EVs, EV Charging & Storage

Digest (March 2015)

Pacific Gas and Electric and automaker BMW are teaming up to test the ability of EV batteries to provide services to the electric grid; MidAmerican Energy completed work on four of five wind farms across Iowa that make up its Wind VIII project; GE received an order from the Tennessee Valley Authority to supply two high-efficiency 7HA.02 gas turbine generators for the new combined-cycle Allen plant; Appalachian Power plans to rebuild the existing South Bluefield-Wythe 69-kV transmission line; Bechtel partnered with Westinghouse Electric to provide decontamination and decommissioning services for nuclear power plants throughout the U.S.; SunEdison and Omnigrid Micropower signed a framework agreement to develop 5,000 rural projects, representing 250 MW of electricity, throughout India; The Tennessee Valley Authority and DuPont partnered to generate power and steam at TVA's Johnsonville site in Tennessee; and others.

Electric Vehicle Charging: Tariffs and Tradeoffs

We examine various types of charging strategies and infrastructure available today and report on the experience gained from rate structures for electric vehicle charging now being offered at four different utilities. These findings lead us to provide recommendations to achieve more productive use of the electric grid.

Behind the Meter: What's In Store

Key steps for companies considering on-site energy storage.

The energy storage market is gaining momentum. Drivers: Growing penetration of renewable energy in the resource mix; Increasing focus on climate change and resource scarcity; Growing prevalence of demand charges for commercial and industrial energy users; and various other regulatory changes.

Customer First

Is the current regulatory compact in anyone’s best interests?

Serving customers’ needs should be a top priority for power companies, irrespective of the regulatory construct and business model. Transformation doesn’t change this basic fact, but how do we break the model without breaking the system?

Results-Based Regulation

A more dynamic approach to grid modernization.

The utility’s role is changing, and regulation must change along with it – to spur innovation and respond to evolving customer needs. Modernizing the industry will require a dynamic approach.

Valuing Distributed Storage

A complex business case calls for sophisticated modeling.

Flexible energy storage systems are costly, but a unique set of benefits makes them attractive. Realistic valuation supports a storage business case.

Islands in the Storm

Microgrids begin to make economic sense.

With microgrids in place, doomsday preppers wouldn't need to worry so much about a zombie plague.

Smart Grid at a Crossroads

Refining the business case for advanced  distribution investments.

As utilities plan their capital budgets for the next few years, investments in advanced distribution systems face an uncertain future. Customers question the value—and propriety—of some programs, while long-term strategic goals depend on seamless integration. What will be the path forward for smart grid technology?

CEO Forum: Facing the Future

Three CEOs, three business models, one shared outlook.

Cheap gas, regulatory uncertainties, and a technology revolution are re-making the U.S. utility industry. Top executives at three very different companies—CMS, NRG, and the Midwest ISO—share their outlook on the industry’s transformative changes.

Edison Under the Hood

Can utilities put EV batteries in the rate base?

Thomas Edison once hoped to make a fortune in the auto business—selling electric cars. Of course it never happened; he and Henry Ford tried and failed to bring a low-cost electric car to market. They scuttled the project after investing $1.5 million toward the effort—more than $32 million in today’s dollars. Edison’s nickel-iron batteries just couldn't match the performance of Ford’s petrol-powered bang-bang.
