As one of the UK’s leading wind measurement companies, Dulas works across the UK and internationally, conducting onshore and offshore work to help our clients optimise, develop, maintain and monitor wind installations.
Our wind consultancy services include site-finding, feasibility studies, planning, Environmental Impact Assessment and due diligence, and we work with the major wind utilities across the UK and Ireland. We are accredited members of the Institute of Environmental Management (IEMA).

Maximise your returns

Dulas have supported hundreds of field monitoring and measurements campaigns for our clients since we installed our first wind monitoring mast at Cemmaes wind farm in 1988.
Our development and planning consultants have a track record of more than 1GW of worth of successful projects under their belt. Our wide portfolio of valued clients range from multi-national utility companies to medium sized commercial developers, as well as individual landowners.
We offer full in-house compliance, industry accreditations and excellent health and safety credentials.

Enhancing your wind campaign through proven reliability

Each chain is only as good as its weakest link. At Dulas our passion for innovation goes hand in hand with this mantra. We recognise that for any product to be valuable, it has to first be dependable.
We offer rugged and well proven tubular masts that have been proven to withstand the most arduous conditions in the Scottish Highlands. Our attention to reliability doesn’t stop there however, and we ensure the full mast package, including instruments, data logger and communications, all meet our exacting quality and reliability standards.
It is also why we have teamed up with Leosphere to offer the WindCube in the UK & Ireland. The WindCube is a CE approved, integrated LiDAR system that has proven its reliability and bankability of data in all kinds of environments worldwide. We work closely with Leosphere who continually refine and improve their system, already the most advanced wind measurement technology available today.
We are also experts in the design and installation of bespoke remote power systems for long term operation through deep and dark North Atlantic winters. We customise the sizing depending on the job in hand and provide stable, clean and quiet back-up power through use of advanced Direct Methanol Fuel Cell technologies (DMFC).
All of these products are rigorously tested prior to deployment and we fully stand by them in the field. We offer a turnkey installation, operation and removal service with availability guarantees so that you can have both technical and commercial confidence that the job is ‘reliable first time’.

Frequently asked questions about wind power

Wind power or wind energy works on the principle of kinetic energy being converted into electrical energy. In simple terms the force of the wind that you feel on a windy day and blows you off your feet is captured by a device called a wind turbine and converted into electricity.

James Blyths Home Turbine (photo from 1891)

Wind power in the form of wooden windmills first appeared in Europe during the Middle Ages. The first historical records of their use in England date to the 11th or 12th centuries. By the 14th century, Dutch windmills were in use to drain areas of the Rhine delta.

The first electricity-generating wind turbine was a battery charging machine installed in July 1887 by Scottish academic James Blyth to light his holiday home in Marykirk, Scotland

That depends! Small wind turbines can be installed almost anywhere, but wouldn’t normally be large enough to keep a domestic property running in the winter. If you have plenty of space at your home and time to install and operate one, then a home wind turbine installation is very possible.

Environmental Impact Assessment is a formal process, now enshrined in UK law, that ensures certain types of development activity, including ‘green’ technology installations like wind or solar farms, undergo an assessment process before they are built.

An Environmental Impact Assessment (EIA) will assess and highlight what effects on the environment a development will have – and identify possible ways to prevent or mitigate adverse impacts – before a project is started.

Wind turbines have steadily increased in size since the first modern turbine design (3 bladed with a tubular tower) emerged out of Denmark in the later 1980’s and the early 1990’s. in 1994 a large turbine was considered to be 1 megawatt (MW) in size. Now the worlds largest turbine is the GE Haliade X Offshore turbine at a whopping 14 MW maximum output.

To put that into context, one single turbine could provide enough instantaneous power for about 3000-5000 average homes! Each rotation of the blades could power a single home for about two days. This enormous power output is possible due to the rotor blades that have a diameter of 220 metres and a maximum height of 260 metres.

Note: 1MW = 1,000 kW = 1,000,000 W. A standard electric kettle in your home is rated at 1500 Watts or 1.5 kW.

In order to ensure wind turbines are generating as much energy as possible, we need to monitor the speed of the wind. When it gets too windy, turbines need to shut down for safety reasons, but then need to be ready to start back up again when the windspeed drops.

Over time, windspeed monitoring reveals patterns that at first appear random but with analysis reveal  trends that help to predict future wind behaviour. With this knowledge we can make sure that turbines are ready to operate and create as much electricity as possible when conditions are favourable. On the other hand, if little or no wind is forecast, we can take the opportunity provided to schedule in operational maintenance that helps extend the life of the turbines.

An anemometer is any device used for measuring wind speed and direction. Typical anemometers feature a vertical shaft to which cups are attached. As the wind hits these cups, they drive the shaft around. The speed of rotation is proportional to the speed of the wind, which a meter displays and records.

Yes! For measurement at 120m height it is necessary to build a special tower (a guyed lattice tower) upon which we can place various weather instruments, including the anemometers that measure the wind speed.

It is possible to measure even higher than this, approaching 200 metres or more. To achieve this we use a special kind of laser anemometer.

The laser anemometer works by sending out thousands of pulses of infrared light. When these pulses hit tiny dust particles in the air, some of the pulses are reflected back to the device and can be detected. The reflected pulses of energy contain the information we need to know about the air velocity in the atmosphere due something called the Doppler effect. This is where due to the movement of the particles the frequency of the pulse is slightly altered when reflected. The onboard computer of the laser anemometer automatically detects this change and decodes it into a meaningful measurement of the wind speed that we can use.

Modern laser anemometer systems (known as LiDARs) are highly sophisticated optical instruments that are the result of decades of research. The first LiDARs appeared in the early 1960’s in the USA where lasers were being used as experimental range finding devices.

Light Detection And Ranging.

The term LiDAR was originally a portmanteau of light and radar. It is now also used as an acronym of “light detection and ranging” or “laser imaging, detection, and ranging”.
