Lessons learned Critical issues in terms of the
power output and response time.
Major development
trends
Unresolved issues
American Superconductor has
several units in the field at this
time. However, they have
standardized on the D-SMES
installation as the standard
product. At present there is only
one developer.
Costs of SMES units relative to
other PQ technologies.
Early data indicates that D-SMES
is effective in the Wisconsin
application. Additional
information is required on these
and other installations.
American Superconductor is
prepared to deliver additional units
and is actively searching for
customers
Cost effectiveness of this
application compared to other
solutions.
Long-term development and
societal commitment is required
for large systems that cost over a
billion dollars and take more than
ten years to complete.
