Energy bills can be complicated and mysterious. While the cost of apples (for example) is the number of apples times the price per apple, utilities slice and dice their energy "apples" (or units) in a variety of ways. And many utilities don't make it clear how much their whole apples cost you (they instead tell you the price for every little slice).

The purpose of this article is to help you understand your Cobb Electric Membership (Cobb EMC) energy bill. So you can take control and cut it. The next article in the series will show you quick and easy ways to cut it.

**Quick note**

This article is focused on your *electric* bill. When we say energy, we mean electricity. The article doesn't consider natural-gas heating.

A "Tiered rate plan" is a rate plan where the amount you pay per kWh for electricity increases as the quantity of electricity consumed increases. Generally there is a baseline allowance of a certain number of kWhs (kilowatt hours) per month that are charged at a cheaper rate, and then usage above this allowance is charged at a higher rate.

A "Time-of-Use" rate plan is an electricity plan where the amount charged per kilowatt hour (kWh) is determined by the time of the day and the season of the year in which it is used.

Time-of-Use plans will typically have "peak" periods with higher rates and "off peak" periods with lower rates.

The idea behind time of use billing is to get customers to use less power at peak periods (when most people use a lot of power). Peak periods put a lot of strain on the grid. This is why time of use billing is being implemented by all major utilities. It is an attempt to encourage consumers to help spread out the load, and thus reduce investment needed to support brief periods of extremely high usage.

If customers can adjust their habits to use appliances at non-peak times they have the potential to significantly lower their electricity bills. Although, as power at peak times is much more expensive, if you continue to use lots of power at peak times your bill could be higher.

#### How does our rate plan work?

Your energy bill has two parts:

- A service charge
- An energy charge

**The service charge**

The service charge is the same for all households — whether they run a single desk fan or a hundred air conditioners. It covers Cobb EMC expenses that aren't directly related to your energy usage. Examples are Cobb EMC's phone-support staff, and the hold music you hear while waiting for phone support. The service charge doesn't change month by month. It's only about 16% of a typical family's total monthly energy bill ($24 out of $146/mo).

**The energy charge**

Unlike the service charge, the energy charge is based on actual usage. What's the energy unit that Cobb EMC uses? Like other U.S. utilities, they charge per kilowatt-hour, abbreviated as kWh. Let's use the classic light bulb example to understand kilowatt-hours:

100 light bulbs x 10 watts per light bulb = 1,000 watts. A "kilo" is a thousand, so 1,000 watts = 1 kilowatt.

…If the light bulbs are left on for 1 hour, that's 1 kilowatt x 1 hour = 1 kilowatt-hour (when in doubt, just squish words together).

Let's make sure you have that. How many kilowatt-hours are used if you leave one hundred 10-watt light bulbs on for an hour? …1 kilowatt-hour. Here are the steps: 100 light bulbs x 10 watts each = 1,000 watts. Divided by 1,000 = 1 kilowatt (there are 1,000 watts in a kilowatt). Left on for 1 hour = 1 kilowatt-hour.

**Standard energy unit**

Unit name: *kilowatt-hour*

Abbreviated as: *kWh*

Now let's talk money. How much does Cobb EMC charge to keep this single kilowatt-hour (kWh) of light bulbs on for an hour? They charge 11¢ per kWh on average (for a home with typical usage). One kWh multiplied by 11¢ per kWh equals…11¢. If the 100 light bulbs were kept on 24x7 for a month (720 hours straight), Cobb EMC would charge $79.

**What's a typical Cobb EMC customer's energy bill?**

A typical family in Cobb EMC territory uses 1,349 per month on average (for perspective, they'd get to the same total by keeping 31 typical laptops on 24x7). They pay $146 per month for those 1,349 kilowatt-hours. How does your home compare?

**How do Cobb EMC rates compare to the national average?**

Cobb EMC rates are lower than the national average — the average Cobb EMC rate for a family with typical energy usage is 11¢ (including the service charge). The average national residential rate is 13¢.

#### What are rate tiers?

To complicate things (we're talking about energy bills after all), Cobb EMC doesn't just charge the same flat rate for every kWh of energy. They increase the rate when energy thresholds are reached across the month. In other words, the rate plan is *tiered*. Energy in the second tier is 51% more expensive than energy in the first tier.

Let's connect this to life with a 1 kW espresso machine (which draws 1 kW of power at any given moment). Let's say the machine is on for an hour every morning. That's 1 kW times 7 hours per week, which equals 7 kilowatt-hours (we'll pretend it's on non stop). With summer-season rates, the total cost to run it in the first week—at the cheaper tier-1 rate—is: 56¢. The cost to run it in the last week—at the more expensive tier-2 rate—is: 84¢. So Cobb EMC is charging an extra 29¢ for the same amount of energy.

Is it worth foregoing espresso in the last week to save 29¢? Never.

#### Does Cobb EMC charge a premium in the summer?

Yup, summer rates are 24% higher than winter rates for a typical family. Between this and higher summer usage, the average summer bill is 58% higher than the average winter bill ($179 vs $114 per month). Cobb EMC's summer-rate season goes from May 1 to October 31.

#### Would we have a lower bill on a different Cobb EMC rate plan?

Many utilities now offer an optional "time of use" rate plan. Time of use gives you more control of your energy bill. Unfortunately, Cobb EMC doesn't offer this newer type of rate plan (yet).

**Newer type of rate plan**

Typically referred to as: *Time of Use*

Abbreviated as: *TOU*

The good news is that you don't need a different rate plan to cut your bill. The next article in this series will walk you through other bill-cutting opportunities.

#### How do I work out if I am on the cheapest Cobb EMC rate plan for my usage pattern?

To do an exact comparison on how much you would save from switching plans requires collecting your detailed usage data for the last 12 months. This is known as **Interval Data** and sometimes also called **Green Button Data**.
