Solar Savings and Opportunities for Kane County
A.
Progressive Energy Group Mgr. Arnie Schramel provided information on the
electric spend estimates, and green attributes for Kane County's Solar Field at
the Judicial Center. The projected cost for the solar fields to produce energy is
$4M. Schramel explained the transmission and capacity aspects of solar energy.
Schramel noted that transmission capacity is crucial for integrating solar into the
broader electricity grid, especially as solar's share of the energy mix increases.
He indicated that with electricity prices increasing, the cost savings of solar
energy will benefit the county in the long run. Schramel reviewed the average
annual electric load growths. Currant forecasts anticipate 3% growth which
would mean six times the planning and construction of new generation and
transmission capacity. Schramel provided information on the solar opportunities
for residents, businesses, and governmental. Incentives will pay for 50%-65% of
the solar project for residents. The payback for installing solar on rooftops for
residents is almost always less than 7 years. Purchase Price Agreements (PPA)
and Lease Arrangements are available to allow residents to have solar with no
upfront money. For business, governmental and non-profit organizations, the
payback on solar is less than 5 years. Schramel stated that Progressive
Business Solutions is currently working with Kane County to combine ComEd
accounts into a bid package for Community Solar subscriptions for the County.
These five to ten megawatt fields are available to residents and businesses who
are unable to install solar on their property. The savings are guaranteed to be
10%-15% less than the ComEd Energy Supply rate. With these subscriptions, it
is projected that Kane County could save $100K per year. Schramel addressed
questions and comments from the Committee. Much discussion ensued.
Cost Savings for Clean Energy
B.
Sustainability Mgr. Hinshaw provided information on the electricity cost savings
for the parking lot lights at the Judicial Center, the newly installed heating,
ventilation, and air conditioning (HVAC) systems. She also provided an update
on the electrical vehicle and charging infrastructure rebates. The total cost of the
indoor and outdoor lights at the Judicial Center was $2M. The cost of the
parking lot lights was $233K. There were a total of 275 lights replaced, 182K
kilowatts were removed, and a total of $21K in annual cost savings. Additionally,
7 new rooftop HVAC units were replaced in the County Court and Jail. She
explained the Seasonal, Energy, Efficiency, and rating (SEER) for the new
systems. The potential savings for the new HVAC systems will be $33K over a
fifteen year period. More accurate savings will be provided after installation.
Lastly, Hinshaw stated that clean energy tax credits were applied for two fully
electric cargo vans, and two hybrids, as well as a new charger and
infrastructure. The ComEd rebates have been distributed, and tax credits were
submitted and accepted by the Internal Revenue Service (IRS). The total cost
savings was $59K, which resulted in a 26% return. Hinshaw addressed
questions and comments from the Committee. Further discussion took place.
