Understanding the Energy Market

What you need to know as a consumer

Ever wonder why your utility bill changes so much? Just who decides how much a kilowatt hour is worth? The energy market can be vast and confusing, but there's a few basic things to know that can help you understand just what makes the energy market so different from any other market.

One with the Grid

Every source of energy – whether that be from natural gas, oil, coal, wind, or solar – ends back up in the grid.

Unless you live off the grid completely, your house, apartment, or business office is using energy that is sent out along the grid network of poles, wires, cables, and pipes. Meters attached to each unit capture how much energy is being consumed every month. Employees from the utility company read this information and calculate the total kilowatt hours for the billing period.

As the customer, you get charged for those kilowatt hours (denoted as kWh) depending on the current rate. For instance, if the utility or energy provider is charging 20 cents per kilowatt hour and your total kilowatt hours (how many kilowatts you consumed per hour) for the monthly billing period is 900, then your monthly bill will be $180.00 (excluding service and maintenance fees that the utility provider charges).

Unfortunately, it's often not as straightforward as that. Like any market, rates will change, and often multiple times with one billing cycle. This is why your monthly electricity or gas bill is always different each month, even during times of the year where demand is always high. As a whole, the energy market is one of the most volatile ones out there.

Why Do Prices Fluctuate so Much?

There are a number of things that can affect the kWh rates.

Like with any product, demand and supply is the underlying driver of prices. However, unlike a normal market, the energy market's supply is always transient. Because there isn't a consistently reliable way to store the energy that is being generated, it has to be used right away. It goes directly from the source to the customers and then is gone. Used up. This applies more specifically to electricity supply than things like gas, which can be stored better than electricity can.

Think about other resources like food. When harvest time comes, farms can store the excess grain and produce into silos or cold storage to be used when the supply starts to run low in the late winter. This means that prices will remain relatively stable. Unfortunately, the energy market has no equivalent for silos or cold storage. There are batteries, but they can only store so much, and their capacity to store high volumes of power degrades rapidly after each discharge.

So, when there is a higher demand for a supply that can't be stored, energy has to be generated at a much faster rate to make up the difference. They can't dip back into reserves to help supplement the load. The result? A higher electricity bill in September after a month of putting the AC on full blast because of the long hot days.

Other Factors that Affect Rates

A lack of consistent storage isn’t the only thing that affects market rates.

Some of the others include:

  • Where you live
    There is no federally regulated energy market across all states, which is why rates change depending on where you live. Hawaii, for instance, gets charged roughly 37 cents per kilowatt hour while Washington state enjoys a mere 9 cents per kilowatt hour. Sadly, there isn’t much you can do about that besides picking up and moving from your island paradise to the daily rain of Washington.

  • Residential vs Industrial
    The type of customer using the energy also affects the rates. For instance, industrial customers will be charged less per kilowatt hours than residential customers because they will be using much more energy. It works similar to a buy-in-bulk kind of program.

  • Who your utility company is
    Remember, your total utility bill each period isn’t just charges for the energy that you used. It also includes delivery fees and maintenance fees that the utility company servicing your area charges in order to maintain the infrastructure so that the power can reach your home or business. These fees will vary depending on which utility company, which are also affected by the weather conditions and other factors for your region.

What solutions are available to customers?

The good news is that the main problem driving a volatile market can eventually be solved as technology gets better.

Already, grants given to places like MIT are being put to use in order to develop better battery technology1 that can be used in industrial-sized storage needs. The bad news is, the customer that still needs to use energy and pay a monthly bill probably won’t be seeing the payoffs of those improving technologies for quite some time.

There are a few other ways to help ease the strain of a volatile market on the consumer, however:

  • Developing smaller, smarter microgrids
    The idea here is that the smaller the grid, the easier to manage, and the less it will cost to maintain. Cities like Pittsburgh are trying to think outside the box by planning a series of microgrids2 that will incorporate smart transportation links as well, such as electric buses. The goal is to improve traffic and air quality while cutting down on energy costs for city transportation.

  • Fixed rate and subscription-based energy plans
    In deregulated markets, customers can choose their energy supplier. Many of these companies are starting to move into fixed rate plans, meaning that no matter the month or season, your rate per kWh will never change. Additionally, some companies are considering subscription services, which work in a similar way to fixed rate plans. The main difference is the bill each month. That will stay the same on a subscription plan regardless of the time of year or how much energy was used that month.

Though the energy market is a volatile one, steps are being made to ease the strain on people who have no choice but to use energy in their daily lives. Since we’re all connected to one grid, it’s all in our best interests to try to make that part of living a whole lot easier.
