Combined Heat and Power (CHP)
More states are undertaking new approaches to utility planning that prioritize clean, distributed energy resources, but few are considering combined heat and power (CHP) for meeting the demands of the modern grid. In many ways, CHP provides exactly what they need.
Why utilities are investing in this technology as a way to boost resiliency and reduce consumer costs
What if there was a technology your utility could deploy today that was cheaper and cleaner than most existing power generation, that boosted system resiliency and reliability, and was twice as efficient? Would you want them to use it?
Combined heat and power (CHP) systems, also known as cogeneration, generate electricity and useful thermal energy in a single, integrated system. Heat that is normally wasted in conventional power generation is recovered as useful energy, which avoids the losses that would otherwise occur from separate generation of heat and power. While the conventional method of producing usable heat and power separately has a typical combined efficiency of 45 percent, CHP systems can operate at efficiencies of 60–80 percent or more.
ACEEE State Scorecard: Massachusetts Edges Out California as Most Energy-Efficient State, Maryland Among Most Improved
Top 10 States Ranked in Energy Efficiency Scorecard: MA, CA, VT, RI, OR, CT, MD, WA, NY … With MN and IL Tied for 10th; Five Most Improved States: MD, IL, DC, CA, and TX; and Five States in Most Need of Improvement: MS, LA, SD, WY, and ND.
October marks the release of the 9th edition of ACEEE’s State Energy Efficiency Scorecard, and we’re convinced it’s the best one yet. That’s because every year we refine our methodology, getting better and more specific data from states and adjusting our scoring criteria to reflect the changing landscape of energy efficiency. This year, we are making a few big changes, but you’ll still recognize the State Scorecard you’ve come to know.
Emissions reductions from combined heat and power (CHP) can help states comply with their obligations under EPA’s proposed Clean Power Plan. ACEEE has released a step-by-step guide to help states do just that. ACEEE’s new CHP template is intended to help states understand how to document and claim emissions reductions that result from CHP measures in their state plans.
Here at ACEEE we are big fans of combined heat and power (CHP). It’s energy efficient, it helps with resiliency, and it could be a key strategy for complying with carbon pollution reduction requirements.
ACEEE’s State Energy Efficiency Scorecard was released last month. You may have seen the rankings, but did you know that combined heat and power (CHP) has its own chapter? We’ve been publishing the Scorecard since 2007. Each year, we’ve seen the policy landscape change, and we’ve refined the metrics to quantify state progress in each policy area to make sure they keep pace with current trends. The CHP chapter is no exception.
Massachusetts Tops California as Most Energy-Efficient State, while Arkansas, D.C., Kentucky, and Wisconsin are Most Improved
Top 10 States are MA, CA, RI, OR, VT, CT, NY, WA, MD, and MN; 5 States Most in Need of Improvement are ND, WY, SD, MS, and AK
Washington, D.C.—Governors and lawmakers in state capitals across the nation continue to take major steps to lower energy costs, reduce pollution, and save consumers money by increasing their states’ energy efficiency, according to the findings of the 8th edition of the State Energy Efficiency Scorecard released today by the American Council for an Energy-Efficient Economy (ACEEE).
We spend a lot of time here at ACEEE with numbers. We calculate energy savings, efficiency investments, and jobs. Even with all this data at our fingertips, though, I’m always most curious to see the numbers we produce every fall in the State Energy Efficiency Scorecard. This will be the eighth year we’ve ranked states on their adoption of policies that encourage energy efficiency, and while some results are easy to predict, there are always a few surprises.
