Curtailment

HOW DO CUSTOMERS RESPOND TO REAL-TIME PRICING?

Even when the customer is a commercial or industrial organization, the answer can prove illusive.

Real-life responses to RTP depend on the entirety of the incentive and monitoring systems, group dynamics and individual personalities. Managers within an organization respond to RTP signals based on information and incentives that only they can know and comprehend. Only people employed by the organization are privy to these intangibles, which remain highly idiosyncratic within any organization.

All three may apply, especially if regulators go wrong and let ISOs make the business decisions.

Electricity transmission is a real business. With more than $50 billion of net plant, another $3 billion annually in capital expenditures and yearly operating income that could reach $5 billion per year under normal circumstances, the power grid is roughly twice the size of the natural gas pipeline industry. One would never know that from current events, however. Utility management treats transmission as an inconvenient stepchild.

Sound bites from state and federal regulators.

Refusal to Wheel. Federal judge allows rural electric co-op to proceed with antitrust suit against PacifiCorp, ruling that doctrine of state action immunity does not insulate a regulated investor-owned electric utility from antitrust action for allegedly refusing to sell to sell power to others for resale to customers, or for allegedly refusing to wheel power generated by other suppliers.

The New York Public Service Commission has set up procedures to reimburse qualifying cogeneration and small power production facilities if any of the state's seven investor-owned electric utilities should curtail purchases of power from the QFs. The Independent Power Producers of New York Inc. blasted the decision.

The PSC said it will review QF requests for reimbursement if a utility is alleged to have curtailed purchases unfairly.

Gas Curtailment. New York PSC approves updated curtailment and interruption tariffs for many of the state's natural gas local distribution companies. It had asked the LDCs to develop new rules to reflect growing competition and ensure gas deliveries for core customers during a supply crunch. Case 93-G-0932, March 24, 1997 (N.Y.P.S.C.).

T & D Classification. New York PSC opens proceeding to distinguish between electric transmission and distribution facilities.

Leslie K. Norford, and Richard D. TaborsAs facility manager for a large hotel, you browse your energy vendor's web site to view tomorrow's hourly prices. But it seems your computer (pc) has already done some browsing of its own. Since it's connected to your energy management system, your pc has already looked up the weather forecast and has logged on to the hotel's main computer to find out what rooms will be used.
