Energy and exchange rate (Brazil) Investments in the production chain of the electricity sector are strongly linked to the Dollar. Historically, they are referred to as Dollar/GW installed in generation, transmission and distribution. Thus, the cost incurred in delivering energy to consumers – industrial, commercial, institutional and residential – is linked to the Dollar. The..

Announcing yet another lag beyond a new in-service date for its Kemper County integrated gasification combined cycle (IGCC) project, Southern Co. may raise discussions with regulators about the possibility of scrapping the project’s gasification component.
The company’s subsidiary Mississippi Power last said the first-of-its-kind project should begin operations by May 31. On May 31, however, the utility announced that the facility “is not currently fully operational.” It also said it would delay a monthly project status report that was due on June 1 to the Mississippi Public Service Commission (MPSC). It plans to submit the report on June 5 instead, because “the company continues to assess the project’s schedule and cost.”
On June 5, the company is also likely to make a rate filing for the project. It is expected to request an accounting order to defer all costs incurred after the project is operational, that are not subject to a cost cap, and are not already included in rates.
Mississippi law allows Mississippi Power to file both a traditional rate case and an alternative multi-year rate mitigation plan.…
Power plants are familiar with using continuous emissions monitoring systems (CEMS) to monitor pollutants, but these devices also may be able to measure heat rate—which could be handy for future compliance with the Clean Power Plan.
Continuous emissions monitoring systems (CEMS) are used to monitor power plant flue gas emissions as a means to comply with federal and state air emission standards. Through various methods, they determine the concentration and amount of key emissions, including nitrogen oxides, sulfur dioxide, carbon monoxide, carbon dioxide (CO2), hydrogen chloride, particulate matter, mercury, and volatile organic compounds (Figure 1).

CEMS are required in all U.S. fossil-fired plants greater than 25 MW. They are a mature technology, and most have been widely used for more than 20 years.
The CEMS data provides an official record of the key power plant flue gas emissions. In the U.S., this data is reported to the Environmental Protection Agency (EPA).…
