Irrigation workshop introduces water apps for growers

Western teamed up with Nebraska Public Power District  You are leaving WAPA.gov. (NPPD), the Department of Agriculture’s (USDA) Rural Energy for America Program (REAP), Clean Energy Ambassadors You are leaving WAPA.gov. and Central Platte Natural Resource District You are leaving WAPA.gov. last November to present an irrigation workshop for agriculture energy customers of NPPD members.

REAP Irrigation Energy Cost Savings: From Testing Your Pumps to Financing and Completing the Project offered an overview of load management and efficiency opportunities; the REAP program, including eligible projects and application guidelines; and a case study on a solar pumping system. Participants learned about REAP success stories and utility incentives, met equipment vendors and watched NPPD Energy Consultant Ronald Rose, Kelley Messenger of the USDA and Equipment Loan Manager Gary Hoffmann demonstrate pump testing methods.

Troy Ingram, of the University of Nebraska, Lincoln, (UNL) introduced two new mobile apps the UNL Extension program You are leaving WAPA.gov. developed to help growers manage their irrigation systems. Utilities and their agriculture customers can benefit from these easy-to-use tools, even if they were unable to attend the workshop.

Pricing water
The IrrigateCost app You are leaving WAPA.gov. models center-pivot and gated pipe irrigation systems and the most commonly used energy sources. Using information such as acres irrigated, pumping lift, system PSI, pump and pivot life, and inches applied, the app computes total irrigation cost, along with the total cost of owning and operating a system. It also breaks down costs by irrigation well, pump, gear head, pump base, diesel engine and tank and system and calculates per-acre annual cost and per-acre-inch annual cost.

Growers make a number of management decisions based on the annualized costs of owning and operating an irrigation system, starting with whether or not to develop land for irrigation. For a system to be economically feasible, the net income from increased yields due to irrigation development must exceed the additional costs of owning and operating the system over its expected life. Once development is underway, the app can help determine design choices, including selection of energy source for pumping water, the type of distribution system, and so on. Other uses for the app include:

  • Calculating a fair crop-share rental agreement
  • Knowing what to charge for watering a portion of a neighbor’s field
  • Estimating costs to pump an acre-inch of water to help you determine how many additional bushels of a crop are needed by applying one more inch of water at the end of the irrigation season

The app is available through most phone carriers’ app stores. iPod and iPad users can get IrrigateCost from the Apple iTunes store You are leaving WAPA.gov. for $1.99. In The Google App Store You are leaving WAPA.gov. offers a version of the app for Android users, also $1.99.

Pricing efficiency
IrrigatePump You are leaving WAPA.gov. helps to calculate the efficiency of a pumping plant and to determine the potential savings from upgrading the system.

Whether a pumping plant uses diesel, electricity, gasoline, natural gas or propane, chances are it is using 25 percent more energy than expected by the Nebraska Pumping Plant Performance Criteria You are leaving WAPA.gov. (NPC). A pumping plant meeting the criteria delivers the expected amount of useful work, measured as water horsepower hours, for the amount of energy consumed. The NPC is based on field tests of pumping plants, lab tests of engines and manufacturer data on three-phase electric motors.

The user enters six numbers related to pumping lift, pressure at the discharge, acre-inches of water pumped, fuel price and total fuel used. The app then calculates a pumping plant performance rating, provides an estimated cost to bring the pumping plant up to standard and the number of years for payback on the investment at various interest rates.

Both apps provide anonymous results that users can capture and email to their own devices. The cost of IrrigatePump is $1.99 through Apple, Google or phone carriers.

Ingram noted that these apps are new and have not been through a full growing season yet, but he has used them and other agriculture apps on his own farm. Crop Water, an app UNL developed for scheduling irrigation—specifically for Nebraska soils—has been particularly helpful, he added.

Farming goes high-tech
There are now apps for almost every aspect of farming and ranching, from monitoring invasive species in your area to logging machinery maintenance, and most are free or inexpensive. Utilities might consider giving agriculture customers apps that are related to energy and water management like IrrigateCost and IrrigatePump. Apps could be great small incentives and customer relationship builders.

Just remember that not all apps are created equal. Croplife magazine You are leaving WAPA.gov. suggests doing a little homework before selecting an agriculture app. Or, better yet, contact your local university extension service to find out what they recommend or offer. Farming is a tough job, and growers will appreciate anything their utilities can do to help them operate more efficiently and effectively.

[Editor’s note: Apps aren’t the only thing you can offer your ag customers. Contact Energy Services if your utility is interested in sponsoring an irrigation efficiency workshop like the one NPPD presented in Grand Island.]

DOE announces funding, partnership to promote electric vehicles

To accelerate the adoption of electric vehicles, the Department of Energy has made available $5 million in new funding for community-based efforts to build electric vehicle (EV) infrastructure and charging stations. The initiative also includes a partnership with Google, Inc., and more than 80 EV stakeholders to help consumers find charging stations nationwide.

Energy Secretary Steven Chu and Transportation Secretary Ray LaHood announced the initiative on a conference call recently with Colorado Governor John Hickenlooper, Tucson Mayor Bob Walkup and St. Paul Mayor Christopher Coleman – leaders of three of the nation’s nearly 100 Clean Cities Coalitions.

“The Department of Energy’s Clean Cities initiative is bringing together local governments and industry to demonstrate the benefits of advanced technology vehicles and help communities use less oil and gasoline to power their vehicles,” said Secretary Chu.

The funding and the partnership are the Obama Administration’s latest steps in its broader push to reduce U.S. oil imports by one-third by 2025.  Read more.
