Duke Energy

December 2013 - The N.C. Utilities Commission (NCUC) has approved Duke Energy Carolina's proposed Green Source Rider. The Green Source Rider is a new program designed for high-energy consuming customers, such as manufacturers and data centers, to match some or all of their energy consumption from new load, such as a new or expanded facility, with energy generated from renewable sources. In order to participate, customers will need to complete an application with Duke Energy Carolinas requesting an annual amount of energy and renewable energy certificates to be produced or procured over a specified term.

Duke Energy Carolinas will then assign the supply source and contract term request with generation from its renewable energy source or with energy procured through a power purchase agreement with a renewable energy supplier. Participating customers will then enter into a three to 15-year contract with Duke Energy Carolinas.

November 2008 - Walmart Stores Inc. has announced its first substantial wind energy purchase in the U.S. Under an agreement with Duke Energy, the company will purchase approximately 226 million kilowatt-hours (kWh) per year, beginning in April 2009. The purchase commitment, representing about 15 percent of the retailer’s energy load in approximately 360 Texas stores and other facilities, will be sourced from a Duke Energy wind farm currently under construction in Notrees, Texas. In addition to the wind purchase, Walmart also has plans to equip up to 22 locations in Hawaii and California with solar panels.

April 2008 - The three large investor-owned utilities in South Carolina—South Carolina Electric & Gas (SCE&G), Duke Energy Carolinas, and Progress Energy Carolinas—will be notifying their collective 1.3 million customers of a new green power option this month. Under the new program, administered by the nonprofit Palmetto Clean Energy (PaCE), customers of these three utilities can purchase renewable energy in 100-kWh blocks for a contribution of 4¢/kWh, or $4 per block. The purchases are tax-deductible. The utilities will pass the revenue on to Palmetto Clean Energy, which is being funded with a $10,000 grant from the South Carolina Energy Office and $30,000 in donations from the three utilities. To supply the program, PaCE will procure renewable energy from wind, solar, and landfill-gas-to-energy facilities in the region. The program is modeled after NC Greenpower, a similar statewide effort launched by multiple utilities in North Carolina in 2003.

September 2007 - The South Carolina Office of Regulatory Staff (ORS) announced a new green power option for customers of the state's three largest investor-owned utilities—Duke Energy Carolinas, Progress Energy Carolinas, and SCE&G. Under the Palmetto Clean Energy (PaCE) program, customers will be able to purchase renewable energy for their electricity needs in 100 kWh increments each month, starting in January of next year. The price of the green power has yet to be determined, but ORS staff estimate that it will cost consumers about $40 to $50 each month to purchase renewable energy for all of their electricity needs. To supply the program, PaCE will procure power from renewable energy sources in the Southeast such as solar, wind, or biomass. The program is modeled after the NCGreenPower program in neighboring North Carolina and will be managed by a nonprofit group established by the state. Collectively, the three participating utilities serve about 1.3 million consumers in South Carolina.

July 2007 - Duke Energy Ohio has launched its GoGreen green pricing pilot program. Under the program, customers can purchase 100-kWh monthly blocks of renewable energy for $2.50, or 2.5¢/kWh, with a two-block purchase minimum. Program revenues will be used to purchase renewable energy certificates (RECs) from within and outside the utility's service territory, and to cover the program's marketing and administration expenses. The pilot program is scheduled to run through December 31, 2008, but may be extended based on customer acceptance and the availability of qualified REC sources.

News Release - Duke Energy Ohio to "Go Green"

November 2006 - Duke Energy Ohio, a retail gas and electric service company serving approximately 650,000 electricity customers in Southwestern Ohio, filed an application with the Public Utilities Commission of Ohio to offer a green power tariff. Under the two-year pilot program, customers could choose to purchase power "from renewable energy and other environmentally friendly energy sources" in 100-kWh blocks at a rate of 2.5¢/kWh. The minimum monthly purchase commitment would be 200 kWh ($5 per month) and customers must agree to subscribe for an initial one-year period.

The company defines green power to include biomass co-firing, incremental improvements in large-scale hydro, and coal mine methane, in addition to wind, solar, biomass, and low-impact hydro. Duke Energy subsidiaries (formerly Cinergy/PSI Energy) also offer green power programs in Indiana and Kentucky.

June 2004 - Advanced Energy announced that seven in-state renewable energy generators have been selected from a pool of 46 applicants to supply North Carolina's statewide green pricing program. Under the new contracts, the NC GreenPower program will obtain a total of 8 million kWh of power annually from a 1.5-MW landfill gas facility, a 150-kW hog waste digester facility, and five solar photovoltaic (PV) systems with a combined capacity of 27 kW. The program hopes to add wind energy to the resource mix later this year. Currently, more than 5,000 customers participate in the program and collectively purchase an average of 17 million kWh annually.

October 2003 - On October 1, North Carolina's electric utilities rolled out a new statewide program that enables customers to voluntarily support the development of renewable energy resources. The NC GreenPower program is available to customers of the state's three investor-owned utilities—Duke Power, Progress Energy and Dominion NC Power—as well as a number of electric cooperatives and municipal utilities.

The program features a "mass-market" green energy product that can be purchased in 100-kWh blocks for $4 per block each month, or 4¢/kWh. A separate "large-volume" product is available to businesses and other customers that commit to purchase a minimum of 10,000 kWh of green power each month—the premium for the large-volume product is $2.50 per 100-kWh block, or 2.5¢/kWh. Customer contributions made to the utilities will be transferred to an independent non-profit organization and are tax deductible.

Program marketing will be supported in part through the North Carolina State Energy Office, which has committed $500,000 in funds over the next two years. The NC GreenPower program has issued a request for proposals (RFP PDF 159 KB) Download Acrobat Reader for renewable energy resources to supply the program.

February 2003 - The North Carolina Utilities Commission approved a stakeholder-developed plan to offer two green power products to utility customers statewide. The first product is a "mass-market" product consisting of a resource mix of new solar, wind, and methane from biomass that will be offered primarily to residential customers at a cost of $4.00 per 100-kWh block or 4.0¢/kWh. The second product is a "large-volume" product that will include a resource mix of new and existing solar, wind, small hydro, and biomass and be offered to larger-volume customers at a "target price" of $2.50 per 100-kWh block or 2.5¢/kWh.

The primary objective of the NC GreenPower program is to promote the use and development of green power generated in North Carolina by offering a simple purchase option to all of the state's electricity customers supported by a statewide advertising and communications campaign. Beginning in the summer, the green power products will be offered by all of the state's electric utilities, including Carolina Power & Light, Dominion North Carolina Power, Duke Power, ElectriCities, and North Carolina electric cooperatives. The program is being administered by Advanced Energy, a Raleigh-based non-profit research organization.

June 2002 - CP&L and Duke Power filed proposed tariffs with the North Carolina Utilities Commission to give customers the option to support the development of renewable energy sources. Called NC GreenPower, the green pricing program will be the first in the nation to be offered statewide. Pending regulatory approval, utility customers can choose to pay an additional $4 per month to support 100-kWh blocks of green power (or 4¢/kWh). The program will be managed by Advanced Energy, a Raleigh-based, non-profit organization, which will distribute the funds collected by utilities to renewable power producers. The program is expected to begin sometime in 2003.
