Energy / Power Monitoring System
Purpose: A System used to measure Electrical Energy / Power and other parameters
for any Feeder of an Electrical Distribution Network. For example, a Substation can
use it to monitor Incoming Feeders and all Outgoing Feeders simultaneously in Real
Time. Likewise, an Industry can monitor Grid Feeder, All Generators, and all electrical
Loads simultaneously in Real Time.
System Components:
• MFD: This System captures the Feeder Electrical Parameters using a Multi
Functional device with isolated Current Transformers. This data is captured
once every second per feeder.
• Data Logger: This captured Data is then stored in a non-volatile memory
using a Data logger. This Data logger communicates with each MFD, reads /
converts and stores the data in its memory. This acts like a Black Box.
• Server: The logged data from the Data Logger is then transferred to a
Computer / Server using Ethernet whenever the computer requests. In case
the computer is not working, then the data remains in the Data logger.
• Clients: The data in the Computer is then converted to a SQL (Database
compatible) format, by the software. This is then available to the entire Client
computer to view the Management Information Reports.
• Reports: The reports are in any time frame, from every 5 minutes to every
month. The trends are in Graphical and Tabular fashion for any Feeder or a
group of Feeders.
Necessity: Any bulk user of Electrical Power needs this System for the following
reasons:
• Central Electricity Regulatory Commission (Power Market) Regulations,
2010 requires Bulk Purchasers and Sellers of Power to intimate their
Consumption / Generation every 15 minutes one day in advance to the Grid
monitoring Authorities. In case of under or over drawl from the Grid, the User
is heavily penalized, which is inversely proportionate to the frequency of the
Grid at that instant. This requires Real Time data on the Power Generation /
Consumption for any User, and consolidation every 15 minutes.
• Availability Based Tariff will also be applicable to all Bulk Users and
Generators. The ABT regime will set the Power tariff based on various
parameters, mainly on the deviation of User drawl from the Grid, or deviation
of Generators capacity to feed the Grid. This requires Real Time data on the
Power Generation / Consumption for any User, and consolidation every 15
minutes.

• Energy Audit: This System will help in identifying Energy consumed in every
feeder in any time frame. This when clubbed with the production data; give
the Energy per unit of production at different time zones. This identifies
Energy loss in various processes, and Energy cost per unit of production.
• Real Time Energy Consumption Scenario: Any user on the LAN can see the
Energy Flow through the various Feeders at any instant. This is useful to curb
certain processes when the Demand is high or getting exceeded. It is also
useful to Maintenance Engineers to identify the faults due to over heating
and Electrical short circuits etc.
• Long Term Trending of Energy Costs: The data available can plot trends of
Energy usage over prolonged time period, which enables the User to project
future demand, and plan the infrastructure accordingly. It is also useful for
analyzing the usage of Energy if certain process parameters are changed.

The New Policy for Bulk Power Generators and Users
Under the Electricity Act, 2003 and the National Electricity Policy, the Central
Electricity Regulatory Commission makes a regulation called the Central Electricity
Regulatory Commission (Power Market) Regulations, 2010 w.e.f 20th January, 2010
These regulations shall apply to OTC markets and Exchange markets dealing in
Electricity
• Over the Counter Market
• Power Exchange Market
• Other Exchange Market
These regulations shall apply to the following types of contracts:
1. Delivery based Short Term contracts in OTC market
o OTC Contracts directly between buyers and sellers
o OTC Contracts through Electricity Traders
• Back to back deals
• Deals with Open position
• Contract to aggregate suppliers / buyers and sell / buy to a one
or more buyers / sellers
2. Financially settled electricity derivatives contracts transacted in OTC market
3. Delivery based contracts transacted on Exchange
o Intraday contract /Contingency contract
o Day Ahead contract
o Term Ahead contract
4. Financially settled electricity derivative contracts transacted on Exchange
5. Any new contracts linked with electricity generated from renewable sources
6. Any new contract in areas related to capacity, power price indices, and other
areas related to electricity
7. Capacity Contracts
8. Ancillary Services Contracts
These regulations shall apply to all market participants including
1. Grid connected entities such as but not limited to Generating companies
2. Distribution Licensees, consumers who have been granted open access
3. Electricity Traders
4. Power Exchanges and Clearing Corporations approved by the Commission
5. Members of Power Exchanges
6. Members of Clearing Corporation
7. Other Exchanges and
8. Any other transacting party

Availability Based Tariff:
Availability Based Tariff (ABT) is a performance-based tariff for the supply of
electricity by generators owned and controlled by the central government. It is also a
new system of scheduling and dispatch, which requires both generators and
beneficiaries to commit to day-ahead schedules. It is a system of rewards and
penalties seeking to enforce day ahead pre-committed schedules, though variations
are permitted if notified One and one half hours in advance. The order emphasizes
prompt payment of dues. It has three parts:
1. A fixed charge (FC) payable every month by each beneficiary to the generator
for making capacity available for use.
2. An energy charge (defined as per the prevailing operational cost norms) per
KWH of energy supplied as per a pre-committed schedule of supply drawn
upon a daily basis.
3. A charge for Unscheduled Interchange (UI charge) for the supply and
consumption of energy in variation from the pre-committed daily schedule.
This charge varies inversely with the system frequency prevailing at the time
of supply/consumption. Hence it reflects the marginal value of energy at the
time of supply.
How is ABT different from normal proceedings to determine generation tariff?
The ABT proceeding has not attempted to consider most of the cost drivers like ROE,
Operational Costs, depreciation rate, composition of the Rate Base, capital structure
etc. Proceedings to redefine these norms are being held separately. Hence the ABT
proceedings have been concerned more with tariff design rather than definition of
tariff norms or determination of tariff levels.
2. Its incidence is a function not only of the behaviour of a generator but also of the
behaviour of a beneficiary. Disciplined beneficiaries and generators stand to gain.
Undisciplined beneficiaries and generators stand to lose.
