The Tennessee Valley Authority (TVA) and DuPont partnered to generate power and steam at TVA's Johnsonville site in Humphreys County, Tenn. The two companies recently agreed on a plan to convert an existing, limited-use combustion turbine at Johnsonville into a highly efficient combined heat and power, or CHP, plant. With TVA retiring the last four coal-fired units at Johnsonville by the end of 2017 under its clean-air agreement with the Environmental Protection Agency, a new steam source had to be found.
combined heat and power
The industry’s transformation has begun. Should the F40 transform too?
The Minnesota Department of Commerce selected Microgrid Institute for a two-part project addressing combined heat and power (CHP) stakeholder engagement in the state. The project includes a pair of contracts to perform work that will assist the Department of Commerce, Division of Energy Resources, in its efforts to develop a CHP Action Plan for the state. Microgrid Institute’s work under the contracts will include facilitating CHP stakeholder engagement meetings and performing a series of stakeholder surveys.
How to find value in distributed energy resources.
Developing a leadership role for utilities in alternative technologies.
How advanced distribution management systems are key to integrating distributed resources.
What every real property owner should know.
Financing has been scarce for distributed generation. But as opportunities expand, commercial frameworks are solidifying. Power purchase agreements are paving the way to a bright future for DG.
Technology is changing the game. Is your utility ready?
Although today microgrids serve a tiny fraction of the market, that share will grow as costs fall. Utilities can benefit if they plan ahead.
Refining the business case for advanced distribution investments.
As utilities plan their capital budgets for the next few years, investments in advanced distribution systems face an uncertain future. Customers question the value—and propriety—of some programs, while long-term strategic goals depend on seamless integration. What will be the path forward for smart grid technology?
Five forces are putting the squeeze on electricity consumption.
It’s tempting to attribute the recent slowdown in electricity demand growth entirely to the Great Recession, but consumption growth rates have been declining for at least 50 years. The new normal rate of demand growth likely will be about half of its historic value, with demand rising by less than 1 percent per year. This market plateau calls for a new utility strategy.
