You’ve seen the billboards all over town. Nevada Power is touting that they are using “green” power when available. Nevada Power’s billboards say, “Number One in Geothermal Power per Capita,” and “Number One in Solar Power.” But what else is Nevada Power doing to provide its customers when clean power?
According to Nevada Power Company’s parent company, Sierra Pacific Resources, renewable energy is not something novel to the company. In 1983, Sierra Pacific signed a contract for geothermal power.
Today, Nevada Power obtains its power from 27 renewable energy sources. Some of the renewable resources Nevada Power uses include geothermal, solar, hydro and biofuel.
Along with the power company using renewable resources, the State of Nevada has also decided to be more earth friendly. According to Nevada Power Company, the state law, Renewable Portfolio Standard, mandates that a “significant” portion of energy sold to customers must come from renewable resources. State lawmakers originally set the law up in 1997 to require only 1 percent of renewable resources to be used by the year 2010. But with the increased price for oil and the increasing awareness of natural resources and global warming the state when back and rewrote the books to require companies to have 15 percent by the year 2013. Once again, lawmakers revised the law requiring that companies use 20 percent by 2015.
But Nevada Power plans on going beyond the requirements of the law. According to Adam Grant in Corporate Communications for Nevada Power,
“By 2015, a minimum of 20% of our energy must come from a combination of renewables and conservation programs. We see the RPS as a floor, not a cap, because Nevada is blessed with abundant renewable resources in the form of geothermal, solar and wind energy.”
Regardless of the upcoming changes, a significant portion of our electricity is still being created at coal-burning power generating plants. Grant explains where and how Nevada receives power:
“Nevada Power generates electricity at its own power plants in southern Nevada and imports electricity from out-of-state sources. Since 2006, Nevada Power Company has added about 1,800 megawatts of company-owned generation to its fleet. These newer, more efficient plants use less fuel and water and produce less emissions. The addition of these plants also has allowed older, less-efficient plants to be closed.
Of the electricity used by our customers — a combination of company-owned power plants and power purchased from other providers — about 70 percent comes from natural gas-fired generating units.”
SOLAR POWER
In Nevada, one of our abundant resources is the sun. As Nevada Power Company’s billboard boasts, Nevada is number one in solar power usage. With cooperation from Nevada Solar One they operate the third largest solar power plant in the world, according to the Environmental News Service. When the facility opened, it was the largest solar plant built in 14 years.
The facility has a large plant that is built of basically mirrors that are similar to the ones that are in bathrooms. The mirrors take the sunlight and capture the heat into a main pipe. Inside the pipe there is specialized oil that the mirrors and the sun’s natural rays and heat help to warm to a temperature of 735 degrees. That specialized oil is then converted to steam. This steam turns a turbine and makes electricity. The plant creates, on average, 66 megawatts during the hours of 8am to 7pm.
But one of the downfalls of this type of energy production is something nobody can control, as Bob Cable from Nevada Solar One notes,
“If you see the sun, we can make power, when it’s hazy out, we can still make power…if the sun is gone, we’re no longer able to make power.”
At its current operating procedure, the plant captures enough power to power 14,000 Nevada Power customers. There are plans to increase the size of the plant so that it can add enough power for 200,000 homes.
GEOTHERMAL POWER
Another resource that Nevada has a surplus of is geothermal power. And, Nevada is second in geothermal power. Nevada Power, along with its parent company, takes advantage of geothermal power.
This type of energy production uses the heat from the earth to create power. Advantages to this type of energy are that the heat occurs naturally beneath the earth’s surface. Furthermore, heat taken from the earth can be used to put back into the ground to be used again. Thus, not adding anymore heat to the earth than is already available. This method is better than solar in the fact that these power plants can operate 24 hours a day. Sierra Pacific Resources receives power from 16 geothermal power plants around and within our state.
WIND POWER
In Southern Nevada, we all know that wind in our area can certainly ruin our outdoor plans. But it does help us when we move our events inside.
Wind power has been used for multiple purposes for years. You’ve seen the power of wind with the iconic Dutch windmills. Wind power can be used to grind grain, pump water and generate power.
Wind farms are generally large and have several wind generators. Creating power through wind is possible by using a combination of the power of the wind and drag created by the blades help to spin a generator at the top of the tower creating electricity.
Regardless of the method Sierra Pacific Resources and it’s subsidiaries, Nevada Power and Sierra Pacific Power, has a three-part strategy to help to change and improve the quality of electricity in the state. This strategy includes, increasing energy efficiency and conservation programs, expanding renewable energy initiatives and investments, and building new generating plants. The building of new power plants would be able to close down older, less efficient plants.
Nevada Power’s Adam Grant notes the importance of all three steps,
“All three of these are integral to our goal of providing clean, safe, reliable electricity to our customers at reasonable and predictable prices. They work in tandem in that none individually can achieve this goal.”
