Fossil Fuel Industry's Tired Battle Against Clean Energy is Also a Losing One

The assault on successful renewable energy legislation continues, long after the facts have proven that state renewable policies deliver clean, affordable, and reliable energy solutions that the majority of Americans support. Apparently, the fossil fuel industry and its so-called “free market” allies didn’t get the memo.

There’s a great line in the opening scene of Ridley Scott’s 2000 blockbuster Gladiator where a soldier says to his general, as they are about to slaughter an overmatched foe, “People should know when they’re conquered.” The general replies, “Would you? Would I?”

So I can’t really blame the fossil fuel industry for fighting old battles in an effort to undo approaches that have increased investment in renewable energy in states around the country, created thousands of jobs, and continue to lower energy costs with each passing day. Read More »

UPDATE: Demand Response Helped Texas Avoid Rolling Blackouts in the Face of Polar Vortex

Good news for clean energy in Texas!

The Electric Reliability Council of Texas (ERCOT), Texas’ power grid operator, presented a report recently confirming what we already knew: demand response is a worthwhile investment that strengthens Texas' power grid.

Demand response is an innovative tool used by utilities to reward people who use less electricity during times of peak, or high, energy demand. In effect, demand response relies on people, not power plants, to meet the demand for energy. And on January 6th when the Polar Vortex hit Texas, it did just that.

Demand response kept the lights on in Texas by providing more than 600 megawatts of power to the electric grid within 45 minutes. Again on January 18th, demand response came to the power grid’s rescue, when a malfunctioning power plant failed to provide electricity despite mild temperatures and fairly low power demand. As noted before, this report highlights events that occurred during the winter of this year, at a time when Texans do not typically expect the power grid to be strained, unlike the summer. This means that a reduction in energy use – or negawatts – was able to stabilize the electric grid such that blackouts were avoided.

As shown in the report, ERCOT's Emergency Response Service is a reliability mechanism used during extreme events when the power grid is at risk of rolling blackouts. Part of the program is the procurement of demand response, which was only in the pilot phase last year, but has now been formally adopted. This program was utilized during the extreme weather events this winter and relied on the participation of hundreds of Texas businesses, schools, local governments and individuals. Read More »

Demand Response Is the Best Cure for Texas’ Ailing Grid

The Texas Public Utilities Commission (PUC) has, yet again, kicked the can down the road on securing reliable energy to power the state’s growing population. The PUC, the state agency charged with managing electricity rates, meets to securely plan for the future, yet they continue to delay planning meetings. This will benefit no one in the short or long-run. To secure reliable power and safeguard against threats of blackouts, the PUC needs to keep pace with the times and leverage technologies that require little to no water, generate negligible carbon emissions, and can respond to the call for electricity.

Last week, the PUC decided to postpone indefinitely an important meeting, originally scheduled for May, to discuss Texas’ recent blackout scares. The PUC has been in a heated debate over Texas’ electricity market structure, and in the midst of backlash from stakeholders, they have decided to push the decision onto the Legislature in 2015. This is not necessarily in the best interest of the state. Texans were asked to conserve energy several times this winter after colder temperatures forced heating units to ramp up. This request to turn down thermostats for threat of rolling blackouts came at the same time the state power grid operator assured Texans that reliability is on the upswing. But it’s time Texas faces the facts. Read More »

GigaFactory Proves that Tesla is Ahead of the Clean Energy Curve, But Does Texas Stand to Benefit?

Disruptive technologies tend to follow a certain trajectory. First, they are outliers, often ignored, and typically on the cusp of never entering the market. But, for the successful ones, a tipping point is ultimately reached, after which the technology goes viral and changes the status quo it was designed to replace. In the new energy revolution, Tesla is one such company that has surpassed the tipping point and threatens to change the way we produce, distribute, and consume electricity.

It isn't just Tesla's sleek and beautiful electric vehicles that will be key to disrupting the status quo. At a current price point of around $80,000, most people en masse won’t be able to afford a Tesla, even though the company has plans to develop more affordable models. But what makes Tesla unique, besides the strange genius of CEO Elon Musk, is the potential diversification of its offerings, highlighted recently by the company's announcement to build the GigaFactory, a $5-billion battery factory that will employ 6,500 workers.

Set to open in about three years, the new GigaFactory will be large enough to manufacture more lithium-ion batteries than the entire industry produces now, and due to its sheer scale, is expected to reduce the cost of batteries by almost one-third. Read More »

New Database from Pecan Street, WikiEnergy, Promises to Reveal Important Energy Insights

As our society moves deeper into the realms of big data, at times it can seem overwhelming that our actions can generate millions of data points. Therefore, what we do with that data becomes crucial in the new energy landscape, as big data promises to improve our lives by unlocking innovation.

By 2015, 340 million smart meters will be supplying data to utilities worldwide, reading and reporting energy from 15-minute to 1-second intervals. For a medium-sized utility, with a half-million meters, that adds up to 52 billion data point a year. Utilities are not necessarily equipped to interpret this information, and insights can be lost.

Enter the newest arm of Pecan Street, Inc: WikiEnergy.

Pecan Street Research Consortium houses the largest residential energy-use database in the world. From solar energy to electric vehicles and everything in between, they are figuring the dynamics of a smart grid, in real-time, with real residents in multiple cities across the US. Now the data that they have been collecting since 2010 can be utilized by academics and researchers from all over the world on this new website platform. Read More »

On Monday in the heart of downtown Austin, St. David’s Episcopal Church unveiled its new 146-kilowatt solar array. Covering the rooftop of an adjacent parking garage and earning the title of largest rooftop solar installation downtown.

The project’s unprecedented scale was made possible through a partnership with Meridian Solar and a new Austin Energy (AE) pilot program, testing how they can best integrate large rooftop solar with the utility’s grid. Church members had the idea to put solar panels on the parking garage ten years ago, but weren’t able to move forward until last year when low interest rates, improved technology, and government rebates all came together. Through their combined efforts, St. David’s, AE, and Meridian have taken a vital, first step towards a city powered by clean, local, rooftop power, also known as distributed generation (DG).

Secretary Moniz Deems Austin’s Pecan Street ‘Very Impressive’

Marita with Moniz

EDF's Marita Mirzatuny with Secretary Moniz at Pecan Street's Pike Powers Labratory

Earlier this month, I had the privilege of presenting a short summary of EDF’s Smart Power Initiative to Dr. Ernest Moniz, the U.S. Secretary of Energy. As a group of over 30 people piled into the Pike Powers Laboratory (including the lab’s namesake), the Secretary made his way in, beelined for some coffee, and sat down to hear all about Austin’s innovative and collaborative energy “ecosystem.”

Present was the Mayor of Austin, Lee Leffingwell, various cleantech entrepreneurs sponsored by the Austin Technology Incubator (ATI), representatives from the State Energy Conservation Office (SECO), and the Governor’s office, among others.

Everyone had the opportunity to speak to the Secretary in a roundtable format about the work their particular company or group is doing to solve energy problems, and as EDF’s representative, I reported on our Smart Power work in Texas. Read More »

How Electric Vehicles Are Strengthening the Texas Power Grid and Improving Air Quality

San Antonio’s Southwest Research Institute (SwRI) brings Texas the latest example of an intelligent, demand-side resource that can play an active role in the power grid and offset the use of fossil-fuel power plants. Late last month, SwRI announced that its innovative vehicle-to-grid system got the green light from the Electric Reliability Council of Texas (ERCOT), the grid operator, to participate in the state’s electricity market. This system is able to control the charging and discharging for a fleet of electric delivery trucks, meaning that when the supply of electricity struggles to meet demand, the intelligent vehicle charging system can simply stop charging (thus lowering demand). This technology will significantly increase grid reliability, thanks to its quick response time, and effectively deter the need for firing up another dirty power plant.

In order to avoid a blackout, the supply of electricity to the power grid must equal the electric demand from customers. Conventionally, this balance is maintained by power plants that remain on stand-by, ready to respond at a moment’s notice. Every hour of the day, ERCOT precisely controls these power plants to keep the grid balanced. In the process, a power plant has to rapidly increase or decrease its power output, which decreases its efficiency and increases its carbon and pollution footprint, much like an a car revving its engine.

Freezing, Scorching, or Not, Texas Needs More Demand Response

MaritaHeadshotAs we thaw out this week from our most recent arctic blast, Texas’ inexperience with ice and snow has been met with Internet memes and jokes. But dealing with extreme temperatures causes serious strain on our current energy system and exacerbates our “energy crunch,” signifying that the available supply of electricity barely meets the demand for that power.

However, as is typical of Texas, last week our weather was quite pleasant – in the 70s – and strains on the system due to weather events weren’t too much of a concern. Yet the Electric Reliability Council of Texas (ERCOT), the state agency charged with managing the flow of electricity for most of Texas, alerted an emergency situation despite mild temperatures. To avert disaster, ERCOT initiated demand response, “ask[ing] customers to raise thermostat settings to 78 degrees, typically a summer response intended to reduce demand from air conditioners.” A single malfunctioning power plant caused the problem. ERCOT declined to identify the plant involved.

Google Partners with Nest in Race to be Your Smart Home Provider

Marita Mirzatuny

This post originally appeared on EDF's Energy Exchange blog.  

On Monday, Google announced it is spending $3.2 billion to buy Nest Labs, the trailblazing company funded through its Google Ventures program and responsible for transforming “unloved” home products into beautiful, smart appliances. That’s a lot of money for a business with only two products: a thermostat and a smoke detector. Nest is not exactly reinventing the wheel, right? Well, actually they are.

Welcome to the Smart Home

Google’s move is a starting shot in the race to become the go-to smart home provider, putting in place stepping stones to realizing a future in which our homes will become one ecosystem – integrated and functioning as a whole. Customers are looking for smart appliances that can notify you when they are wasting energy or not performing properly. Plus, these innovative technologies provide customers with more opportunities to engage with and benefit from other cost- and energy-saving solutions, like demand response, rooftop solar power and electric vehicles. This puts customers in the driver seat, giving them insight and control over their daily lives in ways never before imagined (even if just to use automated, “set-it-and-forget-it” functionality).
