Green Energy

Purchase Clean, Renewable Energy

Purchase Clean, Renewable Energy

Residents and businesses in Fort Collins can purchase clean, renewable energy for an additional 1.9 cents per kilowatt-hour (kWh) on top of their normal utility bill.*

All customers may purchase 100% of their energy use or as many blocks as they need.

  • Residential customers can purchase blocks of 200 kilowatt-hours (kWh) for $3.80 per block
  • Non-residential customers can purchase blocks of 1,000 kilowatt-hours (kWh) for $19 per block

Subscribing to the Green Energy program means that you can legitimately claim that your home or business is powered from renewable energy. In the current Green Energy program, the additional charge is paying for the price premium through a renewable energy tariff with Platte River Power Authority.

The structure will change in 2021 with expected revisions to wholesale tariffs and with two new renewable energy projects coming online (Roundhouse wind and Rawhide Prairie solar). Utilities will revise the Green Energy program to provide a mix of wind/solar and a new pricing structure. While the claim to renewable power will remain the same, Utilities expects to include a portion of the subscription to invest in the local distribution system in order to eventually reach 100% renewable electricity.

As of 2020, the resource mix for the Green Energy Program is 100% Colorado wind.

Why do we have Green Energy?

Utilities is a member owner of Platte River Power Authority, a joint-action agency that supplies nearly all of the electricity to Fort Collins customers. Platte River supplements its own resources with purchases from the regional electric grid. In addition, locally-generated solar electricity also supplies customers with a portion of their use.

Key principles regarding the attribution of non-fossil resources in Fort Collins include:

  • Utilities 100% Renewable Electricity Resolution (2018-094) defined renewable electricity to include non-fossil sources, including wind, solar, hydroelectricity, geothermal and other means that may become available that do not add greenhouse gases to the atmosphere.
  • Utilities self-certifies compliance with the Colorado Renewable Energy Standard and has exceeded the minimum requirement since the standard was created.
  • Renewable resources that are included in the voluntary Green Energy Program are dedicated to the group of customer-subscribers and do not accrue to non-participating customers.
  • Electric customers can attribute the fraction of renewable electricity in the general resource mix for their facility according to their purchases of electricity from Utilities.


What is the price comparison between Green Energy and the normal resource mix over the years?

The residential rates are designed to cover the cost of service for the residential class of customers. The Green Energy Program price is a premium on top of the residential rate and has been set at the cost of a specific renewable energy tariff from Platte River. View the table below to see how the rates have changed since 2010. This last value may be most relevant, as we anticipate the percentage premium for renewable electricity to generally decrease over time.

What are renewable energy credits/certificates (RECs)?

All renewable electricity sources create renewable energy credits/certificates (RECs). RECs are the mechanism by which the renewable attributes are documented for electricity, which is otherwise undistinguished from other sources.

RECs from owned or contracted renewable resources are tracked and held on behalf of the communities and/or customers. RECs may be tracked in third-party administered systems (e.g. Western Renewable Generation Information System, WREGIS) or via bilateral contracts between seller and buyer (e.g., via local solar interconnection agreements).

What are alternatives to the Green Energy Program?

If you wish to offset your usage and decrease your utility bill while using a renewable source, we recommend looking to installing a solar photovoltaic (PV) system on your home.

Utilities supports customers generating their own renewable energy using solar PV panels. The Solar Rebate Program provides incentives and guidance to help make sure each project is a success.

2018 Electricity Resource Summary

*This price is subject to change. As required by City Charter and City Code A 6% PILOT (payment in lieu of taxes) has been added to electric, green energy, water and wastewater rates. This is a payment to the City’s general fund to replace revenue the City would receive from the Utilities in taxes and franchise fees if the utilities were privately owned. Without PILOTs, the Green Energy Program rate is 1.79 cents per kWh.

Disclaimer: Green Energy charges are calculated based on "kWh used." Net meter customers may have additional excess kWh generated that are not included in this calculation.
