How do we work?

Our methodology

How we lower utility costs: the savings disciplines, the finding pipeline, and how every recommendation is sourced and reviewed before it reaches a client.

Last reviewed 2026-05-27

Audit working surface

At Developments CS, methodology is the disclosed analytical method that sits behind every recovered dollar. Each commercial utility bill in scope flows through a finding pipeline that runs 27 distinct detection rules across 10finding categories. Every candidate finding is then reviewed by a human analyst, cross-checked against the controlling primary source (the utility's filed tariff, a Public Service Commission order, a signed supply contract, or a published program rule), and presented to the client with the underlying calculation and the citation before any filing is made. We publish the taxonomy below so prospects, clients, and reviewers can see exactly what we look for. We publish the source of every numeric claim on this site so each one is defensible. We publish our editorial standards so the way we name, update, and correct work is on the record.

What we look for

The 27 finding types, grouped into 10 categories

Every account we audit is run against the catalog below. Recovery ranges reflect typical commercial-portfolio outcomes across the practice, drawn from engagements spanning every ISO and RTO footprint in the country. The specific dollar value of any single finding depends on the account class, the controlling tariff, and the duration of the issue. The same finding categories appear in every state.

CATEGORY

Tariff

3 finding types

Plain-English definition and typical recovery range

Rate misclassification
Account is on a rate schedule it does not qualify for, or fails to qualify for a more favorable schedule it could move to.
Typical recovery$5,000 to $80,000 per year, per account
Rate change impact
Utility rate case or PSC order changes the applicable rate; account was not migrated to the optimal schedule under the new regime.
Typical recovery$2,000 to $40,000 per year, per account
Green rider optimization
Account enrolled in a green-power rider when a comparable supply offering at lower cost is available, or not enrolled when a hedged renewable option would reduce volatility.
Typical recovery$1,500 to $25,000 per year, per account
CATEGORY

Metering

3 finding types

Plain-English definition and typical recovery range

Estimated reading
Bill is based on an estimated meter read rather than an actual read for consecutive cycles, producing distortion that requires reconciliation.
Typical recovery$500 to $12,000 per occurrence
Meter multiplier suspect
Applied CT or PT multiplier in the billing system does not match the physical equipment installed at the meter base.
Typical recovery$3,000 to $200,000 in retroactive refunds
Sewer oversized meter
Sewer charge is billed against a water meter sized for a load larger than actual use, common in retrofits and downsized operations.
Typical recovery$2,000 to $30,000 per year, per account
CATEGORY

Demand

4 finding types

Plain-English definition and typical recovery range

Demand spike
Single-interval peak demand event drives the billed demand for the month substantially above the operational baseline.
Typical recovery$1,500 to $18,000 per event
Demand ratchet
Utility's ratchet clause locks the billed demand to a percentage of the highest peak in the prior eleven or twelve months, sustaining cost long after the original spike.
Typical recovery$6,000 to $60,000 per year, per account
Power factor penalty
Account is assessed a low-power-factor penalty under the tariff, recoverable through correction equipment or supply-side adjustment.
Typical recovery$3,000 to $35,000 per year, per account
Load factor poor
Account's load factor is low enough that a different rate structure (real-time pricing, time-of-use, primary service) would reduce annualized cost.
Typical recovery$4,000 to $45,000 per year, per account
CATEGORY

Tax

2 finding types

Plain-English definition and typical recovery range

Tax exemption gap
Account is eligible for sales-tax, gross-receipts, or franchise-fee exemption under state law but the certificate is not on file with the utility.
Typical recovery$8,000 to $250,000 plus prior-year refunds
Franchise fee error
Municipal franchise fee is billed at the wrong rate, applied to the wrong jurisdiction boundary, or applied to a non-franchised account class.
Typical recovery$2,000 to $40,000 per year, per account
CATEGORY

Billing

4 finding types

Plain-English definition and typical recovery range

Billing period anomaly
Bill spans an unusual number of days, overlaps a tariff change, or fails to reconcile against the prior cycle's meter close.
Typical recovery$300 to $9,000 per occurrence
Late fee questionable
Late fee assessed where the payment was timely under the tariff's grace window, or where the prior balance was disputed and unresolved.
Typical recovery$100 to $5,000 per occurrence
Duplicate charge
Same line item appears twice on a bill, or the same charge appears across two bills in a single billing window.
Typical recovery$200 to $12,000 per occurrence
Payment error
Payment was misapplied, applied to the wrong account, or returned despite valid funds, resulting in cascading late fees and reconnection threats.
Typical recovery$500 to $15,000 per occurrence
CATEGORY

Usage

3 finding types

Plain-English definition and typical recovery range

Consumption spike
Consumption rises substantially above the trailing-twelve-month baseline without a corresponding operational change, indicating a meter, leak, or load anomaly.
Typical recovery$1,500 to $40,000 per occurrence
Consumption flat
Consumption is suspiciously constant across periods with known operational variation, indicating possible meter freeze, estimation, or stuck register.
Typical recovery$1,000 to $20,000 per occurrence
Historical anomaly
Multi-year pattern shows deviation from comparable accounts in the same class, utility, and territory, surfacing a structural rather than transactional issue.
Typical recovery$2,000 to $50,000 per year, per account
CATEGORY

Charges

3 finding types

Plain-English definition and typical recovery range

Supply delivery imbalance
Supply and delivery charges are inconsistent with the contracted supply rate and the published delivery tariff for the rate class.
Typical recovery$2,500 to $60,000 per year, per account
Minimum charge excess
Account is being assessed a minimum-bill or minimum-demand charge that exceeds the rate the account would qualify for on a different schedule.
Typical recovery$1,500 to $25,000 per year, per account
Budget billing error
Budget-billing reconciliation accumulates a credit or debit that diverges from actual usage, producing a true-up or stranded credit at year end.
Typical recovery$500 to $18,000 per year, per account
CATEGORY

Regulatory

1 finding type

Plain-English definition and typical recovery range

Regulatory overcharge
A PSC order or rate-case settlement has not been correctly applied to the account, producing an overcharge against the approved tariff.
Typical recovery$1,000 to $35,000 per year, per account
CATEGORY

Incentives

2 finding types

Plain-English definition and typical recovery range

Grant available
A federal, state, or utility incentive program for which the account is eligible has not been claimed, with funding window still open.
Typical recovery$5,000 to $500,000 one-time, plus performance payments
Demand response eligible
Account qualifies for a demand-response program (PJM Capacity Performance, Synchronized Reserve, utility-administered DR) but is not enrolled.
Typical recovery$3,000 to $120,000 per year, per account
CATEGORY

Contract

2 finding types

Plain-English definition and typical recovery range

Contract expiry
Supply contract is approaching expiry without a renewal strategy, exposing the account to provider-of-last-resort default service at unfavorable rates.
Typical recovery$4,000 to $200,000 per year of unhedged exposure
Aggregation opportunity
Multiple accounts under common ownership could be aggregated under a single supply contract or rate schedule for material price improvement.
Typical recovery$10,000 to $300,000 per year across the portfolio

Where our numbers come from

Every published statistic, with its sample basis

Numeric claims that appear elsewhere on this site are sourced below. If a number on the site does not have a corresponding entry here, that is a defect: tell us and we will either source it or remove it.

  • Basis. Computed from invoices reviewed across 200+ commercial accounts audited between 2018 and 2026 across every ISO and RTO footprint in the country (PJM, ERCOT, CAISO, ISO-NE, NYISO, MISO, SPP). An invoice is counted as containing an error when at least one chargeable line item, tax application, or rate adjustment is determined incorrect against the active tariff revision in effect during the billing period. The rate is broadly consistent across regulated and deregulated states alike; we note when a particular jurisdiction's sample basis differs materially.

  • Basis. 27 distinct finding types catalogued across 10 finding categories. Each type is documented in the finding taxonomy section above and corresponds to a specific detection rule in the audit pipeline. Catalog evolves quarterly as new tariff provisions, PSC orders, and billing-system error patterns are observed in the portfolio.

  • Basis. Cumulative count of distinct commercial property owners, municipalities, or public entities for which Developments CS has performed at least one full engagement between 2018 and 2026. A single portfolio may contain multiple accounts, locations, and utility relationships across one or more states.

  • Basis. Range of annualized recovery as a percentage of in-scope spend across tariff-audit engagements where at least one tariff finding was implemented. The lower bound reflects accounts already on a near-optimal schedule with a single secondary opportunity; the upper bound reflects accounts where rate-class migration was indicated and accepted.

  • Basis. Range of annualized demand-cost reduction across demand-management engagements that resulted in operational, programmatic, or rate-side intervention. Includes ratchet-driven recoveries, demand-response enrollment, power-factor correction, and rate-class migration affecting demand billing.

  • Basis. Median elapsed time from authorization to first utility-processed recovery (refund posted, exemption certificate accepted, tariff switch effective, program enrollment confirmed). Distribution skews toward the shorter end for billing-forensics and tax-recovery findings, and toward the longer end for tariff migrations and program enrollments with statutory waiting periods.

How a finding becomes a recovery

Five steps from detection to settlement

No automated detection becomes a client-facing recommendation without passing through every step below. The process is the reason the finding-type catalog above does not produce false positives in client-presented work.

  1. STEP 01

    Automated detection

    Every bill in scope flows through the finding pipeline, which runs 27 detection rules against the parsed line items, the active tariff revision, and the account's trailing-twelve-month profile.

  2. STEP 02

    Human analyst review

    A candidate finding produced by automated detection is reviewed by an analyst against the source bill, the tariff document, and the account history before it advances to the next stage.

  3. STEP 03

    Primary-source cross-check

    Each reviewed finding is cross-checked against the controlling primary source: the utility's filed tariff book, the relevant PSC or PUC order, the account's signed supply contract, or the program administrator's published terms.

  4. STEP 04

    Client review meeting

    Confirmed findings are presented to the client with the underlying calculation, the source citation, the recommended action, and the expected recovery range, before any filing or contract change is initiated.

  5. STEP 05

    Filing, recovery, and verification

    On client approval, the recovery action is filed with the utility, tax authority, program administrator, or counterparty, and the resulting credit, refund, or rate change is tracked through utility settlement and reconciled against the original calculation.

What we read

Primary sources we cite in every engagement

Every finding ties back to a controlling primary source. The list below is not exhaustive; for each state where we hold accounts, the working reading list is the active tariff book for every utility serving the account, the live rate-case docket at the state PSC or PUC, the relevant ISO or RTO market documentation (PJM, ERCOT, CAISO, ISO-NE, NYISO, MISO, SPP), the program rules for incentives the account qualifies for, and the federal regulators where applicable. The methodology of citing the controlling tariff, PSC order, contract, or program rule does not change from one state to the next.

Utility tariff books (examples)

The filed and approved rate schedules, riders, and general terms for each utility serving an account in scope. Every tariff finding cites the schedule and revision number. The list below is illustrative; we read the active tariff book for every utility serving every account, in every state.

State Public Service Commissions, Public Utility Commissions, and equivalents

The orders, settlements, and active rate-case dockets that change the tariffs above. Tracked continuously; cited by docket number in every regulatory finding. We read from the commission serving every state where an account sits; the list below is the illustrative reading list for the states most represented in the portfolio.

ISO and RTO market documentation

The wholesale capacity, energy, transmission, and ancillary market rules and settlement data for the seven ISOs and RTOs that cover the country. Demand response enrollment, transmission cost recovery (including ERCOT 4CP), and capacity tag corrections all read from these.

Federal regulators and data

FERC filings and Energy Information Administration (EIA) datasets that govern wholesale, capacity, and transmission costs reflected in commercial bills nationwide.

Incentive and program administrators (examples)

State, utility, and federal program documents that govern eligibility, application windows, and payment structures for incentives we file on client behalf. The list below is illustrative; we read the live rules for every program an account qualifies for in every state.

Independence

We work for the client, never the utility

Developments CS earns no referral fees from competitive suppliers, community solar projects, demand-response aggregators, or efficiency program administrators. We hold no equity in projects we enroll clients in. The engagement structure (retainer or contingency) is documented in the engagement letter, and no compensation accrues from any party other than the client. This is the constraint that lets us recommend the action that is best for the account, not the action that is best for someone paying us on the side.

Editorial standards

How we update, correct, and frame the work

The conventions below govern what appears on this site, how it changes, and how engagements are referenced in any public-facing material.

Update cadence
Statistics on this site are reviewed quarterly and republished with a new dateModified. Finding taxonomy and recovery ranges are reviewed annually or whenever a tariff change, PSC order, or new finding type materially affects the catalog.
Corrections policy
When a published figure or claim is found to be incorrect, the page is updated, a brief correction note is added at the bottom of the page, and the dateModified is bumped. We do not silently edit numbers that prospects and clients may have relied on.
Engagement naming
Engagements are never identified by client name or street address in any public-facing content. Where examples appear in case studies, on this site, or in published materials, the engagement is described by anonymized class (multifamily portfolio, regional healthcare campus, school district), the utility involved, the tariff code or finding type, and the dollar range. Specific entities are never named without prior written client approval.
Case study definition
A case study on this site is either a real engagement that the client has signed off on for publication (named explicitly when so), or an engagement archetype assembled from common patterns observed across multiple anonymized engagements (labeled explicitly when so). The two are never combined in a single study, and the framing is always disclosed on the case study itself.
Independence disclosure
We earn no referral fees from competitive suppliers, community solar projects, demand-response aggregators, or efficiency program administrators. We hold no equity in projects we enroll clients in. Engagement structure (retainer or contingency) is documented in the engagement letter; no compensation accrues from any party other than the client.
