In just the last few years, the number of worldwide cellular base stations has grown from numbering in the hundred thousands to the many millions, and with this explosion in base station numbers has come with it the fear for all the greenhouse gases and pollution that powering a cellular network creates.

This report cover these two important aspects of green base stations, 1) powering base stations with solar and wind where reliable power doesn't exist and 2) reducing the energy demands of all cellular infrastructure. Five-year forecasts in this report include the number of on-grid base stations in developing regions, the number of off-grid/unreliable-grid base stations in these areas, and the number of solar, wind, and solar/wind combo base stations in these areas. Forecasts are broken out for three regions: Africa, South Asia, and Latin/South America & Caribbean.

オペレータのためにもなる太陽光と風力による'グリーン'セルラー基地局市場

アリゾナ州スコッツデール、2009年8月25日
ここ数年間で、世界のセルラー基地局の数は、数十万レベルから数百万レベルへと爆発的に増加したが、それらに必要となる電力は多くの地球温暖化ガスと環境汚染を生み出していると、米国調査会社インスタット社は報告する。実際、オングリッドの基地局は大して問題ではないが、携帯電話が新興国の何十億の人々に普及するようになると、オフグリッドの基地局(通常、年中無休24時間のディーゼル発電)が増加することになる。

「ディーゼル汚染は環境問題であるが、オペレータを最も苦しめるのは、発電機を動かし続ける費用である。トラックで遠隔地までディーゼル燃料を運ばなければならず、また、オペレータはディーゼル燃料と設備の窃盗に何百万ドルをも費やすことになる。解決策は、オペレータが風力タービンかソーラーパネル、またはその両方で遠隔地の基地局を少なくとも部分的に動かすことである。まさに、グリーンであり、得にもなる」とインスタット社のアナリストAllen Nogee氏は語る。

インスタット社は、下記についても調査した。

• 2014年までには、発展途上国のセルラー基地局の23万以上が、風力か太陽光発電の動力を備えているだろう
• オフグリッドの基地局は、年間30％増加するだろう
• オフグリッドの基地局は、アフリカやインドなどの南アジア、南米、ラテンアメリカ、カリブ海諸国に主に普及するだろう

インスタット社の調査レポート「グリーン基地局:現実化する携帯電話インフラの再生可能エネルギー採用 - Green Base Stations: Renewable Energy Becomes a Reality in Cellular」は、世界の発展市場のセルラー基地局市場の技術を調査している。太陽光と風力による基地局の2014年までの市場予測、グリーン基地局技術のコストや利点などの分析、Huawei、日本電気、Nokia Siemens、Ericsson、Alcatel-Lucentの最新のグリーン基地局向けの技術開発について記載している。

Solar, Wind Power Enable ‘Green’ Cell Base Station Market; For Operators, it Pays to be Green

SCOTTSDALE, Ariz., August 25, 2009 - In the last few years, the number of worldwide cellular base stations has exploded from the hundreds of thousands to the many millions, creating greenhouse gases and pollution from the power required to run them, reports In-Stat. Base stations on an electric grid aren’t the real problem, but as cellular spreads to billions of people in emerging countries, off-grid base stations, which are usually powered by diesel generators running 24/7, proliferate.

“While diesel pollution is an environmental issue, what bothers operators the most is the cost of powering and securing the generators,” says Allen Nogee, In-Stat analyst. “Diesel fuel has to be trucked to remote sites, and theft of diesel fuel and equipment can cost operators millions of dollars. The solution is for operators to at least partially power remote base stations with wind turbines, solar panels, or both. This is truly a case where it pays to be green.”

Recent research by In-Stat found the following:

• By 2014, over 230,000 cellular base stations in developing countries will be solar-powered or wind-powered.
  
• The number of off-grid base stations is growing at 30% per year.
  
• Off-grid base stations are primarily located in Africa, South Asia (including India), South America, Latin America, and the Caribbean.

Recent In-Stat research, Green Base Stations: Renewable Energy Becomes a Reality in Cellular Infrastructure (#IN0904369GW), covers the market for cellular base station technology in the developing world. It includes:

• Forecasts of deployed solar- and wind-powered base stations through 2014.
• Analysis of green base station technology including costs and benefits.
• Recent green base station technology developments by Huawei, NEC, Nokia Siemens, Ericsson, and Alcatel-Lucent.
