Garbage In, Power Out: How Trash Can Power Ethanol Plants

A win-win situation for the local government, utilities, and industry.

Ethanol plants either are operating, under construction, or planned for several areas in the Midwest. These same areas also have municipal solid waste (MSW) produced daily in an existing landfill. In addition, these areas have a need for establishing or extending a landfill.

As an alternative to the existing concept of a landfill, plasma-arc technology has been applied to the treatment of MSW. Known as plasma-arc gasification for the treatment of MSW, this recent development would eliminate or minimize the need for a landfill.

Don't Mess With Texas

America’s energy competition laboratory prepares to build.

The ERCOT region remains a living example of how to make a successful transition to restructured wholesale and retail markets for electricity. At the same time, the market continues to witness some significant developments. Sights are turning from recovery to the next stage of the power business cycle: The Buildup.

America's Resource Mix

Wind gains, but won’t soon alter the fuel mix.

Some power markets may be seeing possible signs of recovery. Spark spreads appear to have bottomed out, and reserve margins have begun to fall in some markets. As Figure 1 shows, recovery is uneven, with many regions still experiencing excess supply and a few regions with peak reserves under 10 percent.

Synchronizing on West Point

Could local generators be used either to regulate voltage or control the power factor on distribution systems in New York?

Reactive power is becoming a hot issue in many regions of the country. Regulators and grid operators are grappling with ways to account fairly for reactive power supplies, and to encourage such resources to come online where they are needed. These analyses, however, are largely ignoring a vast fleet of infrastructure already installed on the network. West Point military academy, for example, has four small synchronous generators that are used for combined heat and power or emergency power applications. If these generators also were used as synchronous condensers, they might supply additional revenue to pay for the distributed energy investment.

BGS Auctions: What Price Is Right?

How to price new load-servicing contracts while incorporating market-risk analysis into such deals.

Why have basic generation service auctions historically been overly competitive given the prevailing market prices at the time? Here are four steps to determine correctly what should the bid price should be.

Building a Better Utility

Many of the obstacles and strategic issues that utilities face today are all too familiar. This time they must be solved with a different business model.

We overbuild, run short, then overbuild again. You'd think we'd learn, because when the forecasts aren't accurate, when overcapacity plagues the industry, companies fail. Can we get the forecasts right? Probably not. But we can plan for forecasts that will be wrong. They always are. And they will be until the system is redesigned to let prices clear the market.

Closing the Green Gap

Will wind power close the gap between state renewable portfolio standards and the current shortfall in viable technologies?

Renewable portfolio standards or mandatory renewable quotas have been established in 20 states and formally considered in 6 more. There is currently an energy shortfall of 118,400 GWh between operating non-hydro renewable electric output today and that required in 2020. Many state and local regulatory agencies have begun to work together to overcome many of the historic barriers to renewables development, such as transmission constraints, permitting, tax policy, and trading. It's clear that they will have to if renewable energy technologies are ever to meet state renewable portfolio standards.
