EDF Energy Innovation Series Feature #8: Clean Energy Options From NRG

By Jim Marston / Published: July 26, 2012

Throughout 2012, EDF’s Energy Innovation Series will highlight more than 20 innovations across a broad range of energy categories, including smart grid and renewable energy technologies, energy efficiency financing, and progressive utilities, to name a few. This series will demonstrate that cost-effective, clean energy solutions are available now and imperative to lowering our dependence on fossil fuels.

Depending on whom you ask, utilities and independent power generators like NRG Energy (NRG) could be the savior or the victim of the country’s future energy system. The smart grid — an upgraded electrical system that connects generators, distribution systems, homes, offices and the millions of devices that use energy — could be real trouble for traditional utilities. If they don’t evolve, well, we know what happened to the dinosaurs.

And New Jersey-based NRG is making some impressive moves in an industry not known for rapid change.

Utilities have a lot to lose if they stand still and watch this wave of innovation pass them by. But they also have a tremendous amount to contribute, and leveraging their expertise and capital could accelerate the innovation cycle and establish the generators and transmission and distribution companies as a critical piece of the electric grid of the future.

In 2010, NRG acquired Green Mountain Energy Company (GME), a Texas-based business that has been providing clean energy to consumers and businesses since 1997, making it the longest serving retailer of its kind. It is still the only retail energy provider (REP) in Texas solely focused on cleaner energy. In many ways, GME can be considered a “founding father” for the renewable energy sector, owning many “firsts” in the REP market:

GME was Texas’ first REP to offer pollution-free products when electricity competition began in 2002.
GME developed Texas’ first pollution-free electricity product specifically for electric vehicle owners.
GME customer demand helped develop over 50 wind and solar renewable facilities in U.S., including the first utility-scale wind farm east of the Mississippi – a wind farm built in Pennsylvania in 1999.
GME created a program, the Green Mountain Energy Sun Club, that to date has built solar arrays to power 35 non-profit organizations including schools, museums, zoos and Habitat for Humanity homes. Each installation includes an educational component explaining the benefits of solar energy to the non-profits’ stakeholders.

GME also provides clean energy to some iconic American brands, further proving the viability of the renewable market while also leveraging visibility to encourage others to go green. Examples include the Super Bowl XLVI, Empire State Building (powered by 100 % wind energy) and Atlantic Cup (first carbon-neutral sailing race in the U.S.).

“With significant growth, customer commitment and a passion for clean energy, Green Mountain continues to accelerate a clean energy future,” said Helen Brauner, senior vice president of Marketing & Strategic Planning, Green Mountain. “Thanks to our customers who share in our mission to change the way power is made through customer choice, we’re celebrating 15 years of dedication to renewable energy this year.”

NRG is also the largest solar power developer in the country and is a leading owner and operator of photovoltaic (PV) systems at residential and commercial locations. Through the NRG Solar subsidiary, the Company is developing two complementary technologies — photovoltaics and solar thermal — at two of the world’s largest solar projects of each type: the 290 megawatt PV Agua Caliente Project in Arizona and the 392 megawatt Ivanpah Solar Electric Generating System in California. Upon completion in 2014, Agua Caliente will be the largest solar PV project in the world and will generate enough electricity to power more than 225,000 homes.

Additionally, the Company is building the nation’s first privately-funded, comprehensive electric vehicle (EV) charging infrastructure. The eVgo^SM system integrates home EV charging docks with a network of fast-charging stations that can charge a vehicle with a 100 mile range in a half hour or less. eVgo gives EV owners range confidence as they leave home every day with a full charge and know they can charge their vehicles quickly and conveniently if they need additional range. Additionally, the eVgo set-rate charging plans reduce the upfront cost of EV ownership while giving price certainty to EV drivers for the cost of fueling their vehicles.

“Electric vehicles are beginning to make a meaningful entry into the transportation market,” said Arun Banskota, President of NRG EV Services, the operator of the eVgo network. “As the EV market grows, we need to ensure that customers have the needed charging infrastructure. Residential and workplace charging, backed up by public charging stations, are critical to encouraging greater EV adoption, and we want to provide this key piece of the new energy infrastructure to ensure car buyers can buy an EV with confidence.”

NRG’s clean energy investments cover a wide range of initiatives; it owns 450 megawatts of Texas wind power, supplying clean windpower to thousands of homes. Through its retail subsidiaries and NRG SunLease, the Company leases rooftop solar panels to commercial and residential customers to reduce their electricity costs. NRG has a partnership with the University of Delaware to develop eV2g, or electric vehicle to grid technology, that might someday pay EV drivers for plugging in their cars. NRG is also developing carbon capture technology at its Petra Nova subsidiary that could reduce carbon emissions from older coal plants in the future.

EDF Energy Innovation Series Feature #7: Cloud Platform From Tendril

By Jim Marston / Published: June 28, 2012

For more information on this featured innovation, please view this video on Tendril’s cloud platform Tendril Connect.

Solar panels. Electric vehicles. Wifi thermostats. Home security and energy management systems. More than ever, the devices we use every day have the potential to talk to each other and work together. It’s what some people are calling the “Internet of things” or the “Energy Internet,” and it has the potential to put an amazing amount of control in consumers’ hands.

Boulder, Colorado-based Tendril is linking all those devices — and the data they generate — together. Tendril’s staff merges decades of expertise in the energy industry, software development and behavioral science with one goal: to deliver the most engaging consumer applications, so that both utilities and the manufacturers of smart goods and products can connect more closely with their consumers. Tendril hopes its software platform—Tendril Connect—will be the platform for the Energy Internet.

Just as software developers big and small are able to build apps for Windows, OSX, Android and iOS, they are also able to build energy apps for devices that may tell you the best electricity rate plan based on your usage and your utility’s offerings, or point you to changes you can make to shrink your carbon footprint.

In January 2012, Tendril opened its Application Programming Interfaces (APIs) making it possible for third party developers to leverage Tendril’s platform to create apps. More than 400 developers have registered with the company’s application developer program and more than 20 third party apps have been created—many at “hackathons”.

For example, in May at The Next Web “Hack Battle” coding marathon, in Amsterdam, a 15-year old hacker used Tendril’s APIs to build a prototype app that used geolocation data (GPS) to retrieve meter and customer information in order to control his home’s energy usage.

“It blew us away,” O’Neill said. “We gave this kid the tools, and he made a prototype in one weekend. Just imagine what teams of developers could do with a few months of work.”

Tendril Connect is an open standards-based cloud platform that connects utilities, homes, applications and devices to realize the opportunities unlocked by new, smarter grids.

As more and more energy data becomes available and more and more developers use this data to create compelling apps, consumers will have increased insights, choice and control over energy management.

One example is GreenButtonConnect.com, where consumers can upload their Green Button data and select Green Button apps from an app gallery. Green Button, supported by the Obama Administration and an impressive number of companies and organizations, is literally a green button on utility customer interface websites that customers can click to instantly download their historical energy use data in a simple, standardized electronic format.

“When it comes to energy products consumers want simplicity and ease of use,” O’Neill said. “But so do the innovators that will make those products. The amount of data being created by the energy system is exploding, but developers need a common language or platform to build on.”

All types of companies are moving into this area, from utilities and other energy-focused companies to information technology entrepreneurs who are looking at energy issues for the first time. The potential for profit is coming into focus, and developers want to get in early and create the Energy Internet’s first killer app.

ERCOT’s Three-card Monte Trick For Grid Reliability

By Jim Marston / Published: June 25, 2012

(Credit: Arnie Levin)

This commentary was originally posted on the Texas Clean Air Matters blog.

First we have enough generating capacity, but next year is the problem; now that next year is upon us it’s really the next few years that are the issue. The Electric Reliability Council of Texas (ERCOT), grid operator for most of Texas, foresees potential electricity shortages. Clearly the risk is real, but when? This year? Two years from now? Reports swirl by, some only weeks apart, showing different numbers and contradicting previous reports. Are we seeing a bureaucratic version of Three-card Monte?

During last summer’s drought, demand peaked on August 3, using more than 68,000 megawatts. ERCOT’s stated goal is to maintain a 13.75% reserve margin in generating capacity. Their latest report shows the state’s electrical grid will fail to meet the target reserve margin as soon as 2014, two years from now. A report in early May actually shows that this summer ERCOT will fail to meet that target as well, although it isn’t stated explicitly.

Meanwhile EPA is meeting with ERCOT and the nation’s other grid operators to develop an implementation timeline for the new Maximum Achievable Control Technology (MACT) air toxics rule, which should begin this fall. Utilities have three years to implement the new rules…unless the three-year timeline threatens grid reliability. Then utilities can get a fourth year…unless grid reliability is still threatened. Then utilities have a full five years to comply.

Concerns about grid reliability are very real, but they are due to power companies deciding to hold off on constructing new power plants while prices are so low. Unfortunately some state leaders and utilities have seized on these ERCOT reports, and are shifting their conclusions in an attempt to delay rules that have been in the works for years, and in some cases decades. The new EPA standards will dramatically cut mercury, heavy metals, acid gas and other emissions from power plants. The public health benefits to our state will be enormous, especially for Texas children who breathe air tainted by power plant emissions. The cost of unwarranted delay is a price Texas should not have to pay.

Energy Documentaries – Educational Or Sensational?

By Jim Marston / Published: June 19, 2012

The 24-hour news cycle has prompted a higher quantity of topics brought to viewer’s and reader’s attention. However, with sound bites and the brevity of social media, rarely are topics reported with a balanced level of quality. Film documentaries are evolving as a more sophisticated medium to explore issues in expanded formats with interviews, commentary and a wider perspective. But are some of these documentaries more fiction than fact?

An Inconvenient Truth advocated common sense about climate issues. The Academy-Award nominated Gasland sparked much controversy about exploration and production of natural gas. Its sequel, Gasland II, is scheduled to air on HBO this summer. This week, a film Truthland debuted on YouTube (not in theaters) with more splash than substance.

Of EDF’s core strategies of sound science, market-based solutions, non-partisan policy and unlikely partnerships – a most unlikely partnership was mischaracterized by the producers of Truthland. My words in an interview in the documentary are accurate, but the context in which they were presented — implying that EDF agrees with the rhetoric presented in the film — is misleading. When interviewing for this film over a year ago, I was not told that the film would be subsequently sold to Independent Petroleum Association of America (IPAA) and Energy In Depth (EID), and used a promotional tool for the natural gas industry. In hindsight, I should have demanded more limitations on my interview – but the producers were very convincing when pitching the film as a presenting a “balanced perspective” on the natural gas debate.

Rather than promoting Truthland, I suggest a more impartial documentary choice where EDF’s Senior Energy Policy Advisor Scott Anderson is interviewed as demonstration of how EDF’s efforts can decrease the adverse effects of natural gas development. The SWITCH Energy Project offers a more sound approach to reviewing the past, present and future of energy solutions for the U.S. and globally. University of Texas’ Bureau of Economic Geology’s Director Dr. Scott Tinker explores the world’s leading energy sites, from coal to solar, oil to biofuels, with interviews of international leaders of government, industry and academia experts, plus a voice in the environmental community.

Scott Anderson’s interview in the film describes the natural gas drilling method of hydraulic fracturing and the regulatory atmosphere of improving environmental aspects pertaining to water, land and air quality issues.

EDF Energy Innovation Series Feature #6: The Learning Thermostat From Nest

By Jim Marston / Published: June 14, 2012

For more information on this featured innovation, please view this video on Nest’s Learning Thermostat.

Imagine you were the leader of the team that developed the first 18 iPod models and the first three iPhone models, and you’ve decided to move on to the next big thing. What will you invent next?

Tony Fadell was the leader of those teams, and when he left Apple he set his sights on reinventing the home thermostat. That’s right, the home thermostat. And his company – Nest Labs Inc. (Nest) – has become one of the hottest startups in Silicon Valley.

Thermostats have evolved over the years, and many companies now make programmable models that can adjust temperature settings throughout the day. That’s good news: residential and commercial heating and cooling accounts for nearly 40% of all U.S. carbon emissions. So improving the efficiency of heating and cooling is a critical piece of the climate puzzle and helps to lower electricity bills.

But even today’s “modern” thermostats seem to miss the mark.

“I bet your thermostat is ugly and impossible to program,” Fadell writes on his blog. “And I bet it drives you crazy.”

Source: Nest Labs Inc.

The Nest Learning Thermostat looks like an old-fashioned circular thermostat that got a 21^st century facelift. You can certainly see the design approach that produced the iPod and iPhone. But what’s inside the Nest is more interesting: proximity sensors that know when you’re home, software that learns your heating and cooling preferences and wireless technology that allows you to monitor and adjust it from a website or a smartphone.

Nest says that few people use whatever programmable features their thermostats might have, and energy-conscious owners that adjust their thermostats manually (when they leave or arrive) make up to 1,500 adjustments a year. Nest’s Learning Thermostat automates those adjustments and makes them a lot easier.

“We threw out everything we know about regular thermostats and started from scratch,” said Nest’s director of corporate communications Kate Brinks. “And we ended up with a product that’s squarely focused on the user.”

Nest estimates that 90% of us don’t want to fiddle with the programming features of thermostats. So its device “learns” its owners preferences based on how the temperature is adjusted over a week or so, and then sets a schedule based on those preferences. Its proximity sensor can detect when the home is empty and when people arrive and build those patterns into its schedule.

For users that DO want a firmly set schedule, the “learning” features can be turned off. And for the growing number of smartphone owners, the device can be securely monitored and adjusted from anywhere. Brinks says that 99% of installed Nest thermostats are running an energy-saving schedule.

The smart grid, the Internet and wireless technology are creating a convergence of consumer electronics and energy. More and more of our daily activity involves devices and systems that can now be connected. Making that potential relevant, easy and even enjoyable for people will determine whether these products go mainstream and make a real impact on our overall energy use.

Nest says its Learning Thermostat is installed in every state in the US, has recently expanded into Canada and is now available at Lowe’s, on Apple’s online store and Amazon.com.

As you’d expect from a Silicon Valley tech start-up, Nest is mum on its plans for future products. “We’re 100% focused on making the simplest, most user-oriented thermostat,” said Brinks. But it’s hard to imagine that the company doesn’t have plans to reinvent a few other home-based products.

Energy Innovation Series Feature #5: Data Analytics From GridGlo

By Jim Marston / Published: May 31, 2012

GridGlo uses “data fusion” to analyze and predict energy consumption behavior. Find more information on this featured innovation here.

The smart grid industry is more than a foundation for solar energy and electric vehicles. It is also a treasure trove of information that requires a much more sophisticated way to capture, analyze and use the billions of bytes of information that a modernized grid and its many components will generate.

Add to that the massive amounts of weather, social, emissions and other kinds of data already being collected and you can see that a smarter grid is going offer lots of job opportunities to data geeks and software engineers.

Media and analysts predict that the smart grid information sector will be a multi-billion dollar market and companies are already jockeying for big data market leadership, from established IT giants like IBM and energy hardware companies like Landys+Gyr, to tech-driven start-ups like Florida-based GridGlo.

GridGlo works with utilities to integrate energy usage and behavioral data using its unique software platform to identify, score and predict energy consumption behavior. One of its products, Energy People Meter™ (EPM), provides a real-time digital fingerprint of energy behavior patterns and creates score that helps utilities (and consumers) save energy and money.

“Utilities have spent billions upgrading their metering infrastructure,” said GridGlo’s founder and CEO Isaias Sudit. “But those systems are now generating a lot of data and the utilities need help figuring out how to use it effectively. Our software allows them to save money on the infrastructure side, while providing new and exciting services to their customers.”

Utilities have long used data as a forensic tool to help pinpoint problems that happened in the past, such as blackouts. The real opportunity and challenge, according to Sudit, is moving from using energy data to tell us what has happened, to using it to tell us what is happening right now – and eventually, helping us predict what will happen in the future.

That kind of predictive analysis requires merging energy data with other data sets, like weather, lifestyle trends or demographics – a process GridGlo calls “data fusion.” For example, utilities could use known demographics of likely electric vehicle buyers to better plan where infrastructure improvements are needed – before the grid is overstressed. Or national or regional demographic shifts could help utilities or regulators better plan transmission construction.

“Ultimately, all of this has to show value to the customer,” Sudit said. Eventually, he thinks data fusion will be used by third party service providers and app makers, much like mobile, location and social data is used to power some of today’s most popular products.

“But our most urgent need is to show how utilities can use this information to provide value directly to customers,” he said. “If we can do that, the secondary markets will follow.”
