Missouri Municipal Electric Utilities, Governor Support Power Line Project

Earlier this year, the Missouri Public Service Commission (PSC) rejected a proposal for a power line that would carry electricity generated at wind farms in Kansas to the grid in Indiana. The PSC’s decision was based, in part, on the fact that no Missouri customers would use the line or the energy it carried.

Clean Line Energy, which proposed the project, has been looking to overcome this object. It has brokered a deal with the Missouri Joint Municipal Electric Utility Commission (MJMEUC), which represents a pool of municipal utilities that pool resources to by power. MJMEUC has 67 municipal utility member and 35 are expected to take part in the deal if it is approved.

In addition, Missouri Governor Jay Nixon has expressed his support for the transmission line. In his statement, Nixon emphasized the energy savings and jobs that would be created the $500 million construction project.

The line must be approved by the Missouri PSC. It is likely to be opposed by affected landowners who campaigned against the original proposal. Official in Kansas, Illinois and Indiana have already approved the project.

What Are the Advantages of Microgrids?

This is the second in a series of posts on microgrids. See the previous post for a description of what is a microgrid.

Microgrids have several potential benefits. These include
-backup energy supply and improved reliability,
-environmental benefits,
-exploitation of local and alterative resources,
-increased energy efficiency and reduced energy consumption, and
-reduced cost.

Backup Energy Supply and Improved Reliability
Because microgrids can operate independently of the larger grid, they may be able to continue to operate when there is an outage elsewhere on the main grid.

Environmental Benefits
Microgrids are not inherently less polluting than large grids, but they may afford opportunities to manage energy resources in manners that may reduce pollution. Microgrids may be more easily able to exploit variable or small renewable sources including solar and wind energy. These smaller power supplies may also be able to address local peaks and reduce the need to ramp up production at larger, and potentially more polluting, power plants.

Exploit Local and Alternative Resources
Sometimes local energy resources are available that are not suitable for use on a large grid because they are not sufficiently powerful or reliable. Solar energy, an alternative energy source that is variable and relative low power, is an example of a resource that may be more easily exploited by a microgrid.

Reduced Cost
Microgrids might be managed in a manner to reduce costs. For instance, when prices are high during periods of peak demand, a microgrid might switch to a local power supply that is less expensive. This will also reduce the peak on the larger grid, meaning larger power plants do not have to ramp up production as much or be built to address large peaks.

60 Years of Interstate Highways

President Dwight Eisenhower signed the Federal-Aid Highway Act of 1956 on June 29 of that year. Though previous legislation had authorized interstate highways, it was under this act and the Eisenhower administration that our interstate system began in earnest.

Interstates have proven to be a safe way to travel (the fatality rate on interstates is less the rate on other routes).

Even so, the roads are showing signs of aging. Many sections are in poor condition and many bridges are structurally deficient.

Keeping up with the maintenance needs of the interstate system is an enormous task. The U.S. Department of Transportation estimates that the backlog if needed improvements totals $189 billion.

Blogger Considers Career Change


That doesn’t mean I’ll quit blogging. I’ve never made a living (or even a dime) from blogging, and it has always taken a back seat to other things. By day, I’m an employee of a state that pays the lowest wages of any state (even our legislators are starting to complain about it). Maybe I should cross the river and go back to school where I can learn to be a brewmaster, or possibly a vintner. As I recall, looking through the fog of a couple of decades, I did reasonably well in my undergraduate food processing class, so maybe I can build on that.

Consumer Group Opposes Missouri Energy Rate Reform Bill

The Midwest Energy Consumer Group (MECG) has come out in opposition of HB2689 (and its parallel in the Missouri Senate, SB1028), which would make significant changes to the way electric rates are regulated in the Missouri. The group claims that the bill would remove the voice of customers from the electric rate setting process and pave the way for regular, uncontested rate increases. The Office of Public Counsel, which officially represents customers in Missouri utility rate cases, expressed concern that the bill might limit the ability of the agency, as well as the state’s Public Service Commission, to review rate increases.

Senate Passes Energy Bill

The U.S. Senate passed its first major energy bill in a decade. The bill emphasizes development of alternative energy, natural gas, and lesser used sources such as geothermal and hydropower. It also focuses on energy efficiency and safety. The bill will need to be reconciled with the energy bill passed in the House of Representatives, which differs significantly, particularly in its approach to fossil fuels (coal, oil and natural gas). Senate leaders are confident they can work out differences with the House and develop a compromise bill that can pass both chambers latter this year.

What Is a Microgrid?

I’m seeing a lot about microgrids in utility publications and on the Internet. I thought it might be worthwhile to write something that could serve as an introduction to the subject for those who are unfamiliar with it, as well as educate myself in the process. I intend this to be the first in a series of short posts on the subject.

Let’s start with the basics. What is a microgrid?

A microgrid is a local energy grid that can disconnect from the larger grid and operate independently. It connects to the main grid at a location where the voltage of the two systems can be maintained at the same level. A switching system can manually or automatically switch the connection on or off.

Though the name “microgrid” implies something small, size is not a defining point. Microgrids are defined by
-local control, and
-functioning both connected to and disconnected from the main grid.

A Little Sewer History

The Guardian posted an article on the Great Stink of 1858 and how it prompted officials in London to improve the city’s overwhelmed system of handling storm water and wastewater. The Thames of that time was a stinking mess of sewage and a hazard to health. The sewer system devised by Joseph Bazalgette was a marvel of the age (and much of it is still in use) that moved wastewater discharges away from the populated areas around London.


You can read this very good article here. If it whets your appetite to find out more about this project, you may also want to read Dreams of Iron and Steel by Debora Cadbury. The Great Stink by Clare Clark is a fictional thriller set during this time that partly takes place in the changing sewers of London.

Bill Would Change Electric Ratemaking in Missouri

State Rep. Rocky Miller, who represents parts of Camden and Miller Counties near Osage Beach, introduced the 21st Century Grid Modernization and Security Act (HB2816). The bill would substantially change the state’s method of regulating electric utility rates. The method is modeled on processes in Illinois and would allow annual adjustments to electric rates.

Another portion of the bill substantially changes provision related to special electric rates for aluminum smelters. This is largely driven by Noranda, which operates smelter in New Madrid. It seems unlikely that lower or more flexible electric rates will save the company from plummeting aluminum prices.

With the exception of Noranda, large electricity users in Missouri have generally come out against the proposal. Some companies that have expressed opposition to the bill are Purina, Bayer, Ford, General Motors and Procter & Gamble. You can read more about this topic here.

Poop to Power Project Coming to North Carolina

Duke Energy has contracted with Carbon Cycle Energy for the construction and operation of a facility to process animal waste to produce methane gas for fuel. Waste will come from area pig and chicken farms. The gas will be piped to Duke plants as fuel in electric power generation.

North Carolina is the second largest pork producing state in the U.S. Duke is a major electric power producer, particularly in the Carolinas. Carbon Cycle is based in Colorado.


Barrel Bob Found

Barrel Bob, a character that serves as spokesman for worksite safety for the Missouri Department of Transportation (MoDOT), was found in Columbia on April 1 (no fooling) after he was stolen from his roadside station at highway construction site in Jefferson City on March 19.   The statue, constructed from used orange and reflective white barrels and cones, was previously set on fire by vandals at this location.

This statue was one of seven Barrel Bobs. Each of MoDOT’s districts has one. Bob was scheduled to make appearances at events to promote highway worksite safety beginning April 11, so the agency had resorted to building a new statue before Bob was found. You can find out more here, here and here.

Missourians Could Vote on Fuel Tax Increase

A bill (SB623) is making its way through the Missouri Senate that could increase the state fuel tax from 17 cents per gallon to 22.9 cents per gallon. The tax, if implemented, is expected to bring in $240 million annually. The bill would place a referendum on the November ballot, meaning it would have to be approved directly by voters. Before getting that far, it must complete its path through the General Assembly. The Senate is expected to pass the bill in its final vote in the first full week of April. Afterward it will be considered by the state House of Representatives, where it is not expected to be warmly received. You can read more about this here, here and here.

Significant funding for Missouri roads comes from the federal government (which has its own funding issues). MoDOT is preparing to use cash reserves to match federal grants for transportation projects (more here).

Name a Missouri Highway

An alternative to increased fuel taxes could be the auctioning of naming rights for highways. There is no estimate of how much revenue it could raise, but I’ll go out on a limb to say not enough to persuade the General Assembly to this bill. You can read the bill here. I have the impression the St. Louis Post-Dispatch reporter who covered this story must have chuckled as he typed.


Antibiotic Resistance Found in Bacteria Downstream of Wastewater Discharge

Researchers studying the biofilm in a Spanish river found antibiotic resistance genes. These genes occurred as far as 1 km (0.6 mile) downstream from the of a wastewater treatment plant. The genes provide resistance to some antibiotics commonly used in hospitals. You can find more here. In response to the issue of pharmaceutical pollution, some chemists are considering biodegradable drugs.

Superbug Found in Sewage


The U.S. Environmental Protection Agency (EPA) found carbapenem-resistant enterobacteriaceae (CRE) in the sewage at a wastewater treatment plant in Los Angeles, CA. CRE is a lethal bacteria that is resistant to most antibiotics. It was the cause of recent outbreaks in Los Angeles-area hospitals. EPA did not test the discharge from the plant for the presence of CRE, but researchers indicate that the bacteria is not destroyed or removed by typical treatment and disinfection.

More than Half of World Population Experiences Water Scarcity

Researchers at the University of Twente (reported in the Washington Post) have published a study indication that 4 billion people, more than half of the world population, experiences severe water shortages at least one month out of the year. Half a billion people experience year-round severe water shortages. Agriculture is the primary use of water. You can find a copy of the study here.

Water-Food Nexus: Better Water Management Could Lead to More Food Production


There is potential for existing agricultural lands, along with current rainwater and irrigation resources, to produce more food, potentially halving the food gap by 2050. The greatest potential is in dry areas such as the western U.S., Mexico, Australia, South Africa and China. Developing the potential of these areas depends on careful cropland water management.

Missouri Governor Proposes Funding Increase for Amtrak

The budget proposal submitted by Missouri Governor Jay Nixon included an additional $500,000 for Amtrak, for a total of $10.2 million. Amtrak claims it will need $18 million from the state to install positive train control, as mandated by Congress, on the Missouri River Runner line, with a total cost of $30 million. You can find more about this issue here.

Missouri Legislator Suggests Punt to Counties

Missouri State Representative Bryan Spencer proposed to make counties responsible for the upkeep of certain roads that are currently maintained by the state (these are generally rural, two-lane highways). This would reduce the amount of state-maintained roads by 19,000 miles. The roads in question have been state-maintained since 1952, when they were shifted away from county maintenance. To implement the proposal, the state constitution must be amended. You can find more about this proposal here and here. Most proposals to improve Missouri’s road funding problem involve raising the fuel tax.

Ameren Missouri Efficiency Program Ends

Unable to resolve differences with state regulators, Ameren Missouri has let its energy efficiency rebate program lapse. Staff of the Missouri Public Service Commission and the state’s Office of Public Counsel believed that Ameren customer overpaid the cost of the program, and opposed a three-year extension. A proposal from Kansas City Power & Light has been approved, and it might serve as a model for a compromise between the state and Ameren. You can read more about this issue here.


Bans on Texting While Driving Introduced in Missouri

Bills that would prohibit or greatly restrict texting while driving have been prefiled in the Missouri General Assembly session that started January 6: HB1542 and SB821. Currently, texting while driving is banned for drivers younger than 21 and for drivers of commercial vehicles. You can find more about these bills here.

Two proposals have been floated by Missouri state legislators. One would increase the tax on gasoline by 1.5 cents and diesel by 3.5 cents. Another would increase all fuel taxes by 2 cents. You can find more about these proposals here or here.

As an alternative to the fuel tax, SB645 would redirect 3 percent of automobile sales tax revenues from state general revenue to the road fund.


Flooded Wastewater Plants Release Sewage in St. Louis Area

Wastewater treatment plants operated by the Metropolitan Sewer District of St. Louis have released millions of gallons of sewage into rivers. The Grand Glaize and Fenton plants were inundated by the recent floods in Missouri. The two plants, which combined treat and average of 20 million gallons of wastewater per day, discharge into the Meramec River.

White House Announces Water Strategy


The White House announced a strategy to the sustainability of U.S. water supplies and systems. The cynic in me suspects that these strategies, programs, and actions were things that were mostly in the works anyway, but someone cobbled them together into a seemingly unified program (you can can get the details here). Even so, we need to take a serious look at our water resources, policies and practices. Good policy that addresses today’s water situation is needed, but sustainable water for our nation will come when we have a culture that values water for the many roles it plays in our environment, industry, health, recreation and almost every other aspect of human life.
