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.

Austin Energy + Nest: Empowering Texans To Take Control Over Their Own Energy Use And Electric Bills

Source: Nest

If you have been following our Texas Energy Crunch campaign over the last year, you know that demand response (DR) can play a pivotal role in meeting Texas’ energy needs without relying on dirty, inefficient fossil fuels that pollute our air and consume much-needed water.  Simply put, demand response rewards those who reduce electricity use during peak (high energy demand) times, resulting in more money in peoples’ pockets, a more stable and reliable electric grid and less harmful pollution from fossil fuel-fired power plants.

That said, fully harnessing DR in Texas homes has been a bit of a challenge, despite the high electricity prices that result from the scorching summer temperatures.  To understand the issue, it’s important to look at the obstacles emerging technologies often face.  I highlight some of these obstacles in a recent EDF Voices blog and will be diving deeper in future posts.  Namely, the infrastructure to fully enable residential DR adoption isn’t in place, yet.

Energy And Water Are Running Out In Texas, But It’s Not Too Late

As we’ve highlighted in previous posts, water and energy regulators often make decisions in silos, despite the inherent connection between these two sectors. Texas is no exception.

Two very important and intertwined events are happening in Texas right now.

First, the state is in the midst of an energy crunch brought on by a dysfunctional electricity market, drought, population growth and extreme summer temperatures. An energy crunch signifies that the available supply of power barely exceeds the projected need (or demand) for electricity. Texas’ insufficient power supply makes the whole electricity system vulnerable to extreme weather events. An especially hot day (with thousands of air conditioning units running at full blast) could push the state over the edge and force the Electric Reliability Council of Texas (ERCOT), the institution charged with ensuring grid reliability, to issue rolling blackouts.

Second, Texas is still in the midst of a severe, multi-year drought, forcing state agencies to impose strict water restrictions throughout the state. The drought has already had a devastating impact on surface water and many communities are facing critical water shortages.

Although Texas has always had to deal with extreme weather events, we can anticipate even more intense weather as climate change advances. The new climate ‘normal’ makes extreme heat waves, like the historic 2011 Texas summer, 20 times more likely to occur. These extreme weather events heighten the urgency of the energy-water nexus.

West Texas Electricity Prices Skyrocket – Demand Response Is The Answer

Source: ENR New York

The Wall Street Journal recently reported that electricity prices in West Texas skyrocketed over 20% this year.  West Texas is home to the Permian basin, one of the world’s largest oilfields, and energy producers use hydraulic fracturing, or “fracking,” here to unlock vast new oil and gas supplies.  The increased drilling, oil refining and natural gas processing uses large amounts of electricity.

Cheaper electricity supplies are available, but cannot be delivered to West Texas due to transmission bottlenecks, or “congestion.”  The only power that can be delivered is from older coal plants.  This leads to transmission “congestion” charges (i.e., higher energy supply costs caused by the transmission bottlenecks), which commercial and industrial consumers must pay as a surcharge on their monthly electricity bills.  Using these older coal plants leads to more pollution as well because these plants burn fuel less efficiently and have higher levels of toxic air emissions.

The typical solution is to build new transmission lines to access cheaper electricity supplies.  But a better and cheaper approach is to pay consumers for voluntarily reducing their electricity usage when energy supplies are tight.  Known as “demand response,” this solution:

Texas Electric Co-op At Forefront Of Customer Engagement

This commentary originally appeared on EDF’s Texas Clean Air Matters blog.

(Source: Bluebonnet Electric Co-op)

Everywhere you turn these days, you hear someone mention the emergence of big data and how our lives will be more and more reliant on numbers.  Well the world of electric cooperatives (co-ops) is no exception.  Originally emerging out of the establishment of the Rural Electrification Administration, co-ops enabled rural farmers and ranchers to create customer-owned electric utilities in areas that are not serviced by traditional utilities.

I recently visited the Bluebonnet Electric Cooperative (Bluebonnet), one of the Texas’ largest co-ops providing energy to 14 counties, spanning the outskirts of Austin to Houston and boasting an impressive 11,000 miles of electric lines, 83,000 electric meters and 63,000 members.  Who would have thought so much big data is coming out of rural Texas?

What makes this co-op particularly unique is its smart grid, which is attracting some serious attention.

Unlike other traditional utilities, Bluebonnet does not generate any of its own electricity.  Instead, it buys electricity from the Lower Colorado River Authority and CPS Energy, both pioneers for clean, renewable energy.  Because of this, Bluebonnet is able to concentrate its energy (pun intended) on using new technologies to provide reliable power and enhance customer satisfaction.
