Duke Energy is adding power-generating fuel cells to the list of services it provides businesses and institutions.  On Monday, the company's non-regulated subsidiary Duke Energy One announced a $250 million deal with California-based Bloom Energy to install fuel cells at more than 30 businesses in four states: California, Connecticut, Maryland and New York.

Duke Energy last week began generating electricity in eastern North Carolina with natural gas from a new source: hog waste. It helps Duke meet a state mandate, while benefiting farmers, too.

A trade association representing energy organizations in the Carolinas say President Trump's decision to pull out of the Paris Accord will have little immediate effect on local energy companies.

The 10-year plan includes upgrading power lines and systems across Duke's North Carolina grid.

Duke Energy plans to spend an extra $13 billion over the next decade to modernize the power lines and systems that distribute electricity in North Carolina. The upgrades include burying lines, adding technology to reduce outages, and giving customers more energy efficiency tools.

Wind and solar power get most of the attention when it comes to renewable energy. But Duke Energy has another alternative - a type of hydroelectric power called pumped storage. WFAE reporter David Boraks visited Bad Creek hydroelectric station in upstate South Carolina, where Duke is getting ready to invest millions of dollars in upgrades.

Duke Energy has put out a call to renewable energy developers for new projects in the western part of the state. It's part of the company's push to meet a state mandate to generate more energy from sources other than fossil fuels.

The North Carolina Senate approved a bill Monday that would ban wind farms across much of the state. The "Military Operations Protection Act," which passed 33-14, would not allow wind turbines in areas with military training flights.

Duke Energy shareholders elected a smaller board and approved one of two shareholder proposals at their annual meeting Thursday morning.

Duke Energy says it’s on track to beat its goal for renewable energy use over the next few years, so it’s raising the bar. The pledge came in the company’s annual corporate sustainability report out Thursday.

Carbon Cycle Energy

Duke Energy has signed a deal to buy natural gas recycled from swine and poultry waste generated at a new plant eastern North Carolina. The contract helps Duke meet state renewable energy rules and could help solve the problem of what to do with the state's growing amount of animal waste.

North Carolina is continuing to fight new EPA rules that limit carbon emissions from power plants. Gov. Pat McCrory's office said Wednesday night the state has joined 27 other states in asking the US Supreme Court to delay the Clean Power Plan, while the states challenge the rules in court.

Duke Energy plans to add two more solar energy projects to its North Carolina power network next year, as it works to meet state requirements for clean electricity.

The company is asking the North Carolina Utilities Commission for permission to take over two projects already in development -  a 60-megawatt solar farm in Monroe and a 15.4-megawatt facility in Mocksville, in Davie County.

If approved, construction on both would start in March and be done by the end of 2016. 

NC Renewable Energy, And Surcharges, Set To Rise

Duke Energy reports it cost about $30 million to comply with North Carolina’s renewable energy requirement last year. As that requirement doubles next year, Duke is petitioning for an increase in rates.

Duke Energy is in discussion with large companies, including Google and Facebook, to use renewable energy to power new electricity needs in North Carolina. Companies can pay a premium and Duke will pour energy of the companies’ choice—solar or wind, for instance—into the grid to match the amount of power used. The new program sailed through the state utilities commission last month, but some environmental organizations question its potential. WFAE’s Ben Bradford joined Morning Edition host Kevin Kniestedt to explain.


A new report shows North Carolina becoming a bigger player in the solar energy market. The firm NPD Solarbuzz says North Carolina created 400MW (megawatts) of new solar capacity. That’s enough to account for 10 percent of all new solar in the U.S. and Canada. Analyst Michael Barker says it’s a ramp up from previous years.

"One of the big findings was just how quickly the North Carolina market has grown in 2013," Barker says. "Climbing from the 5th largest U.S. market to the 2nd largest U.S. market."

Duke Renewables President Talks Solar Prospects

Duke Energy is not known for embracing renewable energy in North Carolina. About one percent of the Duke Energy Progress’ and Duke Energy Carolinas’ electric capacities in the state come from renewables—mostly solar, as well as a small amount of wind and biomass. Duke’s favored plan projects that number to rise to just 3 percent, 15 years from now. At the same time, Duke has a subsidiary business solely focused on developing and selling renewable energy across the country. WFAE’s Ben Bradford spoke to the president of Duke Energy Renewables for a businessman’s perspective on the green revolution.

When you look out the airplane window as you fly into Charlotte, the trees thin, the Uptown skyline rises into view, and the buildings of West Charlotte grow larger, as your plane drops altitude. The City of Charlotte hopes to add solar panels glinting across the airport’s parking lots and in-between the runways to that view. The city is soliciting bids for an ambitious solar project at the airport.

IKEA-Charlotte Now Operates (Partly) On Sunshine

Furniture giant IKEA has just installed 4,228 solar panels on the roof of its store in Charlotte. The panels are expected to generate up to half of the store's electricity. 


The world’s thirst for more energy has led us down the path to climate change. Some politicians have said that alternatives to fossil fuels may help us reverse that, but the problem is that alternative forms of energy aren't ready on the scale we need. And recently scientists at UNC Charlotte came to an even more alarming conclusion, that the problem is unsolvable. Two of the people working on that project talk about their troubling conclusion, when Charlotte Talks.

Smaller ReVenture Plan Moves Forward

Nov 30, 2012

The developer whose plan to turn Charlotte trash into electricity was squashed by public opposition last year, has now received a permit for a much smaller power plant that will run on sawdust. 

Tom McKittrick's original vision at a contaminated industrial site on the Catawba River was an 80 megawatt plant powered by household garbage.
