Maine PUC considers NTA coordinator

Friday, April 8, 2016

Maine utility regulators have launched an investigation into the designation of a "Non-Transmission Alternative Coordinator."  The case could shape whether and how Maine coordinates alternatives to electric transmission line development.

Non-transmission alternatives or NTAs are smart grid programs and technologies that complement and improve operation of existing electricity transmission systems, deferring or eliminating the need for upgrades to the transmission system.  NTAs can an deliver improvements to the grid at a lower cost than some transmission projects.  Distributed generation, storage, and demand response can play roles in NTA projects.

In Maine, legislative policy supports selecting NTAs over transmission development if an NTA can meet an identified reliability need at a lower cost to consumers than the proposed transmission project.  But under current law, no single entity formally coordinates or is required to postulate alternatives to transmission development.

In previous cases, the Maine Public Utilities Commission has investigated the need for a smart grid coordinator, approved a non-transmission alternative pilot project in the Boothbay region, and considered the scope of what an NTA Coordinator might do.  From these dockets, a vision has emerged of the NTA Coordinator as an entity that would develop cost-effective alternatives to transmission projects.  Under this vision, the NTA Coordinator would address the policy and goals of the Maine's Smart Grid Policy Act to “improve the overall reliability and efficiency of the electric system, reduce ratepayers’ costs in a way that improves the overall efficiency of electric energy resources, reduce and better manage energy consumption and reduce greenhouse gas emissions.”

But key questions remain, including whether and how an NTA Coordinator will be designated, the scope of its functions and duties.  Another fundamental question is whether these functions will be performed by transmission and distribution utilities, or by some third party entity.

In a Notice of Investigation dated April 4, 2016, the Maine Public Utilities Commission opened its investigation into these questions.  The notice describes the proceeding as focused on one approach to economically optimizing the electric system between generation and transmission:
Specifically, through this proceeding, the Commission expects to address this legislative policy by (1) developing the framework for selecting a NTA Coordinator and (2) determining the scope of the NTA Coordinator’s functions and duties. The Commission will also resolve the question of whether a third party entity or the transmission and distribution (T&D) utilities should perform the NTA Coordinator functions. This investigation will also address the role of an Advisory Planning Committee (APC) and the process for NTA development both within a CPCN proceeding and for transmission and distribution projects that are not required to file a CPCN petition. Finally, an end-product of this proceeding will be either the contours of an RFP or that of a rate incentive proposal should the Commission determine that the utility and not a third party should perform the functions of an NTA Coordinator.
Along with the notice of investigation, the Commission also issued "Strawman" and "Process Chart" documents for comment.

The notice set deadlines for filing petitions to intervene by April 21, 2016, and for comments on the Strawman and Process Chart by April 28, 2016.  An initial case conference was scheduled for May 12, 2016.

Maine offshore wind projects win federal grants

Wednesday, December 12, 2012

The U.S. Department of Energy has announced an award of funding to seven offshore wind Advanced Technology Demonstration projects totaling $168 million over six years.  These projects are designed to achieve large cost reductions over existing offshore wind technologies and develop viable and reliable options for the United States.  Waters off Maine will be home to two of the projects:

  • Statoil North America of Stamford, Connecticut plans to deploy four 3-megawatt wind turbines on floating spar buoy structures in the Gulf of Maine off Boothbay Harbor at a water depth of approximately 460 feet. These spar buoys will be assembled in harbor to reduce installation costs and then towed to the installation site to access the Gulf of Maine's extensive deep water offshore wind resources.

  • The University of Maine, based in Orono, plans to install a pilot floating offshore wind farm off Monhegan Island.  This project will feature two 6-megawatt direct-drive turbines on concrete semi-submersible foundations. These concrete foundations could result in improvements in commercial-scale production and provide offshore wind projects with a cost-effective alternative to traditional steel foundations.
Each project will receive up to $4 million to complete the engineering, site evaluation, and planning phase of their project.  Five other projects were also selected for this first phase:

  • Baryonyx Corporation, based in Austin, Texas, plans to install three 6-megawatt direct-drive wind turbines in state waters near Port Isabel, Texas. The project will demonstrate an advanced jacket foundation design and integrate lessons learned from the oil and gas sector on hurricane-resistant facility design, installation procedures, and personnel safety.

  • Fishermen's Atlantic City Windfarm plans to install up to six direct-drive turbines in state waters three miles off the coast of Atlantic City, New Jersey. The project will result in an advanced bottom-mounted foundation design and innovative installation procedures to mitigate potential environmental impacts. The company expects this project to achieve commercial operation by 2015.

  • Lake Erie Development Corporation, a regional public-private partnership based in Cleveland, Ohio, plans to install nine 3-megawatt direct-drive wind turbines on "ice breaker" monopile foundations designed to reduce ice loading. The project will be installed on Lake Erie, seven miles off the coast of Cleveland.

  • Seattle, Washington-based Principle Power plans to install five semi-submersible floating foundations outfitted with 6-megawatt direct-drive offshore wind turbines. The project will be sited in deep water 10 to 15 miles from Coos Bay, Oregon. Principle Power's semi-submersible foundations will be assembled near the project site in Oregon, helping to reduce installation costs. 

  • Dominion Virginia Power of Richmond plans to design, develop, and install two 6-megawatt direct-drive turbines off the coast of Virginia Beach on innovative "twisted jacket" foundations that offer the strength of traditional jacket or space-frame structures but use substantially less steel.
After the first phase, the DOE Wind Program will select up to three of these projects to advance the follow-on design, fabrication, and deployment phases to achieve commercial operation by 2017. These projects will be eligible for up to $47 million over four years, subject to congressional appropriations.

Maine PUC declines to OK Statoil offshore wind term sheet

Thursday, October 4, 2012

Today the Maine Public Utilities Commission declined to approve a term sheet offered by Statoil North America, Inc. for a long-term power purchase agreement from its proposed Hywind Maine floating offshore wind project.

Sutton Island, Maine, about 80 miles downeast of the proposed Hywind Maine project.
In 2010, Maine enacted a law designed to support the development of offshore wind and other marine renewable energy projects.  Among other features, that law required the state Public Utilities Commission to conduct a competitive solicitation for proposals for deep-water offshore wind energy pilot projects, meaning grid-tied floating wind projects at least 10 nautical miles offshore.  The statute gave the commission authority to direct mainland utilities to enter into power purchase agreements with one or more responding developers if certain minimum criteria were met.  This authority was discretionary, meaning the commission could choose not to order the utilities to sign a deal even if it met those criteria.

In September 2010, the commission issued its request for proposals under the program. Over the ensuing years, Statoil emerged as the apparent leading respondent, proposing the "Hywind Maine" project, a four-turbine, twelve megawatt project south of Boothbay Harbor.  Commission staff and Statoil negotiated the terms of a proposed power purchase agreement, which became public this summer.  Among those terms was a proposed energy price of between $290 and $320 per megawatt-hour, escalating annually, for the first 41 gigawatt-hours of energy produced each year.

That term sheet was the subject of deliberations by the Maine commission this morning.  After two hours of discussion, two of the three commissioners had stated that they would vote against approving the term sheet.  They expressed concerns about the cost of the contract, as well as uncertainty over the deal's benefit to Maine and Maine ratepayers.

The Maine commission's action bears some resemblance to that of the Rhode Island Public Utilities Commission in 2010 when it rejected a proposed contract between utility National Grid and offshore wind developer Deepwater Wind on the grounds that $244 per megawatt-hour was not a "commercially reasonable" price.  The Rhode Island commission ultimately approved a renegotiated deal with Deepwater Wind at a comparable price.  Similarly, the Maine commission invited Statoil to revise its proposal to offer more benefits to Maine, and to present a renegotiated deal for further deliberation.  Will Statoil be able to sweeten its offer and convince the commission that its contract is a good deal for Maine?
