LPC's Renewable Energy Program
Longmont 's renewable energy is purchased from Platte River Power Authority, our wholesale electricity provider. Platte River acquires renewable energy from a variety of sources, including:
• Wind energy generated at the Medicine Bow (Wyoming) Wind Project, owned and operated by Platte River
• Wind energy generated at the Silver Sage (Wyoming) Wind Project, owned and operated by Platte River
• Renewable energy produced by Platte River resources combined with Renewable Energy Certificates (RECs) from wind and landfill gas facilities owned by other utilities
RECs represent the legal right to the environmental benefits associated with replacing one megawatt-hour of energy on the electricity grid (most of which comes from coal and gas in the Rocky Mountain region) with one megawatt-hour of renewable energy.
LPC's voluntary renewable energy is Green-e certified - the energy purchased meets specific environmental and consumer protection standards established by the Center for Resource Solutions.
Renewable energy costs more to generate than traditional sources - about 2.38¢ per kWh. This cost is added to the utility bills of Longmont residents who choose to purchase renewable energy.
Where LPC's power comes from
In addition to producing a small portion of electric power from LPC's historic Hydroelectric Plant near Lyons, Colorado, LPC purchases electricity from Platte River Power Authority. The charts below show that power mix, which includes a growing portion of renewable energy:

Sign up for renewable energy
When subscribing for renewable energy, the premium renewable rate is added to the regular electricity rate and will be added to the customer's monthly utility bill. By providing the following information and submitting it to LPC, the customer agrees to
make a one-year commitment to purchase renewable energy. LPC will begin charging
your City of Longmont utility bill one month after renewable energy becomes available
for purchase. LPC will notify the customer prior to the renewable energy charges being
applied to their bill.
*While a City of Longmont Utility account number is not required to process subscriptions, it will speed the process for customer service representatives. Customers can locate their account number on their utility bill.
