Smart Planning for a Successful Smart Grid Roll-Out

John Finnigan PhotoBen Franklin famously said, “If you fail to plan, you’re planning to fail.”  This saying certainly holds true for smart grid deployment plans, which can cost utilities several hundred million dollars.  Given these high stakes, good planning is essential.

Many utilities have installed smart grids.  Currently, 25% of U.S. electricity customers have smart meters, a key component of the smart grid.  Some early deployments were rocky, but utilities have learned their lessons.  Utilities have incorporated these lessons learned in the planning process for more recent smart grid deployments.  A well-thought-out smart grid deployment plan should address the following topics: Read More »

Fueling Cities with West Texas Wind as CREZ Comes Online

Marita MirzatunyAs we approach the end of 2013, Texas’ power grid is soon to embark on a new clean energy path.  While most people don’t get too excited about electrical transmission and distribution lines, the much awaited Competitive Renewable Energy Zone (CREZ) transmission project– set to come online in a few weeks and roll out through 2014 – could be the exception.

Approved by the Public Utility Commission of Texas (PUCT) in 2008, CREZ is a 3,600 mile transmission line that will connect remote West Texas wind energy to the eastern cities that need its power – 18,500 megawatts of power to be exact.  This is enough power to energize 3.7 million to 7.4 million homes and increase available wind power supply by a whopping 50 percent.

Much like some other wind-rich regions in the country, wind in the West and Panhandle regions of Texas was partially unused, or curtailed, because local communities could not use all of the available supply  and the state’s current, outmoded electric grid could not efficiently deliver the abundant energy to high-demand eastern cities.  This “congestion” bottleneck forced wind farms to lower prices and at times pay the utilities to take their electricity.

The U.S. Power Grid’s Cyber War Games

In the 1983 thriller WarGames, Matthew Broderick plays a teen-age computer geek who unknowingly signs onto a Pentagon computer while hacking into a toy company’s new computer game. Thinking that he’s simply playing a game called Global Thermonuclear Warfare, Broderick launches the game and nearly starts a nuclear war.  The North American Electric Reliability Council (NERC) will hold its own war game next month with a simulated attack on the U.S. power grid.

The drill, called GridEx II, will take place on November 13-14 of this year. The participants will include 65 utilities and eight regional transmission organizations, representing most of the nation’s electricity customers.  The drill will test how well the electric utility industry and the grid itself respond to physical and cyber attacks.

A NERC Critical Infrastructure Protection Committee (CIPC) working group will begin the drill by sending participants a series of simulated physical and cyber attacks, climaxing in a national security emergency.  Participants will then respond and interact with each other, just as they would in a real emergency.  The simulation will last 36 hours, and the CIPC working group will evaluate the participants’ responses and provide feedback on how their actions impact the ongoing scenario.  After the drill, the working group will analyze the results and prepare a report on lessons learned.

Unique Partnership Creates New Energy Efficiency Loan Model For Rural Homeowners In North Carolina

Duke Energy is the largest utility in the United States, so of course it gets a lot of attention in its home state of North Carolina.  Yet millions of residents in rural parts of the state rely on electric cooperatives, not Duke Energy, to keep the lights on.  In fact, rural cooperatives serve all or part of the customers in 93 of 100 counties in North Carolina.

This is important because rural areas have just as much, if not more, need to increase energy efficiency.  Case in point: a seven-county area in eastern North Carolina served by Roanoke Electric Cooperative.  The cooperative has made great strides in promoting energy efficiency, yet there are still customers with utility bills that are higher than their mortgage payments some months.  Close to half of Roanoke Electric’s customers live in manufactured homes, which typically have less energy-saving insulation than standard homes.  And, in an economically-distressed region, few homeowners have extra money to pay for energy efficiency improvements, like caulking around windows or adding insulation.

Now, thanks to a new program offered by Roanoke Electric Cooperative, homeowners can secure low-cost loans from a private lender to make home improvements that will reduce energy use and save money.   The loan is paid back on the monthly utility bill, reducing paperwork for homeowners and making repayment easier.  In this program, the energy efficiency home loan is made by Generations Community Credit Union, a lending institution focused on assisting underserved rural communities in North Carolina.  Homeowners can borrow up to $4,000 for improvements, with interest rates as low as 3.5%.

More Companies Turning to Distributed Generation – What Does it Mean for Utilities?

Last month, the Wall Street Journal reported on an initiative at an increasing number of companies nationwide: on-site, or distributed, power generation. There are many reasons for this growing trend in corporate sustainability, along with many ramifications for the prevailing utility model in the United States – all of which highlight the importance of employing market-based solutions to create a cleaner, smarter, more resilient electric system.

Why Do Companies Unplug?

For companies such as Walmart, increasing the use of distributed, renewable generation is a vital part of larger sustainability goals, including increased use of clean energy and a call for safer ingredients used in the products the company sells. To be sure, however, even the most altruistic companies would be hard pressed to shift off the power grid without sound economic reasons.

A confluence of market factors, including tax incentives that spur attractive returns on investment, advances in solar and wind technologies and policies that encourage greater use of and investments in clean energy (like net metering and time-of-use pricing), has created an economic environment that makes distributed generation not just a viable option, but often a very attractive one. Further, off-grid power can be an effective way for companies to hedge against outages due to storms or unforeseeable catastrophes, a key idea included in the Hurricane Sandy Rebuilding Strategy.

The Electric Utility Of The Future

Progressive Power Providers Show a Path Forward

Traditionally, electric utilities have been in the business of providing reliable power to their customers.  Prices for each class of customer are fixed by state regulators and a customer’s choice is pretty much limited to whether they want to turn on the switch or not.  Much of the EDF Smart Power initiative is focused on helping to create new utility business models that change this paradigm by increasing customer choice, providing market feedback on these choices and incentivizing the use of cleaner sources of power.

Several electric utilities are getting ahead of the curve by embracing these changes.  While both own large fossil fuel assets, NRG Energy and NextEra Energy have also been developing utility-scale and distributed renewable generation projects across the country.  NRG Energy develops solar and other renewable projects for government, commercial and other institutional customers, and NextEra Energy, the largest generator of wind and solar power in North America, develops and finances large commercial and small utility solar projects through its subsidiary Smart Energy Capital. Cumulatively, they have provided more than 110 megawatts of distributed solar generation capacity to schools, government and commercial facilities, among others.

Over the past week, two other energy providers, Direct Energy and Viridian, have announced deals with SolarCity to offer no-upfront cost solar installations to their current and prospective customers.  In many cases, these solar installations will provide clean energy at a lower cost than the customer currently pays for dirtier, fossil fuel power.  Direct Energy even took it a step further by agreeing to provide part of the financing for their customers.  Since there are few investors that currently finance solar projects, Direct Energy can expect to earn a very attractive return on their investment.  While solar financing has been around for several years, Direct Energy and Viridian can now offer customer solutions that bundle solar installations with other energy services.
