I am delighted to present to you Power Engineering International’s 2012 Buyers Guide, which we hope will once again prove an invaluable tool for making the right plant equipment and services purchasing decisions – a key objective in these economically challenging times.

Over the last 12 months we have been working hard to compile the most accurate and up-to-date product and services information and company listings through our questionnaires and telephone research. But if you spot any errors or omissions, please contact us at peibg@pennwell.com so that we can continue to strengthen the information we provide.

The Buyers Guide is divided once again into three main sections: a Products listing, a Services listing, and a company directory featuring full contact details. The guide’s Index can be found at p.22–25.

In the Products and Services sections, which extend from p.26 to p.47, you will find an extensive, although not exhaustive, list of companies that serve the global power industry, with each company listed under the relevant product or service heading and subheading.

Power Engineering International’s annual Buyers Guide highlights companies involved in all forms of electricity generation – from coal and gas fired power plants to the latest wind and solar power facilities, and from large-scale hydroelectricity to nuclear power – as well as companies serving the T&D sector.

The alphabetical company directory from p.48 lists full mailing addresses and contact details such as telephone numbers, email addresses and website URLs, if supplied.

This issue also features three interesting and diverse articles.

The potential for generating clean, green electricity from the world’s marine resources – i.e. tides and waves – is undoubtedly huge, but the conversion technologies remain in their infancy and much investment and development work is still required to bring them to market. However, the impetus behind this sector is speeding up, particularly in Europe and especially in the UK. Penny Hitchin, starting on p.2, profiles some of the marine energy conversion technologies that may evolve into the ultimate market leaders, setting industry standards and providing mainstay generation in the future.

We also chart in this issue the transformation of circulating fluidised bed (CFB) technology from robust small-scale industrial boilers for burning difficult fuels into a highly competitive option for large-scale utility applications – not only are there 800 MW boiler designs available, but CFB has also gone ultra-supercritical (p.16–21).

As the momentum to smarten up our energy system picks up, a host of experts in this field explain why smart meter roll-outs and the creation of Smart Grids will only ultimately be successful if utilities and governments focus on getting the backing of consumers (p.10–15).

I very much hope you find this year’s Buyers Guide useful and I wish you a successful and prosperous 2012.

Kind regards,
