December 09, 2020 – Wind Views | Turbine Blades
 Let’s talk about blades! (Wind turbine blades, that is.)

Last week, One Energy partnered with Ohio Energy Project (link) for a virtual field trip (link) of the North Findlay Wind Campus. (More on that below!) During the event, we received a question from Emma, an energy-curious student in Ohio. We’re excited to use this week’s edition of Wind Views to address Emma’s question: “how much does a blade weigh?” Here’s the answer:

The blades used in our 1.5 MW wind turbines weigh more than 18,000 pounds each – that’s more than the weight of four average cars combined!

In this week’s Wind Views, you can see turbine blades being transported at One Energy’s component yard, located in Findlay, Ohio.

 

About the Virtual Field Trip:

One Energy was honored to host Ohio Energy Project for a virtual field trip – reporting live from the North Findlay Wind Campus.

Tour guide Erica, an engineer at One Energy, led participants through an educational tour of the One Energy office, turbine component yard, and inside a wind turbine itself! Viewers learned about the wind energy industry, discovered careers in wind, and had their questions answered – in real time – from a wind energy expert!

If you missed the live stream of our virtual field trip, a recording is available here.

Thanks to the teachers, students, classrooms, and all who participated and made the field trip such an engaging event! Thanks also to Ohio Energy Project and the team who helped make this digital visit as exciting as the real thing.

In December 2020, Ohio Energy Project and One Energy partnered for a virtual field trip inviting students, teachers, and classrooms from across the state to enjoy an up-close tour of the North Findlay Wind Campus.

The educational event was hosted by Monique Heath, Education Coordinator with Ohio Energy Project, with Erica Johnson, Field Engineer with One Energy serving as tour guide. Participants were taken on a tour of One Energy’s headquarters, explored large turbine parts in the company’s component yard, and even went inside a turbine that directly powers a nearby manufacturing facility!

Ohio Energy Project has shared a recording of the event on YouTube, which can be viewed below or by clicking here.

Ever wonder how wind turbine blades work, why turbines are painted light gray, or what the inside of a turbine looks like? We answer those questions (and many more) during the 45-minute field trip.

An added bonus? You’ll hear what it’s like to work in wind energy from past One Energy interns and current employees in engineering, procurement, and analyst roles!

Thanks to the teachers, students, classrooms, and all who participated and made the field trip such an engaging event!

December 07, 2020 – Wind Study | Question 5

To solve today’s Wind Study, it may help to scroll down and take a look at last week’s Wind Energy Fact!

On Friday (December 4) we learned that when the North Findlay Wind Campus turbines are generating at full capacity, they complete 16 rotations per minute (RPM), which means the maximum tip speed is 163 mph. But what’s the tip speed of the blades when there are fewer rotations per minute?

Use the diagram, dimensions, and formula in today’s activity to calculate tip speed and rotor swept area , and check back Friday to see if you got it right!

Download today’s Wind Study homework question here, and be sure to share on Facebook and Twitter!

How fast can wind turbines spin? We get asked that a lot!

The maximum speed a turbine can spin – or more specifically, the maximum speed at the tip of spinning wind turbine blades – depends on the turbine. Wind turbine manufacturers provide all owners with information on how many rotations the rotor (three blades and a hub) on their specific turbine model can complete per minute, when generating at full capacity.

Our turbines at the North Findlay Wind Campus complete 16 rotations per minute at full capacity. And their maximum blade tip speed is 163 miles per hour! 

At full capacity and maximum speed, these wind turbines are generating their highest amounts of electricity – and directly powering manufacturers in our communities!

Think that’s pretty cool? Share it on Facebook, LinkedInInstagram, and Twitter!

December 04, 2020 – Wind Study | Answer 4

Wind Study answer time! On Monday, we asked you to calculate the radius for a crane lift, and whether it would be considered a “critical pick” during wind turbine construction.

With components weighing hundreds of thousands of pounds, these details are crucial for the One Energy team and our crane operators to know. Think you know the answers? Find out below! (If you haven’t read Monday’s question yet, click here.)

The answers to these questions can be downloaded via the link below.

Check back on Monday for a new Wind Study question, which will be posted to our Facebook and Twitter accounts as well!

What’s the difference between an economist and an accountant? The economist didn’t have enough personality to be an accountant.

Of course, this joke is funny because everyone knows that accounting is boring and thus, accountants are, too…right? Therefore, economists must be even worse!

Really, I just think the accounting industry has a branding issue. Why not call ourselves Scorekeepers? It would certainly make us sound more interesting. And in the end, keeping score is really what we’re doing. Capturing lots of data, nearly all in dollars, and spitting it out in some form of useful information that tells you something about your business. How much does it cost us to add a truck to our fleet of vehicles? How much should we charge for this new product? If we hire five new employees, what will that cost us “all in” (including all the benefits and taxes)? And the ever popular, “Did we make any money?”

The “art” of accounting, however, isn’t about answering those questions. It’s about presenting information in a way that is understandable, meaningful, useful, and valuable. Doing that requires a genuine understanding of your audience and a real appreciation for the fact that different audiences need different information presented in different ways. Different people in different positions will find different sets of information useful. The art of accounting is meeting the needs of your different audiences so that they, in turn, can make critical decisions that propel your organization forward. It’s the difference between reading the black and white box score in the sports section of the newspaper (boring!) and listening to a talented announcer describe the last play of the game as one team comes from behind to score in the last few seconds, pulling out an unbelievable win!

Accounting isn’t sexy. Well, not to most people. (Okay, honestly, not even to me.) But try thinking about any professional sporting event without the questions, “what’s the score?” or “who won?” crossing your mind. It’s like touching your nose with your elbow – you just can’t do it! (You can put your elbow down now.)

If you try thinking about financial statements or reports like a scorecard, perhaps they will be more interesting and maybe even less daunting! And if you think you need different information, more understandable information, or you don’t know how the information you’re getting applies to your job, then it’s probably time to have a conversation with your accountant. A good accountant will want to get you what you need, and a great accountant will find a way to make it interesting for you! I mean, we’re not economists, after all.

Anne Bain is the Head of Accounting at One Energy.

December 02, 2020 – Wind Views | Tower Stacking

Today’s Wind View shows two wind turbine tower sections being stacked during construction. Once all four sections have been stacked, the tower will be roughly 265 ft. tall and ready to be topped with the nacelle!

Visit page 4.1 Energy Terminology to learn more about these turbine components (towers, nacelles, and much more!). 

November 30, 2020 – Wind Study | Question 4

Happy Monday! In this week’s Wind Study we’re talking tables, metrics, and cranes capable of lifting hundreds of thousands of pounds!

To construct wind turbines, One Energy uses a crane to lift and install components, such as the generator pictured below (which weighs 101,200 pounds). For this week’s Wind Study, learn about “critical picks”, how to read tables and crane load charts, and help us answer two math problems about lifting components with a crane. 

Download this week’s Wind Study Homework Question (and check back Friday for the answer!) This question can also be found on our Facebook and Twitter accounts.

This week’s view features our Wind for Industry project located in Ottawa, Ohio. Rather than sending power to the electric grid, this 1.5 MW utility-scale wind turbine directly powers a local manufacturing facility.

November 25, 2020 – Technician Talk | FAA Lights

Introducing Technician Talk! Check back every month for a new tutorial from one of One Energy’s own wind technicians. Learn a new skill, get to know our gear, watch us complete a task, and meet the crew! Get down to the nitty gritty of building a Wind for Industry project! This week, we’re learning from OE Technician Justin Bruns.

Curious why wind turbines (and other tall structures) flash red at night?

Those red blinking lights are called FAA Obstruction Lights – FAA stands for the Federal Aviation Administration. These lights help illuminate tall structures, such as wind turbines, so that aircraft can easily identify and avoid them.

Justin will explain all about FAA lights – and what happens if an FAA light stops functioning on a wind turbine.
