This week the California State Assembly will consider Senate Bill 1414 (Wolk). What’s so exciting about SB 1414? This bill will accelerate the use of demand response (DR), a voluntary and cost-friendly program that relies on people and technology, not power plants, to meet California’s rising electricity needs.

DR programs compensate people and businesses who volunteer to use less electricity when supplies on the power grid are tight and/or to shift energy use when cleaner, renewable resources are available. Every time a customer participates in lowering their energy use through demand response, they are rewarded with a credit on their electricity bill.

The implementation of demand response will help catalyze a much needed upgrade to our outdated grid, whose fundamental design hasn’t been updated since Thomas Edison invented it over a century ago. Demand response can empower participants to lower their electricity bills and carbon footprints, improve air quality, allow for more renewable electricity, and enhance electric grid reliability. In a tree of options for modernizing and cleaning up our energy system, demand response is a low-hanging-fruit. Read More »

The Cheapest Way to Cut Climate Pollution? Energy Efficiency

This blog post was co-authored by Kate Zerrenner, an EDF project manager and expert on energy efficiency and climate change.

On June 2, the U.S. Environmental Protection Agency made a historic announcement that will change how we make, move and use electricity for generations to come.

For the first time in history, the government proposed limits on the amount of carbon pollution American fossil-fueled power plants are allowed to spew into the atmosphere.

There are two clear winners to comply with the plan while maintaining commitment to electric reliability and affordability: energy efficiency and demand response.

We’re already seeing pushback from some of our nation’s big polluter states, such as West Virginia and Texas. But the truth is that while the proposed limits on carbon are strong, they’re also flexible.

In fact, the EPA has laid out a whole menu of options in its Clean Power Plan – from power plant upgrades, to switching from coal to natural gas, and adopting more renewable energy resources. States can choose from these and other strategies as they develop their own plans to meet the new standards.

That said, there are two clear winners on the EPA’s menu that offer low-cost options for states that seek to comply with the plan while maintaining their commitment to electric reliability and affordability: energy efficiency and demand response. Read More »

CPUC Singing the Right Tune on SONGS, But Southern California Still Needs to Harmonize to Achieve a Clean Energy Future

rp_Navarro_Lauren-228x300.jpgLast week, the California Public Utility Commission (CPUC) finalized an important decision for Southern California’s energy supply following the closure of the San Onofre Nuclear Generating Station (SONGS). The plan emphasizes increased reliance on clean energy in this part of the state – an important step towards a fully realized low-carbon future.

The decision authorized San Diego Gas and Electric and Southern California Edison to procure at least 550 megawatts (MW) of ‘preferred resources,’ which include renewable energy, demand response (a tool that’s used by utilities to reward people who use less electricity during times of “critical,” peak electricity demand), energy efficiency, at least 50 MW of energy storage, and up to 1,000 MW of these resources altogether.

That’s a major step forward, as utilities across the country traditionally rely on large fossil fuel plants to meet regional demand. Read More »

At a Key Moment for Energy, California Should Seize Demand Response

This commentary originally appeared on EDF's California Dream 2.0 blog. 

Traditionally, if an area’s population grows — or it loses a power plant — it needs more energy. But California and some other states can approach it differently and reduce the use of fossil fuels.

Instead of asking, How can we add more energy?” the real question becomes “How can we reduce demand?”

Two words: Demand Response (DR).

DR is an incentive that has been proven to work on the East Coast and elsewhere, encouraging energy users who voluntarily participate to reduce their electricity usage temporarily when demand could outpace supply.

Recently, the California Energy Commission’s Integrated Energy Policy Report (IEPR) Draft recognized DR as a technology with a high potential to maximize energy efficiency. This report comes at an important time for the state, when greenhouse gas emissions from large facilities have increased in California after decreasing the previous years, in large part due to the closing of the San Onofre Nuclear Generating Station (SONGS) power plant.

In our recently submitted comments, EDF commended the Commission on thinking big on demand response, a cutting edge load management technology that can lower wholesale energy prices when they are highest, dramatically minimize system costs, and reduce air pollution and greenhouse gas emissions.

In their report the Commission also acknowledged that while DR is a great tool if used well, there still “has been little progress towards increasing the amount of DR used in the state.”  The Commission included several recommendations to bolster DR going forward, which EDF supports and will advocate for.

We also made suggestions for how the Commission could maximize the use of DR in California, including:

Time of Use (TOU) tariffs allow customers to pay prices for energy that depend on both when and how much they use. By giving customers the option to save money for reducing their energy use at peak times, older, less efficient peaker plants aren’t used as much and the overall system costs go down dramatically. If half of Southern California Edison’s ratepayers adopted its voluntary TOU program, this would replace the need for two thirds of the San Onofre generating capacity.

  • Set clear and ambitious goals for demand response in the state

The Commission should set ambitious benchmarks in regard to demand response capacity.

  • Foster consumer adoption of innovative demand response technology

Modern technology allows for automated thermostats, ‘set it and forget it’, and other options for easy to use systems that allow interested electricity customers to quickly and consistently respond and reduce energy use when demand is high and the grid is stressed. The Commission should plan to increase consumer uptake of these technologies.

  • Support new technologies and quick scaling up of pilot projects

Demand response opportunities exist on a broad scale in California.  Innovative ideas like charging electric cars when solar power is abundant to help maximize the benefits from renewables are still being developed. The Commission should encourage and support these new technologies, and look for successful pilots that are both cost-effective and fully scalable.

  • Establish effective enforcement mechanisms

By putting in place proper monitoring and enforcement mechanisms, the Commission will help ensure expected environmental benefits.

The Commission’s IEPR is a great step forward, and comes at a key moment for managing California’s energy system. We urge the Commission to continue its work with other stakeholders to increase this momentum, and to utilize its authority – such as appliance and buildings standards and electricity forecasting – to help implement the state’s vision for demand response.

Keeping It Clean: California Should Use Clean Resources To Integrate Renewables

This commentary originally appeared on EDF's California Dream 2.0 blog.

As the 8th largest economy in the world, California remains a global leader in clean tech investment, innovation and adoption of landmark climate and energy policies. What defines our success?  Our ability to try things first, set the bar high, and get policies right.

California’s Renewable Portfolio Standard (RPS) is a perfect example of that bold, pioneering spirit. Passed in 2011, the RPS required that 33% of electricity come from renewables by 2020 – a lofty benchmark, even by California’s standards. Along with self-generation and solar rooftop programs, California is successfully adding solar, wind, and other distributed generation to its resource portfolio.

In fact, renewables are successfully becoming a large part of daytime energy production, the California Independent Systems Operator (CAISO) – the organization in charge of balancing the statewide grid – is concerned over how to make up for that energy when the sun goes down while evening energy demand spikes.  The question is: How can the CAISO reliably integrate renewables?

The CAISO is currently figuring out how to address this need for “flexible” power and will have a draft decision out on October 2nd.  Just like people prefer to take routes they know well when they drive, the CAISO is most comfortable with what they know: familiar fossil fuels. Using clean resources and demand response instead is new territory for them that will require careful orienteering.

California Follows Smart Meter Best Practice: Proactively Address Public Concerns

This commentary was originally posted on the EDF California Dream 2.0 Blog.

Energy powers our economy. But our outdated energy system is wasteful, expensive and a major source of pollution, leading to the deaths of approximately 60,000 Americans per year. Utilities in California and across the country are now investing billions of dollars to modernize that infrastructure, making use of the information technologies that have revolutionized so many other realms of our lives. The smart grid they're building will improve air quality and the health of millions of Americans affected by air so dirty it is often dangerous to breathe.

Smart meters are a key component of the smart grid. They unlock air quality, climate pollution and public health benefits by enabling two-way, real-time communication that gives households, small businesses, manufacturers and farmers (and the utilities that serve them) the data they need to cut energy use and electricity costs. These devices help ensure that every day energy users reap the many benefits of the smart grid.

Yesterday, the California Public Utilities Commission (CPUC) approved a proposal by Pacific Gas & Electric (PG&E) that allows customers to keep their analog meters and opt out of using the new wireless smart meters. This decision is designed to address concerns of individuals who describe themselves as having electromagnetic hypersensitivity to radio frequencies (RF), and report getting headaches, fatigue, nausea and insomnia from exposure.

The radio frequencies used by smart meters are now pervasive in our lives, emitted by our cell phones, microwaves, baby monitors, and numerous other devices we use daily. To understand the potential health risks associated with use of these devices, EDF has completed a thorough review of the scientific literature on the potential effects of electromagnetic and radio frequencies (EMF/RF) on human health. We have reviewed reports from the World Health Organization (WHO) and the California Council of Science and Technology (CCST). We also consulted with outside experts, including Dr. Leeka Kheifets, a Professor in Residence at UCLA who sits on the Standing Committee on Epidemiology for the International Commission on Non-Ionizing Radiation Protection.

The WHO review states that “in the area of biological effects and medical applications of non-ionizing radiation, approximately 25,000 articles have been published over the past 30 years. Scientific knowledge in this area is now more extensive than for most chemicals.” These studies, it concludes, find that “current evidence does not confirm the existence of any health consequences from exposure to low level electromagnetic fields.”

The WHO assessment spotlights the importance of conducting rigorous scientific research to evaluate environmental and health problems, a core principle of EDF. Our policies are based on the best available science and are altered as necessary when new evidence comes to light.

This research helped inform EDF’s position that the limited RF exposure levels associated with smart meters should not result in reduced support for the smart grid, especially in light of the significant health benefits it will deliver by enabling far less use of fossil fuels and far greater reliance on clean, renewable energy, including small, community-based generation like rooftop solar PV.

Today’s ruling strikes the proper balance: sustaining progress toward a smart grid with its multiple public health benefits while addressing individuals’ concerns. It gives consumers the same type of choice about what technologies to use in their everyday life.

We support the PUC's decision and continuing research on the possible health effects of radio frequencies.
