PI Renewables

Harnessing the power of wind

About PI Renewables

About PI Renewables – We develop onshore wind energy generation and specialise in medium sized wind farms (20-60MW) and smaller wind clusters (2-10MW).

We do so throughout Scotland from our central base near Livingston.

Our wind farms are project financed through special project ventures with strong investment partners.

To date, our investment partners have included Mistral Invest, the investment arm of an international shipping company, Platina Partners, a European private equity firm and AES as construction partner, a worldwide developer of power projects.

We have a strong management team who founded the company following many years experience from within the electricity industry, successfully developing power projects and energy related investments.

We develop projects in-house and maximise planning success by working closely with leading environmental and market advisors.

Adding to the 64MW of wind energy already consented and progressing through construction, we are currently developing over 100MW of new wind energy generation projects.


We cover all the necessary project implementation skills from land, planning, public relations, environmental, turbine, grid, civil and geotechnical, PPA, insurance and financing.

We cover most of the technical expertise in-house which we believe gives us an important edge.

By retaining design in-house we are able to devote unlimited time to achieving the best possible design, and can respond quickly and easily to community liason and planning feedback, as well as to any emerging design constraints.

We also engage industry leading advisors to support all of our work, and to take lead on specialised environmental impact assessment.

Over the years we have worked with advisors who are regarded to be amongst best in field, whether legal, techncial or environmental, and continue to do so.

Our Wind Clusters

We are normally developing around six Wind Cluster projects at any one time.

Our interest specialises in the larger farm and open lands of 150 acres or more, using MW rated wind turbines.

These MW rated turbines of typically 70m minimum overall height maximise electricity generation, also ensuring maximum environmental and economic benefit.

Our Wind Cluster projects normally comprise between 2 and 6 turbines.

In selecting favourable sites, we apply the same rigourous screening criteria to site selection as we do with our larger Wind Farm interests.

  • Specialise in Wind Clusters between 2 – 10MW
  • Significant up-front work to ensure appropriate and well sited development
  • Excellent in-house design and techical expertise

Our Wind Farms

We are presently developing in excess of 100MW of new wind farm projects throughout Scotland.

This is in addition to more than 64MW of consented wind farm capacity currently awaiting or progressing through construction.

We are dedicated to only building wind farms in the right locations, where technical, environmental and planning policy considerations are key factors in project selection and design.

  • Specialise in medium sized Wind Farms between 20 – 60MW
  • Significant up-front work to ensure appropriate and well sited development
  • Flat business structure for easier and faster decision making
  • Excellent in-house design and technical expertise

Electricity from the Wind – How It Works

Conventional power stations like gas, coal or even nuclear, all use the same kind of technology in the end to produce electricity – a generator.

A generator is like an electric motor operating in reverse.

Instead of applying electrcity to make it spin, when you spin it, it makes electricity!

The difference between types of power station then lie in the method of spinning the generator.

Gas fired stations for example combust gas in large jet engines similar to those used on aeroplanes.

Coal and nuclear stations produce steam which is expanded through steam turbines which turn the generators.

The fossi fuel types of course produce carbon emissions, whilst the nuclear ones radioactive waste.

The means by which wind turbines spin their generators will be obvious – the large rotor blades being driven round under the force of the wind.

The blades rotate relatively slowly and so a gearbox inside the turbine increases this up to the required spinning speed for the generator.

As the wind blows from different directions, the controls constantly monitor the wind direction and use electric motors to turn the top of the turbine.

There are no emissions from operating wind turbines and as the wind is not used up, wind energy is not only green but renewable. 

Government Drive

The Scottish Government now has a target to meet the equivalent of 100 per cent of our electricity needs from renewables by 2020.

Onshore wind generation is now a mainstream part of our energy mix and will continue to play a significant role in meeting this target – both in terms of generating capacity, and in providing the finance to expand other renewable energy sectors.

Scotland is one of the windiest countries in Europe, and the technology is mature, attractive to investors and cheaper than alternatives that can be deployed at scale.


Many people make claims about wind turbines and the effects they allegedly have.

This has led to a vast number of myths alleging they are inefficient, costly to run and noisy, together with claims of taking more energy to build than they ever make and harming tourism, birds and even humans.

To help put the record straight, Renewable UK, the professional body for the UK renewables industries, have collated the most popular myths and presented clear factual statements rebutting these claims.

Scottish Renewables, representing the renewables industries in Scotland, have further produced an onshore wind fact sheet whch more fully discusses the merits and facts behind wind energy.

We provide a quick link to these 2 publications for your consideration opposite.


If you have a suitable site, we will work hard to structure a deal that exceeds your expections and to develop the project with the same passion and rigour we do with all our projects.

We are consistently told by landowners that they value our approach and that we offer excellent market rates on straightforward terms.

Developers normally need to agree the legal agreement up front to mitigate their risk However, our normal approach is to get going with the project straight away under a very simple exclusivity agreement, delaying the main legals until a later date when time allows.

This speeds up the whole process by many months and in some cases by as much as a year if an important survey (such as a seasonal bird survey) would otherwise be missed.

It is difficult to summarise what constitutes a good site as we need to assess a whole range of matters including site details such as wind speed, topography, proximity to dwellings, important landscape or heritage designations and many other site factors, but also wider factors such as grid connection, cumulative development and planning policy.

Our computerised GIS system holds a wealth of information on all of this, including predicted wind speeds for the site.

We are able to run this fairly quickly and so determine whether the site is likely to offer good potential.

We are happy to do this at our cost on a non commital basis.

As a pre-requisite however, even for a small wind cluster site we require a minimum of 100 acres of land with no dwelling within about 400m.

Of course, only a small amount of this land (typically less than 2%) is taken up by the turbines and associated access roads.
