Frequently Asked Questions: Imbalance Trading

Can imbalance trades occur between noncore and core customers?

Yes, imbalances may be traded between noncore customers, balancing agents and core procurement groups.

Can I trade past zero? That is, can I go from 5% overdelivered to 3% underdelivered?

You can trade Cumulative Imbalances past zero, as long as any individual trade moves your imbalance closer to zero and does not move past zero by more than 3%.

Is the 3% of usage automatically calculated when I try to trade past zero?

That validation automatically occurs for Cumulative Imbalance trades. Operating Imbalances can not be traded past zero.

How will I know my usage number for the month?

The usage number will appear on your imbalance statement.

Is how much I can trade into and out of storage tied to the 5% Tolerance Band?

No. You can trade all of your Cumulative Imbalance with storage within the limits of your storage inventory or capacity. The 5% Tolerance Band is used as the basis for determining volumes subject to cashout.

I have a large balance in my storage account. Should I be concerned about reducing or eliminating it?

No, storage balances are not subject to balancing provisions. You may, however, use your storage account as a balance trading tool. PG&E provides you with your storage balance, along with the account names, to make it easier for you to do so.

Does storage have a Tolerance Band?

Storage has nothing to do with imbalances and carries no charges associated with balancing. Storage is a trading tool that may be used to resolve imbalances.

Are there limits to my use of core storage for balancing? Does it affect my rights to withdraw or inject gas later?

Your use of storage for balancing is limited only by the OP Band and by your storage inventory or capacity. Your withdrawal and injection rights are not used in imbalance trading. You will, however, be subject to withdrawal or injection charges.

Is the Web tool the only way to submit imbalance trades, or can I send faxes?

Although it will still be possible to submit trades by fax, you would be at a disadvantage in doing so. PG&E would enter your trade using the same imbalance trading tool available to you, but the timing of that trade would be out of your control.

If I'm a Core Transport Agent, does that mean that I won't have an imbalance for three months?

No, a Core Transport Agent would have a Cumulative Imbalance from the supply month prior to trading and an Operating Imbalance from three months prior to trading.

Is my MDQ affected by imbalance trading?

No, imbalance trading is not considered a transmission service, so your MDQ remains unaffected.
