Learn More About How YOU Have ‘Power Over Energy’

Did you know that 40% of the electricity used to power home electronics is consumed while they are turned off? And did you know the electricity it takes to power a single 100-watt light bulb for one year is generated by 713 pounds of coal?

With electricity outlets in every building and gas stations on every street corner, our dependency on energy is undeniable. Still, very few consumers are aware of effective ways to prevent waste and use energy efficiently. To educate consumers, several leading energy and environmental groups have united to create PowerOverEnergy.org, a warehouse of information about energy generation, consumption, impact and conservation.

The site aims to educate, empower and motivate consumers to use energy more wisely and to play an active role in our electric grid’s modernization. America’s outdated energy system is wasteful, expensive and a huge source of pollution. Over the next two decades, utilities will have to invest up to $2 trillion to modernize our electricity grid, most of which is past the age of retirement. A more resilient, smart “green” grid will pay for itself by saving the United States around $20.4 annually by increasing efficiency by five percent, and another $49 billion each year by reducing the cost of power outages.

Environmental Defense Fund, Silver Spring Networks, Sustainable Silicon Valley, Smart Grid Consumer Collaborative, Edison Foundation’s Institute for Electric Efficiency, Global Green USA, GrideWise Alliance and Silicon Valley Leadership Group believe that knowledgeable consumers are necessary, and we’ve joined the Power Over Energy Coalition to arm people with the information they need to join the push toward a smarter, more resilient grid. Empower yourself and those around you by checking out the site and becoming an informed participant in the movement.

Do We Need Breakthroughs Or A Simple “Carbon Diet?”

Over the weekend, The New Republic published an interview with President Obama, where he noted the following: “On climate change, it’s a daunting task. But we know what releases carbon into the atmosphere, and we have tools right now that would start scaling that back, although we’d still need some big technological breakthrough.”  How accurate is the call for breakthroughs and what do we really need?

First, let’s look at where we don’t need breakthroughs, but instead more deployment – energy efficiency, of course, being Exhibit A.  Creative financing, such as on-bill repayment (OBR), at scale can speed up deployment here.  Similarly, unlocking clean energy to reduce carbon emissions from the electricity sector hinges on affordability.  Wind energy is already competitive with fossil fuels, in large part because the cost of wind energy has come down around 65 percent in the last 20 years, according to the National Renewable Energy Laboratory (yes, declining natural gas prices provide new competition, but EIA projects that natural gas prices will begin to increase in 2018, and wind power purchase agreements are signed for around 20 years at a fixed price).  Residential solar is verging on the tipping point for “grid parity,” or the point at which a source of power becomes cost competitive with other sources.  Bell Labs first introduced solar cells in the 1950s.  Environment California’s Research & Policy Center recently reported that they expect solar to reach grid parity in mid-2014 to 2016 at the outset. 

Of course, progress in lowering costs and increasing efficiency comes on the heels of many smaller innovations.  For example, innovations in materials science underlie many of the most promising technology evolutions, such as the role of carbon fiber as a basic raw material for wind turbine blades or the use of Gallium Arsenide wafers to reduce manufacturing costs for solar cells.  But, nonetheless, given our country’s strength in materials science (think of our leadership with companies like Dow, Dupont and 3M), such innovations seem imminently feasible and in my mind don’t require a major “breakthrough.” 

We’ve also delivered numerous hardware and software innovations to transform our electric grid into a more resilient, smart, “green” grid.  Even carbon capture and storage, to some a high stakes technology bet, is actually just a new configuration or application of engineering equipment we have installed and used for decades, such as heat exchangers, chillers, absorbers, pumps and compressors.

Where would I wave a wand for a breakthrough?  A cheap, reliable and efficient energy storage system wouldn’t hurt, one that replaces the clunky compressed air systems or the size limitations of batteries.  But, overall, the declining cost curves for clean energy solutions, due to innovations large and small, tell us an important story:  solving the climate crises is not unaffordable or necessarily a drag on our recovering economy as many fear.  It is certainly not infeasible nor hinging on that one great technological breakthrough. 

We need non-technological breakthroughs.  Like the new head of the World Bank, Dr. Jim Kim, who in Davos described wanting to make “everything the Bank does aligned with the effort to slow down climate change.”  And it is certainly cheaper than repeating the $50 billion recovery price tags that we might face time and again as Superstorm Sandy becomes the new normal. 

Americans love the quick technical fix.  But, today we have affordable answers right in front of us, it’s the willpower we may be lacking.  So, just as most of us believe that rather than wait for a dieting breakthrough, the best answer to weight loss is reduced consumption and more exercise – we need to go on a carbon diet.  Our economic and environmental health depend on it.

Weathering The Storm Next Time: Gov. Cuomo’s NYS 2100 Panel Offers Smart Plan To Keep The Lights On, Emissions Down

Extreme weather and aging infrastructure came together with a vengeance in Sandy, showing the fragility of the basic systems that sustain this vibrant city and region. Like so many others, my family lost power, heat and water during Superstorm Sandy, and I watched out my window as a giant flash marked the moment that waters crested a 12-foot retaining wall at the 14th Street ConEd plant.

New Yorkers are all too familiar with the devastation that followed, and the disruption that spread far beyond the water’s reach. As the immediate crises are resolved, our attention is now on the complex challenge of long-term resilience.

One big step: The NYS 2100 Commission, a panel of experts assembled by New York Gov. Andrew Cuomo back in November, just two weeks after the storm. EDF President Fred Krupp served on the commission, and our energy team prepared extensive recommendations on how to make our energy system more robust, resilient and adaptable. In yesterday’s State of the State address, he talked about the results.

As it turns out, some important solutions were right under our noses.

For example, amid the darkness and devastation, there were dozens of homes, businesses, even whole communities that kept their lights on and the water because they were designed to isolate breakdowns, heal quicker, and work with natural systems rather than against them.

Success stories were located across our region: 

  • Lights stayed on for sixty thousand residents of Co-op City in the Bronx thanks to a combined heat and power plant that can operate independent of the grid. Ditto the office tower at One Penn Plaza, an apartment building at 11 Fifth Avenue, and large parts of the campuses at Princeton and NYU. 
  • In Bayonne, NJ, the Midtown Community School used a combination of solar panels and a generator to offer a safe, warm place to stay for over 50 residents during the storm. 
  • On Long Island, the Villani family kept their lights on thanks to a 4.8 kw solar array that happens to have a battery bank. “We had friends and neighbors coming over to charge phones and batteries,” Stephanie Villani said. 
  • In lower Manhattan, the community group Solar one used solar panels to offer residents of Stuyvesant Town, the sprawling 35-building apartment complex, a place to charge their phones and computers.

Exceptions like these should be the rule next time. Unfortunately, today’s utility grid is set up to discourage more of these success stories – which are also cleaner and more efficient.

In fact, many buildings outfitted with fresh new solar arrays stayed dark thanks to cumbersome, outdated rules and regulations. Ironically, the solar panels were not making electricity when the grid was down, precisely because they were permanently connected to the grid and had to be shut down, rather than simply unhook when the larger system failed. So instead of sunshine, they were running on diesel power – if they were running at all.

Building a smarter grid, and encouraging clean, efficient ‘microgrids’ that provide islands of heat and light means fewer outages and faster recovery. A smarter grid would also have the intelligence needed to pinpoint outages, cordon off damage, and reroute power.

Clearing out the legal cobwebs and requiring utilities to unlock their grids more easily would make their systems stronger and more resilient in a crisis, and open the door for more efficient, renewable energy solutions. It would also open up opportunities for new ways to finance the upgrades needed to take full advantage of efficiency and renewables in today’s buildings.

(You can read EDF’s blueprint for a smarter, more robust grid here.)

Climate change means that higher sea levels and more extreme storms are the new normal. Unfortunately, some of this is already locked in. But we still have an opportunity to prevent the worst, most costly consequences by working together to reduce heat-trapping pollution. Superstorm Sandy reminded us of the need to prepare for a more challenging future. We need to make sure the steps not only protect against the impacts we can’t avoid, but also help prevent those we can.

Yes, we will have to fortify our buildings and infrastructure, change building codes and keep generators on hand in the face of extreme weather. But a lot of the steps we can take to keep the lights on during a crisis are also steps we can take to cut the pollution that is linked to climate change and extreme weather in the first place.

As we invest federal emergency dollars to rebuild, as we get ready for the next time – let’s make sure we’re taking every step that solves for both safety and less pollution at the same time. Efficiency, a smart grid, transparent information, renewables. Unlocking multiple benefits like these can help us rebuild better, faster and stronger. And lead the way for the world’s great cities, many of which are on the coast and in harm’s way just like New York.

My kids and I were lucky to weather the storm with just inconvenience. But as I think about how might live in a future New York City, I’d like to be sure that we’re doing everything we can now to run this town on safe, clean energy. The Cuomo commission report takes a big step in that direction: let’s join the Governor and the members of this commission in making its recommendations a reality. This is an opportunity that business, political and community leaders must not miss.

Pecan Street Inc. Researchers’ Report Receives Outstanding Paper Award

Source: Pecan Street Inc.

With 1.8 gigawatts (GW) of solar power installed in 2011 and an expected 2.8 GW in 2012, it is safe to say that solar energy has solidified its role as an important part of our nation’s energy portfolio. Affordability, competitive financing and reduced greenhouse gases are just a few of the reasons why the number of solar installations has skyrocketed in the past several years.

Now, new research from Dr. Alexis Kwasinski, Dr. Fabian Uriarte, and Amir Toliyat, engineers from the University of Texas at Austin, sheds some light on how rapidly growing solar installations can work with the current electric grid. For their groundbreaking findings in “Effects of high penetration levels of residential photovoltaic generation,” they were recently awarded an Outstanding Paper Award at the International Conference on Renewable Energy Research and Applications (ICRERA) in November for their in-depth research and innovative solutions.

Jump started by a $10.4 million grant from the Department of Energy, Pecan Street Inc. is a “community-wide collaboration to fully reinvent the energy delivery system”  based in Austin, Texas.  This living ‘smart grid laboratory’ provided a perfect data collection site for the researchers. Pecan Street’s leadership focuses on developing new technologies that reinvent the way we create and use energy, so that residents drive electric vehicles, invest in cutting-edge technology and, of course, use solar panels.

The massive amount of data gathered from Pecan Street’s efforts provided researchers the opportunity to analyze solar energy’s effect on the three key characteristics of “power quality” (voltage level, voltage unbalance and power factor).  The researchers found that energy inflections (voltage levels and voltage unbalance) did not create any major concerns with the power grid, despite unfounded claims to the contrary by some solar critics.

Digging further into the data, the researchers unexpectedly found that power factor could become a real issue if solar installers don’t use modern equipment that provides for power factor support.  While the issue could become very real at higher levels of solar penetration, the solution is simple, cheap and currently available; it simply means installers should begin using newer models of solar panel “inverters,” which convert solar power into electricity that can be fed into your grid and home.

Inverters simply convert raw DC power to AC power (i.e. the type of electricity we need to use everyday household items). Maximizing the amount of electricity that is converted into usable power makes solar energy more competitive, ensuring that it will remain an important and growing part of our nation’s energy mix.

It’s exciting to see that these researchers are receiving accolades for their groundbreaking work, and international acclaim is always an excellent motivator for this kind of work, but it’s nice to be appreciated where you hang your hat too.  Fortunately that doesn’t seem to be a problem, since earlier this year Austinites voted in the Best of Austin 2012 award by the Austin Chronicle for Best Way to Turn Some Green Even Greener.  Their choice: Pecan Street Inc.

Smart Technologies Allow For Improved Resiliency During Catastrophic Texas Weather

As we continue to reflect on Superstorm Sandy and its devastating aftermath, it is encouraging to point out how smart technologies can aid in lessening the impacts. While a smart grid will not prevent massive natural disasters from wreaking havoc on communities causing power outages and destruction, it can help lessen the consequences and quicken recovery.

My colleague Miriam Horn wrote a piece earlier this week and said, “We’re already seeing proof these [smart grid] investments can reduce recovery time, keep crews and customers safer, and save lots of money. Thanks in part to federal stimulus grants, a number of utilities are embedding sensors, communications and controls across their networks. On the power lines that it has helped prevent cascading disasters like the one that knocked out power to 55 million people in 2003, when a single Ohio tree fell on a power line. Automated systems can detect a fault, cordon it off and reroute power flow around it.”

Furthermore she states that “digital smart meters, capable of two-way communications, have also proved their worth: providing utilities real-time, granular visibility into their networks, without resorting to (often failing) phones or trucks dispatched on wild goose chases.  Programmed to send a “last gasp” signal when they lose power, those meters have enabled rapid diagnostics – pinpointing exactly which homes or blocks were out, where the break had occurred – and expedited repairs.”

In the DC area, “when the storm struck Monday, Pepco, the utility serving the nation’s capital and its Maryland suburbs, began getting wireless signals from smart meters on its network registering where individual customers had lost power, said Marcus Beal, senior project manager for Pepco’s smart meter program. One of the first movers to install smart meters, Pepco has 725,000 in place and had activated 425,000 of them before the storm struck. Instead of relying solely on customers to call in outage information on specific neighborhoods, Pepco dispatchers can track damage based on smart meter signals that are automatically linked into the utility’s outage map, guiding priorities for deploying repair crews, Beal said. As repairs proceed, the utility is also able to “ping” meters remotely to verify where and when power has been restored. ‘They certainly improve recovery time,’ Beal said, ‘without a doubt. They help to improve the efficiency of the restoration.’”

Here in Texas, we are prone to two main types of extreme weather conditions: hurricanes on the coast and tornados on the plains. Over the past few years we have witnessed the increased intensity of both in Texas and across the US. In 2008, When Hurricane Ike struck Houston as a Category 4, nearly 99 percent of residents lost power, which is about 2 million people.  After 13 days one-quarter of the residents of the fourth-largest U.S. city still did not have electricity.

In 2010, CenterPoint Energy, the utility in the area, began rolling out smart grid updates and said that future hurricane-related electric power outages should be shorter because of smart meters and other grid improvements. In comments filed by the City of Houston to the Public Utility Commission (PUC), a Task Force Report assembled after Ike identified the installation of intelligent grid technology as the ‘best return-on-investment to improve grid resilience and enable storm recovery system-wide’.  Therefore, the Task Force recommended the acceleration of CenterPoint’s intelligent grid deployment in the Houston area. A more intelligent electric grid, combined with smart meter technology, improves reliability by enabling automated self-healing of the grid, which results in fewer outages and faster restoration times for customers. This is crucial for public safety along the Texas Gulf Coast, and in the Houston area, specifically.

For other non-coastal areas in “Tornado Alley” Texas, cyclones can be truly terrifying and unpredictable, like the tornadoes that swept through the Dallas area in April of this year.  While images of tractor trailers and school buses being lifted and thrown like toys are scary, Texans can at least be encouraged by the example of Alabama Power, “which was slammed in April 2011 by 30 tornadoes across 70 miles with winds up to 190 mph. The twisters left 400,000 without power and thousands of poles, wires and substations damaged or destroyed. But by using its 1.4m smart meters to locate the outages and prioritize repairs, the utility restored all of its customers within a week. It also drives 4 million fewer miles each year.”

Across the country, smart meters and grid technologies are being installed, providing more reliability and efficiency in the event of disasters and during normal operations. The Federal Energy Regulatory Commission estimates the percentage of meters in the United States using the new digital technologies increased from 6.5 percent in 2009 to between 13 and 18 percent last year. The IHS consulting firm projects that, by the end of this year, one-third of all meters in North America will be advanced smart versions with two-way communications capability.

Luckily, Texas has 1 million smart meters already installed and is well on its way to 7 million by 2013.

With novel ways of planning, new technologies and innovative infrastructure – from the potential of microgrids enabling community self-sustainability by disconnecting from damaged main grids, and distributed renewable generation letting consumers power back up, to electric vehicles allowing people to avoid the long gas lines and shortages – the future can allow us to be more resilient in the face of catastrophe.

Standing Or Elbow Room In The Energy Sector?

GridWeek 2012 convened earlier this month in Washington D.C., and as a first time attendee, I left breathless and hopeful – yet confused – by inexplicable lingering complacency.  Unbeknownst to me, by agreeing to be a panelist in two sessions, I was setting up a comparative experiment. For the first panel, I spoke on “New Utility Business Models” to a packed room of the glimmer-eyed new energy intelligentsia, which is what makes GridWeek so exciting. In the later days of the conference, about a dozen GridWeek participants interspersed amongst a room of mostly empty seats to hear my panel presentation on “Smart Grid’s Role in New Air Quality Standards.”      

It would seem that I, and the handful of attendees at the air quality panel, see the productive overlaps between air quality standards compliance, smart grid and new utility revenues.   There are several ways that smart grid provides a value proposition for utilities faced with increasingly stringent air quality regulations, most recently the Mercury and Air Toxics Standards (MATS) rule. Here’s a short, but by no means comprehensive, list of both synergies and potential tensions:

  • Renewable Portfolio Standards (RPS): Smart grid supports achieving higher and higher proportions of intermittent, non-dispatchable renewable electricity generation.   Achieving high levels of RPS will be expensive unless we can use new strategies to manage intermittency and power quality.  New pricing structures for utility services can provide incentives to invest on both sides of the meter, and open the door for historically hidden utility services (such as voltage regulation) to be priced and sold.  For incumbent utilities, there is an opportunity to identify and price network services that traditionally have been bundled into rates.
  • Electric Vehicles (EV):  EVs are an important new frontier for utilities, and like most frontiers, offer both promise and peril.  Overloaded distribution networks might keep the utility engineers up at night, while the emerging new customer class has utility shareholders thinking like venture capitalists.  Though still small in number, EVs are quickly driving utility planners and system operators toward a fork in the road. Do we provide safe reliable service to new and existing customers using expensive dirty methods of the past (i.e., more big power plants) or do we take a deep breath (of cleaner air) and trust in the power of the people by embracing distributed energy resources?  
  • Distributed Energy Resources (DER):  Rooftop solar, energy efficiency, and demand response, collectively known as distributed energy resources, unquestionably can provide the low cost, clean pathway towards both energy independence and a sustainable economy.  However, DER is harder to plan and dispatch, and it threatens the traditional utility business models of incumbent institutions.   In California, net energy metering policy has been an important ignition switch, fueled by the California Solar Roofs Initiative, but these successful policies need to evolve to achieve DER at larger scales.   Again, the key is precisely pricing the goods and services on both sides of the meter.  Utilities should be paid for power quality and storage services provided to owners of rooftop systems, while electricity from those rooftops should be priced fairly to provide incentive to invest.
  • Clean air standards:  Oxides of nitrogen, particulate matter, acidifying compounds and carcinogens, such as mercury, are the power sector’s long-time emissions concerns.  Across the nation, electricity generators must hold permits to pollute and tradable emissions allowances that must be acquired at nontrivial prices.   Starting in 2013, California electricity generation that emits global warming pollution will have an associated cost –carbon allowances in the state’s cap-and-trade program.  Already, polluters in Southern California must acquire emissions allowances for the RECLAIM program, and power plants nationwide must comply with the acid rain emissions allowance program established in the Federal Clean Air Act .  Similarly, the Regional Greenhouse Gas Initiative (RGGI) program puts a price on carbon emissions for nine northeastern states, and the Western Climate Initiative is endeavoring to do the same for West Coast states and Canadian provinces.  These programs use emissions allowances that are fungible and tradable, yet they represent real costs – and thus economic opportunity when avoided.  Pollution pricing is changing business models throughout North America.    But there is more to come.  For example, improved environmental performance enabled by smart grid technologies, such as increasing DER, presents new avenues to meet air quality requirements.  For the Environmental Protection Agency (EPA) and other oversight agencies, the ability to measure, verify and enforce DER is key to granting compliance credit, and such capabilities are increasingly cost-effective with smart grid deployment. 
  • Consumer empowerment:  The mobile phone revolution is a prelude to what may be possible once consumers and producers begin to see true pricing in the energy marketplace.  While load-serving entities can find new revenues through services, consumers and entrepreneurs will be motivated by new ways to make a buck, or avoid spending bucks through unnecessary energy waste. 

The new smart grid business frontier has, in fact, many frontiers.  The California Public Utilities Commission conceived of an electricity ecosystem comprised of smart consumers, smart markets and smart utilities.  Utilities are trying to find their new niche within the ever changing food web, and all ears are perked for new opportunities.  That’s why only standing room was available in the business model panel session at Gridweek.

Meanwhile, in the air quality session of GridWeek, there was plenty of elbow room.EPA is considering flexible strategies for meeting new emissions standards for carcinogens.  Many utilities are operating in permit constrained areas that fail to meet National Ambient Air Quality Standards.  Enlightened utilities are seeing demand-side strategies as increasingly viable with smart meter deployment, and a means to improve returns to shareholders.  Performance-based rate of return can be structured to both reduce sales of energy to customer and to improve utility earnings. 

Gridweek revealed to me that many are educating themselves about new business opportunities, but precious few have the connected the dots to air quality improvements.   If I could, I’d bet on the folks who attended both sessions.
