On-site generation & storage
Demand charges can run to 30–70% of a commercial electric bill; an NREL survey of over 10,000 commercial tariffs puts numbers behind what facilities managers already see each month. Rooftops, carports, and owned land are supply you already control. Whether a system sized against your load profile and your tariff clears your hurdle rate is an underwriting question, and the answer should come from an independent advisor.
What we do
Sized against the load profile and the tariff.
Feasibility & siting
Screen the roof, the parking field, and the ground for structural, interconnection, and utilization constraints; establish what each site can physically and contractually host before anyone prices it.
Tariff & bill analysis
Decompose the bill into energy, demand, and fixed components; identify which charges generation can address, which require storage dispatch, and which no on-site system will touch.
System sizing
Size solar and storage against interval data instead of the available area; the increment of capacity that pays is usually smaller than the increment that fits.
Structure selection
Own the system or buy its output: direct ownership, on-site PPA, or lease, compared on balance-sheet treatment, tax-credit eligibility, and who carries performance risk. We frame the comparison; your tax and accounting advisors conclude on treatment.
Procurement
A competitive RFP to qualified developers and EPCs, with bids normalized to the same system boundary, production estimate, and warranty terms so the comparison is real.
Negotiation & execution
Contract terms that survive decades on your site: performance guarantees, O&M scope, insurance, decommissioning, and an interconnection and permitting calendar with named owners.
Who it's for
Owners of load, roofs, and land.
- Corporates & data centers adding on-site and distribution-connected supply for speed to power, resilience, or relief from demand charges.
- Industrials with process load, high demand charges, and roof or yard space that currently earns nothing.
- Public sector agencies turning rooftops, carports, and owned land into lower-cost, carbon-free supply through a procurement-compliant process.
Worked example
Why solar alone can miss the demand charge.
Demand charges bill the single highest draw in the billing period, measured over one short interval. A solar array reduces energy charges whenever it produces; if the billing peak lands after sunset, or during one overcast afternoon, the demand charge survives untouched. On tariffs where that charge runs toward the top of the 30–70% range, an array sized to the roof can leave most of the bill in place.
Storage addresses the demand component only if it is dispatched against the billing peak, which means the tariff, the interval data, and a dispatch strategy belong in the model from the start. Sized that way, a smaller array paired with a correctly dispatched battery can outperform a larger array standing alone; the comparison is mechanical, and we run it on your own interval data before you commit any capital.

30 minutes on your sites, your tariff, and whether the analysis is worth running; a recent bill is useful but not required.
