How on-site energy becomes an operational and financial strategy.

Commercial solar can reduce the electricity a site purchases from the utility when generation aligns with its load. Its value may come from avoided energy charges, reduced exposure to future utility-price increases, available incentives, depreciation, or other project-specific economics. The outcome depends on the utility tariff, operating schedule, site conditions, ownership structure, and how the facility uses power over time.

Battery storage can make sense when a site has significant demand charges, outage exposure, time-based utility rates, operational constraints, or a need to manage how and when it uses electricity. The economics depend on the tariff, load profile, battery size and duration, dispatch strategy, incentives, financing, and the value the organization places on resilience.

Power describes how quickly a battery can charge or discharge, typically measured in kilowatts or megawatts. Capacity describes how much energy it can store, typically measured in kilowatt-hours or megawatt-hours. Duration is the relationship between the two: a 1 MW battery with 4 MWh of capacity is generally described as a four-hour system. The right balance depends on whether the project is intended to manage short peaks, support resilience, shift energy over longer periods, or serve another operating need.

Demand charges are based on a facility’s highest level of power use during a billing period, rather than total electricity consumption alone. Solar can help reduce utility purchases when it produces during high-load periods, while storage can be dispatched to reduce short-lived peaks. Understanding when a site peaks — and how its utility measures demand — is often central to evaluating the value of solar, storage, or both.

A useful early review typically includes the utility tariff, historical bills, interval load data where available, roof or land capacity, electrical infrastructure, interconnection conditions, outage exposure, incentives, future load changes, and preferred ownership or financing approach. The objective is not simply to identify equipment, but to determine whether a project fits the site’s operational and financial reality.

Projects may be structured through direct ownership, loans, leases, power-purchase agreements, or other third-party ownership arrangements. Each approach allocates upfront capital, operating responsibility, incentives, tax benefits, and long-term project risk differently. The appropriate structure depends on the organization’s objectives, financial profile, risk tolerance, and ability to use available incentives; organizations should review tax and accounting implications with their own advisors.
