CMEC led the forma- tion of the Center for American Rural Energy (CARE), a consortium dedicated to demonstrating and evaluating innovative energy technologies and approaches. CARE is designated as a Center of Excellence for Energy Inno- vation by NRECA. • Eastern Illinois University, a founding partner along with CMEC in CARE, provided student research. The student team identified data sources and determined that a large portion of quarries are located in rural areas. The team contributors were: Tajdar Ahmed, Tanmay Pant, and Ayaz Khamisani. • Advanced Energy, a North Carolina-based nonprofit with a strong industrial energy efficiency program, provided guidance and advice on energy usage data and on the calculations used to estimate energy savings.

Contributors End Notes Stone. Sam Adair, CMEC's manager of member services, made personal visits to the quarry. So, when Charleston Stone approached CMEC to talk about the electric service they would need for their new crusher, the discussion was built on an established relationship. CMEC worked with Charleston Stone to figure out how it could be most helpful to the conversion project. The co-op then developed a plan for expanded electric service and determined that it would be advantageous for Charleston Stone to purchase the new transformer and install it on the mobile crusher station. CMEC ran an upgraded, 7,200-volt line to a primary metering pole on each side of the river. A switch cabinet was installed at the base of the pole (see Figure 10). CMEC decided to pursue a REDLG loan that, if successful, could provide $400,000 in interest free financing to Charles- ton Stone. REDLG is a competitive program from the Rural Utility Service of the U.S. Department of Agriculture. CMEC has had success with REDLG before, thanks to assis- tance from its G&T;, Prairie Power. Prairie Power had a staff person for many years that assisted distribution co-ops in preparing and submitting REDLG program applications. 20 This staff person had left Prairie Power, but CMEC hired him on contract. CMEC guaranteed repayment to RUS, which was an important factor in the REDLG application being successful. Tarble was pleased, commenting that, "the REDLG loan was a big help." The $400,000 zero-interest loan made the project more feasible. Patrick Keegan is the founder of Collaborative Efficiency, an energy services firm specializing in support for all phases of energy efficiency program development at electric cooper- atives and municipal utilities. Keegan has been involved in energy efficiency programs since the 1980s. He has worked on solar energy and demand response. He's the author or co-author of more than 20 reports for co-ops about demand side energy technologies and programs. He has often been a speaker at national co-op conferences and has recently focused on electric vehicles, financing and beneficial electrification.
