With rising utility rates and persistent grid congestion, US commercial and industrial (C&I) users are increasingly adopting onsite solar and battery storage as a defense against volatile energy prices. Onyx Renewables CEO Mary Beth Mandanas highlights how these distributed assets deliver fixed power pricing for terms up to 25 years, lowering exposure to fuel-driven cost swings and accelerating deployment compared to centralized grid power solutions.
Key figures
20-to-25-year fixed onsite solar PPAs
Grid-supplied power pricing tied to natural gas
Multi-year interconnection queues
Price volatility and grid pressure
C&I energy customers are grappling with increasing utility bills and expansion in grid transmission fees, a scenario exacerbated by natural gas price volatility and congested interconnection queues. This dynamic places a premium on solutions that address both cost predictability and operational flexibility. The marginal price for grid power is often set by natural gas generation, transmitting every uptick in fuel cost directly to businesses’ bottom lines.
Meanwhile, long interconnection queues, now measured in years for some regions, increase risks and timelines for new grid-tied projects, restricting the ability of businesses to access new supplies quickly. These headwinds are accelerating the search for more rapid and predictable energy procurement models that sidestep constraints endemic to the central grid.
Onsite generation as an energy hedge
Onsite solar paired with batteries enables C&I customers to isolate their energy costs from swings in fuel prices. Onyx Renewables notes that solar’s zero-fuel input preserves price stability, offering fixed rates for electricity through long-term contracts. These agreements, typically lasting 20 to 25 years, function as a fixed-to-floating energy swap for the portion of power supplied onsite, reducing reliance on grid-delivered electricity sensitive to commodity markets.
The firm’s distributed generation projects give buyers a physical hedge, meaning that the energy component delivered from onsite systems is not affected by sudden changes in gas prices. Instead, businesses can accurately forecast operating costs linked to their power procurement, a significant benefit as utility prices rise unpredictably year over year.
Operational value: Peak shaving and speed
Beyond pure price arbitrage, pairing onsite solar with battery storage allows users to optimize how and when they consume grid power. Load shifting is possible by storing energy generated during off-peak times and discharging it during high-tariff periods, thereby reducing peak demand charges and shaving exposure during the most expensive intervals.
These distributed assets are also deployable on much faster timelines than large-scale grid projects stalled in congested interconnection queues. For commercial real estate and data center operators pressured by near-term deployment schedules, solar-plus-storage adds vital speed to power, enabling expansion or new builds even when utility connection is delayed.
Third-party ownership and financing
The capital intensity of onsite solar and battery systems is often addressed through third-party ownership models. Project developers such as Onyx Renewables finance, build, and operate these systems on C&I properties, offering energy savings without the buyer having to outlay upfront capital. Customers enter power purchase agreements with a specified price per kilowatt hour for the long-term output of the onsite assets.
In effect, these structures offload technical and operational risks from the commercial user to the energy developer, enabling broader adoption, especially in capital-constrained segments. This also aligns incentives for long-term asset reliability and performance, as the project owner must deliver contracted energy volumes over the life of the agreement.
Market significance and adoption outlook
The move toward distributed generation via onsite assets is gaining momentum as grid congestion, transmission fee increases, and fuel price volatility show no signs of abating. For institutional investors and C&I developers, these trends imply a rising premium on distributed energy solutions capable of bypassing central bottlenecks and delivering faster speed-to-power outcomes.
This shift is already manifest in growing deployments of commercial-scale solar and battery projects under long-term contracts configured to optimize savings and protect against market swings. As more organizations adopt these models, expectations for cost reductions, grid resilience, and deployment certainty will likely rise, reinforcing investment in the distributed energy sector across the next several years.
What this means for buyers
Power and energy storage assets in US commercial and industrial real estate are directly affected. The ability to secure 20-to-25-year fixed pricing for onsite generation enables buyers to hedge utility costs and avoid delays from interconnection backlogs. Decision makers can now accelerate facility launches and control energy budgets by evaluating distributed solar-and-storage agreements rather than waiting on the grid.
