PROJECT DETAILS
Beaver Ridge Wind is a 4.5 megawatt, 3-turbine wind project. This was the second operational wind farm in Maine. RLC provided engineering, communications, and commissioning oversight services for the 34.5 kV collector system, project interconnection and turbine to SCADA communications.
SCOPE OF SERVICES
PROJECT DETAILS
The Canton Wind Project is an 8-turbine facility located on Canton Mountain in Canton, Maine. The project now connects to the existing Central Maine Power 115 kV system via 3.4 miles of overhead and 1.8 miles of underground 34.5 kV collector system that interconnects at the Ludden Lane substation, which was expanded for this project.
SCOPE OF SERVICES
PROJECT DETAILS
RLC provided engineering services that developed the preliminary engineering documents necessary for the submittals of the Utility Interconnection Application and the Annual Energy Production Report. This work is for a solar system that will utilize more than 100 acres of land for development. The initial project was to provide conceptual documentation of a proposed minimum 7.5 MWac photovoltaic based generation facility, which has expanded in physical area and output to a potential 20 MWac site.
SCOPE OF SERVICES
PROJECT DETAILS
RLC served as Owner’s Engineer for the client in the Commonwealth of Massachusetts. The client was committed to develop up to 70 MWdc of solar systems, 35 MWdc in each of the Eastern and Western districts. The plan, which called for the construction of new facilities across the commonwealth, increased the amount of solar power produced by the client in Massachusetts from eight megawatts previously up to 70 megawatts statewide. Along with the significant environmental benefits of increasing the number of utility-scale solar plants in Massachusetts, there will be substantial cost-saving benefits for the client’s customers as well.
SCOPE OF SERVICES
The Solar Program consisted of the following:
PROJECT DETAILS
The Transmission Lightning Arrester Application Study project was to provide an investigation into the transmission line outages caused by lightning events on certain transmission lines. The Utility requested a review of the lightning related outages to determine if the frequency of these outages was outside the norm and if design modifications could improve the performance of those lines. RLC was responsible for investigating the causes and made recommendations on potential mitigation options based on our field inspections. The intent of this investigation was to determine the most feasible mitigation alternative to reduce the number of outages caused by lightning.
SCOPE OF SERVICES
PROJECT DETAILS
The Canadian Solar Project consists of multiple, utility scale, photovoltaic facilities. RLC performed the role as Owner’s Engineer to review and comment on their design, construction efforts and practices. The installed facilities range from 8-10 MW each. The projects are unique in that they utilize a mix of solar panels from 14,000 up to 56,500 panels per site. The overall effort included the development of the following six project locations.
PROJECT DETAILS
RLC performed design and engineering services for New England Battery Storage for their Madison Jones Street project. The Madison ESS is New England’s first fully integrated front-of-the-meter energy storage facility. It is a 4.99 MW / 10 MWh lithium-ion system that participates in the ISO-NE wholesale energy markets, operating reserve markets, frequency regulation market, and capacity market.
SCOPE OF SERVICES
PROJECT DETAILS
The Passadumkeag Wind Project is a 13 turbine 39.975 MW wind project interconnected to the Emera Maine 115 kV transmission system. The wind turbines are Vestas V112-3.075 MW wind turbines equipped with the grid streamer control system.
SCOPE OF SERVICES
PROJECT DETAILS
The Saddleback Ridge Wind Project is a 34.2 MW wind project employing 12 – 2.85 MW GEWE wind turbines. The project utilized approximately 13.5 miles of underground and overhead electrical collector system to interconnect with CMP’s high voltage system. Interconnection to the CMP system required the establishment of a new, 115 kV 3-breaker ring-bus switching substation. Environmental constraints established the need for an intensive transmission corridor study. The substation transforms the collector circuit voltage from 34.5 kV to 115 kV allowing interconnection to CMP’s Section 229. The substation is also configured to provide for interconnection with the Canton Mountain Wind Farm project.
SCOPE OF SERVICES
PROJECT DETAILS
Eversource contracted RLC to review the inspection reports and photos of the transmission structures. An examination of the available information was used to develop a spreadsheet with an analysis of the structures. Each structure was graded using the EPRI Field Guides category A through D. Along with the grading system, notes of the structure deficiencies were provided. The inspection project provided Eversource with a way to assess the condition of 26,000 existing structures.
SCOPE OF SERVICES
PROJECT DETAILS
The Canton Wind project consists of 8 – 2.85 MW GEWE wind turbines. This project includes, but is not limited to, the Balance of Plant electrical engineering design work. This design work is necessary for the establishment of a new 115/34.5 kV line terminal at Ludden Lane substation, as well as a 34.5 kV aerial line between the new 34.5 kV line terminal, the ridgeline riser structures, and the 34.5 kV underground system from the ridgeline risers to the wind turbine switchgear. The design work is also essential to the associated communication/SCADA systems.
SCOPE OF SERVICES
PROJECT DETAILS
RLC performed design and engineering services for New England Battery Storage for their Madison BTM project. This is a 1.5 MW / 3.10 MWh battery energy storage system that will provide load reduction that provides services to the ISO-NE wholesale energy markets. This project began commercial operation in December of 2019. This project helps the Madison Electric Works reduce energy costs to their consumers.
SCOPE OF SERVICES
PROJECT DETAILS
The Pisgah Mountain Wind Project consists of 5 – 1.8 MW Vestas wind turbines located on Pisgah Mountain. This project includes, but is not limited to, the Balance of Plant electrical engineering design work necessary for the 34.5 kV underground system from the turbines to the riser poles; the 34.5 kV overhead line between turbines and to the new substation; the 34.5 kV to 115 kV substation; the interconnection to BHE Section 66 and the communication/SCADA system.
SCOPE OF SERVICES
PROJECT DETAILS
Spruce Mountain Wind consists of 10 – 2.0 MW Gamesa G87 Wind Turbines. The project interconnects to a new 34.5 kV three-phase roadside distribution circuit from Woodstock Substation. RLC was hired to facilitate the interconnection process and to serve as the project electrical engineers to design the collector system and communications for construction and for the permit application.
