New ‘Smart Cities’ Guide Helps Leaders Plan for a Sustainable Future

By Kate Zerrenner / Published: December 9, 2013

Kate ZerrennerOn November 18th, the Smart Cities Council released the Smart Cities Council Readiness Guide at the Smart City Expo World Congress in Barcelona, Spain. I am privileged to be a member of the Smart Cities Council Advisory Board, and in such a capacity, served as a review for the Guide.

The Smart Cities Council Readiness Guide is the first of its kind—a comprehensive, vendor-neutral handbook for city leaders and planners to help them assess their current state of technology and give them a roadmap for developing a smart city.

It was produced in collaboration with some of the world’s top smart city experts and includes technology recommendations for a city’s most important responsibilities: buildings, energy, telecommunications, transportation, water and wastewater, health and human services, public safety and payments.

My reviews were solely of the energy and water chapters, but the Guide as a whole offers a collection of guidelines, best practices and more than 50 case studies as well as 27 proven principles that will enable cities to achieve a smart city status. City planners will be able to identify the best path forward for their particular city, creating a customized plan that will work, even if development of the plan is gradual. Read More »

A Good Day for Clean Energy as President Obama Doubles Down on Renewables

By Jim Marston / Published: December 6, 2013

obamaThis commentary originally appeared on our EDF Voices blog. 

Today president Obama took an important step toward supporting a clean energy future by directing the Federal Government to consume 20 percent of its electricity from renewable sources by 2020.  This is more than double the current level, making this a significant moment in President Obama’s second term.

Renewable energy has become cost-competitive over the years and the quality of innovative clean technologies has dramatically improved.  These are clean, efficient, homegrown resources that we can count on now, and President Obama’s public support of renewables in this announcement will serve to further drive their competiveness in the market.

This memorandum also directs agencies to update their building-performance and energy-management practices, “by encouraging the use of the consensus-based, industry-standard Green Button data access system (Green Button) and the Environmental Protection Agency’s (EPA) Energy Star Portfolio Manager.”  Recommendations under this section ask agencies to install smart energy and water meters, participate in demand response where possible and make the data collected from smart meters publically available in order to better manage energy performance and allow for benchmarking.

Why Residential Demand Response Is a Critical Part of Our Nation’s Energy Mix

By Guest Author / Published: December 5, 2013

Guest Blog Post By: R. Blake Young, President and CEO of Comverge

The complex task of managing peak energy demand is not something that should be addressed in a piecemeal fashion, and this is particularly true in the demand response industry. For reference, demand response (DR) balances supply and demand, providing peaking capacity to utilities without investments in new plants. DR incentivizes change in customer energy usage patterns to reward lower electricity use at times when system reliability is jeopardized or the price of electricity is higher.

While Comverge supports both residential and commercial and industrial (C&I) demand response programs, it’s important to remember that the residential sector is an incredibly valuable and essential part of any energy management program. The infographic below illustrates why residential demand response is so important to our nation’s energy mix. Read More »

Debate Over a Changing Texas Energy Market Heats Up at Senate Natural Resources Committee Hearing

By Marita Mirzatuny / Published: November 27, 2013

Marita MirzatunyOver the past two years, Texas’s changing energy landscape has been a focus of EDF’s work.  In our Texas’ Energy Crunch report from March 2013, we highlighted that Texas has a peak capacity constraint – meaning that the power grid becomes strained when, for example, everyone is using their air conditioning units on hot summer afternoons.  This challenge, coupled with increased climate change and drought, signal the need to prepare by adopting a smarter grid and cleaner resources.

The Public Utilities Commission of Texas (PUCT) and the Electric Reliability Council of Texas (ERCOT) have been engaged in this conversation and various proposals have been laid on the table to determine what Texas’ energy future will look like.  EDF maintains the position that, whatever reforms are made, customer-facing, demand-side resources – defined here as demand response (DR), renewable energy, energy efficiency and energy storage – must play a key role to ensuring reliability, affordability, customer choice and environmental improvements.

Energy-Only Status Quo or Capacity Market or…?

Texas’ current energy-only market structure pays power plants only for the energy they produce.  This is beneficial in that generators are not overcompensated, but the downside is that energy companies aren’t incentivized to build in Texas and energy management providers (DR companies) are not viewed as equal players.  Energy prices are low due to an upsurge in cheap, abundant natural gas and wind – and without a guarantee for a high return on investment, companies will not take the risk of constructing costly new power plants.

Verizon Invests Big in Clean Energy

By Rory Christian / Published: November 27, 2013

This commentary originally appeared on Verizon’s News Center.

Rory Christian PhotoTechnology giant Verizon is making significant strides toward increasing the use of on-site green energy throughout its national portfolio with plans to finish more than $100 million in clean and renewable energy projects across facilities in seven states by the end of this year. The investment is estimated to reduce carbon emissions by over 15,000 metric tons each year, which is comparable to over 2,000 homes’ annual electricity use. Verizon’s video showcasing its plans includes an introduction by Environmental Defense Fund (EDF)’s very own Victoria Mills, managing director of Corporate Partnerships.

The move builds on the company’s earlier foray into clean technology, resulting in Verizon’s successful 2005 investment in a 1.4 megawatt fuel cell in Garden City, New York. Fuel cells use an electrochemical process in which oxygen and fuel (natural gas or biogas) react to produce amounts of electricity. The process produces less carbon emissions than more conventional sources of electricity, and enables the possibility of affordable on-site, user-owned power generation that is as constant and reliable as a utility and provides an attractive economic payback for customers.

When selecting locations for solar and fuel-cell energy projects, Verizon was careful to consider sites with favorable zoning requirements, utility partners and regulatory regimes. Despite being financially viable, identifying suitable projects was no simple task. Financing these projects without incentives at the federal and state levels proved impossible, and the incentives often came with conflicting timetables and were difficult to leverage. Read More »

The U.S. Can Learn from Renewable Energy Integration in Europe

By Raya Salter / Published: November 27, 2013

Raya Salter PhotoLast month I travelled to Amsterdam for European Utility Week (EUW), Europe’s largest “smart energy” conference that was attended by more than 7,000 people, hundreds of exhibitors, utilities, regulators and policy experts.  The theme of this year’s conference was “Pulling in One Direction,” with a focus on greater collaboration between the European power transmission and distribution sectors.  I was invited to speak about EDF’s Smart Power Initiative, which aims to change the trajectory of the U.S. electricity system to help avoid dangerous climate change through smart power policies and clean energy investments.

Why would EUW be interested in EDF’s approach?  Because EDF seeks to knit together key state and regional regulatory agendas to “move the needle” toward a clean and modernized power grid, and to fix the “disconnect” between power transmission and distribution.   Increasing the connection between the wholesale sector (typically has more sophisticated markets including real time pricing) and the distribution sector (has less sophisticated pricing) can unlock the value of smart grid. 

This is one reason why our team seeks to enable smart metering and dynamic pricing for customers on the distribution side.  Dynamic pricing incentivizes the shifting electricity use to periods of lower demand and lower prices (often when clean, low-carbon energy is most available).  Enhancing the flow of information and energy between the wholesale and distribution sector will also empower smart grid solutions such as: reducing wasted energy through energy efficiency and demand response (which rewards customers who use less electricity during times of peak, or high, energy demand) and  increasing the use of clean, distributed generation (like wind and solar).  These innovative solutions will ultimately make the system cleaner, less wasteful and eliminate the need to invest in additional polluting fossil fuel power plants.
