RENEW Wisconsin Electric Vehicle Blog: Now is the time for electric buses

RENEW Wisconsin Electric Vehicle Blog: Now is the time for electric buses

Electric buses offer quiet, peaceful, and fresh-smelling commutes for riders. Sounds pleasant, right?

In a previous blog, I highlighted the benefits of electric buses. They’re less polluting no matter where they operate, are more comfortable to ride in, cheaper to run, and can be powered by renewable energy. No wonder Wisconsin cities like Madison, Milwaukee, and Racine will see electric buses on their streets soon. These cities will be the first in Wisconsin to benefit from electric transit buses, but hopefully not the last.

Cities across the world are investing in electric buses

Cities all over the world are overhauling their bus fleets to replace dirty diesel with electric:

  • Medellín, Columbia will get 64 electric buses in August.
  • Moscow, Russia recently purchased 200 electric buses, some of which have been operating since last fall.
  • Santiago, Chile purchased 100 electric buses which should be deployed soon
  • Shenzhen, China has only electric buses. 16,000 of them.

Medellín and Moscow, Santiago and Shenzhen. While these cities are very different than Eau Claire or Green Bay, they show that electric buses make sense in locations around the world. And if they can do it, why can’t we?

Why aren’t all buses electric?

In short, the price tag. An electric bus costs almost twice as much as a diesel bus upfront, although they do save money in the long run on fuel and maintenance costs. But, since transit authorities operate with tight budgets, it’s often not feasible to prioritize electric buses unless we use creative financing methods to get electric buses for the same price as diesel buses.

The electric bus solution: PAYS®

We have solutions that can reduce the upfront cost barrier, save the bus owner money, and maximize the benefits that electric buses afford cities. It’s called Pay As You Save®, or PAYS®. PAYS allows the transit operator to purchase an electric bus with an investment from their utility, which the utility recovers over time through a fixed charge on the transit operator’s utility bill.

PAYS is a win, win, win solution that puts more electric buses on the road. The transit operator saves money each month thanks to those reduced fuel and maintenance expenses, even with the additional monthly charge. The utility makes money by selling more electricity, and we all benefit from less exposure to air pollution.

For more information about how PAYS works in practice, visit Clean Energy Works and watch their video above.

Proterra’s Solution: Leasing the Bus Battery

Electric bus manufacturer Proterra announced this week that they are scaling up their battery leasing program. Proterra’s program leases the bus battery to the customer, which brings the upfront cost of the bus down. Much like PAYS, the Proterra program aims to accelerate electric bus adoption by allowing transit operators to buy an electric bus for about the same price as a diesel bus. Operating funds that would have been spent on diesel fuel instead go toward the lease payment, leaving a little extra for savings.

Now is the time to move on electric buses

Buses last a long time. It’s important to start the transition now because any bus that hits the road now will likely last into the 2030s.

Ryan Popple, CEO of Proterra, summarized it well: “What worries me is that every time a new diesel bus deploys… You’re looking at 900,000 pounds of pollution on a 12-year deployment on a diesel bus.”

But it doesn’t have to be that way. Electric buses benefit the transit operator, riders, utilities, and citizens. Wisconsin has already started the transition to electric. Now is the time to speed it up by using these creative, proven financing models that are a win, win, win for Wisconsin. 

Richland County Unanimously Approves Nearly 50 MW Solar Farm!

Richland County Unanimously Approves Nearly 50 MW Solar Farm!

On Wednesday, April 10, the Richland County Zoning and Land Information Committee unanimously voted to usher in a brand new, nearly 50 megawatt solar farm!

Located two miles north of the Wisconsin River on agricultural lands owned by three local families, the Richland County Solar Farm will sit on roughly 500 acres. With a capacity of 49.9 megawatts (MW), the project is expected to produce enough electricity to offset the consumption from more than 13,000 average Wisconsin homes.

This project’s approval kicked off a momentous week for solar energy in Wisconsin when, the very next day, the Public Service Commission of Wisconsin approved two additional solar farm projects totaling 450 megawatts. You can read about Badger Hollow and the Two Creeks solar farm approvals here.

Wisconsin’s current fleet of solar farms range from one to five MW in size.  After the Richland County vote and the subsequent decisions at the PSC, it is  clear that large-scale projects are coming to Wisconsin. Scaling up to a renewable energy economy will require investments in utility-scale wind and solar projects like the Richland County Solar Farm.

This is the first solar project of this size to be approved at the county level. Richland officials took their time to carefully review the project proposal. The developer, Savion Energy (formerly Tradewind Energy), held two community meetings in September and November in the Village of Lone Rock. The County Zoning and Land Information Committee also heard from the public at two meetings in November 2018 and the most recent meeting in April 2019.

At these meetings, residents from Richland County brought up the need for local jobs and the economic investment the farm would bring, the need for clean energy, their concerns about climate change, as well as concerns for future generations. Minutes before the final vote, local resident Bob Simpson expressed support for the project by highlighting his worries for his grandchildren and that at some point “we are going to run out of gas.” But there were other residents who expressed concern about potential issues related to glare, aesthetics and the use of agricultural land for solar.

Bearing in mind the concerns raised in the public meetings, the final conditions for the Richland County Solar Farm Conditional Use Permit project include the following developer obligations:

  • Create a vegetative barrier between project lots and adjacent residences within 1000 feet of the project fence.
  • Provide screening on State Route 130 (which runs through the project site) within 1000 feet of the project fence.
  • Provide a detailed site plan including access and driveway permits.
  • Provide a decommissioning plan and financial security for decommissioning.

Immediately after the meeting, I caught up with Marc Couey, Richland County Supervisor and member of the Zoning and Land Information Committee. I asked him about the Richland County Solar Farm and he said, “We are going to run out of power without using alternative energies. It’s the right thing to do.”  I couldn’t agree more!

 

PSC Approves 5-fold Solar Expansion in Wisconsin

PSC Approves 5-fold Solar Expansion in Wisconsin

Today at its Open Meeting, the Wisconsin Public Service Commission approved five interrelated cases that will lead to a five-fold expansion of solar energy in Wisconsin.

The PSC approved:

  • The Badger Hollow Solar Farm project in Iowa County, totaling 300 megawatts. Badger Hollow could become the largest solar electric plant in the Midwest when completed. In addition, the PSC approved a “tie line” that will deliver Badger Hollow’s output to a nearby substation, where it will be injected into the existing southwest Wisconsin grid.
  • The Two Creeks Solar Project in Manitowoc County, totaling 150 megawatts. As with Badger Hollow, the PSC also approved a “tie line” that will deliver Two Creeks’ output to a nearby substation.
  • Finally, the PSC approved an application from two Wisconsin utilities, Wisconsin Public Service based in Green Bay and Madison Gas & Electric, to acquire a total of 300 megawatts of this new solar capacity. The utilities will acquire the entire Two Creeks Solar Farm and a 150 MW share of the Badger Hollow Solar Farm. Wisconsin Public Service will acquire a total of 200 MW and Madison Gas & Electric will acquire 100 MW.

By RENEW Wisconsin’s estimates, the state of Wisconsin closed 2018 with about 103 megawatts of solar power, about 80% of that residing on homes and buildings, directly serving the customers who bought the solar arrays.

When completed, the 450 megawatts of solar would produce about 1.3% of Wisconsin’s annual electricity consumption, and supply electricity equivalent to the usage of about 116,500 Wisconsin homes. Both projects should be operational by mid-2021.

RENEW Wisconsin’s Executive Director, Tyler Huebner, said, “We are very happy to see the Public Service Commission approve these solar projects and find that it is cost-effective for two of our major utilities to own and operate these plants.  It is a landmark day for solar energy in Wisconsin. Solar energy is a smart choice to meet the electricity needs of our citizens, businesses, and organizations, and without a state mandate to do so.  With solar energy, we will produce homegrown, healthy energy right here in Wisconsin for years to come, and provide substantial economic benefits to the landowners and local governments who will host these projects.”
Today’s approvals build momentum for large-scale solar as a resource for power suppliers and utilities in Wisconsin.

  • Three weeks ago, Dairyland Power Cooperative announced a commitment to purchase electricity from a 149 megawatt solar facility called Badger State Solar that would be located in Jefferson County. That project is subject to PSC approval as well.
  • Just yesterday, April 10, the Richland County Board of Zoning gave final, and unanimous, approval to the 49.9 megawatt Richland County Solar Project developed by Savion Energy to be located in the Town of Buena Vista.
  • In 2017, WPPI Energy announced it would purchase power from a 100 megawatt solar project near the Point Beach Nuclear Station. That project also will seek PSC approval in 2019.

Taken together, these five new solar projects account for approximately 749 megawatts of new solar power.  If all are approved and built, they would supply 2.1% of Wisconsin’s annual electricity needs, and produce enough power to equal the annual usage of about 185,000 homes in Wisconsin. Beyond these projects, at least 4,000 megawatts of additional large-scale solar projects are being explored and developed in Wisconsin.  We encourage you to learn more about large-scale solar energy, including our long list of questions and answers, at www.renewwisconsin.org/solarfarms.

Local Residents Discuss Wind Energy in Wisconsin

Local Residents Discuss Wind Energy in Wisconsin

On Monday March 25th RENEW Wisconsin facilitated a Wind Energy Education Event in Monroe, Wisconsin to answer questions from local residents about wind energy and new wind projects being proposed in Lafayette and Green Counties.

The Wind Education Event was hosted by Art Bartsch, local entrepreneur, green businesses innovator, and proprietor of the Monroe Super 8 Motel. Tyler Huebner, Executive Director of RENEW Wisconsin, kicked off the event with an overview of wind energy in Wisconsin. Then a panel of local experts including Mayor Dave Breunig (City of Darlington), Alder Steve Pickett (Darlington), and Tim McComish (Chair of Seymour Township Board), discussed their experiences with the Quilt Block Wind Farm located in neighboring Lafayette County. The event concluded with a demonstration of the power of wind energy from Dick Anderson and the student scientists of Kid Wind. Brodie Dockendorf (EDP Renewables) was also in attendance and addressed many technical questions about how wind turbines work. You can watch the video of the entire event on our Facebook page at this link.

Energized in 2017 and located wholly within Seymour Township in Lafayette County, Quilt Block serves as an excellent case study for future wind farms in the area. Quilt Block is a wind farm comprised of 49 modern turbines able to generate up to 2 MW each. Forthcoming wind farm projects planned in Wisconsin are likely to use similar scale or slightly larger turbines. The Sugar River Wind Farm proposed for southern Green County would host turbines with capacities of 2.625 MW and 2.75 MW.

The Quilt Block Wind Farm offers many economic benefits to Lafayette County. According to Mayor Dave Bruenig and Alderman Steve Pickett, the project construction supported local businesses through a variety of activities including the construction of a $700,000 warehouse and office space, the presence of the construction crews, and the full-time employees who purchased homes in the community. Mayor Dave Bruenig said that hotels, restaurants, automotive dealers in Darlington, and the neighboring communities saw benefits and that Green County could expect to see a “big economic boom” with the planned Sugar River wind farm.

The speakers emphasized the value of Wisconsin producing its own energy. Wisconsin imports $14 billion dollars worth of oil, coal, and gas, money that could be reinvested locally if we produced our own energy. Alder Steve Pickett said, “I think the energy that they’re going to be providing will help us be self-sustaining. And in the future that’s going to be very, very important, because if there’s any growth you’re going to need to have to have electricity to do it. And the only way you can do it is to start to generate your own.”  When speaking about his grown kids returning home he noted that, “we have a great life here and I’d like to keep it that way and part of that is being able to develop power within our own communities.”

The presenters also addressed questions about what it’s like living near the turbines. Tim McComish who runs a family farm with 250 Holsteins said “I live in the center of Seymour Township, they’re [the turbines] are all around me.” He added that they have started to become part of the landscape. “As crazy as it sounds, the 49 around me, I have to look once in a while to see where they’re at, because they blend in.  It’s amazing.” He added that the sound of the turbines, even the one on his property doesn’t cause any concern. “I myself, don’t even hear them at night. It’s part of the farm,” he added.

Below are some highlights of the event’s discussion. Questions are paraphrased for clarity.


Question: Does the electricity that’s made by your wind turbines stay in the county?

Brodie Dockendorf (EDP Renewables): We sell to Dairyland Power Cooperative out of La Crosse, Wisconsin. They actually sell electricity to Scenic Rivers, which is local, it’s sold locally to Seymour township. The dollar flow might go to La Crosse, Wisconsin, to Dairyland Power Cooperative, but the electricity, the electrons that are being generated, are actually used locally.


Question: Are people selling their houses because of the wind farm in your community? Have those homes sat on the market without buyers?

Mayor Breunig: No not at all. There’s a shortage of workers, there’s also a big shortage of housing. One of the things we got going up on one end of town is 24-unit housing. It didn’t affect us at all.

Tim McComish: There’s not a house available in our township for rent because there are workers looking for homes all the time.


Question: What about productivity of cows that live near wind turbines?

Tim McComish: I’m a dairy farmer, we’re still milking as good or better than before. It’s not affecting us.


Question: What about health issues and soil quality around wind turbines?

Tyler Huebner: Growing up in a town almost the exact same size as Monroe, eight thousand people, right now there are two hundred and sixty turbines recently built in my county, Poweshiek County. Twenty-four are being explored here in Green County versus two hundred and sixty. Everybody who’s going to lease those turbines to those developers or those utilities, they’re all corn farmers too. There’s at least ten times as many wind turbines in Iowa, and I have not heard anything come out of Iowa that would equate a loss in production or a change in the soil quality or anything like that related to wind.

In Iowa I have not heard any health complaints anywhere near where I grew up. I know that there is a lot on the internet that can be found, on this point there are some pretty reputable studies that have been done by Massachusetts Department of Environmental Health. I know that the Australian National Health Association have looked at these claims and basically found that, if you look at the scientific and the medical peer reviewed studies that there has not been found a link between human health impacts and living near wind turbines.

We also have references to a number of reputable studies on our website with more information about health and wind.


Question: Could someone explain to me how you take DC current and convert it to AC current?  Who monitors the IEEE standards?  

Brodie Dockendorf: The wind turbines actually generate electricity on alternating current.  They do not generate on DC. Up in the very top the generator is a squirrel cage motor, we turn that squirrel cage motor faster than what it’s supposed to. 1600 RPM squirrel cage motor is consuming electricity at 1580 RPMS. What we do is we spin it up faster. So at 1600 RPMs it meets an equilibrium where it doesn’t generate or consume electricity. When we spin it faster than 1600 RPMs at 1620 we actually start pushing alternating current.

It is a perfect sine wave, the same way a coal-fired power plant, a nuclear power plant, or a natural gas plant’s combined cycle natural gas plant, it’s the same way they are generating electricity. We don’t reinvent the wheel for this.

The same methods are used throughout the United States. There are turbines that will take a variable frequency. They take an inverter, like you would have a DC inverter for solar batteries, your car, and what they do is they actually convert it to DC and then they convert it right back to AC using an inverter.

As far as the standards of electricity go, if we put dirty electricity on the grid, MISO, is always monitoring.  The transmission companies (ATC and ITC) are monitoring our output. If we are even out of spec of the 60Hz cycle, they will open our breakers and shut us off.”


Question: What about harmonic distortion?

Brodie Dockendorf: There are harmonic filters on everything. We have harmonic filters in our substations. We also have phase compensation, big capacitor banks, any other electrical generator. We are scrutinized. We are a federally regulated power generation company, just like any other generator. There are some manufacturers [of wind turbines] that do [DC generation]. We’re scrutinized just like everybody else. We have to maintain no disturbance on the grid. If you cause disturbance on the grid, that kicks in fines. NERC and FERC regulations keep us in line. We can’t just go and do whatever we want on the grid and cause problems. If we do, [there are] big fines. Even if I miss a substation inspection – they can fine us up to $1,000,000 a day. We are regulated beyond what we can even imagine. So we are on top of our game.
