Southern Company Goes Big Into Microgrids With $431M Acquisition of PowerSecure

A big payout for a quiet pioneer in behind-the-meter energy systems—and a big move into distributed energy for SoCo by Jeff St. John February 26, 2016 Selected article excepts follow.  Read the full GTM article here. About the acquisition… Over the past 15 years, PowerSecure has quietly built what may be the country’s biggest fleet of microgrids. The Wake Forest, N.C.-based company controls some 1,500 megawatts — mostly backup generators, along with some cutting-edge solar-battery integrations — that help hospitals, data centers, grocery stores, food-processing plants and other big commercial-industrial customers ride through blackouts and shave peak power costs. Now […]

Security Sessions | Municipal Utility Takes Action to Offset Steep Price Increases in New England

by Dean Musser PE   Municipal electric utilities in New England face significant energy cost increases in the coming years due to the retirement of older generation plants and the impact that shifts in the sourcing of generation will have on transmission patterns. Municipal utilities can mitigate the impact of these increases by reducing the amount of energy used across their service areas during targeted high-value periods, including critical peak hours. To accomplish this goal, municipal utilities must be able to do three things: Predict when high value hours will occur on the grid Motivate and empower large energy users […]

Braintree Electric Light Department and Pascoag Utility District Act to Reduce Peak Demand Cost Risk

ICAP and Transmission Costs Managed via ENE Tangent Peak Management ProgramEnergy New England, LLC (ENE), an energy cooperative of municipal electric utilities operating throughout New England, announced that several municipal utilities are implementing the ENE Tangent Peak Management Program to reduce capacity and transmission costs. Braintree Electric Light Department of Massachusetts and Pascoag Utility District of Rhode Island, both ENE customers, are now rolling out the program in preparation of capacity peaks this summer. The annual capacity load peak of 2015 defines the utility capacity cost in 2016‐2017. In addition, monthly transmission peaks affect the utility’s monthly transmission costs. Capacity […]

Electric Retailers Lament Obstacles

May 18, 2015 By Rich Heidorn Jr. GROTON, Conn. — Electric retailers have made progress in moving away from the cutthroat price competition that shaved margins, but restrictions on billing and metering and “organizational inertia” continue to be challenges, a panel told the New England Energy Conference and Exposition last week. Cullen Hay, general manager of Direct Energy’s residential operations in the Northeast and Midwest, said his company used acquisitions to grow in the past, as it joined other electric retailers in seeking price-conscious customers even as their costs went up. Power suppliers have fewer barriers to prevent customer attrition […]

Software to turn solar panels, building controls and backup generators into energy market players   Jeff St. John  March 25, 2015 Lots of utility customers have solar panels, or backup generators, or the ability to curtail or shift energy consumption in ways that can help reduce energy costs. But there’s a big difference between treating each of these systems in isolation, and integrating them to maximize their combined grid-responsive and money-making potential. At least that’s how Tangent Energy sees it. Since its 2009 founding as a solar developer, the Pennsylvania-based company has built a software suite aimed at identifying, controlling and optimizing […]

Dirty ground starts to sprout clean energy projects

Ariel Wittenberg, E&E reporter Greenwire: Monday, January 26, 2015 Ten years after remediation was complete at the E.I. DuPont Superfund site in Newport, Del., the area had few options for reuse. An 18-inch layer of soil capped a landfill where the toxic byproducts of pigment manufacturing had been dumped for decades. A barrier planted between the landfill and a nearby stream prevented the chemicals from migrating. The contamination no longer posed a threat to the environment or workers at nearby factories. But the land wasn’t being used. The cap was protective only so long as nothing penetrated it, making building […]

DuPont Celebrates Solar Power Project in Newport Published: December 6, 2013 2:33 PM Restricted Land Turned to Productive Use Generating Clean Energy Wilmington, DE (PRWEB) December 06, 2013 DuPont today hosted a celebration of the startup of a 548 kilowatt, five-acre solar installation on a former Superfund landfill site in Newport, Del. The solar installation, located at 205 South James Street, Newport, Del., will produce enough electricity to power 60 homes in the Newport community. It will generate about 729,000 kilowatt hours of power per year. After successfully completing remediation at the Newport site, and with the support of the Environmental Protection Agency (EPA) and the […]

Two large solar projects under construction in New Castle County

Solar projects on former brownfields will rank among state’s largest Oct. 28, 2013 7:31 PM Written by Arron Nathans, The News Journal Two solar projects under construction in northern Delaware, both on former brownfields, are expected to rank among the biggest such arrays in New Castle County. The larger project, which will produce 2 megawatts of power, is nearly complete on 7 acres of industrial land at Seventh and Industrial Streets in downtown Wilmington, near the Kalmar Nyckel tall ship. A megawatt is a snapshot measure roughly equal to the amount of power it takes to run 750 homes at any one moment. […]

Staten Island to host hundreds of solar panels on Port Richmond rooftop (photos and video)

Dave Turner, COO of Tangent, said the solar panels on the Port Richmond roof could cover one-and-a-half football fields.

He said the company’s expertise is helping large energy users — like the city of New York and the DEP plant in particular — integrate clean energy generation into their systems.

“On hot summer days when energy demand reaches peak levels, centralized generation is maxed out and transmission distribution lines are stressed, distribution generation facilities like these provide a cost-effective way to maintain system reliability without relying on costly fossil fuels,” he said.
