1. What are possible definitions of "reliability" that have been used or proposed for use by policy makers? What studies exist regarding the economic and environmental benefits of baseline or "additional" reliability?

Energy Forum Comment


For electric companies providing retail electric service, "reliability" is often measured or discussed in terms of System Average Interruption Duration Index ("SAIDI")  and System Average Interruption Frequency Index ("SAIFI")measures that speak to frequency and duration of customer impact. From a transmission perspective, 100 percent compliance with NERC standards also constitutes "reliability."

In addition, The North American Electric Reliability Corporation ("NERC") provides an independent view of the 10 year reliability outlook for the North American Bulk Power System. The most recent assessment can be found at http://www.nerc.com/files/2012_LTRA_FINAL.pdf.

Lastly, the SGS benchmarking study referenced in question two has been conducted since 1995 and is the largest independent benchmarking forum for electric transmission reliability. It provides a comprehensive reliability assessment at an operating company level.

The electric utility industry defines "reliability" as maintaining thermal, voltage and stability limits within the system. MISO has three types of studies that are currently applicable to transmission planning in its footprint, which evaluate reliability, economic, and environmental benefits across the entire footprint.  These studies include the Multi-Value Project (MVP) study, Northern Area Study (NAS), and Market Efficiency Project (MEP) study.

The NAS, currently underway, is evaluating a proposed electrical connection between Lower Michigan and the Upper Peninsula (U.P.) and will measure the reliability, economic and environmental benefits resulting from this connection.  The reliability benefits are associated with the contingencies of the 345 kV, 138 kV, and 69 kV transmission networks in Lower Michigan and the U.P.  Potential economic benefits are related to lowering Michigan's Locational Marginal Pricing (LMP) costs, reducing losses, reducing congestion, increasing import/export capability and increasing the opportunity for commerce in Lower Michigan and the U.P.  Potential environmental benefits include access to the lower cost renewable resources from the western region of MISO's footprint and the mitigation of reliability issues associated with generator retirements and new generator interconnection.

Wolverine's preliminary analysis shows that Michigan's LMP costs are significantly higher than our neighboring states and the greater Midwest.  Lower Michigan's transmission infrastructure is essentially a radial system ending in Gaylord with no connection to the U.P. and greater Midwest, which exacerbates this extra LMP cost or "tax" on Michigan's electric customers.  NAS evaluation elements do not contemplate this tax on Michigan customers.  Wolverine encourages the Michigan Public Service Commission and the Administration to collaborate with MISO and the utility industry to complete a detailed analysis of this additional tax on Michigan customers to assure that the scope of all MISO studies includes the impact of this tax in cost/benefit analyses. 

Michigan's Renewable Portfolio Standard should be expanded to allow access to these lower cost renewable resources, and Michigan's transmission infrastructure must be expanded from Gaylord north to the greater Midwest region to allow for delivery of these lower cost renewable resources to Michigan customers. - Kim, Wolverine Power Supply Cooperative, Inc.


1. Electric reliability is composed of adequacy and security of supply and delivery. Adequacy refers to having enough, whereas security reflects the ability of the system to withstand disturbances. Both of these drivers of reliability apply to the supply, or generation, of electricity as well as its delivery to customers through transmission and distribution systems

2. Electric reliability is critical to our national safety, security, health, and economic prosperity. Reliability is an economic "public good", with enormous (and immeasurable) societal benefits. - Joint response from DTE Energy, Consumers Energy, and MEGA

Dear Governor Snyder,

As a citizen who must take some responsibility for our environment, I have made attempts to better understand fracking. At best, it seems to be a controversial method for extracting natural gas deep within the earth. The horror stories of what can and has gone wrong in the process is reason for much concern.

I am heartened by the fact that you have partnered with the University of Michigan to better study each and every aspect of this issue. Since results will not be out before 2014, I think it is important to stop current fracking operations. We simply don't know....and until we do, we must pause. Corporate interests in 2013 should not trump the potential for negative long-term consequences. We need data --- objective, valid, reliable data......and until then, I urge you to do what it takes to discontinue fracking operations in Michigan.

I join you in wanting to ensure Michigan's future. A future with no regrets.

The National Institute for Science, Law & Public Policy report that Smart Grid Funding is Misspent on Obsolete Technologies. - Donald, Prof. Emeritus, MSU 02/11/2013
Many fellow citizens who know the truth about "fracking" are very concerned that billions of dollars of profit from the oil/gas industry are being used to misinform the public about the poisoning of our Michigan water 20% of the world's drinking quality water. The industry admits that getting to the shale, requires 2-3 miles of drilling,requiring 500-900 million gallons of fresh water drawn from our precious water table and then add "only" 1/2%, 250-450,000 gallons, of very toxic chemicals and must be refracked every 2 years. According to recycling guidelines, we are told not to put in hand lotion and tooth paste containers, because they contain low levels of toxic preservatives that contaminate our water. Fracking would be very poor stewardship of what is already a scarce essential resource required to maintain life - clean water. We cannot allow the rush for technology to pollute our state water for the sale of cheap gas to China. We must protect our drinking water, livestock and produce. - Carol, Citizen 02/02/2013
