Colorado Renewable Energy Society – Boulder Area

Boulder County has been rated among the least energy resilience-prepared counties in the state according to a recent national study. Solar-plus-storage deployment as a complement to other energy efficiency measures represents a pivotal strategy for enhancing community energy resilience while offsetting rising grid instability and utility costs.

In Xcel Energy’s Boulder territory, average outage losses reached an estimated $7,600 for every small business in 2024—nearly 50% of the cost of a comparable backup generator or standalone battery system—amid forecasted regional rate increases of up to 55% by 2029. Using a discounted cash flow framework integrated with localized reliability statistics, our analysis indicates that an integrated 10–15 kWh solar-plus-storage system delivers superior long-term financial performance compared to gas backup or battery-only configurations. Smaller systems optimized for daily tariff arbitrage or Virtual Power Plant (VPP) enrollment maintain strong financial yields, supplemented by Vehicle-to-Building (V2B) integration for emergency redundancy.

Beyond small business commercial applications, embedding localized outage data into capital planning supports sustainable financing structures—including leases and Power Purchase Agreements (PPA)—to lower upfront capital barriers for multi-family housing and community resilience hubs as well. Ultimately, equitable distributed energy resource adoption aligns local policy objectives with ratepayer interest and grid operations by reducing local congestion, improving resiliency, and mitigating macro-level rate pressures.

We'll be joined by Steve Johnson, Senior Director, Markets Administration, of the Southwest Power Pool (SPP), to receive an update on their western expansion via their RTO and Markets + initiatives. Colorado Utilities are required by law to join an organized wholesale market by 2030, which should enhance efficiencies, lower wholesale energy costs, and provide for coordinated transmission development. It should also help better integrate renewable energy resources. Join us to learn how the market has worked as it has moved from the initial energy imbalance market to a full wholesale market (RTO) and what the future holds. More details to come.
