expertise and contribute to the region's efforts to take a wide-ranging look at
possible next steps for regional power grid development. I share the New

successes will serve us well as we evaluate future resource scenarios,"

In recent months, a team of ISO New England
engineers and economists has been analyzing more than 40 scenarios to integrate
renewables, primarily large-scale wind resources
onshore and offshore, into the region's electric grid by 2030.
Summary of Economic Study Results
The objective of this study was to evaluate a
hypothetical future power system under a number of scenarios. The study focused
primarily on wind development, but also considered other resources such as
demand resources, plug-in electric vehicles, expanded imports, and energy
storage.
Though the study did not offer specific
recommendations for resource or transmission development, key findings from the
analysis include:
-- Significant amounts of potential wind
resources could be added to
-- For all of the scenarios considered, new
transmission investment would be required to move energy from renewable
resources to consumers throughout
-- Annual wholesale electric energy prices would
be generally lower with the addition of renewable resources that have low or no
fuel costs, such as wind, or when overall electricity use is reduced, as is the
case when high levels of demand resources are added to the system.
-- Lower levels of sulfur dioxide, nitrogen
oxide, and carbon dioxide result when low-carbon-emitting-resources are added
to the system or when older fossil-fueled generators are either retired or repowered with more efficient combustion technologies. The
study assumed retired units would be replaced by new, natural gas
combined-cycle units and repowered units would become
measurably more efficient by incorporating new natural-gas fired technology
with portions of the existing unit's infrastructure.

About ISO New
As a part of its regional planning process, ISO
New England each year studies stakeholder proposals to explore opportunities
that may improve power system efficiencies and produce economic benefits. Under
study in 2009 is the request by NESCOE, acting on behalf of the governors, to
identify the economic and environmental impacts for a set of renewable
development scenarios. The states developed the study assumptions with
technical input from the ISO. The study was conducted to support the governors'
efforts to develop a renewable energy blueprint.
Created in 1997, ISO New England is the
independent, not-for-profit corporation responsible for reliably operating

Roubidoux
True tales of the Huckleberry Finn type adventures of a boy who journeys from
delinquency in California to Southern culture in the Missouri Ozarks. Although told
through the eyes of a twelve year old who never grows old, much of the real life
adventure is emotionally timeless with appeal to all ages. Brutally honest at
times but never off colored.

Do you know that your body is naturally acidic which makes you susceptible to all manner of unhealthy conditions and illnesses? By making your body alkaline instead of acidic you mitigate these potential health problems. One way of doing this is to drink alkaline water. The above machine is called the "Athena" and makes tap water into pure, clean alkaline water. It's rather expensive, but it's the best in the world. Isn't your health worth it?
