Two utilities on two continents are demonstrating the value of the latest technologies for helping residential customers reduce energy consumption and lower their costs. This is important because often the benefits of smart grid technology have gone unnoticed or under-reported, while stories highlighting the negative aspects of smart grid deployments gain attention.
In the United Kingdom, British Gas says that 9 out of 10 customers report that smart meters have helped them better manage their energy consumption, according to a survey. Results of the survey also show that 54% of respondents with a smart meter are saving money, in some cases up to £75 ($125) per year. Also, data from smart meters has motivated 40% of customers to take some type of energy efficiency steps, such as adding insulation. British Gas has deployed smart meters to about 1 million of its customers so far. The mandated widespread deployment of smart meters is set to begin in the fall of 2015.
Here in the United States, Nevada’s NV Energy says customers enrolled in its mPowered program reduced air conditioning use by 12% and whole-house electric consumption by about 6% per year. Program participants receive an EcoFactor smart thermostat that connects the home’s AC system to a cloud-based efficiency and demand response (DR) service. Participating households reduced their load by 3 kW to 3.5 kW in the first hour of DR events last year. Customers can override a bump in temperature settings during a DR event if they want to not take part, keeping the home cooled at a level they prefer. However, the rate of overrides has held steady at about 11% in the first hour and 7% in the second hour since the utility has been tracking this metric since 2008.
These examples represent the latest evidence of smart grid technologies making a difference to customers after years of utility deployments and somewhat murky results. Pilot programs and eager vendor hype have indicated savings of up to 20% on a given customer’s bill. These two examples are noteworthy for being more realistic. They’ve been normalized over time, and over a wider customer base – plus they’re similar to results from OGE and BGE. What’s missing are similar normalized results from dozens of utilities that are using smart grid technologies to create greater efficiencies and provide ways for customers to control costs. Those results will eventually come, but until then many customers will remain skeptical.
