RI Offshore Wind Stakeholders Final Report

In the summer of 2007, Rhode Island Governor Carcieri invited representatives from Rhode Island communities, the state’s environmental community, maritime businesses and industry, and governmental officials to participate in discussions regarding the development of a wind farm in Rhode Island area waters. A study commissioned by Rhode Island in 2006 and completed in winter of 2007 had determined that 15% or more of Rhode Island’s electricity requirement could be supplied by offshore wind farms and, further, that 10 specific areas were suitable for consideration as wind farm locations. The Stakeholder Process was a series of four meetings in August, September, and October 2007. Meeting attendees included stakeholders (defined as town and city representatives, environmental organizations, local economic development organizations, and commercial fishing interests) as well as other participants (including state government agencies, U.S. Coast Guard, area university representatives, National Grid, consultants to the RI Office of Energy Resources, and others) who contributed technical information to the process.

Stakeholders identified a set of issues that they felt could, would, or should affect the siting of offshore wind farms in Rhode Island area waters. The Office of Energy Resources’ consultants then provided stakeholders with additional information to help focus and clarify the issues raised and determine, where possible, which issues were most relevant to which sites.

The Stakeholder process was successful in identifying issues that appeared to be particular to some sites and not others. There was agreement that the formal environmental impact analysis and permitting processes that will come next, if Rhode Island elects to further pursue the wind option, can be used to compare and contrast the relative merits of the alternative sites.

Overall, participants in the Stakeholder process expressed their support for the concept of using wind energy to satisfy some portion of Rhode Island’s future electricity needs, their approval that the Governor and Office of Energy Resources are investigating this potential opportunity for Rhode Islanders, and their desire to continue participating in future discussions and decision making on this topic.

RI Renewable Energy Fund

The Rhode Island Renewable Energy Fund (“Fund”) is dedicated to increasing the role of renewable energy in Rhode Island’s electricity supply. Renewable energy technologies harness the energy in sunlight, the wind, biomass (growing plant matter and organic wastes) flowing water, waves, tides, or the heat of the earth, to make electricity in a cleaner and more sustainable manner than sources we have traditionally relied on in the past. More recently, the Comprehensive Energy Conservation, Efficiency and Affordability Act of 2006 (R.I. Gen. Laws 39-2-1.2) included a provision that the Renewable Energy Fund be self-sustaining, and as a result, OER has re-directed its efforts to supporting initiatives that can provide a return investment to the Fund. Low-interest loans and re-payable grants are some of the mechanisms in place to help spur renewable energy development in the state.

Some major Fund activities include:


Portsmouth Abbey Wind Turbine

In 2004, Rhode Island’s first utility-scale wind turbine was built at the Portsmouth Abbey School in Portsmouth, Rhode Island and is located on 500 acres overlooking Narragansett Bay. The 660 kilowatt wind turbine was the largest single investment made by the Fund, and is producing 1.25 million kilowatts of electricity per year. The turbine is serving 40 percent of the annual electricity demand of the school, one of the area’s largest consumers of energy. Most importantly, this project has helped to dispel misconceptions about large scale wind. Now operational for one year, the turbine has become a beacon of renewable energy for the state. Neighbors who had expressed reservations about its size and noise are now pleased with the final result.

Other Wind Activity…

Meteorological towers have been placed at a number of different locations around the state, providing valuable information about Rhode Island’s wind resources. In addition, these towers have provided background for a number of feasibility studies, also financed through the Renewable Energy Fund.

RI Wind Alliance

All interested parties are invited to join one of the working groups established by the Rhode Island Wind Alliance (RIWA). These working groups are an important part of the grass-roots effort to promote wind power in our State.

You may just sign-up to receive a monthly or bimonthly update, or you may sign up to help with one or more of the following: A. Coordination among towns, B. Selecting sites to install wind-turbines, C. Estimating costs, D. Calculating income, E. Figuring out how to finance, F. Working on community outreach, G. Informing through the media, H. Helping shape legislation or any number of specific task forces listed under each one of the Action Groups. You do not have to be a Rhode Island resident to register or sign up to help with a Task Force.

RI Wind Mapper

The Wind Mapper features average wind speed data from AWS Truewind, as well as areas constrained by bedrock, slope, hydric soils or seasonal high water tables (RIGIS data). The Wind Mapper is intended as a general resource for those interested in exploring the possibility of wind power in their community and is NOT a substitute for site-level evaluation.

RI Wind Conference

In April, 2007 the Office of Energy Resources, in cooperation with the University of Rhode Island, Roger Williams University, and the Washington County Regional Planning Office hosted a very successful wind conference at the University of Rhode Island called “From Local to Global: the Rhode Island Model for Harnessing Wind Power Worldwide.

Oceanlinx Wave Project

Since 2003, the RI Renewable Energy Fund has been working with an Australian company, Oceanlinx (formerly Energetech) on demonstrating an ocean wave energy project off the coast of Pt. Judith, and more recently, Block Island. Ocean wave energy is a large world wide energy resource. The World Energy Council has estimated that the technical potential of ocean wave energy is more than 2 Terrawatts (1 TW = million megawatts) or about two-thirds the current world wide energy demand. Ocean wave devices, when commercialized, will contribute to national and local energy security and increase supply diversity. Direct environmental benefit is through the displacement of fossil fuel based energy. Much of the labor and materials for construction and installation will be spent in the proximity of the deployed ocean wave devices.

Project Overview

The Oceanlinx project will be a moored system at Point Judith Harbor of Refuge, seaward of the East Arm of the Breakwater. The Project will have a maximum power capacity of 750 kilowatts and a preliminary analysis indicates an annual average of 225 kilowatts.

The system employs the concept of the Oscillating Water Column (OWC) which consists of a partially submerged, hollow structure, which is open at the bottom to allow water to flow in and out. Due to the effect of the ocean waves, the rising and falling motion in the chamber caused the trapped air to flow to and from the atmosphere via a turbine.

The Oceanlinx OWC includes two innovative devices: a parabolic wall to capture more energy in the OWC, and a bi-directional variable pitch turbine, resulting in greater efficiency.

Visit the Oceanlinx Web site at www.oceanlinx.com for more information.

Tidal In-Stream Energy Conversion

The Office of Energy Resources funded a feasibility study for tidal power in the town of Warren, RI. The project would capture the energy in an estuary with a current of approximately five knots. Based on the information in the study, the project area appears to be suitable for development of a TISEC array that could create the model for community-based energy and distributed generation. The project area has the requisite minimum power density, bathymetry, minimal user conflicts, and proximity to both load and interconnection.

Hydropower Support

In May, 2006 the Office of Energy Resources approved a low-interest loan for the Harris Mill project, a mill conversion project to apartments and condominiums, and will include the installation of an energy-efficient turbine and cogeneration plant that will produce more than 10 million kilowatt hours of electricity. Located in Coventry, RI, the $1.5 million project is financed equally from a $500,000 low-interest loan from the Office of Energy Resources’ Renewable Energy Fund, private equity, and a bank loan. The Fund will also receive an additional two cents per kWh from the sale of REC’s created by the project. The Pawtuxet River Authority will also receive two cents per kWh paid from the REC’s.

Several other hydropower feasibility studies have been funded including the Holliston Sand project in North Smithfield, RI (1 MW), and the Hope Mill project in Scituate, RI (1 MW).

Rhode Island Solar on Schools Initiative

The Solar on Schools Initiative provides each of the participating school systems with a solar photovoltaic (PV) installation, as well as web-based data display on the PV system performance. The data collection and display system allows teachers and students to access system performance data and use it in science or other curricula. Through the web-based system, participating schools and other education-oriented institutions can compare the operating results of their PV systems to that of other schools in the Program. Each of the participating schools receives:

A 2000-watt solar photovoltaic installation, including data acquisition and performance tracking system, and
A Heliotronics Data Monitoring System and energy curricula, including teacher training, mentoring, course materials and internet access to the PV system output data of the schools and institutions participating in the Program.

The major portion of the funding for the cost of the PV system and the educational support will come from the Renewable Energy Fund and the Office of Energy Resources. Participating schools must provide a nominal amount toward the cost of the program. Each school must identify a team of teachers from who have a strong interest in making the educational aspects of the Program a success. An additional requirement is that the PV panels themselves be sited in a location with a high degree of visibility for the community.

The following Rhode Island Schools have received PV systems under the Solar on Schools program:

  • Veterans Memorial High School, Warwick
  • Ponaganset High School, North Scituate
  • Park View Middle School, Cranston
  • Wickford Middle School, North Kingstown

Basic Solar Information

Solar cells (also called photovoltaics) absorb sunlight and convert it directly to electricity. Solar cells are very thin (about 1/100th of an inch thick). Most are rectangular or circular wafers made of silicon (sand), but some consist of a thin film that is mounted on glass or thin metal.

When sunlight hits the cell, electrons are released. The electrons then flow onto wires, forming direct current (DC), which is the same kind of current that flows from a battery. A number of cells (usually 20 or more) or a film can be mounted within a frame under a transparent glass or plastic covering to form a module. Modules can be connected to other modules to form an array. Solar modules can be free-standing units, but there are also building-integrated solar products, such as solar roof shingles.

The Two Types of Photovoltaic Systems

There are two types of photovoltaic systems: (1) stand-alone systems and (2) systems that are connected to the electric power lines of the utility grid. Stand-alone, or independent, systems are especially well matched to settings far from electric power lines. They also work well with portable road signs and other devices that are used in locations where it would be costly or inconvenient to connect them to the utility grid.

Homeowners with stand-alone systems are completely independent of the utility gird, relying on their own power systems to meet all their electricity needs. They connect their solar cells to batteries that store electricity for use when the sun is not shining. In some physically isolated settings, it can cost a homeowner $10,000 or more to connect to the utility grid, so a solar electricity system can be quite cost effective.

Most people in the Northeast who purchase a solar system will want to choose a utility-connected one. In these cases, the electricity from the system supplements what is available to the building from the electric utility. When the solar cells do not provide sufficient electricity for the building's users, extra electricity is supplied by the utility and the building¹s electric meter runs forward to record that extra electricity used. But at times when the solar cells produce more than enough electricity for the building¹s users, the additional power is fed back into the utility grid and the building¹s electric meter runs backwards, recording the "sale" of the electricity to the utility. This arrangement, in which the electric meter runs both forward and backward, is called net metering. In the Northeast, net metering is supported by legislation in all New England states, Maryland, New York, and Pennsylvania.

Fixed versus Tracking Systems

Photovoltaic systems, whether grid-connected or grid-independent, can also be configured to be either fixed or tracking systems. Fixed systems are mounted at a set angle in such a way that the angle cannot be adjusted. The fixed angle is selected based on geographic location. In the Northeast, the optimal angle for a fixed system is typically the location's latitude or latitude minus 15 degrees.

Tracking systems come in either single-axis or two-axis designs. Single-axis trackers move throughout the day, following the path of the sun across the horizon. Two-axis tracking systems not only follow the path of the sun throughout the day, but they also adjust their horizontal angle throughout the year in response to the position of the sun in the sky as it changes from season to season. Although tracking systems generally produce more energy, they are more expensive and require more maintenance than fixed angle systems.

Most are rectangular or circular wafers made of silicon (sand), but some consist of a thin film that is mounted on glass or thin metal. They are the building block of modules and arrays.
  • Photovoltaic Effect. The process by which sunlight generates electricity in a photovoltaic cell. The cell has several layers. The back of the cell is commonly made of crystalline silicon, doped with a chemical that creates positively charged spaces or "holes" in the crystalline structure. The front of the cell is doped with a chemical that creates an abundance of negatively charged electrons. When sunlight passes through the front layer, the added energy knocks "loose" some of the electrons, which jump to the positively charged "holes". The movement of electrons is the flow of electricity and this can be channeled away through thin wires embedded in the cell to a load to do work.
  • Photovoltaic System. A complete set of components for converting sunlight to electricity, storing that electricity, and delivering it to its end use.

Ponaganset High School Fuel Cell Project

Education through demonstration and projects-based learning are key components of Ponaganset High School’s Fuel Cell Education Initiative. The demonstration projects began with the creation of Protium, the world’s first fuel cell-powered band, and led to the creation of a Rhode Island’s first fuel cell vehicle, a two passenger Quadracycle. After completing successful test drives with the fuel cell Quadracycle it was decided to embark on another project, one significantly more ambitious. After considerable brainstorming, Ponaganset High School’s Model T project was born. For this project a full size, street legal replica of a 1923 Ford Model T Roadster was selected for powerplant conversion from a gasoline-chugging Chevrolet 350 cubic inch V8 engine to a zero pollution electric vehicle. The Model T project was planned to develop in two phases, with phase I being the conversion to battery electric power and phase II being the integration of a fuel cell power system. The RI Renewable Energy Fund was able to assist this project, and continues to track its amazing progress.

Renewable Energy Incentives for Homeowners

Rnewable energy products, as defined in section 44-56-1 of the general laws in chapter 44-56, are exempt from sales tax in the state of Rhode Island.

The State of Rhode Island has a residential renewable energy system tax credit which offers a 25% income tax credit for homeonwers who install renewable energy systems including solar domestic hot water systems, solar space heating systems, wind energy systems, geothermal, and photovoltaic energy systems. (General Law Chapter 44-57, section 44-57-2, 44-57-4, 44-57-5 AND 44-57-7).

Beginning January 1, 2006, a federal tax credit is available that provides a 30% tax credit, up to a maximum of $2,000 per system/for each solar technology. eligible technologies include PV, solar domestic heating (excluding pool heating). The credit applies to the basis remaining after any state or utility incentives available to the taxpayer have been takne. Be sure to consult your tax professional for tax advice.

Homeowners who wish to apply for the renewable tax credit must provide certain information, depending on the type of technology installed, to the Office of Energy Resources.

Distributed Generation

The Comprehensive Energy Conservation, Efficiency and Affordability Act of 2006 directed the Office of Energy Resources to facilitate a stakeholder-led study of issues and barriers related to the implementation of distributed generation in the state. A diverse group was convened including state government officials, consumer groups, environmental and renewable energy advocates, municipal government representatives, distributed generation equipment marketers and manufacturers, residential customers, large institutional and industrial customers, and National Grid electric and gas representatives. As required, the Final Report was delivered to the RI General Assembly on February 1, 2007.

RIWINDS, or RI Energy Independence 1.

In January 2006, the State of Rhode Island established the RIWINDS program to promote the development of wind energy in the state. Shortly after this time, Governor Carcieri set an ambitious goal of obtaining 20% of the state's renewable energy resources by 2011. A little over one year later, a final report was released at the RI Wind Energy Conference at the University of Rhode Island which identified the most viable areas for wind energy development in the state.
