Natural Gas Power Plant Approval Case Gets Started
The first hearing at the Michigan Public Service Commission (MPSC) regarding the application of Consumers Energy to build a 700 MW natural gas-fired power plant (Case U-17429) occurred August 19. Twelve intervenors were granted party status: the Michigan Energy Innovation Business Council; Energy Michigan; Attorney General for the State of Michigan; Association of Businesses Advocating Tariff Equity (ABATE); Midland Cogeneration Venture Limited Partnership; Renaissance Power LLC; New Covert Generating Company LLC; Interstate Gas Supply, Inc.; First Energy Solutions Corp.; Michigan State Utility Workers Council; Sierra Club; National Resources Defense Fund; and Michigan of Environmental Council. Potential issues to be raised by the interveners include the assumptions in the filed Integrated Resource Plan on:
- alternative and renewable energy generation availability and costs;
- the limitations of the customer choice program;
- the closure of seven coal plants with a total capacity of 950 MW; and
- the impact of energy optimization and conservation on future load demand.
ABATE has indicated it will be filing a Motion for Summary Judgment seeking the dismissal of the application, asserting that Consumers Energy has not properly shown a need for a new power plant. Assuming the case is not dismissed, a schedule has been set calling for cross examination of witnesses the second week of December, and a decision by the MPSC on or before the 8th of April, the statutory deadline for a decision on the Certificate of Necessity request.

(naval architects and marine engineers out of Seattle) presented the latest design and deployment plans for the Pelastar floating wind turbine system at the Michigan Alternative and Renewable Energy Center in Muskegon.
Emphasizing the opportunity to locate near load demand, Nordstrom explained the system avoids the difficulties of offshore construction and assembly by allowing the floating platform to be build dockside, with tower, nacelle and blades attached by a land-based crane. The entire assembly is then floated to its location and tethered to the lake or sea bed. The first 6 MW demonstration project, supported by Alstom Wind, NREL, BP, Rolls-Royce, Shell, Caterpillar, and others is targeted for offshore at Cornwall, England, in late 2015. Cost of energy estimates for first generation offshore wind farms is $0.170 per kWh, and below $0.13 in the second generation design for 10 MW wind turbines. The floating platform must be in at least 50m of water depth, and can be deployed at up to 500m depth.
Cellulosic Ethanol Plant Loses Partner
Mascoma Corporation has lost a major funding source in its efforts to build a 20 million gallon ethanol plant in Kinross. Valero Energy Crop has pulled its $50 million investment in the project. An IPO for Mascoma that would have raised $100 million has been placed on hold. The company has stated it will not proceed with the project until all funding is secured. The total cost for the facility, which has $120 million in public funding pledged, is $232 million.
Anaerobic Digester Opens at MSU
Michigan State University has commissioned an anaerobic digester to create energy for its East Lansing campus. The digester will utilize about 17,000 tons of organic waste to generate 2.8 million kilowatt hours of electricity per year. The organic material used by the system includes cow manure, food waste from several campus dining halls; fruit and vegetable waste from the Meijer Distribution Center in Lansing; and fat, oils and grease from local restaurants. It will take 20 to 30 days to digest the material in the 450,000 gallon tanks. Total cost of the project was about $5 million, and is expected to pay for itself in less than 15 years. MSU is also involved in a similar project in Costa Rica. that will provide power to a local village.

University of Michigan has received a National Science Foundation four-year, $2 Million grant to determine what combinations of algae make the most efficient fuel source Lights Out at Detroit’s Municipal Utility? The Detroit Public Lighting Department (PLD) currently serves 115 customers, including: Detroit Public Schools; Joe Louis Arena; Cobo Hall; the Detroit Institute of Arts; Wayne State University; McNamara Building Federal Building; and the city’s traffic signal system (almost 1300 intersections).
The Detroit Emergency Manager recently notified DTE Energy Company that PLD will be winding down its electricity distribution and transmission services and requested that DTE provide service to PLD’s customers. The switchover will take five to seven years, as DTE will replace the PLD grid over time. How DTE will recover the costs of the transfer and upgrades has become an issue to be decided by the MPSC in Case No. U-17427. See www.tinyurl.com/mpsc-pld
The Incredible Shrinking Renewable Energy Surcharge
Consumers Energy is asking to eliminate its authorized renewable energy surcharge beginning in July 2014. The residential charge under PA 295, was initially pegged at $2.50/month, then lowered twice to its current $0.52/month charge. Meanwhile DTE Energy has asked the Michigan Public Service Commission to lower its monthly residential renewable energy surcharge from $3/month to $0.43/month. Commercial and industrial surcharge reductions are also being requested by both utilities.
Made in Michigan Microgrid Under Development
In 2006, NextEnergy in Detroit was contracted by TARDEC and the Defense Logistics Agency to develop equipment to provide US-grid quality power in remote locations using renewable and conventional power sources. Although the project was successfully tested, it was too large and too heavy to be deployed in the field, as it required a 20-foot long container for shipping. But the concept of an intelligent management for remote power systems had been proven and the Tactical Modular Mobile Microgrid was born. TM3 Systems of Royal Oak is now working to reduce the size and commercialize the concept. The building blocks for its system are four-foot cubes capable of managing up to 360 kW of generation. By metering and controlling both inputs (generators, solar panels, and battery banks), and outputs (downstream loads), this “microgrid,” is more reliable, efficient, configurable, and controllable than a typical remote power system. It can use dissimilar power sources (fossil fuel generators, solar arrays, and batteries) to reduce fuel consumption while supplying uninterrupted power to critical assets in remote location.
