Smarter Energy

Overview

EKZ produces and delivers approximately 10 percent of all electricity consumed in Switzerland, making it one of the leading Swiss utility providers. Approximately one million people depend on the company’s reliable and environmentally conscious delivery of electricity and the broad spectrum of other services it offers. EKZ supports a range of measures to enhance energy efficiency and promote the use of renewable energy sources

Business need:
Electric cars promise to significantly reduce dependency on fossil fuels. Preparing the electric grid to handle significant growth in the electric car market presented EKZ, the power provider for the canton of Zürich, with the challenge of balancing energy supply and demand while satisfying customer lifestyle preferences. For renewable energy sources to play a preferred role in vehicle recharging without overtaxing supply and causing power failures, the utility is testing a method for adapting vehicle charging speed to natural fluctuations in the rate of green energy production.

Solution:
Using predictive analytics, EKZ modeled the impact of a major increase in electric car use and developed a pilot project that allows customers to charge electric vehicles and monitor their energy consumption using mobile devices. A recording unit in each vehicle monitors battery level and location. The mobile phone-link into the electric car allows customers to switch on or off the charging process according to a schedule. Future enhancements are aimed at precisely controlling the rate of fuel flow to mitigate the effects of the natural fluctuations in the production of solar and wind power.

Benefits:
Expected to shift up to 50 percent of the charging time into low peak hours of electrical grid Reduces vehicle operating costs for drivers while improving load balance for the electric utility The smart phone-link into the electrical car allows utilities as well as e-car manufacturers to offer enhanced services to their customers

Case Study

EKZ produces and delivers approximately 10 percent of all electricity consumed in Switzerland, making it one of the leading Swiss utility providers. Approximately one million people depend on the company’s reliable and environmentally conscious delivery of electricity and the broad spectrum of other services it offers. EKZ supports a range of measures to enhance energy efficiency and promote the use of renewable energy sources.

The Opportunity
Electric cars promise to significantly reduce dependency on fossil fuels. Ideally, customers can enjoy the benefits of driving vehicles that use half as much gasoline and that also obtain their electricity from renewable sources. Preparing the electric grid to handle significant growth in the electric car market presented EKZ, the power provider for the canton of Zürich, with the challenge of balancing energy supply and demand while satisfying customer lifestyle preferences. For renewable energy sources to play a preferred role in vehicle recharging without overtaxing supply and causing power failures, the utility is testing a method for adapting vehicle charging speed to natural fluctuations in the rate of green energy production.

What Makes It Smarter
Using predictive analytics, EKZ proactively modeled the impact of a major increase in electric car use and developed a pilot project that allows customers to conveniently charge electric vehicles and monitor their energy consumption using mobile devices. A recording unit in each vehicle monitors the car’s vehicle’s battery level and location. The mobile phone-link into the electric car allows customers to switch on or off the charging process according to a schedule. Customers can even remotely instruct the utility as to when to begin recharging the plugged-in vehicle. For the utility, future enhancements are aimed at providing renewable energy to the cars, precisely controlling the rate of fuel flow so as to mitigate the effects of the natural fluctuations in the production of solar and wind power. The solution is designed to help the utility safely balance supply and demand, avoiding power outages, while electric car drivers benefit from fuel price incentives and a smaller carbon footprint.

Real Business Results
· Expected to shift up to 50 percent of the charging time into low peak hours of electrical grid
· Reduces vehicle operating costs for drivers while improving load balance for the electric utility
· The smart phone-link into the electrical car allows utilities as well as e-car manufacturers to offer enhanced services to their customers
