Higher, bigger and more reliable wind turbines are defining the future of offshore wind. Harsh environments demand the technology provider to come up with solutions that have high reliability and less maintenance requirements. It’s a journey GE (NYSE: GE) started years ago. It is yet another example of how GE is helping customers build wind farms in some of the most challenging locations.
Today, GE Power Conversion has successfully completed manufacturing the first serial PMG in GE Renewable’s offshore wind factory in Saint-Nazaire, which was inaugurated in late 2014. The factory is set up to have a capacity of manufacturing 100 generators per year.
As the first series, 300 generators are to be manufactured on-site. The first recently completed generator is to be installed in GE’s Haliade™ 150-6MW offshore wind turbine in Denmark. The turbine’s power yield is 15 percent higher than that of other same-generation wind turbines, each is capable of supplying 5,000 households per annum. The power supplied by these turbines will become increasingly cost-effective as the volume of generators coming out of the Saint-Nazaire factory increases.
This highly sophisticated production site uses the air-cushion system that has been implemented to move generators within the site. The innovative way of manufacturing eliminates the need of cranes within the factory, significantly driving down the infrastructure costs. The site is also equipped with a test bench, ensuring every generator coming out of the assembly line is ready to be deployed.
“The factory in Saint Nazaire is the first offshore wind manufacturing site in France. It is a milestone in the nation’s energy history. Now by leveraging technologies from different GE businesses—the GE Store, we are well positioned to bring clean offshore wind energy to the domestic market as well as export to regions beyond France where energy is needed,” said Frederic Maenhaut, Renewables Executive, GE Power Conversion.
The 6-MW PMG is one of the world’s largest generators ever built. Its direct drive system has no mechanical gearbox coupled to the generator. Low component count increases equipment reliability and therefore enables higher energy efficiency, which also leads to increased turbine availability. Less downtime and maintenance requirements ultimately can reduce the cost of wind energy.
The generator is split into three electrical circuits. In the unlikely event of two circuits going offline, the high level of redundancy enables the turbine to continuously produce power even in “degraded” mode. This is a critical element for offshore wind power plants as stormy weather and treacherous water can delay repair work for days or weeks, needless to mention the very high maintenance expenditure.
“Offshore wind is gaining increasing competitiveness in the power mix, and GE is well positioned to serve this industry. We developed this PMG technology five years ago. It is ideal for offshore setting, helping increase wind turbines’ availability and optimizing energy production,” said Maenhaut.
GE’s PMGs have been previously selected to be installed on Block Island, America’s first offshore wind farm, which will help generate 30 MW of electricity in 2016.
Is Wood Burning Sustainable For Your Home?
Wood is a classic heat source, whether we think about people gathered around a campfire or wood stoves in old cabins, but is it a sustainable source of heat in modern society? The answer is an ambivalent one. In certain settings, wood heat is an ideal solution, but for the majority of homes, it isn’t especially suitable. So what’s the tipping point?
Wood heat is ideal for small homes on large properties, for individuals who can gather their own wood, and who have modern wood burning ovens. A green approach to wood heat is one of biofuel on the smallest of scales.
Is Biofuel Green?
One of the reasons that wood heat is a source of so much divide in the eco-friendly community is that it’s a renewable resource and renewable has become synonymous with green. What wood heat isn’t, though, is clean or healthy. It lets off a significant amount of carbon and particulates, and trees certainly don’t grow as quickly as it’s consumed for heat.
Of course, wood is a much less harmful source of heat than coal, but for scientists interested in developing green energy sources, it makes more sense to focus on solar and wind power. Why, then, would they invest in improved wood burning technology?
Solar and wind technology are good large-scale energy solutions, but when it comes to small-space heating, wood has its own advantages. First, wood heat is in keeping with the DIY spirit of homesteaders and tiny house enthusiasts. These individuals are more likely to be driven to gather their own wood and live in small spaces that can be effectively heated as such.
Wood heat is also very effective on an individual scale because it requires very little infrastructure. Modern wood stoves made of steel rather than cast iron are built to EPA specifications, and the only additional necessary tools include a quality axe, somewhere to store the wood, and an appropriate covering to keep it dry. And all the wood can come from your own land.
Wood heat is also ideal for people living off the grid or in cold areas prone to frequent power outages, as it’s constantly reliable. Even if the power goes out, you know that you’ll be able to turn up the heat. That’s important if you live somewhere like Maine where the winters can get exceedingly cold. People have even successfully heated a 40’x34’ home with a single stove.
Benefits Of Biomass
The ultimate question regarding wood heat is whether any energy source that’s dangerous on the large scale is acceptable on a smaller one. For now, the best answer is that with a growing population and limited progress towards “pure” green energy, wood should remain a viable option, specifically because it’s used on a limited scale. Biomass heat is even included in the UK’s Renewable Heat Initiative and minor modifications can make it even more sustainable.
Wood stoves, when embraced in conjunction with pellet stoves, geothermal heating, and masonry heaters, all more efficient forms of sustainable heat, should be part of a modern energy strategy. Ultimately, we’re headed in the direction of diversified energy – all of it cleaner – and wood has a place in the big picture, serving small homes and off-the-grid structures, while solar, wind, and other large-scale initiatives fuel our cities.
7 Benefits You Should Consider Giving Your Energy Employees
As an energy startup, you’re always looking to offer the most competitive packages to entice top-tier talent. This can be tough, especially when trying to put something together that’s both affordable but also has perks that employees are after.
After all, this is an incredibly competitive field and one that’s constantly doing what it can to stay ahead. However, that’s why I’m bringing you a few helpful benefits that could be what bolsters you ahead of your competition. Check them out below:
One benefit commonly overlooked by companies is offering your employees financial advising services, which could help them tremendously in planning for their long-term goals with your firm. This includes anything from budgeting and savings plans to recommendations for credit repair services and investments. Try to take a look at if your energy company could bring on an extra person or two specifically for this role, as it will pay off tremendously regarding retention and employee happiness.
While often included in a lot of health benefits packages, offering your employees life insurance could be an excellent addition to your current perks. Although seldom used, life insurance is a small sign that shows you care about the life of their family beyond just office hours. Additionally, at such a low cost, this is a pretty simple aspect to add to your packages. Try contacting some brokers or insurance agents to see if you can find a policy that’s right for your firm.
Dedicated Time To Enjoy Their Hobbies
Although something seen more often in startups in Silicon Valley, having dedicated office time for employees to enjoy their passions is something that has shown great results. Whether it be learning the piano or taking on building a video game, having your team spend some time on the things they truly enjoy can translate to increased productivity. Why? Because giving them the ability to better themselves, they’ll in turn bring that to their work as well.
The Ability To Work Remotely
It’s no secret that a lot of employers despise the idea of letting their employees work remotely. However, it’s actually proven to hold some amazing benefits. According to Global Workplace Analytics, 95% of employers that allow their employees to telework reported an increased rate of retention, saving on both turnover and sick days. Depending on the needs of each individual role, this can be a strategy to implement either whenever your team wants or on assigned days. Either way, this is one perk almost everyone will love.
Even though it’s mandated for companies with over 50 employees, offering health insurance regardless is arguably a benefit well received across the board. In fact, as noted in research compiled by KFF, 28.6% of employers with less than 50 people still offered health care. Why is that the case? Because it shows you care about their well-being, and know that a healthy employee is one that doesn’t have to worry about astronomical medical bills.
Unlimited Time Off
This is a perk that almost no employer offers but should be regarded as something to consider. According to The Washington Post, only 1-2% of companies offer unlimited vacation, which it’s easy to see why. A true “unlimited vacation” program could be a firm’s worse nightmare, with employees skipping out every other week to enjoy themselves. However, with the right model in place that rewards hard work with days off, your employees will absolutely adore this policy.
A Full Pantry
Finally, having a pantry full of food can be one perk that’s not only relatively inexpensive but also adds to the value of the workplace. As noted by USA Today, when surveying employees who had snacks versus those who didn’t, 67% of those who did reported they were “very happy” with their work life. You’d be surprised at how much of a difference this could make, especially when considering the price point. Consider adding a kitchen to your office if you haven’t already, and always keep the snacks and drinks everyone wants fully stocked. Doing so will increase morale tremendously.
Compiling a great package for your energy company is going to take some time in looking at what you can afford versus what’s the most you can offer. While it might mean cutting back in other areas, having a workforce that feels like you genuinely want to take care of them can take you far. And with so many different benefits to include in your energy company’s package, which one is your favorite? Comment with your answers below!
