Utilizing Grid Connected Solar Power for Backup Systems
and Clean Power Production
Tim Kehrli, Solar Integrated
Technologies
Current technologies in photovoltaic systems have the ability
to generate and store energy for use in laboratory facilities. Previous
systems have often not been able to provide the power quality or
the storage medium was too expensive to supplant older technology
or accepted systems. The purpose of the presentation will be to
examine current PV systems from the PV to the inverter to the energy
storage methodology and demonstrate their applicability to the laboratory
environment.
Particular focus will be placed on storage technologies including
batteries, hydrogen and grid connected options, and power qualities
offered by inverter manufacturers. Current examples of installed
PV systems and costs of typical systems will also be presented.
Labs21 Connection:
Laboratories are unique facilities where power densities often
preclude renewable power systems. By utilizing various storage techniques,
renewable power can be incorporated in these facilities and add
to their green component. These power systems can also be viewed
from a power security angle as they are not dependant on grid power
and may be used as a reliable backup to grid power systems. Even
more difficult to stomach is that these systems can be cost effective
when all the environmental and opportunity costs are factored into
the equation.
Biography:
Tim Kehrli has been involved in Energy Savings
Performance Contracting (ESPC) since 1995 when he served as the
technical committee chair for DOE's first ESPC at the Hanford Nuclear
site in Richland, Washington.
Since 1996, Tim has worked as a subcontractor to the National
Renewable Energy Laboratory (NREL) providing technical and financial
support for the development and implementation of the DOE Super
ESPC program. His primary role was as a project facilitator, supporting
the development of ESPC projects for multiple agencies across the
country. He was a member of the DOE Super ESPC Workshop Training
Team and works with FEMP to continue development of additional alternative
financing opportunities.
Tim recently took on the position of Government Sales Director
for Solar Integrated Technologies. In this new role he is working
with government entities to identify opportunities for PV systems
to utilize solar energy.
Tim holds a BS in Mathematics from the University of Puget Sound
and has completed the course work for a MS in Mechanical Engineering
from the University of Minnesota.
