Day-Ahead Hourly Pricing (DAHP) is a rate class that is available to full-service customers of Con Edison. Under Day-Ahead Hourly Pricing, customers pay hourly retail electric energy rates that reflect the hourly changes in wholesale energy rates. There are often significant differences in hourly wholesale pricing in response to supply and demand. This method can be of great benefit to the customer who can shift load to non-peak hours, when electric rates are typically lower.

How It Works
Customers can take advantage of Day-Ahead Hourly Pricing by installing an Energy Management System or by using various load-curtailment strategies, which can include such measures as dimming lobby lighting or shutting down some of the elevator banks in a large office building. The New York Independent System Operator (NYISO) issues hourly wholesale prices - called day-ahead prices - for the next 24-hour day. Based on these prices, Con Edison will in turn relay hourly wholesale prices via the Internet to its Day-Ahead Hourly Pricing customers.

Customer Eligibility
Any full-service Con Edison customer with an interval meter can participate in DAHP. Customers with peak electric demand more than 1500kW are automatically enrolled in DAHP. Curtailable Electric Service, Power For Jobs, Power Your Way, Economic Development Delivery Service, and NYISO economic curtailment customers are excluded.

Incentives
Customers who shift load or employ other strategies in response to day-ahead hourly pricing information can garner substantial savings over time. Con Edison will help customers assess the effect of changing from current rates to Day-Ahead Hourly Pricing. Con Edison representatives will walk customers through their potential savings and make suggestions for workable savings strategies. As an added bonus, customers will receive Internet-based software, which can be used to identify ways to reduce electricity consumption and lower operating costs.

Requirements
Customers choosing this option must agree to stay on the rate for a minimum of one year. Customers must have an interval meter (s) with a telephone line (s). The meter measures and records electrical use each hour; the data are used to verify load reduction and calculate appropriate payment. Incentives are available for the cost of the interval meter installations through New York State Energy Research and Development Authority (NYSERDA).
