Several parties discussed the types of products or transactions that should not be authorized for interim procurement. In their testimony, the CEC, TURN and ORA recommend limiting or prohibiting certain types of transactions.
CEC gave several recommendations for restrictions on utility transactions, including: prohibiting utilities from entering into bilateral contracts with affiliates, limiting procurement arrangements to one year or less, prohibiting any utility from entering into contracts that limit the operations of any of its utility retained generation (URG) units (with the exception of "interchange" transactions, where one utility sends energy to another over a specified time frame in exchange for energy at another time).
ORA recommends that the utilities be prohibited from entering into asymmetric derivative contracts. ORA does not provide an argument as to why such types of arrangements should be disallowed. Edison, in its rebuttal testimony, found the ORA position to be inconsistent, citing ORA's support for hedging devices such as call and put options.
The use of financial instruments (derivatives) in such a manner that their effect would be to amplify the net portfolio price risk shall not be allowed. By its definition, a hedge is used based upon an entity's underlying portfolio position to mitigate price risk; actions taken by a utility that amplify net portfolio risk are prohibited.
The procurement products listed in Table 1 represent a compilation of the types of procurement products requested by the respondent utilities in testimony, as well as products that we consider appropriate to meet procurement needs. While we authorize the utilities to procure the products described in Table 1, this list should not be considered exhaustive. The procurement plans must specify each utility's comprehensive list of products, including a definition of each product type and the associated benefit/cost attributes.
Table 1 Authorized Procurement Products | ||
Transaction |
Description |
Benefit /Cost |
Forward Spot (Day-Ahead & Hour-ahead (purchase, sale, or exchange) |
Purchase pre-scheduled energy or load reductions at fixed price |
Needed to balance short-term load/resource changes/ Vulnerable to price volatility |
Real-time (purchase or sale) |
Energy imbalance transactions or load reductions |
Balances Short-term needs/ Vulnerable to price volatility |
Forward Energy (purchase or sale) |
Contracts entered into in advance of delivery time, includes block/forward products (e.g., fixed amounts of energy over a specified period of time (e.g., 7x24, 6x16, super-peak, and shaped products) Could be fixed price |
Reduces price risk / Risk that prices will be below contracted rate |
Forward Energy (demand side) |
Baseload usage reduction through investments in permanent energy efficiency |
Reduces price risk and cost overall |
Capacity (purchase or sale) |
Right to purchase energy in exchange for capacity payment. If exercised, buyer also pays incremental energy charge at specified rate |
Reduces spot price risk / Reduced risk comes at cost of reservation and energy charges |
Capacity (demand side) |
Right to purchase load reductions for capacity payments |
Provides dispatchable reliability |
On-site energy or capacity |
Energy or capacity products self-generated on the customer side of the meter |
Provides locational reliability and lowers price risk through supply diversity |
Tolling Agreement |
Type of capacity product where buyer hedges fuel cost risk by providing the gas supply, transportation, and storage |
Reduces peak price risk / Buyer pays reservation or capacity charges, and is open to gas price risk |
Peak for off-peak exchange |
Trades peak energy for off -peak energy (x peak MWh < y off-peak MWh) |
Reduces peak price risks / Increases off-peak price risks |
Seasonal exchange |
Buyer receives peak energy in Summer and returns peak energy in Winter |
Reduces summer price risk /Increases winter peak price risk |
Physical call (or put) option |
Deal to purchase energy in future at pre-set price (price may be pegged to an index). [Call is right to purchase, put is right to sell.] |
Call reduces price risk, with option to not exercise right if prices lower. Put insulates from reduced value of excess energy / Fee associated with these rights |
Financial call (or put) option |
Caps energy price without losing the benefit of lower prices. Price of energy is capped at a fixed price; at times when an agreed upon index price falls below the fixed (strike) price, the buyer pays the lower index price |
Reduces price risk / Reduced risk comes at price of option premium (fee) |
Financial swap |
Buyer gets or pays difference between floating price index and a fixed negotiated price |
Locks in fixed price (reduces price risk) / Cost if negative difference between floating index and fixed price |
Insurance (Counterparty credit insurance, cross commodity hedges) |
Buyer can insure against various adverse events (such as extreme temperature, a generating unit failure, or counterparty default, among others), to reduce price risk |
Insurance policies can reduce price risk, but increase energy costs by the amount of the insurance premium |
Electricity Transmission Products |
Arranged through CA ISO and with non-CAISO transmission owners. Also includes purchase of transmission rights or use of locational spreads. |
Reduces price risk associated with varying transmission conditions. |
Gas Transportation Transaction |
Buyer contracts for transportation of gas to a determined delivery point, at a set price (could be fixed or variable) over a specified time-frame |
Reduces price risk associated with gas transportation (and therefore, limits some electric generation price risk for gas-fired units) |
Gas Storage |
Buyer reserves gas storage capacity for a defined price |
Hedges price risk associated with gas storage |
Gas Purchases |
Purchased on a monthly, multi-month, or annual block basis |
Used to hedge fuel cost risk associated with capacity contracts |
Ancillary Services |
Replacement reserve, regulation up, regulation down, spinning-reserve, non-spinning reserve |
Needed to assure system reliability |
