Avoid Downtime in Methane Digesters for Dairy Operations

Share this article:

The onset of “LCFS” Low Carbon Fuel Credits spiked demand for power created from the Dairy Industry in the form of Methane Digester Systems as a Distributed Energy Resource, or DER. Low Carbon Energy Credits, which are derived by having a low carbon impact in the production of the power created, can be purchased by large Power Conglomerates to offset the high carbon impact is systems like drilling or fracking for natural gas. Dairy Farm Methane Digester Systems in operation all over the country now can not only produce valuable resource at a premium, but also satisfy demand for these High-Value LCFS Credits on the West Coast. As the trend continues for State, Municipal, and general Government Mandates, and incentives for a cleaner, carbon neutral supply, these Digester farms, Solar, and Wind Farms will likely see an increase in price demand per kW.

High Dollar Digester Natural Gas to West Coast Instead of Electricity

As Methane Digester production was introduced a couple of decades ago, it was a process framed at converting the by-product of Dairy Farms manure supply into a usable form of gas that could be burned in a very local gas generator and alternator producing power which would assist in running operations at the farm, and if efficient enough, sell some of the power back to the utility. The incentive on the value of that power was minimal other than the direct benefits of creating a kW out of something you would otherwise spread on a field. As the digester systems have become more evolved and efficient the natural gas by-product of the process can be directly loaded into a distribution truck, taken, and contributed into a pipeline, and shipped to a western state. A Dairy and Digester Farm in WI can now efficiently sell LCFS creditable power units to a larger gas and petroleum supplier to offset otherwise high carbon production. This is why there is a demand premium put on the digester produced gas.

Points of Interconnection POI for Methane Digesters

Whereas the Point of Interconnection of a Solar Grid may consist of connecting to a substation at various voltages, integrating it’s power capacity at that point in the power grid, then having the local utility manage the distribution of that power. The new ability for natural gas to be produced in states far away by a methane digester and trucked over to a distribution pipeline and connected into a regional pipeline for distribution, opens up a whole opportunity for interconnected clean power. The space needed to operate facilities such as widespread Dairy Operations, the requirement for feed stock, and the proper environment for the cows requires vast and variable resources. This gives a very different look to the future of Methane Digestor processing and the Dairy Industry of the future. 

Process Interruptions and Voltage Stabilization in Methane Digester Processes

For proper execution of the digester process, the voltage supporting the processing equipment, pumps, boards, and equipment must have good stable voltage. This really has nothing to do with the output product of the digester, but what electrical supply is available for use at the site. Usually this is a rural farm environment without the most reliable voltage. Because of the relationship between a change in voltage and changes in amperage used by equipment. Any drop or sag in voltage will derive a direct and offsetting spike in amperage. Vice versa, a surge in voltage will provide a direct offsetting sag in amperage used by the equipment it is supporting. All of this means that the equipment using the imperfect voltage at these sites gets a pretty harsh environment to operate.

Solutions to Methane Digester Process Interruptions

The maintenance budget to operate a Methane Digester is a direct influence on its output and success. If control boards to the operating systems are constantly burning out due to stray voltage problems, this is easily correctible. If a shut down is directly attributed to a sag or interruption in power, this also is easily correctible. Many digester farms have backup generator systems to make sure that the processes do not ever stop. This does not, however, correct the ever-variable voltages that happen in an operation with pumps and large equipment cycling on and off. Voltage Stabilization and Correction Systems can be installed at point of controls, or around the entire process electrical supply to thwart off these damaging effects.

Using Medium Voltage (MV) with Power Distribution for Industry provides an efficient delivery of High Capacity Power to Manufacturing Facility and Industrial Production Floors. A higher voltage provides a more “efficient” path for “AC Current” to travel to equipment. Large Motors and high inrush starter loads require much more Startup Current, medium voltage power distribution within a plant will provide an efficient capacity of Amperage for this high demand equipment. If production equipment in a Plant operates at lower voltage (LV), the delivery mechanism of higher voltage, closer to the equipment seeking the higher amperage, makes for more capacity available to the loads. This is achieved by the installation of step down function transformers, allowing the medium voltage (MV) to deliver higher capacity amperage “near” the loads. Then step down voltage at or near the equipment to the usable voltage. Benefits of Medium Voltage in a Facility -Higher Amperage Capacity delivered closer to Equipment Seeking Current (Amps). -Less “Current” loss during distribution through plant to various loads. -Lower “Pipe and Wire” costs as higher voltage requires smaller wire size to transmit. -More reliability in overall plant equipment: ie. Affects of power anomalies from lower voltage, sags, surges, failure of Machine Equipment Components. Disadvantages of Medium Voltage in a Facility -Higher cost to Utility for setup -Specialized Maintenance at higher voltage levels -Potential first costs higher for substation and distribution equipment up front, but lower cost of ownership over time. Low Voltage for Industrial Loads Low voltage distribution in a Plant can be installed successfully with a very constant load profile and demand. If there is larger equipment such as motors and processing that cycle on and off with large inrush current demand, this will affect the other areas of the Plant. These “surges” in demand for Current in these high demand inrush devices, can starve or pull down overall voltage in the other areas in the plant electrical distribution, or the entire plant. This will cause Power Supply failures in other equipment which seeks a constant voltage, or will burn components of other equipment due to variable voltage events. Over time this greatly affects a Plant’s Maintenance budget. Benefits of Low Voltage in a Facility -More Familiar Installation and Voltages for most Electrical Contractors. -Immediately available equipment, shorter lead times. -Simpler design and operation of electrical distribution and Electrical One Line. -Less step-down transformers within Facility and Electrical One Line Disadvantages of Low Voltage in a Facility -Exposed to more “Load” created anomalies that may affect other equipment -Limited amperage “Choke Points” for distribution and installation of larger equipment -Current loss from LV distribution through plant. -Susceptible to Inrush Current affect on immediate area or entire facility. -Higher “Pipe and Wire” costs as lower voltage requires higher amperage and larger wiring. Description and Uses of Low (LV) and Medium Voltages (MV) Low Voltage: 1kV - 15kV Typical City Use Power Grid Activities -Residential Use: (120v, 240v) -Commercial Building Use: (120/240v Single/Three Phase, 480v Three Phase) -Manufacturing and Industry: (480v Three Phase) -Localized Utility Distribution: Transformer to Load Medium Voltage: 13.8kV-34.5kV -High Density Data Center Uses -Large Manufacturing, Semiconductor -Motors, Compressors, Large Use Industrial Process -Electrical Utility Distribution, Long and Short Line distances High Voltage: 35kV and larger, 138kV -Long Transmission Lines Substation supply lines from Power Utility Sources -Industrial Processing Facilities, Steel, Mining. -Large transit requirements such as Railways and Commuter trains See your Voltage Correction Specialist to discuss Medium Voltage Power Distribution Options and Corrective Measures for your Facility Power Issues.

High Density AI compute performance chips like Nvidia Geoforce and now Blackwell B200 chips are requiring up to 300 watt, 400 watt, and 1200 watts. New rounds of chip development are considering up to 3000 watts of power per chip and requiring MEP Engineering design to consider bringing higher voltage closer to the Rack Loads. Why Medium Voltage UPS Systems Higher voltage carried over distances is more efficient than lower voltages carried over the same distance. Medium Voltage (13.8kV, 34.5kV) requires lower current (amps) to achieve the same capacities as low voltage (480v/208v), which exponentially changes the amount of power you can move from Point A to Point B, point B being the Rack loads. 480V Power Distribution for Data Centers In a legacy data center, medium voltage would be delivered to a substation or switchboard on-site. Transformers then step down medium voltage to 480V, which is widely used in data centers for the last 35 years. The typical legacy larger data center delivers 480 volts through the input switchgear, Uninterruptible Power System (UPS) via it’s Maintenance Bypass Switchboard route, and on to a Floor Power Distribution Unit (PDU). At the PDU, the load is stepped down via a internal PDU Transformer to usable 120/208V and 120/240V, which panels of breakers, or sub-feed breakers on the PDU support the actual breakers for servers. Low Voltage UPS Systems are limited to certain capacities to accumulate kW output for larger 2500kW or 5000kVA capacities. See Diagram 1.1
