In a recent rate case order, the Illinois Commerce Commission denied Nicor Gas Company's request to continue a pilot program allowing customers to purchase carbon offsets from the utility to offset 100% of the customer's natural gas usage

Nicor's TotalGreen program (Rider 40) offers customers two choices to green their gas supply -- an option with 99%+ carbon offsets and less than 1% from renewable natural gas credits, and a premium option that includes 80-95% carbon offsets and 5-20% renewable natural gas credits

TotalGreen is a pilot with a previously set expiration date of June 30, 2027.

Nicor had sought to make TotalGreen permanent, and to add a new price option under which the offsets would be a fixed fee per month, rather than the cost varying with usage

In joint submissions, the Environmental Law & Policy Center, and the Environmental Defense Fund & the Illinois State Public Interest Research Group, Inc. (ELPC/PIO), had said during the rate case that, at one point, Nicor had spent $2,429 per customer in administrative costs under TotalGreen, with most of such costs deferred

ELPC/PIO said that TotalGreen enrollment three years into the pilot stood at 238 customers, or 0.01% of Nicor's total customers

ELPC/PIO also said that about one-third of TotalGreen participants from the initial year of the program ceased TotalGreen service.

ELPC/PIO argued that the TotalGreen pilot generated limited environmental benefits

The Illinois Competitive Energy Association (ICEA) and the Retail Energy Supply Association (RESA) also opposed continuation of TotalGreen, alleging that Nicor's stated low administrative costs of the program are a "mirage" due to deferrals

The ICC in its rate case order agreed that, "it is clear there is little customer interest in the [TotalGreen] program."

The ICC thus declined to allow continuation of TotalGreen beyond its current expiration date

The ICC added that, "The Commission notes deferred costs for a program represented without a revenue requirement impact are not recoverable through rates."

The ICC said that it is "eager" to consider programs that will benefit ratepayers while generating environmental benefits. However, the Commission said that such an undertaking is more appropriately addressed as part of the separate Future of Gas (FoG) proceedings

"The Commission encourages all to continue to innovate programming that benefits ratepayers and creates environmental benefits, and to utilize the FoG workshops as an avenue to further explore and develop such programs," the ICC said

The rate case also addressed several other retail market issues, with the ICC granting relief sought by retail suppliers in some instances, but declining suppliers' sought relief on other matters

The ICC declined to adopt most of ICEA/RESA’s proposed reforms to Nicor’s storage-related operations, and rejected suppliers' proposals for (1) same-day trading, (2) daily imbalance trading (retroactive trading), and (3) monthly imbalance trading.

However, the ICC did agree that retail suppliers should not be subject to penalties from Nicor for instances in which tariff noncompliance is "directly attributable" to the lack of timely and necessary data from Nicor

ICEA/RESA had alleged that Nicor has been imposing cash-out penalties in instances in which Nicor allegedly failed to timely provide data needed for a supplier to reallocate nominations between their own pools. ICEA/RESA alleged that such practice by Nicor is contrary to tariff

Specifically, the ICC adopted ICEA/RESA’s proposal that Nicor shall forgo penalties or issue refunds in instances where data is not made available prior to the close of the reallocation window.

With regards to other storage issues raised by suppliers, the ICC expressed concern that retroactive nominations could, "compromise operational reliability and increase gas supply costs."

However, while not adopting the reforms at this time, the ICC did require Nicor to further study ICEA/RESA’s proposal to allow retroactive daily and monthly imbalance trading, and to analyze any impact on Nicor's storage operations. Nicor shall report on the estimated costs to implement any changes

During the case, Nicor and ICEA/RESA agreed that the Gas Supplier Operations Portal (GSOP) would be revised to include information indicating whether a meter reading is an actual meter reading, or an understated meter read.

Beyond this agreement between the parties, the ICC declined to adopt additional transportation-related proposals from ICEA/RESA, citing implementation costs

Notably, ICEA/RESA had sought a streamlined process for a supplier to access historical customer usage

Currently, to access historical usage, if the supplier does not provide a letter of agency, the supplier must provide the exact dollar amount of the customer’s last bill.

ICEA/RESA had suggested a more automated process, or alternatively, the adoption of the process in place at Ameren, which only requires the account number and an online verification that a supplier is permitted by the customer to access the information.

The ICC said that the historical usage issue is better addressed in Nicor's retail supplier forum (Supplier Connection)

The ICC approved an increase in the Group Charge in Rider 13 (Supplier Transportation Service) to $205, more than double the current charge of $95

Among other things, ICEA/RESA had proposed basing a supplier's individual Group Charge on the supplier's number of customers (the suppliers proposed that a per-customer fee would be determined, and then applied to each supplier based on its number of customers)

The ICC rejected such a Group Charge mechanism at this time, but said that it is willing to re-examine the issue in the future

The ICC approved Nicor's increase in the Group Change Fee to $35 from the current $25

ICEA/RESA had in the case proposed that Nicor rely on EDI to automate adds and drops from transportation pools, similar to the mass market, and that the fee should not be increased

The ICC rejected ICEA/RESA's automation proposal, citing concerns about a $750,000 implementation cost as stated by Nicor

The ICC also declined at this time to increase the pool cap from 600 accounts to an unlimited number

The ICC observed that the pool cap was only recently increased to 600, and said that, "Despite the raised cap, the interest in utilizing it was minimal as only two of fifteen suppliers utilize a group size over 500 customer accounts."
