RE: 100% Renewable Option for Electricity Supply
This memo is in response to Mayor Pro Tem Horak's request at the April 17 Leadership Planning
Team meeting for staff to consider the timeframe and costs involved with a 100% renewable
option for electricity supply.
BOTTOM LINE:
The potential costs and benefits of large renewable energy supply additions will be better
understood when the Platte River Power Authority Customized Resource Portfolio modeling
results are available at the end of 2017.
BACKGROUND:
City Utilities staff has been working with Platte River Power Authority on a Customized
Resource Portfolio (CRP) modeling effort since 2016.

The CRP model inputs include a range of renewable wind and solar supply additions and will
test price sensitivities including the potential of participating in an organized energy market.
One model run includes a renewable scenario with 200 megawatts (MW) of wind turbine
generation and 100 MW of utility scale solar photovoltaic additions to the existing portfolio.
Preliminary assessments indicate this specific case could create a 75% renewable energy supply

portfolio for Fort Collins based on total energy delivered. This scenario considers existing
hydropower, existing wind and solar contracts, and renewable energy credits.
This high penetration renewable scenario was chosen to model a path that could achieve the Fort
Collins Climate Action Plan Framework 2030 goal of 80% carbon reduction over the 2005
baseline. If this model is feasible, a future model run to explore a 100% renewable scenario
could be explored in partnership with Platte River.
The timing on implementing a customized portfolio is uncertain. It will first depend on building
a financial and operational business case in 2017-2018, and then is dependent on acquiring the
new supply resources.
