Energy cost recovery for industrial facilities
Plants, mills, processors and other industrial sites are billed under the most complex utility tariffs there are. That complexity is where overcharges hide, and where an audit recovers them.
Energy cost recovery for industrial facilities is the process of finding utility billing errors on a plant's electricity and natural gas accounts, claiming refunds for past overcharges within the period each state allows, and correcting the accounts so the savings continue. Discovery Energy Utility Audits does this on contingency for manufacturers and other industrial companies, usually for 15% to 50% of refunds and verified savings, with no upfront fee. Its documented industrial results include $374,326 for a national steel company and $3,959,202 for a multi-state renewable natural gas producer.

Why industrial bills carry more errors
An office is billed on a simple commercial rate. A plant is billed on a large-power or industrial rate with demand charges, ratchets, power factor adjustments, time-of-use periods, voltage-level discounts, standby or backup service, interruptible credits and riders that depend on how the customer is classified. Gas accounts add transport service, balancing, pressure and heat-content factors. Every one of those settings is a place an account can be set up wrong, and plants change: new lines, shutdowns, meter exchanges, on-site generation and ownership changes all happen without the utility re-checking the account.

Utility billing errors in industrial manufacturing
| Error | How it happens at a plant | What it costs |
|---|---|---|
| Wrong rate class | Load grew or changed shape; the account stayed on the rate it opened on | A higher rate on every kWh and kW, every month |
| Classification and riders | Manufacturing use not documented, so the account carries riders or surcharges an industrial customer would not | Extra charge lines that repeat |
| Demand and ratchets | A start-up peak sets a ratchet for 11 months; an old ratchet percentage still applied | Paying for demand the plant no longer uses |
| Meter multipliers | Wrong constant after a meter or transformer change | Every reading, demand and capacity tag inflated |
| Seasonal rates | Summer rates applied early or late | Higher rates for whole billing periods |
| Capacity tags | Peak load contribution calculated from bad data | A year of capacity cost at the wrong quantity |
| Gas service and factors | Wrong gas rate or transport class, heat-content or pressure factor | Over-billed therms or the wrong rate on every unit |

How recovery works
Authorize
A letter of authorization lets Discovery request 36 to 48 months of bills, interval data and account records from each utility.
Test every account
Every charge is recalculated under the tariff in force for each period, against how the plant actually uses power and gas.
Claim
Findings go to the utility with the tariff provisions and the math. First findings usually arrive in 30 to 60 days.
Refund and correct
Formal refunds usually take a further 60 to 120 days; the account is moved to the right rate or setting going forward.
Keep it right
In an ongoing engagement, new bills are reviewed at least monthly in TaraBase so a new error is caught in the month it starts.
How far back a refund can reach is set by state rules and utility tariffs, typically 1 to 5 years; see utility refunds by state. Errors found late cost more than the refund: every month outside the look-back is lost.

Questions buyers ask
What is energy cost recovery for industrial facilities?
Finding utility billing errors on a plant's electricity and gas accounts, claiming refunds for past overcharges and correcting the accounts going forward. Discovery Energy does it on contingency.
What are the most common utility billing errors in industrial manufacturing?
Wrong rate class, missing or wrong riders tied to classification, demand ratchet and power factor errors, meter multiplier errors after equipment changes, seasonal rate timing, capacity tag errors and, on gas accounts, wrong service class or conversion factors.
Does an audit disrupt plant operations?
No. It is an off-site records review. There are no site visits, no equipment and no capital spending.
How do business utility brokers secure refunds for overcharged accounts?
Most brokers focus on supply contracts and do not audit delivery charges. Refunds for utility overcharges come from a tariff audit that documents the error and claims it with the utility, which is what Discovery does.
