Wisconsin's largest electric utility says that it will ask permission to build a 50-megawatt wood-burning power plant that would go into operation in 2013. It is part of the state's renewable energy mandate and it would be the third such biomass facility announced there this year in what could become a trend in certain regions.

Wood-burning power plants have some key advantages over types of renewable energy programs and namely that such generators are not subject to the whims of the weather -- that they can remain running as long as the wood gets shoveled into the furnace. And in many parts of the nation, such agricultural products are abundant.

It's taken five years. But the Public Service Commission of Wisconsin has given approval to American Transmission Co. to build a new 32-mile high voltage transmission line that will link two towns within the state and which will be complete by 2013. While obscure to most of the nation, the $215 million project may represent a gradual shift in how transmission is owned and permitted.

The demand for energy is expected to keep climbing and contributing value to most power facilities. In states that have restructured their electricity markets, that energy can be sold at market rates, giving well-run facilities the chance to earn superior returns. Transmission systems, however, will continue to be regulated, perhaps making the investments less attractive to certain utilities and more appealing to third party transmission owners.

The regulatory and financial maze surrounding the construction of new nuclear plants might be circumvented if some developers are able to commercialize smaller, less controversial reactors. Such efficient units could be built and shipped at a fraction of the time and money than the much bigger base-load facilities.

The focus is now on right-sized reactors that are typically between 100 megawatts and 300 megawatts. They would be mostly marketed to developing nations where the transmission grids cannot handle the larger, 1,000-3,000 megawatt systems. And while the concept may sound appealing, researchers must still prove that idea is doable. Once the projects are shown to be feasible, developers can then take the various components of the smaller facilities and use them to form base-load plants.

Below are a few letters received at EnergyBiz Insider on topics that appeared in the past few weeks. They capture the essence of how many readers say they feel.

Solar panels have never been cheaper. But that development may not be welcome news for the industry unless it is able to sell more units.

While it's all generally good for consumers who will see the cost of installing solar at their homes fall dramatically, it's potentially troubling for solar manufacturers that have excess inventories. Altogether, solar system installation prices have dropped by 50 percent from a year ago and mostly because of unsold systems.
