Summer Heat Pushes Power Demand To New Heights

It’s been a cooler than average summer up here in New England, but high temps elsewhere have pushed electric power consumption to record-setting levels. At the end of July, an Arizona heat wave sent electricity demand to a new record high. And on Tuesday, Orlando Utilities Commission set a new record for peak power demand, edging out the previous record set in 2007.

Although both utilities were able to manage the increased demand without a hitch, this is one record—like the record for biggest box office bomb—that no one wants to hold. (That dubious distinction is currently held by 47 Ronin, with a loss of ~$150 million. Ouch!)

So why isn’t a new peak great news? Just like a Hollywood flop, it can be costly. When power consumption rises to record high levels, utilities need to allocate new resources to meet the demand. Usually, that means increased expenses for consumers in the form of building new power plants or increasing new power purchases.

Fortunately, utilities are getting smarter about the way they manage demand for electricity. Through so-called “demand response” programs, they’re giving consumers incentives to use a little less power, which helps keep costs down. Sometimes information itself is enough of an incentive. For example, Orlando Utilities Commission is recommending that homeowners set their thermostat at 78 degrees or higher, about the same temperature of a typical Florida summer morning. By putting out these alerts, utilities are keeping customers comfortable—and avoiding blackouts.

With proper information and planning, utilities have shown they can manage peak demand without breaking a sweat. Or, as Ted Geisler, Arizona Public Service director of power operations, described it during the July heat wave, “We’ve been planning all year for a day just like today.”

The 10 Most Expensive States To Buy Electricity In America

If you live in Hawaii, we’ll bet that you don’t spend your days filled with regret about making your home in paradise. But if you saw the average homeowner’s electricity bill on the Big Island, you might think twice.

Hawaiian residents pay $0.37 per kilowatt-hour (kWh) of electricity, more than three times the U.S. national average of about $0.12/kWh, according to data from the U.S. Energy Information Administration.

The Hawaiian Electric Company has made some amazing strides toward renewable energy generation, but it still produces the majority of its electricity from oil, which has to be shipped in continuously throughout the year. Hence the high prices.

Even on the mainland, electricity can get pricey. Here are the 10 states with the most expensive electricity in America:

Interestingly enough, a low cost per kilowatt-hour doesn’t necessarily translate into a lower bill. In fact, despite paying only $0.10/kWh, Tennessee has some of the U.S.’s higher average bills at $123 per month. Our home state of Massachusetts, on the other hand, has higher than average prices at almost $0.15/kWh, and yet we have have below-average bills at $93.50 per month:

That indicates that the way we use energy matters. And that’s why we’re passionate about helping people make their homes more efficient. Being comfortable shouldn’t come at an unbearable cost.

Zoning 101: What Is Zoning And Why Does It Matter?

Modern Kitchen Earlier this year, we wrote a post about why a single-zone heating, ventilation, and air conditioning (HVAC) system will never keep your home comfortable. These systems don’t have the dynamic monitoring and control of ecovent, so they’re bound to over-heat and over-cool parts of your home.

But when talking to our customers, we realized most people don’t even think about whether their homes have “zones” or not. They usually just know how many thermostats they have and whether or not their homes are comfortable.

So what is zoning and why does it matter?

Zoning is the practice of separating your home into different areas and heating and cooling those areas individually, rather than trying to condition the whole house at the same time. The best analogy we know comes from lighting. Think about it: You’d never build a home with only one light switch. Instead, you’ve got one in every room and you can set the level of lighting you want individually. But most homes have only one thermostat, which means that you’re probably heating and cooling space you don’t use.

Zoning offers a few important benefits:

Increased Comfort

When you separate your home into different zones, you can finally be comfortable. Think about the temperature difference between your first floor and your second floor. Zoning can alleviate that problem by setting different temperature targets for each level. Zoned systems can do the same thing for different areas on the same floor. Say you only need to cool one area of your house at a certain time of day—for example, when the sun shines on that side of the house. A zoned HVAC system helps you differentiate between those areas and dial in the right temperature.

If you install ecovent for your zoning system, you get an extra level of comfort control. Our system doesn’t care if your home has two zones or 15. You can set the right temperature at the room level, not just floor-by-floor.

Increased Control

In that sense, zoning is all about control. In most zoned systems, you get the benefit of additional thermostats, which each serve as a different point of control. But what if you could control your entire home from a mobile phone or tablet? With ecovent’s mobile app, you can. Even better, the system adjusts automatically to keep you comfortable, so you can worry less and enjoy more.

Saving Energy

Possibly the biggest benefit of a zoned HVAC system is the opportunity to save energy. A well-designed zoning system can save you hundreds of dollars in energy costs each year, and it reduces wear-and-tear on your system by reducing run-times for your furnace or A/C unit. Your home runs more efficiently when you only heat and cool the rooms that need it.

But Is Zoning Worth It?

Most zoning systems require a complicated installation that can take days to complete. And hiring a contractor to tear into your walls to install the necessary ducting and dampers can be expensive. And if anything else in your home changes, it can quickly get out of whack.

ecovent does zoning differently. We’ve designed wireless system that anyone can install in a matter of hours. And it makes every room of your home its own zone. To us, that’s the only kind of zoning that’s truly worth it—because it’s easy, it’s smart, and you can control your comfort from the palm of your hand.
