For more than 100 years, the U.S. power system relied on fossil-fueled power plants to meet our growing energy demand. Now, clean energy resources like renewables are quickly changing our energy mix. But what happens when the sun isn’t shining or the wind isn’t blowing? What about when power demand momentarily outpaces supply? That’s where batteries and energy storage come in, offering a fundamental, even disruptive change to the U.S. electricity system as we know it.
Batteries are energy game-changers
Today’s electricity system not only overproduces to be prepared for unforeseen problems, it also deploys dirty “peaker” plants that fire up during those few times per year when electricity demand is high (like during a heat wave) and the electric grid is stressed. With batteries, there’s no need for either overproduction or inefficient backup reserves, ultimately saving both utilities and customers money.
Batteries can provide bursts of electricity incredibly fast, often in milliseconds, and with far quicker reaction times than traditional power plants. As a result, energy storage helps the electric grid absorb and regulate power fluctuations, providing electricity fast, when and where it’s needed. Since the supply and demand of power must be carefully balanced, this ability helps prevent the grid from experiencing brownouts or blackouts. Read More
For 10 weeks this summer, EDF Climate Corps fellow Karan Gupta worked for JLL, a commercial real estate firm, to optimize energy use at one of the company’s largest buildings: 77 West Wacker Dr., a 1-million-square-foot commercial office building in downtown Chicago.
At the core of Karan’s work was demand response – an energy savings tool that pays people to shift their electricity use to times of day when there is less demand on the power grid, or when more renewable energy is abundant.
I spoke with Myrna Coronado-Brookover, JLL’s senior vice president and general manager, to find out why her company placed a bet on this technology. Read More

How does one maintain a facility of 4.2 million square feet, with five acres of roofs, that is two city blocks long and has 375 tenants? And, how does a building built in 1930 (also the largest building in the world at that time) compete with current technological innovations and new energy conservation trends? The answer lies in having accurate data, which can be a challenge considering the sheer size and age of this particular building.
The building I am referring to is the Merchandise Mart. Also called ‘The Mart,’ this building centralizes Chicago’s wholesale goods businesses by consolidating home, office, casual furnishings and a large variety of luxury home kitchen & bath showrooms under one roof. At the same time, the building now forms part of Chicago’s growing tech triangle community near the famous city loop as 1871, Motorola Mobility, Braintree, All Scripts, CCC and Yelp are in the building.
Every EDF Climate Corps fellow can fathom the potential of implementing energy efficiency measures – especially since it is a current industry trend. However, this does not come without challenges. As a student at Duke, I thought putting in long study hours, deskbound in a library only to be chauffeured home by campus safety was difficult.

Energy data collected via smart meters could lead to services that improve people’s lives and cut harmful carbon pollution. This is true if customers have easy access to the energy data they need to control their own energy use and reduce their electricity bills – which isn’t always the case.
When the Illinois General Assembly passed the Energy Infrastructure Modernization Act in 2011, local utilities ComEd and Ameren touted their many benefits, including greater control over peak energy load, electric grid resiliency, and cost savings resulting from the energy conservation efforts of their electricity customers. Now that smart meter deployments are well underway, utilities need to enable the many benefits of smart meters by empowering customers with easy access to their own energy data.
To facilitate this endeavor, EDF and Citizens Utility Board (CUB) joined forces to develop the Open Data Access Framework, a first-of-its-kind proposal, which the groups presented to the Illinois Commerce Commission (ICC) on Friday, August 15th. Read More

Demand response – an energy saving tool that encourages customers to shift their electricity use to times of day when there is less demand on the power grid or when more renewable energy is abundant – has been at the core of my work this summer as an Environmental Defense Fund Climate Corps fellow. My host company, Jones Lang Lasalle, is the property manager for 77 West Wacker Drive, a 50-story office building in downtown Chicago. Here, I am focusing on maximizing the benefits of demand response, which have already been implemented through multiple technologies.
Currently, 77 West Wacker is enrolled in the PJM demand response capacity market through a demand response service provider. As discussed in my previous post, there are standby payments for demand response commitments, meaning that the building is paid for simply making itself available to reduce energy demand when called upon to do so.

Over the next five to seven years, smart grid infrastructure, including advanced metering infrastructure (AMI), will be deployed for customers of the two largest utilities in Illinois: Commonwealth Edison and Ameren Illinois. Over five million new meters will be installed and over $2 billion of smart grid investments will be made. The challenge confronting consumer and environmental advocates in Illinois is how to make sure that infrastructure is rolled out in a way that maximizes other policy objectives—namely, saving customers money on their energy bills and promoting opportunities for innovative technologies like microgrids and energy storage.
Years of discussion in Illinois culminated in the Energy Infrastructure Modernization Act, a new law that supports smart grid deployment and funds programs to support electricity system innovation through: Read More
