VPP & grid services

Let the asset earn while it sits there.

A battery that only waits for outages is underused. Grid programs pay for flexibility — if the enrollment, dispatch limits and terms are understood before you sign.

Get Started

01What we offer

Every structure.One comparison.

Program Evaluation

Which programs your utility and market actually offer, and what they pay.

VPP Enrollment

Enrollment handled end to end, with dispatch limits in writing.

Demand Response

Curtailment and event participation structured around your operations.

Grid Services

Frequency, capacity and ancillary participation where the asset qualifies.

Fleet Coordination

Multi-site portfolios aggregated and managed as one position.

Performance Review

Event history and payments reconciled against the program terms.

02How we approach it

Analysis first. Always.

Program economics are presented as ranges with the terms attached — never as a headline number.
Dispatch exposure is disclosed before enrollment, including how often the asset can be called.
Enrollment is optional on every project. It is an upside, not a condition.

Representative engagements

Illustrative examples, not customer testimonials.

Residential rooftop + storage

A household on a new time-of-use rate, with a summer bill spike and two outages last year.

Evaluates: Twelve months of billed usage, the rate schedule, roof condition, and how much load is shiftable.
Structures: Cash ownership, financed ownership, or a third-party owned PPA — with and without storage.
Decision logic: Usually turns on tax appetite and time in the home. An aging roof may mean re-roof first.
Why it fits: Storage sized to the loads that matter, with any incentives confirmed during analysis.

Illustrative exampleSacramento, CA

Commercial rooftop

A distribution facility with rising demand charges and three proposals in three different formats.

Evaluates: Proposals normalized to one set of assumptions, then interval data, roof condition and lease term.
Structures: Direct ownership, financed ownership, a PPA, or tax-advantaged structures where usable.
Decision logic: Capital allocation decides it: asset on the balance sheet, or cost in operating expense.
Why it fits: If the roof outlives less than the system, the sequence — not the system — is the recommendation.

Illustrative examplePhoenix, AZ

Industrial load and demand

A plant where short interruptions cost production and a few hours a month set peak demand.

Evaluates: Process load and shift pattern, what sets the peak, ratchet exposure, and site constraints.
Structures: On-site generation, storage for peak management, resilience-only, or doing neither.
Decision logic: Cost and continuity are separated — the right answer for one is rarely right for the other.
Why it fits: If dispatch constraints hurt operations, solve resilience first and revisit generation later.

Illustrative exampleHouston, TX

Community / utility-scale

A site with a real development case, an uncertain queue position, and capital on a fixed timeline.

Evaluates: Site control, interconnection and study status, permitting exposure, schedule and counterparties.
Structures: Develop to notice-to-proceed, sell earlier in a structured exit, or joint venture.
Decision logic: Timing governs: a queue position clearing after the capital window is worth less than an earlier exit.
Why it fits: Execution risk is priced explicitly, and not proceeding stays on the table.

Residential backup, alternative structure

A household with a high delivered rate, winter outages, and little appetite for upfront capital.

Evaluates: Outage history, which circuits must stay live, heating load, roof condition, and transfer on sale.
Structures: Standalone storage, solar plus storage, a third-party owned structure, or no system.
Decision logic: Resilience and savings are separate purchases; a storage-first step is often more defensible.
Why it fits: Under a third-party structure incentives sit with the owner, so we compare delivered cost and terms.

Residential rooftop + storage

Example scenario: a household with a summer bill several times its winter bill, a recent time-of-use rate change, and two outages the previous year.

What Iterum evaluates: Iterum would start with twelve months of billed usage and the current rate schedule, then look at roof age and orientation, evening load, and how much of the bill is actually shiftable into a battery.
Structures considered: Ownership with cash, financed ownership, and a third-party owned PPA — each with and without storage.
Decision logic: In a project like this the comparison usually turns on tax appetite and how long the household intends to stay. If the roof needs work inside a few years, the honest answer may be to re-roof first and revisit.
Why it could fit: Storage is sized to the loads that matter during an outage rather than to the whole panel, and any incentives that apply are confirmed during analysis.
