- Summary:
- In this paper we present methods for separating wind's impact into regulation and load following (imbalance) time scales. We show that approximating these impacts with simpler methods can significantly distort cost causation and even cause confusion between the relevant time scales. Correctly calculating and allocating cost impacts provide a market signal that can encourage economic efficiency and avoid subsidies. We present results from NREL's wind data collection program to illustrate some of the dangers of linearly scaling wind resource data from small wind plants to approximate the wind resource data from large wind plants. Errors in scaling can cause a significant over-estimate of wind impacts in the regulation and load following time frames and result in cross-subsidies in the resulting tariff. Finally, we provide a framework for developing regulation and imbalance tariffs, we outline methods to begin examining contingency reserve requirements for wind plants, we provide guidance on the important characteristics to consider, and we provide hypothetical cases that the tariff can be tested against to determine whether the results are desired.
