Cycling operations including on/off and load cycling at combined cycle and thermal power plants increase production and maintenance costs at these plants while reducing overall plant reliability. The higher rate of cycling stems primarily from additional variable renewable generation penetration into the grid, along with market pricing for gas fuel and emission restrictions on coal-fired units. The desire for faster starts and more frequent online times to meet market conditions increases the number and cumulative damage from gas turbine starts and load following operations. In particular, increasing the frequency of thermal transients with rapid gas turbine acceleration and high mass gas flows at higher exhaust temperatures reach the heat recovery steam generators (HRSG) and all this effects the gas turbine, along with the balance of plant and water chemistry. All of these factors ultimately reduce overall plant reliability and can significantly increase production and maintenance costs.
Power plant operators and maintenance professionals should plan to register and take part attend, along with finance and regulatory specialists who stand to gain insight into how cycling affects the cost of production and reliability.

Ride Across Wisconsin: Cyclists trek from La Crosse to Milwaukee
Ride Across Wisconsin ends in MilwaukeeThe Ride Across Wisconsin bike event from La Crosse to Milwaukee started Saturday. Some crossed the American Family Field finish line the same day.
MILWAUKEE – The Ride Across Wisconsin bike ride from La Crosse to Milwaukee got rolling Saturday, Aug. 19.
One by one, riders who completed the 235-mile trek crossed the finish line at American Family Field.
“I kind of just came here today to set my own pace and rode with another guy for 100 miles, and he pulled over, and I just kept riding my pace the whole way,” said Chris Stevens of New Richmond.

Stevens was the first to finish the race.
“This was 11…over 11 hours riding my bike. Beautiful sunrise and a beautiful day,” he said.
Ride Across Wisconsin 2023 ends at American Family Field
Now in its eighth year, organizers said Ride Across Wisconsin’s goal is to promote bike riding in the state and raise money for the Wisconsin Bike Fed – which promotes bike-friendly laws and projects.
La Crosse was the starting point, and hundreds of cyclists were up early at 5 a.m. to begin the ride. Wisconsin Dells was the halfway point.
“Started out good, dark. Everyone had headlights flashing,” said Johnathan Olson of Spring Grove, Illinois.

“It was awesome,” Stevens said.
On Thursday, because of Canadian wildfire smoke, the Wisconsin Department of Natural Resources issued an air quality advisory that was supposed to end Monday. Friday, that alert was canceled because of high winds.
Those winds had quite the impact on Saturday’s cyclists.
“There was a lot of headwind, and it picked up even more in the afternoon,” Olson said.
“Unfortunately, Milwaukee’s south of La Crosse and the wind was out of the south, so we spent a lot of time riding into the wind today which made it hard, but it was fun. It was a great day out there,” said Stevens.
Despite the wind, riders said the 235-mile race is worth it.
“Had a great day out there,” said Stevens.
A second wave of bicyclists participating in Ride Across Wisconsin will complete their trek to Milwaukee on Sunday. One important note for cyclists: Some of the counties they’ll be traveling through will be under a heat advisory.
Biking for beginners: Everything you need to know to plan your first ever cycling holiday
On your bike: Keep it simple on your first cycling holiday (Chris Warburton)
Thinking about going on your first cycling holiday? If the idea of free-wheeling exploration and the open road are calling your name, then this is the trip for you.
But where to begin when planning your first foray: Where should you go? What should you pack? Do you need to train? And how much bike maintenance knowledge is really necessary before you embark upon your first adventure?
Here’s our full cycling guide to help you start putting together your debut adventure, covering the recommended essentials (extra socks, optionally cute), how to choose your destination and accommodation, how to map your route, and all the essentials to ensure a smooth experience – even for the greenest of newbies.
Top tip: Go with at least one other person. They can help spur you on to cycle that bit further and provide support if anything goes awry. Player One, choose your cycle buddy…

Destination unknownWhere? That’s the big question. There are lots of UK options, from the Lakes to the Chiltern Cycleway to the Thames Path Canal. Dream big here. Routes can be linear, from Point A to Point B, or circular, starting and ending in the same place. If you opt for linear, start at the furthest point away; there’s something comforting about cycling in the direction of home.
Don’t go too remote for your first foray (Anna Shannon)
Don’t go too remote on your first trip, as you’ll be testing your (and your bike’s) ability. That way, if you need a respite or something goes wrong with your trusty steed, then a town or city shouldn’t be too far away to get what you need. Smaller places might not have a Halfords, for example, or might have a bike shop with unusual opening hours.
Top tipBook a bike space on the train to reach your starting point. Note where the bike storage sections are on the platform though, as you can’t wheel your bike through the train. Alternatively, if your bike isn’t suited to hills or anything more than the daily commute, consider hiring a bike to suit the terrain you’re going to be exploring once at your destination.
Planning your mileageHow many days and what distance do you want to cycle? A tough question for a beginner. It’s worth looking at the terrain, as two miles uphill is very different to five miles along a flat canal path. Weather and diversions are also part of the equation; allow extra time for the unexpected.
If you can comfortably walk three miles in an hour, then you’d most likely be able to cycle 8-10 miles per hour as a beginner on the flat. A realistic daily target could be 20 to 30 miles, taking around two to three hours. Have a total milage in mind (eg 90 miles over three days, doing 30 miles a day) as you’ll have more energy on day one. Three days would be a reasonable aim when starting out. Definitely go for a test ride, cycling for an hour or so to see how you and your bike feel.
You can cover more ground on flat terrain (Chris Warburton)
Twenty-odd miles a day may seem like a lot, but don’t let the number put you off – you can split this into smaller stints. Part of the joy of a cycle adventure is the journey itself, so don’t feel you need to cycle it in one go. Stop at that interesting looking tree or at that imposing castle, take a breath and feel inspired.
Top tipIt’s much, much easier to cycle when your tyres are properly inflated, so make sure you pump them up before setting off.
Mapping your routeDown to the nitty gritty – the route planning. There are great online tools to plan your route. Komoot lets you see what adventures other cyclists have tested before, with useful blogs and photos. Strava Premium has a heatmap so you can see popular cycle routes. Both have route-building functionality and ready-built route suggestions.
I’d suggest using at least part of the UK National Cycle Networks as they’re more cycle-friendly. Marked with red numbers on blue signs, these routes do go on roads, but nearly a third are traffic-free. (If the number is bracketed, this means you’re on the way to that network, but not actually on it).
Terrain and weatherAlfred Korzybski, a Polish-American engineer and philosopher, said: “The map is not the territory” – meaning plans are not reality. Mapping out your cycle route is important, but this is not the tangible reality of what you’ll experience.
That hill might be steeper than it looks on a map. That path may be more mud than grass. Or it might be surprisingly smooth. There might be headwinds, unavoidable diversions, or your legs might need a break.
Cycling terrains typically include tracks, trails, cycleways and roads. The terrain will impact your ease of ride. It can be tricky to translate how much of an incline a hill will be until you’re on it, but it will require some effort. Cornwall, for instance, has lots of steep climbs, so you’ll be working harder to get up all those hills. Aim for flatter routes for your first rodeo.
Even a cycle along the Thames can be an adventure (Chris Warburton)
Similarly, the weather will influence your speed, but if you have the right gear this will be OK. Think like a Scout and be prepared for anything.
