Certified Residential &
Commercial Electricians


If you are like most people in the Tri-Cities area, you spend a great deal of time in your home. Technological advances in recent years mean you don’t have to leave your house to see the latest movies, shop or otherwise entertain yourself. How you choose to live could affect your electrical needs. As you add more technology to your home, it could overload your current systems or cause the need for other repairs.

According to the Alternative Fuel Data Center (AFDC), sales of electric vehicles grew from 159,616 cars in 2016 to 326,644 in 2019 (latest data available). In fact, in 2011, it is estimated that less than 18,000 electric vehicles were sold in total. As the popularity of electric vehicles has increased, demand for electric vehicle charging stations has soared as a direct result. Altogether, industry revenue has increased at an annualized rate of 13.9% to $1.8 billion over the five years to 2021, including anticipated growth of 14.0% in 2021 alone.
