More solar and other renewable-energy companies are planning initial public offerings, despite the lackluster performance of some recent entrants into the public market. 

Edisun Power, Jiangsu Shunda Group and Changing World Technologies last week became the latest to announce plans to go public.

Renewable-energy companies haven't fared well in their public-market debuts so far this year. Investors pummeled GT Solar's stock on its first and second day on the Nasdaq last month (see GT Solar Goes Public, GT Solar Sinks on LDK News and GT Solar IPO Attracts Class-Action Suits).

EDP Renovaveis, a Portuguese renewable-energy firm, also saw its stock drop on the first stock on the Euronex Lisbon exchange in June (see EDP Renovaveis Gets No Love).

Since then, more companies have filed for IPOs, including A123Systems, a developer of lithium-ion car batteries (see A123Systems Files for $175M IPO and Funding Roundup: More IPOs for Wind, Solar).

Swiss solar-power project developer Edisun Power aims to raise up to $69 million through an IPO on the Swiss Stock Exchange, reported New Energy Finance (via Clean Edge).

Edisun Power already has developed projects in its home country as well as in Germany, Spain and France. The company plans to use the new capital to expand its business in those countries.

Changing World Technologies, which makes organic fertilizers and biodiesel in West Hempstead, N.Y., has filed paperwork to raise up to $100 million in its IPO.

The company hasn't yet set a range of expected offering prices. Changing World generated $589,000 in revenue last year, more than double the $261,000 in revenue from 2006, according to filings with the U.S. Securities and Exchange Commission. Changing World posted a loss of $19.9 million in 2007 and a loss of $21.76 million in 2006.

Meanwhile, Jiangsu Shunda Group isn't planning its IPO until the first half of 2009, but already has set a fund-raising target and plans for spending the money. The maker of silicon ingots and wafers is aiming to raise $1 billion in a debut on a U.S. stock exchange to fund "rapid expansion," the company told Reuters.

The Chinese company's customers include Suntech Power, which owns 15 percent of Jiangsu Shunda, as well as Q-Cells and Sharp. Jiangsu Shunda initially had planned to go public last year, but decided to wait for its first polysilicon plant to be completed and for confirmation about whether the plant meets global standards.
