Testing the effectiveness of an experimental acoustic bat deterrent at the Maple Ridge wind farm

2008mapleridgeacousticbatdeterrent_thumb This paper documents the results of an in-field test at the Maple Ridge wind energy facility in New York to determine the effectiveness of using an experimental acoustic bat deterrent to reduce bat mortality. The executive summary excerpted below suggests the results were inconclusive. Most bat experts remain unconvinced that acoustic deterrence will be a suitable mitigation approach to reduce bat fatalities at existing turbines.

Grid Impacts of Wind Power Variability: Recent Assessments from a Variety of Utilities in the United States

Ewec06gridpaper_thumb In this report we discuss some recent studies that have occurred in the United States since our previous work [2, 3]. The key objectives of these studies were to quantify the physical impacts and costs of wind generation on grid operations and the associated costs. Examples of these costs are (a) committing unneeded generation, (b) allocating more load-following capability to account for wind variability, and (c) allocating more regulation capacity. These are referred to as “ancillary service” costs, and are based on the physical system and operating characteristics and procedures. This topic is covered in more detail by Zavadil et al. [4].

The Effects of Integrating Wind Power on Transmission System Planning, Reliability, and Operations:Report on Phase 2: System Performance Evaluation

The_effects_of_intergrating_wind_power_on_transmission...._thumb "In response to emerging market conditions, and in recognition of the unique operating characteristics of wind generation, the New York Independent System Operator (NYISO) and New York State Energy Research and Development Authority (NYSERDA) commissioned a joint study to produce empirical information that will assist the NYISO in evaluating the reliability implications of increased wind generation. The work was divided into two phases. Phase 1, Preliminary Overall Reliability Assessment, was completed in early 2004. This initial phase provided a preliminary, overall, screening assessment of the impact of large-scale wind generation on the reliability of the New York State Bulk Power System (NYSBPS). This document was prepared by General Electric International, Inc. in Schenectady, NY. It is submitted to THE NEW YORK STATE ENERGY RESEARCH AND DEVELOPMENT AUTHORITY (NYSERDA). Editor's Note: In the Executive Summary, GE argues that 'imbalance' penalties should not be imposed on wind: "subimbalance penalties should not be imposed on wind generation. Wind projects would need to settle discrepancies between their forecast and actual outputs in the energy balancing market. However, because wind is largely nondispatchable, any additional penalties for imbalance should be eliminated. [emphasis added] The FERC Order 888 allows imbalance penalties to be applied to generators that operate outside of their schedule. As applied in New York, any “overgeneration” can be accepted without payment and any “undergeneration” is priced at the greater of 150% of the spot price or $100/MWh. Strict application of these policies in the MAPS analysis performed would result in the loss of roughly 90% of the wind generation revenue, which would be disastrous to their future development."(page 2.8)
