There are many conceptions of the smart grid; what it is and what it should do for us – the “ratepayers” – who will finance the necessary upgrades to California’s electrical system. I find the concept of a “smart grid ecosystem” — with smart customers, smart utilities and smart markets — to be a helpful guidepost as we seek to evaluate what should be accomplished by the utilities trusted to deploy our smart grid.

Ecosystems achieve resiliency through diversity. We want a variety of clean energy resources on the supply side – hydropower, wind, solar photovoltaic, solar thermal – spread across a variety of locations (but never too far from customers). Similarly, on the demand – or customer – side, Californians, buildings, appliances and electric vehicles create an intricate, synergetic web that can be made more efficient and flexible with customer education and empowerment, customer-focused energy pricing policies, and demand response (which allows customers to voluntarily reduce peak electricity use and receive a payment for doing so in response to a signal from their electric utilities).

There are other ways to contemplate diversity in the energy context: Unlike some other states, most Californians can’t choose their power providers, though they can choose among rate “plans” (which are payment schemes, not plans to help manage energy use and costs). EDF recognizes that a smart energy marketplace will thrive with a greater variety of competitors, products and services, and would like to see “3rd party energy service providers” able to participate (that catch-all term includes organizations that deliver energy services and products to customers at a variety of levels throughout the smart grid ecosystem).

Yesterday’s announcement by Nest Labs (Nest) is more proof that the smart grid ecosystem is alive and well. With utility partnerships in California and Texas, among other places, Nest uses their intelligent, WiFi-connected thermostat to help customers smartly and painlessly trim energy use by learning, and mimicking, their temperature preferences automatically. For example, the Nest’s Seasonal Savings services will alert your thermostat when new rates apply with a change of season and the device will begin slight adjustments to presets to adapt to predictable weather trends.

Even more exciting is Nest’s Rush Hour Rewards service that provides centralized, automated small reductions to heating or air conditioning at times of peak demand, when energy use is highest. The offering in particular is designed to enable customers to be good environmental stewards by enrolling in peak energy trimming programs, such as Southern California Edison’s Peak Time Rebate rate. Another benefit of participation is lower energy bills.

While customers retain the ultimate authority to override thermostat settings, the basic premise is to accept a payment to adjust settings by a couple of degrees when the electric grid is most stressed. The trouble is involving people in energy conservation actions is less reliable and slower than communicating directly to appliances with computers. Enter the Nest, strategically located at the interface between utility and customer, with specific dominion over the biggest energy hog in your home – the heating and cooling system.

The reality is that the electric grid as we know it is changing, driven by California’s quest to secure an environmentally safe and affordable energy system. Increasing the amount of clean, renewable energy on the grid will mean that more generation is variable (meaning electricity output from solar and wind depends on sunshine or windiness, respectively). Up to this point, California has met this challenge by backing up clean resources with dirty fossil fuels.

Smart grid ecosystems can provide hot beds for innovation, like Nest’s learning thermostat, but they must start by getting energy pricing right. Nest’s business model will thrive when residential customers see time-variant prices (where the price customers pay reflects the cost of electricity produced at a given time of day) that align with the actual costs of delivering power. We’ve already seen it work in large, statistically-valid studies.

This is how Nest’s learning thermostat will make a difference to your electricity bill and the environment:

1. Customers would upgrade their old programmable thermostat,
2. Customers would sign up for a time-variant electricity rate (perhaps at the same they are online for the utility rebate on the new learning thermostat),
3. On peak demand days when electricity use is highest and the utility will pay consumers handsomely to trim their energy use for a few hours, Nest Labs will signal customers’ thermostats via WIFI. It’ll feel to customers like an air conditioner turned up a few degrees when it’s over 100 degrees outside (aka, hard to notice any difference).

For California overall it will add up to avoiding more harmful pollution from fossil fuel power plants in the coming years and, eventually, could be tuned to work harmoniously with variable clean energy resources like wind and solar. Nest thermostats are among a growing number of products capable of precooling buildings in advance of peak electricity demand, a strategy that will become commonplace once time-variant pricing pervades.

California has already spent billions of customer dollars installing a robust digital metering infrastructure – and it’s time to put these meters to work by enabling customers to participate in demand response and other demand-side programs, such as building weatherization. Coupled with technologies that now allow for fast, reliable, automated ‘set-it-and-forget-it’ adjustments to electricity use – like Nest’s learning thermostat and other exciting energy innovations – we can seamlessly integrate variable clean energy resources, such as wind and solar. In California’s energy ecosystem, customers can now choose to actively, or passively, be part of the clean energy revolution without leaving the comfort of their own nests.

In a February Wall Street Journal article (“California Girds for Electricity Woes”), reporter Rebecca Smith gives an alarmist and misleading account of California energy regulators’ efforts to secure a cleaner, less expensive, more reliable electricity grid.  Right now, California has plenty of power:  44 percent more generating capacity than it typically uses, including a considerable fossil fuel energy portfolio.  Renewables – large scale, rooftop solar, wind, and, increasingly, energy storage – make up almost 15 percent of the grid, a percentage that will more than double in the next decade.  These clean, innovative energy technologies are working to improve the system by reducing the need for fossil fuels.

The reality is that the grid is changing, driven by California’s quest to secure an environmentally safe and affordable electricity system. Increasing the amount of renewable energy on the grid will mean that more generation is variable; electricity output from solar and wind depends on sunshine or windiness, respectively.    Up to this point, California has met this challenge by backing up clean resources with fossil fuels.  But California’s ratepayers can’t afford to keep doing this, so instead of “girding for woe,” the CAISO and the CPUC met to proactively address our changing future – to move California towards cleaner, less expensive electric grid planning.

This new approach can increase California’s ability to rely on clean energy generation by building greater flexibility into the system – while giving more options to consumers.  Not only can customer-based (“demand-side”) clean energy technologies reduce reliance on polluting power plants, they are quite likely to be more reliable and are potentially more cost-effective.   Demand response, or the ability of customers to choose to save money by responding to a price or electronic signal from the grid operator in times of excess system demand, will be key to integrating large amounts of intermittent solar and wind without back-up fossil or storage.   In fact, during afternoon peak demand, where supply is extremely limited in its ability to serve load, the addition of virtual generation resulting from the participation of DR into the market will actually lower energy prices.

California has already installed a robust digital metering infrastructure – and it’s time to put these meters to work by enabling customers to participate in demand response and other demand-side programs.  Coupled with technologies that now allow for fast, reliable, automated ‘set-it-and-forget-it’ adjustments to electricity use, we can seamlessly integrate variable electricity resources, such as wind and solar, without disrupting energy users.  Customers can choose to become an energy resource instead of fossil fuel plants. 

Other “smart” resources could also help to integrate renewable resources, including weather forecasting, scheduling energy at shorter time intervals, and sharing the variability in the output of these generators across large geographical regions to smooth out local variation.   While these tested technologies would be newer to the California grid, the truth is that conventional fossil fuel facilities are subject to far greater extreme ranges of temperatures than wind and solar.  They fail much more frequently, and have to be taken off line for regular maintenance. But the grid was developed to manage these large forced outage rates, and the costs of handling these uncertainties at great cost to ratepayers the grid.  Clean resources, coupled with greater flexibility, can create a far more reliable and less expensive system.

California’s regulators should amplify efforts to put in place the right set of solutions to integrate renewable resources – clean energy resources like demand response and other customer-based resources.  The story isn’t about having too much solar and wind.   It’s about how traditional fossil fuel power plants aren’t viable if we are to protect the environment and ensure a flexible, reliable and sustainable clean energy economy.  This meeting of California regulators was one step forward towards integrating clean, resilient, homegrown resources by empowering consumers and sparking the investment and innovation needed to power California’s future.

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.

San Diego Gas & Electric Co. (SDG&E) and Sudberry Properties have announced plans to incorporate breakthrough smart grid technology in the construction of Civita, the new master-planned development in Mission Valley, California. With a focus on sustainability and energy-efficiency, the “smart energy community“ will be home to vehicle charging stations, solar and fuel cell electricity, battery storage and energy management tools for residents.

"The Civita project is consistent with what we are trying to achieve here in San Diego," said Mayor Jerry Sanders. "By integrating solar power, clean transportation and energy efficiency into the very foundations of our homes and businesses, we can help preserve the environment while strengthening our community overall."

With plans to build nearly 5,000 homes and around a million square feet of office properties, apartment living, public parks, and a civic center over a once 230 acre gravel quarry, Civita could become one of the first communities in the nation to be “fully upgraded with smart grid technology and stand at the forefront of the broader transformation of the electric grid the community.” Civita aims to surpass current California energy efficiency standards by at least 15 percent by using energy star appliances, highly efficient residential lighting and onsite power sources, and by allowing some buildings and areas within community to operate independently of the grid.

Californians are poised for a more functional, data-driven model for setting the prices people pay for electricity.  The new model will make the massive differences in costs of providing electricity during the course of a typical day more evident to us as energy users, thereby inspiring more efficient use of electricity resources.

The California Public Utilities Commission (CPUC) started a rulemaking to examine if the current rate structure for residential energy users is fair and equitable across customer classes and if it:

• supports statewide-energy goals;
• facilitating technologies that enable customers to better manage their usage and bills;
• enables conservation and efficiency on the customer side of the meter; and
• increases the reliance on non-fossil based generation to reduce overall greenhouse gas emissions.

We know already that the short answer is “no”, so CPUC is eyeing a transition to time variant (“dynamic”) rates.  According to Pacific Gas & Electric (PG&E), with time variant, or what is often referred to as “time-of-use”, pricing – rates “will be higher during summer weekday afternoons when electric demand is higher, typically noon to 6 p.m., May through October. In return you’ll pay lower rates at all other times. This means that when you use energy is just as important as how much you use.” 

EDF’s Energy team has been, and will continue to be, closely involved in the CPUC’s rulemaking, which will examine several facets of the current system.  EDF has also been involved in the related smart grid proceedings, such as the deployment of smart grid infrastructure – which provides the ability to both measure energy use in real time and inform customers about the costs (and environmental impacts) of their choices to use electricity at different times of the day.  This Advanced Metering Infrastructure (AMI) enables a smoother transition to dynamic rates for residential consumers.

EDF is very encouraged that the CPUC is considering  time variant pricing because it will help consumers to be more thoughtful about their energy usage, particularly at times when demand is peaking and pushing electricity supply sources to their limits.  This type of rate structure can encourage conservation and reduce peak demand while providing customers with more choices that can ultimately lower their monthly bills.  For example, allowing consumers to see how much they can save on their electric bills by reducing their energy use during peak hours will encourage a shift of energy-intensive activities, such as washing and drying clothing and dishes, to off-peak (and less expensive) times of the day. 

Because a dynamic pricing system will alleviate pressure on the electric grid during peak demand, it will also lead to a more stable, less expensive energy system that is increasingly resilient to extreme weather events.  The economic motivation should also help to create an easy way for consumers to make decisions more efficiently, thereby lowering their electric bills and shrinking their environmental footprints.   

Futhermore, dynamic pricing can help integrate renewables and electric vehicles into the electric grid by allowing utilities to respond to price signals more effectively.  For example, time-of-use rates support electric vehicle charging at times when grid resources aren’t strained, such as late at night or early in the morning when most people are sleeping. 

This new approach will facilitate conservation and energy efficiency, as well as an increase in the use of clean energy sources that avoid harmful greenhouse gas and urban air pollution.   If adopted, the dynamic pricing model can be a common sense approach to saving energy and money, while promoting energy efficiency and a smarter, “greener,” electric grid country-wide.

Increasing energy efficiency (EE) and renewable energy are two ideal ways to cut climate pollution. Yet financing for these types of projects is often limited.

California has proposed using on-bill repayment (OBR) to help close a financing gap for EE that some have estimated to exceed $10 billion annually. It would be the first statewide program of its kind in the country to use third-party financing to fund energy-related upgrades for any type of building.

The program allows private loans for building efficiency upgrades and renewable energy projects to be repaid through utility bills. Billions of dollars could be made available at attractive terms for a variety of buildings, including single-family homes where owners are upside down on their mortgages, small businesses, large commercial properties and multi-unit rental buildings.

At next week’s Good Jobs, Green Jobs Western Regional Conference in Los Angeles, a panel of experts will discuss how the program can make energy upgrades more affordable and create good, green jobs. This workshop will feature a description of OBR, provide a status update on regulatory developments, and consider program design tradeoffs.

The workshop, “On Bill Repayment Solves the Financing Puzzle,” will be hosted by Environmental Defense Fund (EDF) and moderated by our Chief California Economist, Jamie Fine. Brad Copithorne, EDF’s energy and policy specialist who designed the program will describe how it works and how energy users can take advantage of the program to save money on energy bills and hedge against higher energy prices.

Other panelists include: Gretchen Hardison, Environmental Affairs Officer, Los Angeles Department of Water and Power; John Rhow, Director, Barclays Capital; and Neil Alexander, Account Manager, Utility Solutions Group, TRANE. These experts will share their perspectives on the program, and how it can be designed to meet the unique needs of their constituencies.

EDF looks forward to hosting the panel and discussing ideal ways to shape the final program. We are expecting California’s Public Utilities Commission to soon decide whether to offer OBR to all utility customers as a way to reduce energy use, grow the economy and protect public health and our environment.

On Wednesday, I attended a presentation of the Green Button at EMC2, hosted by Silicon Valley Leadership Group, OSIsoft and SolarCity, and moderated by Aneesh Chopra, U.S. Chief Tech Officer and Advisor to the President.  

In essence, Green Button 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.  Customers can then upload the data into software applications, or give it to consultants that provide services such as identifying how to save money by using less energy. 

All of the big California utilities – SCE, SDG&E and PG&E – have embraced the concept and will offer the Green Button to their millions of customers. There is a hope that utilities across the country will also adopt it.

One presenter observed that Americans, on average, waste 20% of the energy that they purchase. This creates a huge opportunity to save money on energy and help to protect the environment by avoiding demand for energy generated by dirty sources, including coal-fired power plants.

Yesterday’s event revealed what can be accomplished when software innovators, government leaders and utilities focus on a common goal. Chopra is widely recognized as an IT innovator in government and he challenged the utility industry to develop access to consumer data in September 2011. Now Green Button is a fully operational, widely embraced standard that will provide a buffet of energy use data for hungry software application developers. 

Testimonials were provided by up-and-coming CEOs in the energy sector, including oPower, Tendril, Lucid Design Group and Simple Energy.  Each company demonstrated how Green Button will drive innovations in energy use software applications.  For example, Tendril announced that its platform, Tendril Connect, will “connect utilities and energy service providers, consumers and app developers to achieve smarter energy usage.”

One question I was left with was, “just how green is the Green Button?” Currently, only the color pallet is green; no pollution information (such as greenhouse gas emissions) is associated with the energy use data. 

While Dr. David Wollman, Deputy Director of Smart Grid & Cyber-Physical Systems, and Manager, Smart Grid Standards and Research at the National Institute of Standards and Technology (NIST), indicated that the Green Button standards do have accommodations for emissions information, there will need to be positive pressure to fully develop that piece of the button. 

And that’s where EDF and you can come in.  We need to encourage efforts to rigorously link emissions information with energy use, in both time and place.      

As part of EDF's smart grid work, we are working with utilities, regulatory agencies and third parties in California and across the country to ensure that innovators have access to an emerging and competitive utility market.  Access to standardized energy use data is an essential piece.  Why?  So they can provide consumers with new tools that help them better understand and manage their energy use, which can save money, cut pollution and help protect the planet.

There’s something happening here. What it is, is perfectly clear: the smart grid is creating jobs in Silicon Valley and across the San Francisco Bay Area, according to a report just released by the Silicon Valley Smart Grid Task Force, which EDF oversaw as an advisory council member.

A well-respected research firm, Collaborative Economics, asked local businesses about their jobs in the smart grid sector. The results are early since the smart grid is still mostly in the planning stage but indications suggest it’s a job-engine that California can rely on.

The report divides the industry into four sectors:

1. power management and energy efficiency,
2. energy storage,
3. local clean energy (distributed generation such as rooftop solar, small wind turbines, plus equipment manufacturing and installation), and the
4. delivery of electricity (transmission and distribution).

During the depths of the recession from 2008 to 2009 when national unemployment doubled from 5% to nearly 10%, smart grid employment in Silicon Valley actually grew.

Manufacturing jobs in the industry are shining brightly against the dark cloud of declining blue-collar employment in the state. Today, more than half of the 12,500 smart grid jobs in the Silicon Valley are in manufacturing.

Investment activity across the diverse smart grid sectors has been robust since 2005 and with strong venture capital (VC) investments. California accounted for 69 percent of total US VC investment in 2010 and total amounts increased 66 percent from 2009 to $2.8 billion.

Investor interest in smart grid is no surprise, since the potential benefits of smart grid are significant and potentially very lucrative:

• cleaner air,
• reliable electricity supply,
• low-cost electric vehicle charging, and
• energy independence by way of local clean energy.

At the press conference where the report was released, San Jose Mayor Chuck Reed captured the importance of the smart grid when he said that many of the city’s Green Vision Goals for jobs, electric vehicles and renewable energy will only be reachable with a smart grid.

Another reason the Bay Area is creating smart grid jobs is that many of the companies at the heart of the region’s economy – information technology giants such as Oracle, Cisco, and Google, energy companies such as PG&E and Calpine, and technology leaders such as GE and Honeywell – are all at the smart grid frontier.

Consumers have rightly asked, ‘what can smart grid do for me?’ In addition to the many environmental benefits, smart grid means empowerment, both in the traditional electrical sense and now in terms of controlling one’s energy use and costs. Now we have another answer: your next job might be helping to build the smart grid.
