New Solar + Storage Microgrid Project to Provide Resilient Power

Unique Federal-State-Utility-NGO Partnership Supports New Approach to Protect Communities

Montpelier, VT: Clean Energy Group/Clean Energy States Alliance applauds the announcement of a groundbreaking solar + storage microgrid project in Rutland, Vermont. The Stafford Hills project is being developed by Green Mountain Power, in collaboration with Dynapower and GroSolar. The energy storage component of this project is co-funded by a unique federal-state-NGO partnership involving the State of Vermont; the U.S. Department of Energy, Office of Electricity; and the Energy Storage Technology Advancement Partnership (ESTAP), a project managed by Clean Energy States Alliance and Sandia National Laboratories.


"This project is a national model for the future of clean energy – combining solar with energy storage," said Lewis Milford, president of Clean Energy Group, which manages the Clean Energy States Alliance. "Solar power and battery storage will provide clean reliable power to a school that serves as an emergency shelter, helping a community cope with loss of power in a future disaster. This new form of resilient power is what all communities need to protect themselves from power outages in severe weather events."

Dr. Imre Gyuk, Energy Storage Program Manager in the Office of Electricity Delivery and Energy Reliability, U.S. Department of Energy, commented, "This project provides resilient power during emergencies while benefitting the grid at other times. The technical innovations will reduce cost and make the project commercially viable…. This is the perfect project! It has social value, technical innovation, and furthers renewable integration for the grid."

This project is unique in several ways:

*It is one of the first exclusively solar-powered microgrids in the US, and the first to provide full back-up to an emergency shelter on the distribution network;

*It is the first solar+storage microgrid to be developed on a brownfield site, contributing to brownfield redevelopment efforts in Rutland, VT;

*It incorporates 7,722 solar panels, capable of generating 2.5 MW of electricity, helping GMP to reach its goal of making Rutland, VT the Solar Capital of New England, and helping Vermont to reach its renewable energy goals;

*It incorporates 4 MW of battery storage, both lithium ion and lead acid, to integrate the solar generation into the local grid, and to provide resilient power in case of a grid outage;

*It incorporates innovative multi-port inverters designed specifically for this project by Dynapower, a local Vermont firm;

*It will provide resilient power to a Rutland school that serves as a public emergency shelter (additional critical facilities may be similarly supported by this microgrid in the future);

*It will provide clean, distributed generation and resilient power to an economically challenged, urban community that is targeted for revitalization, and that suffers frequent power outages due to storms;

*It was partially funded through a joint federal/state partnership for deployment of energy storage technologies;

*It is part of Green Mountain Power's larger vision for transforming Rutland into "The Energy City of the Future."

This project puts Vermont in the forefront of the new movement toward microgrids, energy storage, and grid modernization. Solar + storage and microgrid technologies are poised to revolutionize resilient power, bringing clean, locally-generated power to communities all over the world. These systems can keep critical facilities, such as emergency shelters, firehouses and fueling stations, operating when the grid goes down. There is a great need for such resilient power solutions, as shown by recent disasters such as Hurricane Sandy, which affected the entire eastern seaboard and left millions without electrical service. With this project, Vermont takes a giant step toward addressing this need, as well as meeting Vermont's clean energy and emissions reduction goals.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
