WinpowerWest
MREA’s Vision for NorthWestern Energy (2025)Revenue decoupling, efficiency and distributed energy resource standards, participation in a west-wide energy imbalance market, and a clear price on greenhouse gas emissions have provided NWE the regulatory certainty and price signals to aggressively deploy efficiency, renewable energy and storage resources.
• NWE operates 50 MW of community solar projects that allow customers to lower their energy bills with subscriptions to the projects. NWE prioritizes and incentivizes participation of low-income customers.
• Utility and customer-owned on-site solar provide 2% of NWE electricity sales. Advanced inverter standards maximize the potential grid benefits of distributed energy resources.
• NWE is investing heavily in demand response and energy efficiency, including low-income residential projects, leading to lower customer bills.
• Utility-scale storage, utility-integrated distributed storage, and upgrades at NWE-owned hydros have reduced integration costs for new wind and solar supplies while improving grid reliability.
• A statewide network of public and private electric vehicle charging stations with incentives for providing grid support services via vehicle batteries has triggered a significant transition of vehicles to electric power.
• Time of use, inclining block, and minimum bill tariffs incentivize efficient energy use and lower peak demand while ensuring customer equity.

Supportive of policy changes
that will protect our environment
Greater support for
low-income Montanans
Sees their role as one of the nation’s pioneering innovative utilities:
Leading MT into the energy future, rather than clinging to the past
Keeps a dynamic energy economy in mind when

Two customized pilots
Based on Stakeholder input
Meeting customer needs

Guiding Principles
Reformative
• Changes how the customer and utility interact
• Educates key stakeholders
• Requires that the project is replicable
Measurable• The outputs are credible, unbiased, actionable,
relevant, and there is a timeline for goal tracking
Sustainable
• Can be adapted for different environments
• Beneficial to the triple bottom line (environmental, economic, & social)
• Considers future customer needs along with current customers
Equitable• All parties are considered and no costs are
transferred to nonparticipants
• Program can be justified to nonparticipants
14
Pilot Concept 1:Community Solar with Low Income Carve-Out
•A central station solar project is developed and the
output assigned to participants–Participation open to residential customers and, potentially, some commercial & industrial
–Specific low income participation targets
•Participants pay a set amount, either in a fixed up front
payment or a fixed cents per kWh rate; in return, they
receive their share of system output
15
Community SolarLow Income Community Solar
16
Pilot Concept 1:Group Activity Support
Pilot Concept 2:Utility-Owned Rooftop PV w/ Smart Inverters
•NWE invests in and installs rooftop solar projects for a
small number of residential customers; as part of this
deployment, NWE would also install and test advanced
inverter functionality
•Customers would receive the benefits of the solar
resource via some form of economic transaction (ex: roof
lease bill credit, fixed bill, etc.)
•NWE could target grid-beneficial installations, such as
west-facing systems, or targeted locations on the grid
that would benefit from local generation
17
Smart InvertersRooftop Solar (Utility-owned)

Pilot Concept 2:Group Activity Support
Pilot Concept 3:New TOU Rate for Solar Customers
•A new rate would be developed for solar DG customers,
where the time-of-use windows align better with solar
production
•Could be paired with an AMI (or AMI-like) metering
solution
19
Pilot Concept 3:Group Activity Support
TOU Rate Design for Solar
20
Pilot Concept 4:EV Charging Station Deployment
•NWE would install a network of EV charging stations at
key locations across the Montana service territory
•Deployment would include both Level II and DC Fast
Chargers
21
Pilot Concept 4:Group Activity Support
EV Charging
22
Pilot Concept 5:
Rural Reliability Pilot
•NWE would identify a rural feeder / city that could be
bolstered by strategic deployments of solar, storage, and
related technologies
•The goal of this initiative would be to both increase local
system reliability, while also determining the ability of
these technologies to defer other more traditional utility
infrastructure investments

Pilot Concept 5:Group Activity Support
Pilot Concept 6:Holistic Schools Program
•One or more schools are targeted for the deployment of
a holistic package of energy-related technologies /
programs–Solar, storage, time-of-use, energy efficiency, etc.
•Education content around energy consumption is
developed in partnership with the host school
