McCracken and his team built Dataport, the world’s largest source of disaggregated customer energy data for university researchers around the world. “We’ve taken a consumer-grade data measurement tool for solar panels, and are using it to operate the world’s largest research database on customer energy use,” he says.
Press Release: Concurrent Design, Inc. and Pecan Street Receive DOE SunShot Initiative Grant for Smart Energy Switch
Pecan Street has already developed and successfully tested the concept in its Pike Powers Lab in Austin. The SunShot award will allow Concurrent Design and Pecan Street to produce and test a more advanced prototype that demonstrates full commercial capability and can serve as a reference design for a new category of residential energy products.
Could smart water meters one day be the norm in Austin?
With the “BluCube” developed by Pecan Street, there’s no need to change out the whole meter. Instead, a new register, with a plug for a transmitter that would send signals to the cube in the customer’s home, is placed on top of the existing meter body. And Pecan Street is working on an even simpler solution: a ring that could fit around any register and links up to a transmitter.

Is This the World’s Most Innovative Neighborhood?
So what's the point of Pecan Street? The anonymized data is collated by Pecan Street using what it calls, "the world's preeminent research network of energy and water customers." This is then analyzed by academics all over the world, giving them a detailed insight into trends in energy usage and how new, innovative technology affects existing infrastructure.
Startup Goes Public With Its Energy Disaggregation Results
Pecan Street’s Haskell noted that large-scale industrial and commercial power users have been using energy data for diagnostic and analysis uses for years. “The kind of work we’re doing is really focused at lowering the hurdle for people to utilize this capability to the point where a mobile app can use this data to save you money in your house, without you having to do much of anything,” he said.
Pecan Street Launches “Check Engine Light” Service for Solar Panel Owners
Free iOS and Android App for Solar Panel Owners with eGauge Systems Launched After Pecan Street Finds Maintenance Issues Usually Go Undetected and Unaddressed for Weeks or Months
How Do You Know Your Solar Panels Are Working Correctly? You Probably Don’t
A new study from Pecan Street has found that most solar PV systems only experience minor issues and that solar PV is largely maintenance-free. But the minor issues can often impede power production for days, weeks or even longer. In most cases, the homeowners had no idea there was a problem. “It’s a minor issue. But by not detecting it, it becomes an issue where you’re losing value on your solar panel even though it’s a $5 issue to fix,” said McCracken, CEO of Pecan Street.
Hinson in ei magazine: Residential Power Quality
As utilities across the country experience an increase in densities of grid-tied solar photovoltaic (PV) installation and electric vehicles (EVs), as well as shifting consumption profiles, an important question emerges: What is the impact of the modern home on overall grid control and stability? Pecan Street has an answer.
GreenTech Podcast: This Data on How Consumers Use Energy May Surprise You
In this week’s podcast, we’ll talk with Brewster McCracken, the CEO of Pecan Street Inc., about the organization’s analysis of consumer energy use, utility efficiency programs and electric vehicle charging.

Smart Grid Project Saves Money and Energy in Texas
Using smart grid technologies, the project provides 1,000 residences, 25 small commercial properties and three public schools energy data in real-time. Customers can now set and track utility bill budgets, use software to manage the electricity use of individual appliances, and even sell energy back to the grid when they are using less than they produce. By integrating smart meters, solar panels, electric vehicles and energy storage capabilities, the project is already seeing the benefits of smart grid integration and providing customers with control over their electric usage.
Time Magazine: Is this America’s smartest city?
The Pecan Street devices are even smarter than smart meters, recording data from different appliances essentially in real time. At any given moment, the Pecan Street engineers–who work in partnership with the University of Texas and local utility Austin Energy–know exactly how much electricity their subjects are using and how that use changes in response to the time of day, weather patterns, even fluctuations in power price.
Bloomberg on the Aging U.S. Grid
Some consumers are raving about the benefits of the smart grid, too. For Austin, Texas, resident Luke Downs, a participant in the Pecan Street project, access to the smart grid has changed his energy life. “Suddenly, I could see what I was doing,” he said. Downs, 44, lives in a 3-bedroom row house in what’s known as the Mueller neighborhood, a planned urban redevelopment on the grounds of Austin’s former municipal airport.

Report: Residential Solar Systems Reduce Summer Peak Demand by Over 50% in Texas research trial
In most markets, rooftop solar panels are promoted as a way for electric utility customers to reduce their reliance on fossil fuel power and — eventually — save money on their electric bill. According to a new PSR Analytics report from Texas-based energy research firm Pecan Street Research Institute, residential solar systems, and particularly west-facing rooftop systems, may also act as a fairly impactful peak demand reduction device for utilities struggling to meet afternoon demand in hot summer months.
GreenTech Media: Are Solar Panels Facing the Wrong Direction?
West-facing rooftop solar panels produced 49 percent more electricity during peak demand compared to south-facing panels, according to a new study from Pecan Street Research Institute. The research is the first of its kind to evaluate the energy production of solar panels oriented in different directions. Pecan Street analyzed 50 homes in the Austin, Texas area. Some had only south-facing panels, others had west-facing panels, and some had both.
