Federal grant helps local businesses install alternative energy sources

Jerry Herring talks about the power inverters for his wind turbine and solar arrays. “This is the brains of the whole system,” he said. “I’m real proud of this.” Herring said the inverters convert the raw energy coming in from the turbine and panels to the standard Homer Electric Association uses.

A number of Kenai Peninsula businesses are installing renewable energy systems this winter due to a United States Department of Agriculture grant program that aided the purchases.

The USDA’s Renewable Energy for America Program targets small businesses and agricultural producers, said Chad Stovall, who helps administer the program in Alaska.

Stovall said that four of the five central Peninsula applicants received funding in 2011. On the entire Kenai Peninsula, 10 of 24 applicants were funded.

“The Kenai Peninsula usually gets the majority of the projects,” Stovall said.

One of the new projects is out Funny River Road near Brown Lake, where Jerry Herring has his home and office. Herring, the founder of Central Alaska Engineering, received a REAP grant from the 2011 cycle. His turbine was installed at the end of November. 

Herring said that getting the turbine was a way of putting his money where his mouth is.

“As an engineer, I’m into renewable energy,” Herring said.

The grant, plus a federal tax credit that also incentivized the purchase, made the turbine feasible.

“With the grant, it makes the project economically feasible while on the grid with a net metering scheme,” Herring said.

That net metering scheme means that Herring can sell his power back to Homer Electric Association when he doesn’t need it.

His turbine is a 6-kilowatt-hour Kingspan, mounted on a 48-foot pole. It can produce 6 kilowatt-hours of energy in an hour when the wind is blowing at 25 mph. The turbine needs about four or five mph winds to start spinning, and six mph winds to start producing energy.

That wind also needs to be consistent, not fluctuating in speed too much, for the power to integrate into the grid. Herring said the big wind events are when the turbines really generate a good chunk of power. 

Assuming the cost of power goes up in the coming decades, Herring said the turbine should pay itself off in about 15 years. The payoff comes when the cost of the turbine matches the amount he’ll save on his electric bill. The turbine should last about 20 to 25 years.

Herring hired Alaskan Wind Industries to write the grant and help him plan for the turbine. They evaluated several models and types of systems before determining that the Kingspan was the best fit, he said.

Stovall credited local applicants’ success at earning REAP grants largely to the work of Alaskan Wind Industries in writing the grants.

Nadia Daggett, the operations manager at AWI, said her firm has helped with about 20 USDA applications over the past few years for wind and solar projects. This was the company’s third year in assisting with the grants, and all six wind turbine applications they helped submit this year were funded.

Daggett said AWI added a financial team to help with grant writing in 2009.

“We do everything in house and that makes it more viable for our clients,” Daggett said.

Stovall said AWI also works to help find the appropriate turbine for each applicant, doing wind and resource evaluations and matching energy use with energy production.

The turbine Herring chose is a common choice for the Kenai Peninsula. AWI helped Warren Johnson at Bear Lake Lodge get a grant for a similar turbine on a shorter pole.

Herring said he chose his turbine in part because its design makes it easier to maintain. It is on a tiltable pole, making maintenance easier and cheaper. That’s important, because he doesn’t want to spend all the money he saves on electricity just keeping it running, Herring said.

“This is a really good turbine, the way it is set up,” Herring said.

The turbine also fits his energy needs — he says he uses more power than a home would because of his shop. And it can withstand winds up to about 100 mph, which was important for Herring’s location, where the wind can get pretty strong.

Herring’s turbine will do more than just produce energy for his shoffice — the term he uses to refer to the combined shop and office he built this spring for his business. He also wants to add some alternative energy work to his business.

Herring’s shop includes a set of power inverters, which transform raw power from his wind turbine and two recently-installed solar arrays into the clean power HEA uses for its customers. That conversion is done in inverter boxes, with displays telling Herring how much energy he’s producing and what the system is doing.

The inverter also acts as a sort of filter. Herring’s power will only sync with HEA’s grid when both sources match HEA’s standards. That means that if the power is irregular on Herring’s end, or if HEA is having outages that interrupt the supply, it won’t link them up.

“This is the brains of the whole system right there,” he said.

Designing it took some work, because the inverter has to match the size of the alternative energy sources. Herring said AWI and other local businesses helped him with designing and installing the control center.

“I’m real proud of this ... been a long process,” he said.

Herring said he would like to be able to sign off on the designs for such control areas as part of his engineering firm’s business.

Herring said he’s pleased with how the grant has worked out, and supports the program that offers them.

“I think renewable energy is a good use of grant funds,” Herring said.

Stovall said the grants are tied to the Farm Bill, which is up for renewal in 2013. Next year’s funding is fairly solid, with about $70 million available for REAP grants across the nation.

Daggett said the deadline for the 2012 grants is the end of January, but the tax credits may expire at the end of this month, so the best bargains will come now, rather than later. The REAP grants are also best applied for early, she said.

“Usually the way they have it is first come, first serve,” Daggett said.

Was wondering

Is a GRANT the same as WELFARE? Would be interesting to revisit this 'white elephant' in 10 years and ask.... How's this working out for you?

Welfare?

I wish it were just that bad. It's subsidized CAPITALISM!! OH NO!!! When do the taxpayers get a return on their contribution? Would have been nice to see some statistics to date about amount of energy actually produced, amount sold back to PG&E, if the turbines can actually create enough energy at total costs that are less than PG&E can already produce it, etc..

Overreaction

When kenaibear2001 and Koma give up their Permanent Fund Dividends -- that's welfare too -- then I'll take their complaints seriously.

Wind Turbine Subsidies

This is a really good point on the permanent fund, Allen. One aspect that people seem to overlook, is the large amount of subsidies that are given to the oil companies to produce energy... and then sent overseas to our enemies. So, for our own community members to install a system that will provide energy (that will not only be used in our homeland, but also in our own communities of Alaska) I think is a much better government subsidy. If we knew that our government funds were going to stay in our own communities and be given to small businesses such as this, I believe many would feel a lot more comfortable contributing to their taxes. If however, Central Alaska Engineering Company developed this energy and then sent it overseas to our enemies... I believe most would have a harder time justifying his subsidy.

Please do not get me wrong, oil is the backbone of our Alaska state. However being able to diversify is not only needed, but a very smart and educated decision for our state. Being dependent on one technology or one company, leads to our inability to compete and lower prices. I think this is a great way to support independence in our state and I have no problem giving to our government when they support small businesses such as this.

On the question of production. This is a commercially viable system and currently in many remote locations in Alaska such as Nome Alaska for Alaska Airlines and lodges such as Bear Lake Lodge in the Aleutian Chain. The system in Nome Alaska and others in remote area's have hit over 130mph's, in these past few wind storms, and kept producing! This installation was not on the PG&E electrical grid and may not be viable for your location. However, with rates as high as 18 cents a kWh and as high as $1.50 in some remote area's, this is a great solution to stabilize energy costs. Central Alaska Engineering Company, not only installed an anemometer to verify production, but also reviewed return on investment and payoff calculations. With his subsidies and current cost of energy at his location, this small business will receive a return on investment as high as 10% and a payoff within 7 years. After the business receives the payoff, the free electric will help this small company keep employees, and grow for community.

We wish Central Alaska Engineering Company the best of luck and high winds!!
