Freezing, Scorching, or Not, Texas Needs More Demand Response

As we thaw out this week from our most recent arctic blast, Texas’ inexperience with ice and snow has been met with Internet memes and jokes. But dealing with extreme temperatures causes serious strain on our current energy system and exacerbates our “energy crunch,” signifying that the available supply of electricity barely meets the demand for that power.

However, as is typical of Texas, last week our weather was quite pleasant – in the 70s – and strains on the system due to weather events weren’t too much of a concern. Yet the Electric Reliability Council of Texas (ERCOT), the state agency charged with managing the flow of electricity for most of Texas, alerted an emergency situation despite mild temperatures. To avert disaster, ERCOT initiated demand response, “ask[ing] customers to raise thermostat settings to 78 degrees, typically a summer response intended to reduce demand from air conditioners.” A single malfunctioning power plant caused the problem. ERCOT declined to identify the plant involved.

Much of this uncertainty and drama can be alleviated with demand response (DR), a novel approach to managing the grid system. Using smart power technology like smart thermostats, utilities can moderately adjust their customers’ energy use in real-time for a brief amount of time to meet the energy needs of all Texans. When energy demand is high, electric utilities can ask customers to voluntarily conserve energy in exchange for cost-savings and even payments. During the polar vortex earlier this month, CPS Energy, San Antonio’s municipal utility, saved about 77 megawatts (MW) of power through demand response programs – enough to power 32,725 homes. Texas isn’t the only place where demand response is taking hold. Read More »

Is Texas the Next Global Leader in Water? It’s Up to State Leaders to Decide.

By Kate Zerrenner / Published: January 28, 2014

This commentary originally appeared on our Texas Clean Air Matters Blog.

The Texas Comptroller, Susan Combs, recently released the Texas Water Report: Going Deeper for the Solution, which proposes a sort of revolution to solve Texas’ water woes. As Combs notes, Texas is a global energy leader, but the state should be a global water leader too. And her initiative couldn’t come fast enough. Texas, already prone to cycles of drought, is facing new water pressures, including population growth and a changing economy, which only make it harder to preserve our diminishing water supply. To rouse the state’s water recovery plan, the report prioritizes water-saving technological innovations (while stressing the need for conservation) and lauds various Texas cities for water management practices. But the report misses some key elements that are essential to keeping our water flowing. In the same way that new energy technologies have brought us closer to a cleaner, more reliable electric grid, innovations in the water arena can seamlessly reduce our water use and set the state on a sustainable path.

The report says conservation is not enough, and it’s right. However, efficiency is the most significant first step and conservation achieved through technology is a welcome counter to the infrastructure-heavy plans typically heard at the Capitol and in the State Water Plan. (What good is a new reservoir, if there’s no water to put in it?) Some of the technologies evaluated in the report include aquifer storage and recovery, inter-basin transfers, low-water fracking technologies and desalinization – what some call “game changers.” These technologies could potentially relieve our future water woes, but these projects are expensive and don’t alleviate our immediate or even mid-term water stresses.

Haze over Dallas Area

Last week, EDF took one more step toward protecting Texans from harmful levels of ozone pollution that have afflicted the state for far too long.

Ozone pollution, better known as “smog,” is one of the most severe and persistent public health problems affecting Texans. Smog causes a range of health issues — including aggravation of asthma and other respiratory illnesses, decreased lung function, increased hospital and emergency room visits for respiratory conditions — and it is associated with premature mortality in urban areas.

According to the American Lung Association (ALA), Dallas-Fort Worth is the eighth most affected area in the country for smog. ALA estimates the city is home to millions of people who are sensitive to ozone-related health problems — including 1.6 million people suffering cardiovascular disease; nearly 1.9 million children; nearly 650,000 elderly residents; and over 520,000 people with asthma.

EDF and its dedicated staff in Texas have long worked to protect Texans from unhealthy levels of smog by reducing the pollution that leads to harmful ozone levels. Most recently, we have been litigating in the United States Court of Appeals for the District of Columbia Circuit to secure important Clean Air Act protections in all areas that are contributing to the serious ozone problems in Dallas-Fort Worth.

Scaling NYC Clean Heat’s Unique Public-Private Partnership for Energy Efficiency

By Abbey Brown / Published: January 27, 2014

Recently, New Yorkers bid farewell to our Mayor of twelve years, Mike Bloomberg. Under Bloomberg’s prevue, EDF helped catalyze the NYC Clean Heat program – which led to the cleanest air the City has seen in the last fifty years. Through NYC Clean Heat’s efforts over the past few years to phase out the use of highly-polluting No. 6 heating oil in more than 3,000 buildings across NYC, sulfur pollution fell by more than two-thirds while soot pollution dropped by a quarter.

NYC Clean Heat has made great strides in helping buildings become cleaner and more efficient, but there is still much work to be done. EDF is wasting no time in capitalizing on the effective public-private partnership we helped assemble of community and union leaders, policymakers and leaders in the utility, real estate and finance sectors to bring more environmental and public health gains to the City. Our next target: All that energy wasted by old and inefficient buildings.

Nearly 40% of U.S. energy is consumed by residential and commercial buildings, which are responsible for more than a third of our country’s greenhouse gases. The building sector presents one of the greatest untapped opportunities for major gains in energy savings and pollution reductions over the next several years. Read More »

What LEED Did for Buildings, This Could do for Shale Gas Production

By Matt Watson / Published: January 21, 2014

Matt Watson Photo This commentary originally appeared on our EDF Voices blog.

The Center for Sustainable Shale Development (CSSD) put out the Open For Business sign today – a key milestone in this innovative effort to up the game on environmental protection in shale gas development. The question now is, will energy companies step up?

We hope so.

CSSD is an unprecedented collaboration – bringing together environmental groups, philanthropic organizations and energy companies to develop performance standards for reducing environmental impacts from shale gas production, and setting up a system so gas producers can have their operations audited and certified against those standards.

CSSD isn’t a substitute for effective regulation. Strong rules and robust oversight is a nonnegotiable bottom line. But we like the idea of upping the ante. Why not have a program that recognizes companies for going beyond the regulatory minimums and doing more to protect communities and the environment? These companies are tough competitors – so let’s make environmental performance part of what they compete on. Read More »

New York Public Service Commission Signals Big Changes to Prioritize Clean Energy

By Elizabeth B. Stein / Published: January 17, 2014

In the last week of December, the New York Public Service Commission issued an Order that signals big changes coming soon to New York’s electric utility landscape. The Commission made it clear that it wants clean energy resources, including on-site, distributed power generation (such as solar PV), energy efficiency and energy load management strategies, to play a central role in how the energy system brings value to customers. In contrast to the peripheral role clean energy resources have played in the past, the Commission is now ready to make them a priority, signaling a willingness to transform the regulatory landscape.

The Order was one of a trilogy arising from three intertwined proceedings, all of which were considered by the Commission on December 19, 2013. One of those three – perhaps the most concrete and immediate – was a proceeding concerning the initial capitalization of New York’s Green Bank, a new entity that aims to advance clean energy funding in New York State. That proceeding addresses a proposal to leverage ratepayer funds and private investment to systematically address market barriers to private financing of distributed generation, energy efficiency and demand management projects, with an ultimate goal of building a clean energy marketplace that can stand on its own. The other related proceedings concerned two New York State programs that draw on the same funding sources that are now being made available for the initial capitalization of the Green Bank: New York’s Renewable Portfolio Standard (RPS) and the Energy Efficiency Portfolio Standard (EEPS).

This Order concerns various proposals to improve and streamline the EEPS programs. Some of these changes are effective immediately, such as the elimination of duplicative reporting requirements. Other, more substantive program modifications – such as the changes to the structure of EEPS and other clean energy programs, as well as the responsibilities of various entities (including the Commission’s Staff, the New York State Energy Research and Development Authority (NYSERDA) and the utilities themselves) – are to be addressed through a new “E² working group,” which is to be formed by February 1, 2014. This new working group is tasked with “sharing and developing concepts for an optimized E² portfolio that supports a scale-up of energy efficiency and overall system efficiency,” for a program launch by the end of 2015.
