80% Electricity from Renewables? It’s Possible, but Policy Prevents It

By Paul Stinson / Published: December 18, 2013

This commentary originally appeared on our EDF Voices blog.

If renewable energy is a good thing, then a lot of renewable energy is a very good thing, right? Not exactly, according to recent articles in the L.A. Times and Forbes about challenges posed by the growth of renewables. But, as we’ve pointed out, the issue here is not too much renewable energy, but rather a vulnerable U.S. electric grid built for the last century.

It’s essential to remember the bigger picture in order to arrive at the truth of the matter: If we are to avoid catastrophic climate change, renewable energy is a vital part of the solution. And while an unprecedented abundance of renewable power may raise complex questions about how to integrate these resources, it also underscores the need – and vast opportunity – for critical energy infrastructure improvements. Our response as a nation should not be to shrink from the challenges of renewables, but rather to keep working toward a smarter, more resilient energy system to meet the needs of the 21st century and beyond.

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

By Kate Zerrenner / Published: December 9, 2013

On November 18^th, 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 »

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

Over 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.

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

By Raya Salter / Published: November 27, 2013

Last 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. Read More »

The Arizona Public Service Ruling on Solar: Here’s Why it’s Win-Win

By John Finnigan / Published: November 26, 2013

This commentary originally appeared on EDF Voices blog.

Rooftop solar owners in Arizona will pay higher costs for utility service under a new decision by state regulators, but the increase was much lower than the amount sought by Arizona Public Service, the state’s largest utility company. Both sides claimed victory. The case is part of a growing trend of more states reviewing these charges.

What is net metering?

The case involves a practice known as “net metering” where the utility pays rooftop solar owners for the excess energy the rooftop solar panels send back to the grid. Most states allow net metering. In many states, the utility company pays rooftop solar owners the full price the utility charges for power it delivers to customers. Utility companies claim this price is higher than their actual cost to produce electricity. The rooftop solar industry claims that raising costs would crush a new industry that provides cheap, clean energy and fails to recognize the benefits provided by rooftop solar.

Regulators must find the right balance between utilities and the rooftop solar industry by allowing utilities the opportunity to recover all their costs while ensuring that rooftop solar owners receive full credit for the benefits they provide to the electric distribution system.
