Knowing Wind Farms’ Limits Can Help Prevent Utility Disruptions

As scientists warn that the increase in extreme weather events shows no signs of stopping, experts say it’s important as ever to prepare renewable sources for the conditions.

Iowa gets more than 40% of its power from wind energy, and for the most part, wind turbines can be weatherized to operate in winter weather conditions.

Tad Miller, regional director of field operations for energy company EDF Renewables, said cold-weather packages for wind turbines can range from using thinner oil – like you would do for your car in a cold climate – to putting heaters in the gearboxes or even on the blades.

“Every manufacturer has additions or changes they can make to adapt it to their environment that will make it more more reliable there and higher performance,” said Miller.

There are limits, and some of Iowa’s wind turbines were shut down during the 2019 polar vortex, when the Hawkeye State saw record-breaking cold temperatures, reaching negative 30 degrees Fahrenheit.

Miller said manufacturers and operators are always trying to find new ways to make improvements.

Natalie McIntire, a technical consultant with the Clean Grid Alliance, said since the polar-vortex event, Iowa’s regional transmission operator has been working to incorporate data about what the wind turbines and other power sources’ capabilities are – so that weather forecasting can help them plan ahead for managing power during future extreme weather events.

“They will know in advance,” said McIntire, “‘oh, we’re going to need to make sure that we have other resources available, because we can see that the temperatures are going to drop so low tomorrow that some of our wind plants may not be available.'”

She said if temperatures shut down wind farms in states like Iowa and Minnesota, for example, utilities within the network but unaffected by the weather could contribute resources to help.

How can Energy Audits inform your Net Zero Strategy?

Image
Many organisations are already in the habit of undertaking energy audits to highlight where energy and water efficiencies can be made, save on utility costs, and reduce carbon emissions. Unfortunately, the sad reality of many energy audits and surveys (especially ones that are completed for compliance with ESOS), is that once they are completed, the report is often tucked away into a ‘virtual’ drawer, never to be seen again. But what if there was another use for that forgotten energy audit? Did you know that it could actually be a really useful business tool to help get you started on your net zero journey? To help you harness that data in a practical way, Energy Services Analyst, Rhiannon Farquhar explains what makes energy audits so essential to carbon management and how they can be used to get your business on the path to net zero. So, what are energy audits? To put it simply, an energy audit is an assessment of the energy needs and efficiency of a building (or process), which

Garden Offices | The Ultimate Work from Home Solution for 2021

The Pros and Cons of Working from Home Working from home was not so long ago considered a perk of the job, however, the much-longed-for 30-second commute, for many of us, has finally become a realisation. Prior to the global pandemic, we would have spent 492 days of our lives commuting to and from work and inevitably, Covid-19 has brought about a catalyst of change. Businesses are now seeing the benefits of reducing costs by giving up office spaces, and with commuting now significantly reduced, one of the biggest winners out of this situation is the environment. With this in mind, there’s no doubt that the “new normal” of home working is, quite clearly, here to stay. The general consensus is that working from home is wholly positive and can provide a better work-life balance. Whilst this is true, there is evidence to suggest that this can be quite the opposite, with staff working later than usual as they battle to “switch-off” when their working day is over. So, what’s the solutio

Forgiveness Plan Would Remove One-Third of Students’ Loan Debt

Image
About one in three Idahoans who have federal student-loan debt would see it erased entirely if the Biden administration goes forward with a $10,000 forgiveness plan. That’s according to analysis from the website Student Loan Hero . President Joe Biden is considering eliminating the debt through executive order. Andrew Pentis, a senior writer and certified student loan counselor at Student Loan Hero, said the average monthly loan repayment in Idaho is $274. “Whether you have more or less than $10,000 worth of student loans left to repay, this dose of forgiveness would be hugely helpful, in either getting rid of your debt or shrinking it considerably,” said Pentis. “So certainly, if you’re a borrower in Idaho, you’d be rooting for something like this to happen.” The Trump administration paused federal student loan repayments in March 2020 during the pandemic. Biden extended the pause on his first day in office through at least October 1. Some Democrats want the Biden administration
