Project Overview Massachusetts Electric Company (“MECO”), New England Power Company (“NEP”) (both MECO and NEP, d/b/a National Grid) and PPM Energy, Inc.1 (“PPM”) (together, the “Petitioners”) propose to construct a new overhead 34.5 kilovolt (“kV”) tie line (the “proposed project” or “proposed tie line”) to connect the planned Hoosac Wind Project, a 30 MW project using 20 commercial scale wind turbines, with the New England Power Company transmission system (Exh. MECO/PPM-1, at 3). The proposed tie line would begin at PPM’s planned Hoosac Wind project on Tilda Hill Road in Florida (at the point where cables from the planned Hoosac Wind project intersect with Tilda Hill Road) and continue along the existing rights of way (“ROWs”) in Florida for approximately 0.44 miles (Exh. MECO/PPM-2, at 2). At the Florida/Monroe town line, Tilda Hill Road becomes Main Road and the line would follow Main Road, Kingsley Hill Road and River Road in Monroe for approximately 5.6 miles to a new substation to be located off River Road in Monroe Bridge Village in Monroe (id. at 3). At the new substation the proposed line would interconnect to the adjacent New England Independent System Operator (“ISO-NE”) transmission grid through tap lines from the new substation to the existing NEP 69 kV transmission line adjacent to the new substation (id.). The total length of the 1 PPM Energy, Inc. (“PPM”) is a developer of wind energy projects in the United States that acquired the interests of enXco, the initial developer of the Hoosac Wind Project, in February 2006 (MECO/PPM-2, at 5). PPM itself was acquired in April 2007 by Iberdrola, a Spanish utility (id. at 2). PPM plans to construct the Transmission Line, substation and tap line at its expense, and, when construction is complete, turn over ownership of the Transmission Line to MECO and the ownership of the substation and tap line to NEP (id.). D.P.U. 07-80 Page 2 tie line would be approximately 6.1 miles (Exh. MECO/PPM-3, at 4). Neither the Hoosac Wind Project nor the new substation are the subject of the petition (Exh. MECO/PPM-2, at 3). B. Procedural History On September 28, 2007 the Petitioners filed a petition with the Department of Public Utilities (“Department”) pursuant to G.L. c. 164, § 72, seeking authority from the Department to construct, maintain and operate the proposed tie line. The Petitioners seek a determination by the Department that the proposed electric transmission line is necessary and will serve the public convenience and be consistent with the public interest (id.). The petition was docketed by the Department as DPU 07-80. On November 28, 2007, after notice duly issued, the Department conducted a public hearing in Florida, Massachusetts. The Department received no petitions to intervene. The Department held an evidentiary hearing on March 7, 2008 at the Department’s Boston offices. In support of its petition, the Petitioners sponsored the testimony of seven witnesses: Thoms R. Shields, II; Robert A. Sproesser; Jason A. Krzanowski; Randall P. Christensen; Daniel L. Mahoney; Peter A. Valberg; and David C. Klinch. The Department moved 19 exhibits (including 15 information requests and pre-filed testimony of four Company witnesses) into the record. On April 2, 2008 the Petitioners filed a brief. The Petitioners explained that because the design, construction, operation and maintenance of the proposed interconnection facilities require the cooperation and joint effort of MECO, NEP and PPM, all three parties filed a joint petition with the Department. However, the Petitioners further explained that only MECO and NEP are each an “electric company” subject to D.P.U. 07-80 Page 3 G.L. c. 164, § 72 (Petitioners’ Brief at 3). The Petitioners stated that, therefore, any order issued by the Department should only apply to MECO with respect to the 34.5 kV tie line and to NEP with respect to the 69 kV tap lines, as MECO and NEP will ultimately own, operate and maintain the 34.5 kV tie line and 69 kV tap lines (id.). The Petitioners stated that PPM would be acting as an agent of MECO and NEP for the design and construction of only the 34.5 kV tie line and the transmission line-related substation equipment (id.). II. STANDARD OF REVIEW General Laws c. 164, § 72, requires, in relevant part, that an electric company seeking approval to construct a transmission line must file with the Department a petition for: authority to construct and use … a line for the transmission of electricity for distribution in some definite area or for supplying electricity to itself or to another electric company or to a municipal lighting plant for distribution and sale … and shall represent that such line will or does serve the public convenience and is consistent with the public interest .... The [D]epartment, after notice and a public hearing in one or more of the towns affected, may determine that said line is necessary for the purpose alleged, and will serve the public convenience and is consistent with the public interest.2 The Department, in making a determination under G.L. c. 164, § 72, is to consider all aspects of the public interest. Boston Edison Company v. Town of Sudbury, 356 Mass. 406, 419 (1969). Section 72, for example, permits the Department to prescribe reasonable conditions for the protection of the public safety. Id. at 419-420. All factors affecting any phase of the public interest and public convenience must be weighed fairly by the Department in a determination 2 Pursuant to G.L. c. 164, § 72, the electric company must file with its petition a general description of the transmission line, a map or plan showing its general location, an estimate showing in reasonable detail the cost of the line, and such additional maps and information as the Department requires. D.P.U. 07-80 Page 4 under G.L. c. 164, § 72. Town of Sudbury v. Department of Public Utilities, 343 Mass. 428, 430 (1962). In evaluating petitions filed under G.L. c. 164, § 72, the Department examines: (1) the need for, or public benefits of, the present or proposed use; (2) the environmental impacts or any other impacts of the present or proposed use; and (3) the present or proposed use and any alternatives identified. New England Power Company d/b/a/ National Grid, D.T.E. 06-37, at 2-3 (2007); Boston Edison Company d/b/a NSTAR Electric, D.T.E. 04-71, at 2-4 (2005); Commonwealth Electric Company d/b/a NSTAR Electric, D.T.E. 05-1, at 2-3 (2005); Massachusetts Electric Company, D.T.E. 03-130, at 2-3 (2004). The Department then balances the interests of the general public against the local interests and determines whether the line is necessary for the purpose alleged and will serve the public convenience and is consistent with the public interest.3 III. DESCRIPTION A. Project Overview The Petitioners propose to construct, operate and maintain a 6.1 mile overhead 34.5 kV tie line connecting the Hoosac Wind Project located off Tilda Hill Road in Florida, MA to the ISO- 3 In addition, the Massachusetts Environmental Policy Act (“MEPA”) provides that “[a]ny determination made by an agency of the commonwealth shall include a finding describing the environmental impact, if any, of the project and a finding that all feasible measures have been taken to avoid or minimize said impact” (“Section 61 findings”). G.L. c. 30, § 61. Pursuant to 301 CMR 11.12(5), these findings are required if the Secretary of Environmental Affairs has required an Environmental Impact Report (“EIR”) for the project. The Company informed the Department that no EIR is required for the proposed project (Tr. 1, at 122-123). Accordingly, Section 61 findings are not necessary in this case.

In general, the region is separated from the Pioneer Valley and the rest of the state by the Berkshire Highlands and the Hoosac Range that serve as its eastern boundary and by the Taconic Mountains that serve as its western boundary with upper New York State. Lanesborough is located in north-central Berkshire County and is bordered to north by New Ashford, to the east by Cheshire and Dalton, to the south by Pittsfield and to the west by Hancock. The town is 18,764 acres in size, which is approximately 30 square miles. Lanesborough is situated at the headwaters of the two major river watersheds in the county: the Housatonic River, which flows southward through Connecticut to Long Island Sound, and the Hoosic River, which flows northward into the Hudson River, which ultimately flows into the Atlantic Ocean.

As a result, the $10.5 million synchronous-condenser system for power factor correction (losses of up to 3%) will not be completed until about the end of 2013. There are many factors reducing ridge line IWT CFs. Here is an excerpt from http://theenergycollective.com/willem-post/169521/wind-turbine-energy-capacity-less-estimated Below are some numbers regarding the much less than expected results of the Maine ridge line IWTs for the past 12 months. http://www.coalitionforenergysolutions.org/maine_wind_thru_3q2012m1.pdf Mars Hill, 42 MW 0.353; uniquely favorable winds due to topography.

    Busby Trail to Spruce Hill Savoy Mountain State Forest SELF-GUIDED HIKING TOUR WELCOME to Savoy Mountain State Forest, 10,200 acres managed by the Massachusetts Department of Conservation and Recreation, and located in the towns of Savoy, Florida, Adams and North Adams. Savoy Mountain has many miles of wooded trails offering opportunities for year-round passive recrea- tion. Much of this state forest was acquired by Massachusetts beginning in1918, assembled from aban- doned farmland. Many farming residents, tired of poor conditions, had moved into valley towns of Ad- ams and North Adams to work in the woolen mills, or headed west for better farmland. The evidence of these farms remains with old orchards and stone fences and a cellar hole found along the Busby Trail. Please remember to carrycarry----in,in, carrycarry----outout all your belongings, including trash. Please leave no trace of you visit, and leave all that you find in its natural environment for all to enjoy. Thank you.

  • Mohawk Trail West Ch3 Natural Resources
    CHAPTER 3 Natural Resources long the Mohawk Trail Scenic Byway lies a wealth of important natural resources. Among these resources are: the Deerfield and Hoosic Rivers, which contain important trout habitat; the Glacial Potholes in AShelburne Falls, one of the largest collection of such potholes in the country; the Natural Bridge in North Adams, the only bridge in North America created by the erosive forces of water; and miles of northern hardwood forests along the Byway corridor, including old growth forests in the Mohawk Trail State Forest. The Byway also includes other geologic, flora and fauna, water resources that help make the Mohawk Trail Scenic Byway experience unique. The corridor’s natural resources contribute to the dramatic scenery viewed from the Byway, and attract recreational tourists seeking to experience the corridor’s wildness. This chapter of the Corridor Management Plan provides a gen- eral inventory and overview of the Byway’s natural resources, in- cluding its geology, soils, water resources, and rare species habitat areas. The purpose is to highlight the Byway’s primary natural and environmental assets. The chapter also discusses potential issues that could affect the quality of these resources over time, especially if the Byway experiences an increase in tourist and vehicle traffic. The chapter closes with a series of recommendations for protect- ing, maintaining, and enhancing the Byway’s natural resources. ago, a period of mountain building Geologic Resources (also known as an orogeny) called the Taconic Orogeny created the Taconic Geologic History Hills of western Berkshire County.

Gentlemen : — Enclosed please find the annual report of the Greylock Reservation Commission. Very respectfully yours^ FRANCIS W. ROCKWELL, Chairman. GREYLOCK RESERVATION COMMISSION. PiTTSFiELD, Mass., Jan. 1, 1916. To the Committee on Revision. Gentlemen : — The records kept by the secretaries of the Greylock Reservation Commission are very brief. In order to keep the public informed, and to make it easier for the gentlemen who may succeed the present com- mission, we place in the annual report facts and references which will give a better understanding of the work of the Commission. These references will enable all interested hereafter in the reservation to find what has been done and the methods employed in the general conduct of reservation matters. While the records in the State Auditor's, State Treasurer's and Attorney-General's offices will explain the expenditure of the funds appropriated by the Commonwealth, and while the annual reports of the treasurer of the Commis- sion to the Berkshire county commissioners will aid in the matter, it remains true that many matters of interest can be found only in the county press, — hence the references to the newspapers of Berkshire. Many inquiries pertaining to the history of the mountain and reservation are made of the Commission. These ques- tions can best be answered by the references given in the brief bibliography and references written for this report.
