Trends & Concepts

Internet of things, wind turbines and ThingMonk the conference.

This post was written by and was published at Internet of things, wind turbines and ThingMonk the conference.

Back in 2009 I remember attending Logica’s analyst day in Lisbon and being very impressed with their Renewables Management System (RMS) – a windfarm management desktop application which was at the time managing a live feed of 300-400 data points from 2,000 wind turbines all over the Iberian peninsula.

Logica has since gone through a merger/acquisition process and is now known as CGI. I’m not sure what the status of their RMS solution is now, but I was reminded of it when I attended SAP TechEd in Las Vegas recently.

At the event SAP’s Benjamin Wesson gave me a demonstration of an internet of things (IoT) solution SAP have developed. The demo app, as can be seen in the video above, showcases how a windfarm manager can manage remote (even offshore) windturbines, see the status of any errors, create/manage trouble tickets, see schematics, and deploy resources based on proximity and availability. All from a tablet.

As we head into an era where more and more devices are being connected to the Internet, creating this Internet of Things, we enter a time when we can interact with and control everything from large offshore windfarms, to light switches in our home, from our device of choice (computer, tablet, smartphone).

The implications of this are still far from clear, but it is plain to see that apart from the legitimate security and privacy concerns, the ability to measure and take charge of equipment at all times from wherever has massive potential ramifications for efficiency. Everything from “Did I leave the light on?”, to, “Do I need to alter the angle of that blade on that 6MW wind turbine in the North Atlantic?” can now be asked and answered from the screen of your device of choice.

If you want to learn more about the Internet of Things, I recommend you head along to our ThingMonk conference in London on Dec 3rd next. Benjamin Wesson will be speaking there, as will some other awesome speakers, and there’ll be great demo’s as well.

And if you can’t make it along, we plan to video as many of the talks as possible for subsequent publication.

And here is this week’s Green numbers:

  • 1.25 Gigawatts of Solar Thermal Power Approved in California in Past Two Days Will Double US Capacity

    “There’ve been multiple gigawatts of solar thermal power plants planned for various places in the California desert for some time, but finally some more of them are getting the approvals need so that construction can start: The US Bureau of Land Management has issued a final environmental impact statement for the 1,000 MW Blythe Solar Power Project; and the 250 MW Beacon Solar Energy project has received final California state approval as well.
    The smaller of the two first: Renewable Energy World reports NextEra Energy Resources has been given the green light by the California Energy Commission to begin construction on the 250 MW Beacon Solar Energy project.

  • Green roofs offer antidote to urban heat island effect

    Researchers at Columbia University have demonstrated that a layer of plants and earth can cut the rate of heat absorption through the roof of a building in summer by 84%

    Perhaps the greatest overall benefit of green roofs comes in tackling the “urban heat island” effect, which Gaffin suggests is responsible for two-thirds of New York’s localized warming over the last century. The conventional black rooftops that he calls “tar beaches” are major contributors to this phenomenon, absorbing and re-radiating the sun’s energy as heat. “We’re going to want to cool regional climate down, especially where people are living,” Gaffin noted. “So we’re going to have to confront the urban heat island effect.”

    While conventional roofs can reach temperatures of 80 °C at 1.00 p.m. even outside of high summer, green roofs always stay closer to ambient temperatures. “These [conventional roofs] are almost dangerously hot spaces,” Gaffin told environmentalresearchweb. “That’s a huge heat load that we can get rid of.”

    Plants in green roofs regulate their temperatures through evapotranspiration. “They evaporate copious amounts of water,” Gaffin explained. “That takes a lot of energy and means it’s a great way to stay cool.”

  • Creating 625,000 jobs and saving $64 billion through energy efficiency

    Energy efficiency is THE core climate solution. It’s the biggest low-carbon resource by far. “Efficiency Works” [PDF], a major new report by Bracken Hendricks, Bill Campbell, and Pen Goodale, finds that a straightforward set of policies aimed at upgrading just 40 percent of the residential and commercial building stock in the United States would:

    1. Create 625,000 sustained full-time jobs over a decade.
    2. Spark $500 billion in new investments to upgrade 50 million homes and office buildings.
    3. Generate as much as $64 billion a year in cost savings for U.S. ratepayers, freeing consumers to spend their money in more productive ways.

  • Cisco To Acquire Smart Grid Monitoring Tech Company Arch Rock

    Cisco this morning announced its intent to acquire privately-held Arch Rock, which specializes in IP-based wireless sensor network technology with a focus on energy and environmental monitoring and Smart Grid applications.

    Financial terms of the transaction are not being disclosed.

  • Carbon markets: HFC-23 – The smoking greenhouse gun

    ONE of the curiosities of carbon markets is that they do not just trade in carbon. Other greenhouse gases can be given a value, too—sometimes a very high one. Claims that these prices promote scammery are now prompting some searching questions.

    The gas at the centre of the controversy is HFC-23, a greenhouse gas which, on a weight-for-weight basis, is 14,800 times better at trapping heat than carbon dioxide. HFC-23 is produced as a by-product of the manufacture of HCFC-22, an ozone-destroying refrigerant. HCFC-22 is banned in developed countries, but developing countries can keep making it until 2030.

    The acronyms do not end there. Under the Clean Development Mechanism (CDM) of the United Nations HCFC-22 producers in developing countries that destroy, rather than release, their HFC-23 can be eligible for Certified Emission Reduction (CER) credits, which can then be traded in the European Union’s emissions-trading scheme. This allows companies to buy extra emissions reductions to meet their cap-and-trade obligations, and in so doing to transfer money to schemes reducing emissions in developing countries.

carbon neutrality, Climate Change

No James, we Irish are not complete gobshites

Or if we are, it is not for the reasons James thinks! James Corbett has a post today on his blog asking “Are we Irish complete gobshites?“. The post is lamenting the fact that we are not building wind farms to reduce our dependence on oil imports.

I would answer James in the comment section on his blog but

  1. the answer is complex and
  2. he has deployed a CAPTCHA on his blog which means commenting there is a pain 😛

I have talked about this in several of my talks about reducing ITs carbon footprint.

There are >2gW of outstanding applications for windfarms to come onto the electrical grid in Ireland. To put that in context, we typically use around 4.5gW of power in Ireland (fluctuating day/night and summer/winter, obviously). However, these applications are being held at bay by eirgrid, the grid management company.

Why are they holding these applications at bay? Are they rabidly anti-green? Maybe they are pro climate-change? No, the reason Eirgrid don’t want any more wind power on the grid is because it de-stabilises the network.

Consider the following scenario. It is 2am. Electricity demand across the country is at its lowest. There is a 40mph wind blowing across the country. Wind energy at this point can be supplying up to 30% of the country’s demand.

What happens now if the wind picks up to 50mph? The wind farms shut down to protect their mechanisms and suddenly Eirgrid are left scrambling trying to bring gas turbine stations online to meet the sudden fall-off of 30% of their supply. Gas turbine stations can take up to an hour to reach full generation capacity.

The more windfarms Eirgrid take onto the network, the greater a problem this becomes. Unless there was some kind of ready counter-balance to the instability of wind farms…
