Electric Cars Facilitate Smart Grid 2.0

The electric car will facilitate the smart grid and a renewable energy charging infrastructure. The electric car will help make the smart grid relevant to consumers. Right now most cars use inefficient engines fueled with gasoline or diesel. In the coming decades, many cars will use electricity. With a smart grid, renewable energy will do much of the charging.

New electric cars from Nissan, Toyota, GM, Ford and others will use a charging standard J1772. The new charging units at home and work will include a smart meter chip. When a driver plugs-in, charging will follow preferences pre-established by the car owner. Many will prefer to save money and charge at night when rates are cheaper.

States with the earliest adopters of electric cars are also states where utilities face big renewable portfolio standards (RPS). The lowest cost renewable per megawatt is wind, but much of the wind turbine power is delivered at night when winds are most constant. With a smart grid and price incentives, electric cars will be charged off-peak using renewables.

The promise of smart grid electric vehicle charging was discussed at the GreenBeat 2009 conference last week by technology leaders such as Google and Cisco, and utility leaders such as Duke Energy and Southern California Edison. Al Gore presented smart grid and super grid findings from his comprehensive new book about climate solutions – Our Choice.

The current Smart Grid 1.0 is frankly boring. Smart Grid 2.0 promises to make our life better with less use of damaging coal power emissions.

With Smart Grid 1.0, new electric meters are being installed. Utilities save because they no longer need to send people out to read meters. Services can start and stop without rolling trucks to make manual connects and disconnects. Utilities are saving while the consumers pay for the new meters with rate hikes.

Electric utility industry has shifted from years of falling costs to rising costs. Utilities need to shift energy use and vehicle charging off-peak to avoid unnecessary investments in expensive peaking power plants. A smart grid is needed to fully utilize renewable energy and moderate fossil fuel emissions.

Smart Grid 2.0 could help some people over $1,000 per year by automating their preferences in heating, cooling, running smart appliances, and even doing jobs like running the dishwasher when excess renewable energy is available. Energy efficiency and demand management is already saving some enterprises millions per year. Most state public utility commissions (PUC) are afraid of implementing consumer time-of-use (TOU) pricing to give people the incentive to use energy when it is plentiful not scarce. The latest class action lawsuit hardly encourages PUCs to act more boldly.

Public utility commissions are more willing to allow pricing incentives for vehicle charging. Electric cars will help move us to Smart Grid 2.0. Through web browsers, smartphones, and vehicle displays, drivers will select smart charging preferences and get feedback on how to use less electricity and save money. Early electric cars will cost more than their gasoline counterparts, but their electric charging will cost a fraction of the cost of gasoline fill-ups.

Currently, there are only 40,000 electric cars running in the United States. As exciting new offerings are being tested and sold, 1.5 million electric cars are expected in the U.S. by 2015 presented Sharon Allan, the Senior Executive, North American Smart Grid Practice, for Accenture.

Charging these electric cars will help transform the promise of a smart grid into a convenient cost-saving reality.
