

Meter is removed and not reinstalled (due to reasons like Meter damaged/stolen by unauthorized person)

Notifying utility personnel for immediate site inspection: The meter data management system immediately sends high priority alerts to utility personnel for necessary action as per rules. If any discrepancy is found, a notification shall be created for a utility representative or process to analyze the tampering event and take appropriate action

Disconnecting connection: As soon a valid tamper event or malfunctioning is detected, provision should be there to disconnect the connection. Re- Connecting connection: Head-end sends the re-connect command to the meter (could be through the DCU if the solution is defined so)

Analytics in Tamper Detection TDS

TDS uses the data historian of MDM to derive various analytics for theft detection If the AMI Meter/Device is removed and re-installed, the usage pattern of the meter shall be compared with the historical usage pattern.

Prepayment Facility

S.No Requirement Details of requirement

Prepaid metering Utility through the system allows user to enroll for prepaid facility and switch from prepaid to post- paid and vice versa . Scope shall allow for following scenarios

The customer’s prepayment balance approaches zero for their site and prepays for additional electricity at Sub-Division office/other

payment systems like netbanking/credit card/debit card/wallet/USSD etc.

The MDMS system will transfer the balance automatically to the meter

firmware/implement a system so that the amount is credited based on

interval data collected by MDMS.

The customer’s prepayment balance becomes zero and emergency

credit is also exhausted if applicable and still he/she does not prepay for

additional electricity. The service connection should be automatically

disconnected by the MDMS server.

Prepayment Alerting System

Utility provides various messages alerting the customer that the prepayment balance on the AMI Meter/Device is low and time remaining before the prepaid account reaches zero. This information is passed onto the IHD (In home display) device. Facility should be there to send this information to consumers via SMS/email

Facilitating Happy Hours System facilitates happy hours when balance exhausts during holiday, or late night
