My Electricity bill
An electric bill is a bill for the consumption of
electric energy
April
2017) Electricity is the presence and flow of electric charge.
Its best-known form is the flow of electrons through conductors such as copper
wires. Electricity is a form of energy that comes in positive and
negative forms, that occur naturally (as in lightning), or is produced (as in
generator).
Calculate Electricity Consumption - 4 Easy Steps
1.
Step. Watts Per Day. To calculate energy
consumption costs, simply multiply the unit's wattage by the number of hours
you use it to find the number of watt-hours consumed each day. ...
2.
Step. Convert to Kilowatts. ...
3.
Step. Usage Over a Month Period. ...
4.
Step. Figuring Out the Cost
Electrical
system design is the design of electrical systems. This can be as
simple as a flashlight cell connected through two wires to a light bulb or as
involved as the space shuttle. Electrical systems are groups of electrical
components connected to carry out some operation
If load
is more then supply is three phase and thus fixed charges are more.
Utilities also charge more fixed cost for incremental connected
load. Below is a screenshot from Reliance Energy bill in Mumbai: Units
Consumed: Units consumed is the number of kWh (Killo-Watt-Hour) consumed in a
month.
Total Connected
Load (TCL) is the mechanical and electrical load (in kW) that will
be connected (or to consumed) for that area. The Maximum Demand (MD) is
the total kW that contributes the total power used in one time after applying
the diversity factor based on the Total Connected Load
Using
the cost of one unit of electricity based on our current average standard
tariff (19.87p per kWh* which means 1000 watts or one kilowatt (1 kW) of
power expended for one hour (1 h) of time), we've worked out how much that's
roughly costing you.
Definition
of connected load. : the total electric power-consuming rating of all
devices (as lamps or motors) connected to a distribution system
Maximum
demand register (kW or kVA). This is the maximum power value, usually
the average of 15 minutes, reached during the billing period (this average time
may vary depending on the country). Once the value is higher than the
contracted power, the customer will pay a penalty on the electricity
bill
So when
this Light Bulb is continuously working for 1 hour, it will consume 100 Watt-hour
of energy (100 Watts * 1 hour). when it is continously glowing
for 10 hours then it would have consumed 100 watts* 10 hours i.e. 1000 Watt-hours
which means 1 kWh(kilo watt hour) or 1 unit of electrical
energy (electricity)
Demand
factor is the ratio of the sum of the maximum demand of a system
(or part of a system) to the total connected load on the system
(or part of the system) under consideration. Demand factor is
always less than one
Connected
load for electricity is similar to bandwidth and is the maximum
amount of wattage that is allocated to a house. ... Connected load is
also mentioned as sanctioned load or just load (or भार in hindi) on electricity bills
Customer
Charge - A monthly basic distribution charge to cover costs for
billing, meter reading, equipment, maintenance, and advanced metering when in
use. ... Transmission Charge - Charges for moving high voltage electricity
from a generation facility to the distribution lines of an electric
distribution company
MD is
measured in Kilowatt (kW). It is the highest level of electrical demand
monitored in a particular period usually for a month period. Maximum Demand
for any month shall be deemed to be twice the largest number of kilowatt-hours
(kWh) supplied during any consecutive thirty minutes in that month
The utilization
factor or use factor is the ratio of the time that a piece of
equipment is in use to the total time that it could be in use. It is often
averaged over time in the definition such that the ratio becomes the amount of
energy used divided by the maximum possible to be used
High
tension or HT supply is applicable for bulk power purchasers who need 11
kilo-Volts or above. Most small consumers of electricity like individual
houses, shops, small offices and smaller manufacturing units get their
electricity on LT connection
In other
words, demand, measured in kilowatts (kW), is the maximum rate of
electricity consumption over a 15 or 30 minute billing interval, as defined by
your utility. An easy analogy that is used to think of the difference between demand
and consumption is with light bulbs
The
(unofficial) term diversity, as distinguished from diversity factor
refers to the percent of time available that a machine, piece of equipment, or
facility has its maximum or nominal load or demand (a 70% diversity
means that the device in question operates at its nominal or maximum load level
70% of the time that
The
performance of a PV power plant is often denominated by a metric called the capacity
utilisation factor. It is the ratio of the actual output from a solar plant
over the year to the maximum possible output from it for a year under ideal
conditions. Capacity utilisation factor is usually expressed in
percentage
In
electrical engineering the load factor is defined as the average load
divided by the peak load in a specified time period. ... An example,
using a large commercial electrical bill: peak demand =436 kW. use =57200 kWh.
number of days in billing cycle =30 d
Explanation
of Demand Charges. Depending on how they use electricity, electric
utility customers are charged for different electric services. Along
with a basic customer charge – which is a set fee paid monthly or
seasonally – most customers pay for the energy they use (measured in
kilowatt-hours, abbreviated kWh
Electronic
bill payment is a feature of online, mobile and telephone banking,
similar in its effect to a giro, allowing a customer of a financial institution
to transfer money from their transaction or credit card account to a creditor
or vendor such as a public utility, department store or an individual to be
credited
