Irrigation workshop introduces water apps for growers

Western teamed up with Nebraska Public Power District  Redirecting to a non-government site (NPPD), the Department of Agriculture’s (USDA) Rural Energy for America Program (REAP), Clean Energy Ambassadors  Redirecting to a non-government site and Central Platte Natural Resource District  Redirecting to a non-government site 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  Redirecting to a non-government site 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  Redirecting to a non-government site 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  Redirecting to a non-government site for $1.99. In The Google App Store  Redirecting to a non-government site offers a version of the app for Android users, also $1.99.

Pricing efficiency
IrrigatePump  Redirecting to a non-government site 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  Redirecting to a non-government site (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  Redirecting to a non-government site 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.]

Wind, solar acquisitions make sense for Lincoln Electric System

Staring down a future of potential environmental regulations and uncertain production tax credits, Lincoln Electric System Redirecting to a non-government site (LES) in Lincoln, Nebraska, is surging forward on “greening up” its power portfolio.

The municipal utility closed 2014 with a power purchase agreement to add 173 megawatts (MW) of wind energy and 5 MW of solar energy to its power supply resource portfolio by 2016. The move will reduce coal resources from 43 percent of LES’s installed nameplate capacity to 34 percent.

This latest acquisition is not part of a predetermined goal, but simply a good business decision, observed LES Administrator and CEO Kevin Wailes. “When viewed as a package, our wind and solar contracts are expected to save LES customer-owners approximately $429 million over the next 25 years,” he pointed out when announcing the agreements.

LES Communications Manager Kelley Porter added, “Responding to customer input and being good environmental stewards is part of doing business as a public power utility.”

Wind brings development
The wind additions, spread across two contracts with developer Invenergy Redirecting to a non-government site, involve the 73-MW Prairie Breeze II Wind Energy Center in northeastern Nebraska and 100-MW Buckeye Wind Energy Center in north-central Kansas. The projects will bring LES’ total wind portfolio to 304 MW, and increase the utility’s renewable generation portfolio to the equivalent of 48 percent of LES’ retail energy.

Prairie Breeze II is an expansion of Invenergy’s first Nebraska wind farm, which began operation in May 2014. The developer expects to complete Prairie Breeze II by the end of 2015. The project will create an estimated 90 jobs during the construction phase, and is expected to require seven permanent full-time employees to operate and maintain the 41 turbines.

Let the sun shine
Cost savings from the wind agreements will help supplement customer participation in LES’s new SunShares community solar program. LES launched the program in partnership with its customers to bring a community solar project to the Lincoln area. The 5-MW solar array—the largest in the state—will provide the utility with valuable solar experience.

The solar contract was in response to an LES survey indicating customers were willing to support more local solar energy. About 44 residential customers take advantage of LES’s renewable generation program and net-metering policy, but the city has a lot of older neighborhoods with large trees, Porter noted. “The solar project offers an affordable alternative for customers who would like to be involved with solar but don’t have the ideal circumstances,” she said.

The enthusiastic response to the solar farm indicates that a good many LES customers fall in that category. The program launched on Aug. 1, 2014. “We held a press conference to announce it on Aug. 2, and 1,200 customers had signed up by the time we signed the agreement,” Porter recalled.

Marketing of the solar installation was not limited to the news conference. LES enlisted the same local environmental groups and citizens who had pushed for the project to speak to community groups. Promotion also included a two-month blitz of social media, radio interviews, posters, newspaper ads and bill stuffers.

Future builds on past
Now that LES has had a chance to gauge the real interest in the solar project, the promotion has entered its second phase. “The site is highly visible from Interstate 80, so the community can watch as the project is constructed and feel like a part of it,” Porter said.

The solar farm will significantly increase the amount of solar power in the municipal utility’s resource mix. In addition to the customer rooftop systems, LES recently added 50 kilowatts of solar energy through a rooftop solar array on one of its service buildings.

LES prides itself on a history of aggressively building its renewable energy portfolio, starting with two utility-owned and customer-financed wind turbines in 1998. The new solar program further diversifies an energy supply that includes 4.8 MW generated by the Bluff Road Landfill waste-to-energy facility, commissioned in 2013.

The new wind and solar contracts are only the latest example of the municipal utility’s move toward greater sustainability. In a changing industry, this openness to innovation has helped LES control costs, ensure reliable power delivery and keep rates affordable for its customer-owners. As Wailes explained, “We make decisions to best reflect the values of our community.”

Upcoming deadlines

Catching up on industry news

Welcome to 2015, a time to start fresh and explore new territory. Whether that means launching or updating efficiency programs, seeking out more education or bringing attention to your successes, here are some news items to help you on your way.

Efficiency increases in 2014
Watch for new appliance efficiency standards from the Department of Energy. In 2014, DOE issued a total of 10 new or updated standards, including commercial refrigeration, electric motors, external power supplies, furnace fans, metal halide lamps, wall-unit air conditioners and walk-in coolers. Altogether, these 10 standards will help reduce carbon dioxide emissions by more than 435 million metric tons and save American families and businesses $78 billion in electricity bills through 2030.

Regulations matter
According to the Edison Foundation Institute for Electric Innovation (IEI), fixed-cost recovery mechanisms play a significant role in supporting electric efficiency. The 2014 IEI report Redirecting to a non-government site found that investment in energy efficiency depends on state policies that allow utilities to pursue efficiency as a sustainable business as well as state mandates for energy efficiency.

Fixed-cost recovery mechanisms, such as decoupling and lost revenue adjustment, help a utility recover the marginal revenue associated with fixed operating costs. Utilities appear to be more willing to invest in programs to reduce energy use if state regulations allow them to recoup their losses.

The American Council for an Energy Efficient Economy (ACEEE) bolsters the IEI report, with nine of the top 10 states on its 2014 State Energy Efficiency Scorecard Redirecting to a non-government site having a fixed-cost recovery mechanism.

Webinar describes utility trends in adopting community solar programs

SEPAWAPAFeb. 4, 2015
2 p.m. MST

Western Area Power Administration and the Solar Electric Power Association Redirecting to a non-government site (SEPA) are teaming up to present a webinar that explores the utility’s role in the community solar market segment on Feb. 4, 2015, from 2:00 to 3:30 p.m. Mountain Standard Time.

The community solar model offers utilities an innovative way to engage with customers who want to invest in renewable energy but, for a variety of rea­sons, may not be able to install rooftop arrays. Community solar programs offer utility customers the opportunity to buy “shares” in a centralized project, often called a solar farm or solar garden. Utilities around the nation are using these programs to meet growing consumer interest in supporting renewable energy.

SEPA has been tracking the spread of these proj­ects across the United States since early 2012. With nearly 60 active programs, utilities represent 87 percent of all com­munity solar programs now online.

Utility Trends in Adopting Community Solar Models Redirecting to a non-government site will open with Becky Campbell, SEPA Senior Manager of Research and Advisory Services, defining community solar and explaining why some utilities see it as a valuable customer engagement tool. Using case studies of actual utility programs to support the discussion, she will highlight nationwide utility trends in program adoption.

Presentations will cover additional data, including actual participation statistics that SEPA collected through a 2014 survey of utility program administrators. Atttendees will also learn about design characteristics common to some of the nation’s most successful community solar programs.

Randy Manion, manager of Western’s Renewable Resource Program, is urging Western customers to attend the webinar to learn more about this strategy for adding solar power to utility resource portfolios. “Several of our customers have already launched community solar programs, including Colorado Springs Utilities, Poudre Valley Rural Electric Association and Kit Carson Electric Cooperative,” he noted. “Their members have been enthusiastic, and many projects are fully subscribed before construction is complete.”

There is no cost to attend the webinar, but registration is required.

Gunnison County Electric Association Redirecting to a non-government site (GCEA) has joined the list of Western customers who have borrowed a weather station from our Equipment Loan Program to teach students and their parents about the weather in their community.

Equipment Loan Manager Gary Hoffmann traveled to Lake City, Colorado, in November to deliver the unit and help technicians from GCEA install it on a theater. The station collects data on temperature, humidity, wind speed, rainfall, solar energy and more. The information is available on the Weather Underground website Redirecting to a non-government site .

Lake City Community School students, teachers and district officials attended an unveiling event for the weather station organized by Philip Virden, the theater owner. Teachers plan to incorporate the weather station data into science lesson plans. The data will help the next generation of consumers gain a better understanding of how the weather relates to energy use and renewable energy generation.

When school is out, GCEA will continue to use the weather station data to monitor conditions for service calls in the Lake City area. GCEA Energy Use Specialist Alantha Garrison hopes the data can help cooperative members to better understand their utility bills, as well. Both Garrison and Virden are observers for the National Weather Service, so they appreciate the value of accurate weather information.

We look forward to following GCEA and the community as they put their weather data to use in the coming year. You can read more about the weather station in the GCEA News (Page 9). To learn more about education tools available from Western’s Equipment Loan Program, contact Gary Hoffmann.

City of Palo Alto Utilities tests smart streetlights along El Camino Real

City seeking feedback on solar project

This fully integrated smart solar streetlight, one of nine along El Camino Real in Palo Alto, California, produces energy equivalent to power two streetlights. The city is asking residents  to give their opinions on the streetlights in an online survey.

This fully integrated smart solar streetlight, one of nine along El Camino Real in Palo Alto, California, produces energy equivalent to power two streetlights. The city is asking residents to give their opinions on the project in an online survey.

El Camino Real, a historic road that runs nearly the full length of California’s coastline, is making history again for its role in a six-month pilot project being conducted by the City of Palo Alto Utilities Redirecting to a non-government site (CPAU). In partnership with energy technology provider Petra Systems, Redirecting to a non-government site CPAU recently installed a string of nine smart solar streetlights along “The Royal Road.”

The installation is testing the potential to generate renewable energy on streetlight poles. Solar photovoltaic, or PV, modules placed high on the poles capture the sun’s energy and send it to the city’s electric grid. The technology could help transform ordinary streetlights into a network of distributed solar power generating assets.

Taking community’s pulse
The PV-fitted streetlights are located along a well-trafficked mile of El Camino Real. Interpretive signs in the area educate passers-by about the technology. “The pilot project area runs right by Stanford University, as well as soccer fields and parks, so residents will see what we are doing and be able to form an opinion about it,” noted CPAU Communications Manager Catherine Elvert. “We are encouraging community members to provide feedback through an online survey.”

The survey asks questions about residents’ support for CPAU increasing the use of solar power, and allows them to express concerns about aesthetics, light quality and other issues. “The customer response to these modules can help us gauge how aggressively to pursue this type of local generation,” Elvert added.

CPAU is engaged in several local solar initiatives as part of its ongoing commitment to invest in clean energy resources.

Innovating through partnership
Through its Program for Emerging Technologies, the municipal utility is able to “test drive” systems that may improve operations, create jobs and boost the sustainability of CPAU’s generation portfolio. Launched in 2012, the program seeks out and nurtures creative products and services that manage and better use electricity, gas, water and fiber optic services.

Partnering with high-tech companies keeps the cost of innovation down. The El Camino Solar Test project will increase Palo Alto’s renewable energy production at no cost to the city. Petra Systems offered CPAU the solar modules to evaluate their performance over the six-month pilot duration. The nine units are estimated to have a total nameplate capacity of about 2.25 kilowatts, with each solar module expected to produce 374 kilowatt-hours per year. That electricity is enough to power the equivalent of two streetlights, making the LED, or light-emitting diode, streetlights net producers of electricity.

Improving service, lowering costs
Project Manager Lindsay Joye pointed out that generation is just a small part of smart solar technology performance. “The technology goes well beyond self-powering to give the city greater control of its streetlight assets,” she said.

The modules are equipped with an LED light controller that allows the city to remotely turn streetlights on or off. The brightness of individual lights or groups of lights can be adjusted to accommodate the traffic levels in different neighborhoods, as well. On a citywide scale, the dimming function can provide even deeper energy savings from the already-efficient LED lamps, Joye noted.

The system offers additional features that can streamline maintenance and enhance public safety. The controller can flicker specific lights to help direct emergency response personnel when needed, and can notify the city immediately of a malfunctioning light, including the failure type and exact location. Elvert said, “If the city decides to expand the project, high-traffic roads and expressways would be good candidates for installations. With the smart-grid and remote control capabilities, there would be less need to put our crews in harm’s way.”
