Managing Cumulative Imbalances

Noncore customers have three options for managing cumulative imbalances:

Manage their own imbalances:
- A noncore customer is responsible for trading imbalances, as
  well as paying any applicable imbalance charges*
Authorize nominating marketer to trade imbalances:
- A nominating marketer is responsible for trading imbalances,
  but the noncore customer remains responsible for any applicable
  imbalance charges*
- A nominating marketer is designated on the customer's Natural
  Gas Service Agreement, Exhibit C
Assign imbalances to a balancing agent:
- A balancing agent may be a marketer managing many customer imbalances
  or may be a noncore customer managing imbalances for multiple
  premises
- A balancing agent is responsible for trading imbalances as well
  as paying any applicable imbalance charges*
- A balancing agent must meet Pacific Gas and Electric Company's creditworthiness
  requirements (see Gas Rule 25)
- A noncore Balancing Aggregation Agreement (NBAA) must be executed
  between Pacific Gas and Electric Company, the balancing agent and the customer

* Imbalance charges may include balancing, Operational Flow Order (OFO), Emergency Flow Order (EFO) and Involuntary Diversion charges.
