Introduction to Tata Power-Mumbai Distribution

• Tata Power - Distribution is engaged in Retail Supply of Electricity across Mumbai License area in the western region of India.

• The total spread of the license area is around 485 sq. km. and houses a population of approximately 14.5 million

• The customer base in licensed area of Mumbai city & suburbs is around 400000 • Customer base includes HT, Industrial & Commercial and Residential

consumers.

• Tata Power has installed an Automatic Meter reading system for customers in Industrial and Commercial segment as well as for energy meters installed on Distribution Transformers.

• Total Load Requirement of Mumbai Licensed area is around 1100 MW

Objective of AMR system

• To fully automate the process of meter reading and billing without any

human intervention.

• Faster detection of metering abnormalities, theft and network faults.

• Monitoring and profiling energy consumption of consumers.

• Provide load profile data to key customers on Tata Power Customer Portal.

• Facilitate accurate Load forecasting.

• Facilitate Demand Response Initiatives.

…Message Box ( Arial, Font size 18 Bold)

Induction of Itron MDM • Tata Power has deployed ITRON make MDM as a critical component of

AMR system to manage large amount of meter data and perform effective analysis of load profiles, tamper events etc.

• The introduction of MDM in AMR has helped Tata Power for seamless integration of meters with billing system.

• The load profile data and event data is analysed to identify metering abnormalities /tamper and theft of energy.

AMR Data Centre

…Message Box ( Arial, Font size 18 Bold)

Use of MDM • MDM is the central repository for data collected from all consumer meters

covered under AMR.

• The MDM system maintains repository of meter data such as interval usage data, event logs , register data & outage history.

• The data of meters which could not be read through AMR system is uploaded manually in MDM through MRI.

• Processed data from MDM is fed to SAP ISU for monthly billing purpose.

…Message Box ( Arial, Font size 18 Bold)

Functionalities achieved through MDM

A. Validation of Billing data

• In India, billing is done using meter register data. Meter register data is validated against the load profile data and is sent to billing system only if it passes validation.

• This ensures that billing data is accurate and helps improve consumer satisfaction.

• Validations like Gap Check ,Usage Tolerance, Low/high Usage Check , Register overflow check are being used.

…Message Box ( Arial, Font size 18 Bold)

Functionalities achieved through MDM

B. Analysis of Meter events

• Meters record events including tamper events as per site conditions/operating conditions. The event report has been developed in MDM which provides list of meters that have recorded a particular event (Event wise meter list).

• A report is also configured to list all the events registered by a particular meter. (Meter wise event list).

• This analysis helps in early detection of meter abnormalities and to identify tamper and theft.

• The MDMS is also used to identify meters which have recorded energy even when premise has been declared inactive.

C. Asset management

• The load pattern/ trend of Distribution Transformers and Distribution Feeders are maintained in MDMS and analysed.

• This helps to rationalise loads on distribution transformers/feeders by transferring loads from over loaded to less loaded Transformers and feeders.

• Alternately, DTs are swapped as per their capacity to areas where they can be loaded optimally to reduce losses.

D. Identifying potential participants for DR

• Load profiles of high value consumers generated through MDMS are studied and compared with overall load profile of DISCOM.

• This helps in identifying potential consumers for participation in demand response.

E. Coincident peak demand for a group of meters

• The coincident maximum demand report for a group of meters under one distribution transformer / feeder and the load factor analysis report is used to understand the loading of distribution network.

• This helps to maximize asset utilization, improve outage planning, and reduce O&M cost.

F. Energy audit

• The consumption variation report of consumer meters is compared with concerned DT/Feeder consumption pattern.

• This helps to detect meter discrepancy / energy theft.

G. Integration with Boundary Metering System (ABT)

• MDMS has been integrated with boundary metering system ( G<>T and T<>D ).

• The data of Main and Check boundary meters is compared in MDMS for each 15 minute interval to check healthiness of metering system.

• MDMS facilitates flow of boundary meter data to the Billing system and enables accurate calculation of distribution loss, AT&C loss, receiving station energy balance and feeder wise energy audit.

H. Benchmark

• The benchmarking feature of MDMS is used to define a consumption benchmark for different category of consumers and compare consumption of individual consumers with the benchmark.

• This helps in identifying the best and worst performing consumers vis-a-vis benchmark.

• This data is shared with concerned consumers to help them improve their behaviour.

I. Customer care module

• Using this module, we are providing consumption /load profiles to consumers through Tata Power customer portal.

• A “bill-to-date” functionality of the customer care module enables the consumers to estimate the bill at any time in the month based on consumption trend till date.

• Rate Analysis feature is used by the consumers to assess the impact of load shifting from one TOD slot to other through what – if analysis. This feature is used by the consumer to study the impact on cost by shifting loads to different TOD slots.

I. Customer Care Module (contd.)

• This has helped our customers to understand their consumption pattern better and plan load reduction initiatives.

• Also alerts are configured by the consumer on the customer care module as per self defined logic for exceeding preset monthly usage, demand, power factor, cost etc. These alerts are notified to consumers via SMS / e – mail.

Consumption vs. Demand Hourly average consumption for a month

J. Green button data

• The customer care module is used to provide meter data in Green Button (GB) format to consumer.

• Consumer can download his meter data in GB format, to mobile apps or web apps available in the market, to get reports on his consumption / carbon footprint.

• Detailed Analysis if required can be done based on the GB data by different 3rd party vendors available globally.
