After a long wait, the ZEPS Electric Bus has finally begun rolling on the streets in the Tri-Cities. Last October, I first reported that Ben Franklin Transit would be launching an all-electric battery-powered bus built by Complete Coach Works of Riverside CA. While it was supposed to begin service last year, delays in the building of the bus (mainly waiting on the batteries to arrive from China) pushed the launch back to now. The bus has actually been in the Tri-Cities since last month, but it did not go into service immediately as BFT staff needed time to familiarize themselves with the bus, as well as clear up any potential operational problems (such as low hanging branches on the routes it is running on).

On Tuesday, I just happened to be at Knight Street TC in Richland on my way home when I saw the ZEPS Electric Bus arriving as an inbound Route 26. Since I’d missed a few previous chances at PR events to see the bus, I jumped at this chance and took a ride as it ran a trip on Route 23. Along the way, I took some notes about the bus:

  • As expected, the bus is very quiet. With no diesel engine or transmission to make noise, the only sound you can hear is the hum of the electric motor and the A/C unit running.
  • When accelerating from 0mph, the bus has a bit of a rattle (imagine a bad shift on a manual transmission car). This only lasts a few seconds, and seems to be less intense when the bus operator accelerates faster.
  • 5-25mph is about the ideal speed range for the bus. Once it gets over that range, the bus starts to become more sensitive to small bumps on the road.
  • With the big battery box sitting on the roof, the bus ride is a bit stiffer. Going through corners, the bus has less “body roll,” but the suspension also strains a bit more in corners due to the added weight. The added weight also makes the bus sit a couple of inches lower, and along the way it did grind on the road a couple of times while passing through intersections in North Richland.
  • Anyone who rides a Gillig Low Floor regularly is familiar with the interior rattle, but on the ZEPS Electric Bus it is fairly muted. Once the bus gets past 25mph, you do start to hear some of those rattles though.
  • To extend the range of the bus, there is a regenerative braking system installed. The average rider won’t notice it, but a trained ear can tell when it kicks in. The transition between acceleration and regenerative braking is quite smooth, unlike the slight kick you sometimes feel on a Gillig HEV.
  • To lighten the bus up a bit, new seating was installed. Unlike the typical fully padded seats one can find in BFT’s buses (excluding ones bought used), these are ergonomic seats made of composite material. I heard multiple operators state that they were uncomfortable, but I found them perfectly fine. The floor was also redone, with the plywood subfloor replaced by a composite with a rubber flooring on top.
  • In the operators area, there are a couple noticeable changes. Where the transmission control normally sits, there is a large toggle switch and a yellow push button. On the right side of the dash, a 7-inch screen has been installed. On the screen, there are two gauges for the regenerative braking and the battery charge. While passing through the Stevens Center area, the bus operator exclaimed out loud that the bus had only used 25% of the charge. While it’s obviously an add-on to the usual Gillig Low Floor dashboard, it is molded in so it looks like it belongs there.
  • On the exterior of the bus, the most noticable change is the special livery. New LED headlights were also installed, and two overhead A/C units are on the roof of the bus (the usual A/C housing at the back of the bus was vacated for the electric drivetrain system).

Overall, I had pretty high expectations for the ZEPS Electric Bus and it did not disappoint. Based on what I’ve been told by BFT officials, the bus will be going into service during peak hours only for the time being. During both peak periods, it runs on a Route 23/26 interline. In the near future, there are also plans to test it on other local routes, but it will unlikely be seen on any intercity routes.

My recommendation to anyone who has the chance to take a ride on the ZEPS Electric Bus is to do so. As I’ve said before, this very well may be a small step into the future of public transportation.


More ZEPS Electric Buses On The Way?

Back in October, I first reported on the BFT Electric Bus Demonstration project. Since that time, there have been some updates. Perhaps the biggest and most important is that the ZEPS Electric Bus was finally delivered on the evening of May 13th. Am I late in reporting this? You bet. However, I was trying to hold off on writing a post about this until I had a chance to get a close up look at the ZEPS Electric Bus and take some photos. However, after last night’s BFT board meeting, I figured I needed to share the latest update to this project, because it is a big deal.

After word got around about what Ben Franklin Transit was doing, other agencies got interested. Rather rapidly, a consortium of interested agencies formed, and now an application for a TIGER (Transportation Investment Generating Economic Recovery) Grant has been submitted. Officially submitted on June 3rd, the application is submitted under the name “US Bus – National Long Range Electric Bus Deployment Partnership.” BFT is the lead agency on this proposal, but there are quite a few partner agencies:

  • CALSTART (Pasadena CA)*
  • Clallam Transit (Port Angeles WA)
  • Washington State Department of Transportation (Olympia WA)**
  • Berks Area Regional Transportation Authority [BARTA] (Reading PA)
  • Santa Cruz Metropolitan Transit District [Santa Cruz Metro] (Santa Cruz CA)
  • Lane Transit District (Eugene OR)
  • East Contra Costa Transit Authority [Tri-Delta Transit] (Antioch CA)
  • Indianapolis Public Transportation Corporation [IndyGo] (Indianapolis IN)
  • OmniTrans (San Bernardino CA)
  • Gardena Municipal Bus Lines (Gardena CA)***
  • New York Metropolitan Transportation Authority (New York NY)
  • Kansas City International Airport (Kansas City MO)

* – CALSTART was the grantee of the funds for the original BFT Zeps Electric Bus
** – WSDOT is acting as a steward for rural agencies in WA, will distribute buses to 4-5 agencies
*** – Gardena Municipal Bus Lines runs the demonstration ZEPS Electric Bus built by Complete Coach Works

Included in the TIGER Grant application are letters of support from all the participating agencies, along with letters of support from Senator Richard D. Roth (31st District CA), Michael Kluse (Director of Pacific Northwest National Labratory), Joseph K. Lyou, Ph.D. (President and CEO of Coalition for Clean Air), and Larry Rubio (CEO of Riverside Transit Agency).

Between all the different agencies, the proposal is for 41 buses to be built. All agencies (not counting CALSTART) will be providing at least 2 buses to be rebuilt as ZEPS Electric Buses. The grant funds will pay for the installation of charging stations and subsidize operating costs, with each agency providing their own local match. As the lead agency in this project, BFT will also be adding some additional infrastructure. The most noticeable part will be the installation of a solar array above the bus yard, which will be used to power the electric charging stations (this will be the 1st in the US, 5th internationally). BFT will also be working in collaboration with Columbia Basin College (CBC) to develop the “US Zero Emission Bus Center of Excellence,” which will be a resource and training/research center for agencies across the country.

While the participating agencies are only “ankle-deep” into this project at this point, I think the likelihood of this TIGER Grant being approved is highly likely. If it is approved, it will be a game changer for all the participating agencies, but especially for lead agency Ben Franklin Transit. For all we know, this may be just a small first step into the future of transit.

UPDATE 9/5/13: The final list of TIGER grant awards for 2013 has been released today, and sadly this project was not on the list. Looking back on it, there are several possible reasons as to why the “US Bus – National Long Range Electric Bus Deployment Partnership” was not selected. For starters, if approved it would have been the largest TIGER grant this year, at over $39 million. (There have only been 12 grants over that amount in the history of the TIGER program, 11 in 2009 and 1 in 2010.) Also, the multitude of agencies involved in this grant application may have been an issue, as there is not a whole lot of precedence for multiple agencies/jurisdictions in the TIGER program. All past TIGER grants that did involve multiple agencies/jurisdictions were neighbors and shared a common interest, such as the Mississippi River Bridges ITS application in 2011 that involved Mississippi, Arkansas, and Lousiana, or the Memorial Bridge Replacement application in Portsmouth NH and Kittery ME from 2010. Finally, it is worth noting that the most successful TIGER grants have a lot of local and financial support, and it’s not very clear if this consortium of agencies had that. It’s assumed that all the involved agencies accepted the proposed costs of this plan, but some of them may not have had the money budgeted away for a local match. As noted in this post originally, this consortium formed rather rapidly before the June 3rd application deadline, so there wasn’t much time to drum up major support for this project.

Even though this project will not be happening, there still is good news to come out of today’s final list of TIGER grants. Previously unknown to myself or fellow blogger Curt Ailes at Urban Indy, IndyGo (the local transit agency in Indianapolis) applied for and was awarded $10 million for at least 22 electric buses. The official press release explains more about the project:

INDIANAPOLIS (September 5, 2013) – This morning, the Federal Transit Administration (FTA) announced the award of $10M in Transportation Investment Generating Economic Recovery (TIGER) funds to IndyGo, the public transit agency for Indianapolis, Indiana. The highly competitive grant program prioritizes transportation projects that have significant impact on outcomes relating to state of good repair, economic competitiveness, livability, environmental sustainability and safety of the nation’s transportation infrastructure. The award of these funds will allow IndyGo to recondition and repower upwards of 22 transit vehicles, employing a zero-emissions electric propulsion system.

“As a strong proponent of improving transit for Hoosiers, I was glad to lend my support to this effort,” said Congressman André Carson. “Recycling used buses to make them fully electric will save us money, reduce waste, energy consumption and dependence on foreign oil, and maintain a quality transit system for years to come.”

The 22 remanufactured electric propulsion transit buses will be completely rebuilt to like-new condition with a zero-emissions drive system and will cost approximately $555,000 each, comparable to a brand new diesel bus. In addition to the cost to rebuild and repower the vehicles, the grant also funds necessary charging stations at the IndyGo facility and the Transit Center, which is set to open in late 2015.

“Today’s announcement of the TIGER grant award supports our city’s goal to reduce dependence on foreign oil,” said Greg Ballard, Mayor of Indianapolis. “By introducing zero emission, post-oil technology public transit buses, we’re making another successful leap in the right direction.”

The new electric buses will have a range of approximately 100 miles and will provide the equivalent of 16 MPG, quadruple the energy efficiency of a conventional diesel bus. The 22 new electric vehicles will be used on routes that are compatible with the range limitations and will allow IndyGo to retire some of its older buses.

“IndyGo is thrilled to have the opportunity to be on the leading edge of the transit industry with the project,” said Michael terry, IndyGo President and CEO. “We’re always investigating innovative ways to refresh our fleet and use technology to build capacity with the limited funds that are available to operate vital transit services.”

While not spelled out in the press release, it is clearly apparent that these will be ZEPS Electric Buses built by Complete Coach Works. For a refresher, this is same type of electric bus that Ben Franklin Transit is currently running and the same type that the consortium of agencies was going to use. While I am disappointed that we won’t be seeing more ZEPS Buses in the Tri-Cities (or at least not yet), it is quite exciting to see other agencies taking the plunge and investing in this type of electric bus. This is a big deal for Complete Coach Works, as this will be the first multi-bus order of the ZEPS Bus. As previously mentioned before, there are only two ZEPS Buses in existence currently, one operating as a demonstration unit and sometimes part of the Gardena Municipal Bus Lines fleet while the bus at BFT is the first official production unit. The demonstration unit made an appearance at the APTA Conference earlier this year in Indianapolis, which likely sold officials at IndyGo on the technology. Based on the positive reception that the ZEPS Bus has received here in the Tri-Cities, I think it’ll do quite well in Indianapolis.

BYD E-Bus Arrives In Tri-Cities

After spending last month up in Spokane on STA bus routes, the BYD E-Bus was delivered to Ben Franklin Transit yesterday afternoon.

I first broke the news of this on my Twitter feed, and later in the night local TV station KEPR also had coverage about the bus.

A schedule for where and when the BYD E-Bus will be running this month is still being determined, but keep an eye out here for that information. It’s also worth mentioning again that Ben Franklin Transit already has another electric bus, the ZEPS Bus, in their fleet, so this will make for an interesting side-by-side comparison of the two different technologies.

BFT Electric Bus Demonstration

Zero Emission Propulsion System (ZEPS) Bus

As part of an initiative to be an innovator in green technology, Ben Franklin Transit will be participating in a demonstration project of an all-electric bus this year. Teaming up with Complete Coach Works of Riverside CA, the project will be funded with a grant for $750,000 that CalSTART (Pasendena CA), received. (It’s unclear who the grant is from.)

The Zero Emission Propulsion System (ZEPS) Bus is perhaps one of the most promising electric-powered buses to be developed yet. Promising a MPGe of 16.04, the bus is powered with a 180kw electric motor rated at 241hp. For batteries, the ZEPS Bus uses Lithium-Iron Phosphate batteries, which have many benefits, including longer cycle life, slower rate of capacity loss, more chemically stable, and less susceptible to overheating/igniting. With a range of 120-150 miles, the ZEPS Bus comes closer to equally the range of similar diesel buses than any other electric bus built before. The bus is also capable of running at highway speeds and powering an A/C unit while in motion.

Unlike most electric buses, the ZEPS Bus is not built completely from scratch. Using pre-existing buses that have already been carrying passengers, CCW rebuilds the bus and replaces the diesel engine/transmission with the ZEPS Bus drivetrain system. For the BFT Zeps Bus, the unit being rebuilt is #248, a 2005 Gillig 40′ Low Floor. #248 had been recently damaged in an accident in Richland and was already undergoing restoration at a facility in Las Vegas, so the timing of the ZEPS Bus project works out quite well. The rebuild of #248 into a ZEPS Bus is extensive enough that it will be issued a new VIN number and title. In regards to facilities, no major modifications will be needed beyond a charging station to be installed at BFT’s base. CCW states that it takes 6 hours to fully recharge the ZEPS Bus batteries, so it will be able to charge overnight and remain in service for most if not all of the service day.

According to CCW’s calculations, a single ZEPS Bus can remove 204 short tons of greenhouse gases per year when coupled with 100% renewable energy generation, and can save an agency $330,000 over 7 years in fuel and maintenance costs. With the Tri-Cities having hydro, solar, wind, and nuclear energy sources all in the immediate vicinity of the metro, the ZEPS Bus will easily be a 100% green technology initiative. Previously, BFT has done a demonstration of biodiesel in their entire fleet, and have had their new administration building certified as LEED Gold.

BFT staff have stated that the ZEPS Bus is set to debut sometime towards late fall or the end of the year. CCW was able to build the prototype ZEPS Bus in just 10 days, so there doesn’t seem to be too much of a risk of delays. Once the ZEPS Bus goes officially into service, I plan to head down to the Tri-Cities and check it out, as well as get some photos.

News Roundup 3/17/14

Ben Franklin Transit

BYD E-Bus Will Be Tested in the Tri-Cities
Currently undergoing testing in Spokane with Spokane Transit Authority, it has been confirmed that the BYD E-Bus is coming to the Tri-Cities next month. At this time, officials with BFT are still working on plans for where and when this bus will be running, but a press release should be put out towards the end of the month with that information. It has also been hinted that the ZEPS Bus, BFT’s current electric bus project, will be running at the same times as the BYD E-Bus, creating the opportunity to compare these two different technologies side by side.

New Bus Stop Signs Coming This Summer

Pending the approval of the Board of Directors tomorrow, bus riders in Chelan and Douglas Counties will be seeing some new bus stop signs installed. Over the years, the old bus stop signs have become faded with age, and a large number of them have the route numbers listed in a haphazard fashion with little organization and inconsistent fonts. The new bus stop signs, an example of them seen at right, work immensely to address this issue, as well as gain added visibility and an overall better look. Approximately 620 of them will be installed, covering every city and bus route in the Link Transit system. The costs for these new signs is $26,511.71 (including WA sales tax), which covers the signs and all the installation hardware.

Yakima Transit

Vote to cut the Yakima-Ellensburg Commuter and Sunday Service Tabled
As reported last week, Yakima Transit was looking in to the possibility of discontinuing the Yakima-Ellensburg Commuter and Sunday fixed-route service. Both services are largely funded with grants from WSDOT, and those funds are running out very soon, largely in part to higher than predicted maintenance costs in the case of the former. At the request of City Manager Tony O’Rourke, the vote was tabled as talks for new funding sources had picked up in the days since this was first announced. A meeting with officials from the involved parties and cities is tentatively scheduled for the end of the month, and this issue will likely come up again in the City Council meeting next month. In coverage from the Yakima Herald-Republic, it was mentioned that Yakima Transit and Hopesource had submitted a grant request to help purchase two new buses to run the route, so there may be hope yet.

Wenatchee Valley Shuttle Adds Stop at Columbia Station
Back in December, Wenatchee Valley Shuttle moved their Wenatchee stop from Olds Station (Easy Street) to Columbia Station in Downtown. With Link Transit, Amtrak, Northwestern Trailways, and the Apple Line all serving the station as well, it’ll make it much easier to connect to the shuttle.
