Biomass | Stratton Biomass Power Plant

The Stratton Biomass-to-Energy facility is owned and operated by ReEnergy Holdings LLC, an Albany, N.Y. based renewable energy company. The power plant has a generating capacity of 48 MW and is located in Franklin County, Maine.

The biomass facility has been in operation since 1989 and generates renewable energy from responsibly harvested green forest residue biomass and unadulterated wood. If this material were to be left in place it would be permitted to decompose on forest floors or in urban lots where it would be producing methane gases.

Stratton Biomass Power Plant

The Stratton plant has had a good history of being an efficient wood-fired plant that has an excellent operating history. It is a zero discharge facility and there are no instances of it having difficulty in complying with the plant’s environmental permit requirements.

The plant produces 355,000 MWh of electricity per year and is capable of providing power for 45,000 homes.

The previous owner of the power plant was Quebec-based company Boralex Inc. which acquired the facility in 1998. ReEnergy bought Stratton along with other biomass plants in December 2011. The company also owns and operates the following seven other biomass-to-energy facilities throughout Maine, New York and Connecticut: Ashland, Black River, Chateaugay, Fort Fairfield, Livermore Falls, Lyonsdale and Sterling.

Together the biomass facilities owned and operated by ReEnergy have the capability of producing 296 MW of renewable energy.

Nautricity To Deploy Tidal Devices In Scottish Waters

A full scale tidal array in Scottish waters is drawing closer to reality for Glasgow-based renewable energy company Nautricity.

Consent has been given by Marine Scotland for the deployment of the first Contra Rotating Marine Turbine device, otherwise known as CoRMaT, in the Irish Sea, south of Machrihanish, Argyll. The device has been developed by Nautricity and has gone through a process of upscaling as it is taken through its various levels of testing.

Unique Tidal Technology

Nautricity CoRMaT DeviceThe first commercial scale CoRMaT device has been built over the last 18 months. It has a rotor span of 10 metres which is significantly larger than early test models. The device is more compact and lighter than the more conventional tidal devices and so the deployment and engineering costs are lower making it a cost-effective method of harnessing tidal energy.

The company has had the benefit of a £250,000 Smart Scotland grant from Scottish Enterprise and has also developed and patented its unique HydroBuoy station keeping technology. This is a tethered based mooring system to help keep the CoRMaT devices steady in strong currents.

With the shape of the wing of an aircraft, the buoy combines displacement buoyancy with hydrodynamic lift to vary mooring tension proportionally, according to the strength of tidal speeds.

The CoRMaT devices are held in tension by a subsurface float and can be deployed in a range of water depths of up to several hundred meters deep. The contra-rotating rotors are closely spaced and due to the fact that they move in opposite directions, they remain steady in the face of strong tidal flows. The result is that each device “flies” from a simple tensioned mooring. The devices can then maintain optimum alignment into the tidal flow and will vary their direction for maximum energy capture.

Work Will Start Soon

Nautricity is the fourth company to be granted full permission to deploy tidal devices in Scottish waters. Approval has also been given by Argyll and Bute Council for the construction of an onshore substation to provide a connection to the national grid.

The work on the substation is expected to start late in 2014 and the devices should be deployed in the water in early 2015.

It was only recently announced by the company that it was on track to become the first tidal energy developer to produce commercially viable electricity.

The testing of the full-scale device in real-life conditions is an important step forward and should play a vital role in proceeding to full commercial deployment. The data gathered from this stage is expected to cover much of the potential problem areas.

The Word From the Nautricity CEO

Cameron Johnstone is the co-founder and CEO of Nautricity and believes that the company could have a multi-megawatt array in place sometime after 2016.

“Once we have demonstrated the technology here and shown that it can provide affordable electricity, we will then build out to multi-megawatt arrays at home and overseas. In order to be able to compete abroad in the future, it’s essential that we have a robust, indigenous market from which to launch our international business development,”

“We believe we are doing all of the right things in developing lower cost, next-generation technology, through our progressive testing program and gathering the data to ensure that we are taking to market a product that works and can compete with other forms of energy generation.”

“Receiving full consent for this project is a great vote of confidence in our technology and our site development capabilities”.

When the turbines are deployed they are completely submerged and not visible from the shore. They will have no measurable adverse impact on the marine environment.

How the CoRMaT Works

The following is an explanation from Nautricity of how the CoRMaT works and why it is a more efficient method of harnessing tidal energy.

Nautricity CoRMaT Components

The CoRMaT second generation tidal turbine is innovative and proven technology employing two closely spaced contra rotating rotors, driving a contra rotating electrical generator. The first rotor has three blades rotating in a clockwise direction while the second rotor, located directly behind the first, has four blades rotating in an anti-clockwise direction.

This doubles the relative rotational speed compared with a single rotor turbine, allowing the turbine to directly drive a flooded, permanent magnet, contra-rotating generator, without a gearbox. The flooded generator is cooled passively by the water, eliminating parasitic energy losses associated with gearbox driven water tight active oil based gearbox-generator cooling systems and power absorbing shaft seals.

The magnetic field acts across the rotor and rotating-stator sections of the generator as a “differential”, equally splitting the torque between the two rotors. Reactive torque acting on the supporting structure is eliminated allowing the system to be moored rather than rigidly attached to the seabed.

This enables the turbine to be deployed in water depths from 8m – 500m. Buoyancy chambers at the front and rear sections of the nacelle are tuned to achieve neutral buoyancy. The turbine is connected to a tensioned mooring at a point in the water column where the flow velocity is greatest and surface wave action minimized. Tidal flow induced drag forces ensure that the turbine remains perpendicular to the flow at all states of the tidal diamond, resulting in maximum energy capture.

Historic House Plas Newydd Warmed By Tidal Energy

Tidal energy is being used to convert the currents of the Menai Strait into heating for the Plas Newydd Mansion in Anglesey. The National Trust property in North Wales will be equipped with a 300kW pump.

The way it will work will be to pump a small amount of seawater through pipes to a heat exchanger on shore. The water will then be sent up a 30 metre cliff face to the mansion’s boiler house.

The system uses electricity to work the exchanger and then the pump and the final heat is produced at a relatively low temperature. In the case of Plas Newydd it will only reach 55C but this is ideal for maintaining a temperature for the building’s conservation.

Plas Newydd

Up Front Cost and Anual Savings

The pump cost the National Trust £600,000 and will save around £40,000 in annual operating costs. The system will also remove the mansion as the Trust’s most polluting property, removing its dependence on oil for heating.

By using the pump the CO2 performance and money savings each year will be returned to the upkeep of the mansion.

The pump used for this project was manufactured by Stiebel Eltron UK and installed by Kimpton Energy Services. More than three years of planning and implementation have gone into its commissioning.

More than 40 people have worked on the project which has proven to be both complex and challenging in terms of operating around the tides and getting equipment into and out of the site. The design also had to meet the criteria of the Government’s Renewable Heat Incentive (RHI) which stipulates specific performance requirements.

Enthusiasm About the Project

Paul Southall, an Environmental Advisor at the National Trust, said: “The installation of the marine source heat pump at Plas Newydd forms part of the National Trust’s Grow Your Own Energy programme which includes targets of reducing energy usage by 20 per cent and meeting half of our energy requirements through renewable energy. The vast amount of money we were spending on heating Plas Newydd with oil is money that we were not able to spend on conservation.

“This project has seen a number of firsts – the first marine source heat pump of its type in the UK, the biggest at 300kW and the first in open sea rather than a harbour. What has been done is genuinely cutting-edge and I have nothing but praise for Stiebel Eltron and Kimpton who were faced with the unique challenge of designing and installing the heat pump. Considering the scale of the project, everything has gone remarkably smoothly.”

Adam Ellis-Jones, Assistant Director for Operations in Wales for the National Trust, said: “With the Irish Sea right on the doorstep of Plas Newydd, a marine source heat pump was the best option for us. However, being a pioneer is never easy. There are very few marine source heat pumps and nothing of this size in the UK, so it has been a challenging project but a very exciting one.”

The use of heat pumps is not a universally suitable option for all properties. It is an option that works for places like Plas Newydd because it was not connected to the gas grid and relied on expensive oil heating.

Project In New York Will Put Vanadium Flow Batteries to the Test

The possibility of utility-scale energy storage has been brought even closer to reality with the improvement and refinement of flow-battery technology that relies on vanadium.

The technology of vanadium flow batteries has been validated with an announcement by New York State Energy Research and Development Authority (NYSERDA) that it will partner with energy storage company American Vanadium. The partnership will undertake a demonstration project that will use a CellCube vanadium redox flow energy storage system.


“This is not a technical demonstration, it’s to analyze how we can shift energy around during peak load periods,” American Vanadium President & CEO Bill Radvak explains. One of the interested parties is Con Edison, a partner in the project, who is seeking a means of expanding its demand response efforts so that the management of the electricity flow is controlled through the grid during peak demands.

The way in which the CellCube is used will be as a supplementary energy source in an automated demand response system. This system has been developed for a 1.6 million square foot New York City office building.

It is expected that the project is going to demonstrate how the use of this type of battery technology will allow commercial buildings to act smartly when using energy.

A new incentive system has been proposed by Con Ed for products that provide summer on-peak demand reduction. The incentives amount to $2,100/kW for battery storage systems.

Vanadium redox flow batteries are more effective when compared to lithium-ion storage because they provide long-duration storage. A lithium-ion battery will only last for around an hour.

Using a flow battery will also lower electricity costs. This is done by only charging the systems at night when the rates are lower. During the daytime the stored energy can be used to automatically reduce daily peak loads.

“New York is clearly creating a leading energy storage marketplace and the knowledge gained from this demonstration will help realize gains in building and grid energy efficiency, save money for electric ratepayers and, importantly, add a new weapon to the arsenal of resiliency tools in the event of future grid outages,” Radvak said in a statement

Sensor Platform Built to Understand Fundy Tides

A key for the development of tidal power projects in the Bay of Fundy is a better understanding of the powerful tides. This understanding will be substantially improved by an advanced sensor platform that is being built for the Minas Passage.

The platform is being developed by The Fundy Ocean Research Center for Energy (FORCE). When it has been completed it will be able to be used to get constant up to the minute information about the tidal currents at the FORCE site.

The platform will measure the tide, current flow and water quality and the information will be relayed back using a 3-kilometer subsea data cable. This cable has been in place since 2013.

Minas Passage

Tony Wright, general manager of FORCE, said: “The platform builds on the successful deployment last year of the first subsea cable ever laid in the Minas Passage – a task that proved we can work in the world’s most challenging tidal site.”

The platform is part of FORCE’s Fundy Advanced Sensor Technology (FAST) program. This program has been devised to monitor the FORCE site and requires a recoverable platform that has onboard sensory equipment.

The platform project manager for FORCE is Simon Melrose and he was recently speaking at the Nova Scotia Energy Research and Development Forum where construction contracts were announced. He pointed out that before the power of the Bay of Fundy could be harnessed it needed to be understood.

FORCE general manager Tony Wright said: “We expect most of this work will be carried out by local firms – proving that Nova Scotia and Canada already have the expertise to lead this industry.”

Local companies that are involved in the operation include Open Seas Instrumentation from Musquodoboit Harbour is designing and building the platform, while EMO Marine Technologies from Eastern Passage is designing and building the communication system that will bring the data ashore via the fibre optic data cable. Mackenzie Atlantic Tool and Die is also based in Musquodoboit Harbour and is building the specialised stainless steel housing for the equipment.

There is already a great deal of interest in the Bay of Fundy by many parties, notably those involved in the Maine Tidal Energy Project.

Local Business Supports Swansea Bay Tidal Lagoon

The Swansea Bay Business Club has conducted a survey amongst local businesses to gauge support for the newly proposed Swansea Bay Tidal Lagoon and the results have been very positive.

According to the club president and secretary Bruce Roberts the local companies completely recognise that there is a need for secure alternate energy supplies. The club itself gave its formal support to the scheme following the overwhelming support given by its members.

“Every business that took part in a survey by our policy group saw the lagoon as a positive development that would bring economic and regenerative benefits to the bay region,” said Mr Roberts.

“Local companies saw significant economic benefits for the region from major schemes like the tidal lagoon.”

Swansea Bay Tidal Lagoon Walk

Swansea East MP Sian James has also been getting a feel for how the scheme is being received by her constituents and has found that the local reaction has been very positive.

“The feedback I get from constituents — and these are the people who matter — is that the lagoon will be good for Swansea,” she said.

“Many who have attended the briefings say they were impressed with the attention paid to environmental issues.”

The only vocal opponent of the scheme so far has been Swansea West MP Geraint Davis who believes the lagoon would harm tourism and views of the bay.

The Swansea West MP said: “It would be a catastrophic mistake setting aside legitimate concerns over contamination of Swansea Bay and the depopulation of the Gower and its sands.”

Anyone who is interested in the project will be able to attend a preliminary meeting that is going to be held at the Dylan Thomas Centre on June 10. This will give everyone a chance to get a closer look at what is going to be the biggest ever construction project for Swansea.

This preliminary meeting marks the start of an examination process which could last for up to six months.

A local impact report must be filed by Swansea Council by July 8 and this is currently being completed.

More information about the project can be found in the earlier article: Swansea Bay Tidal Lagoon Plan Submitted.

Shetland Seabed Tidal Turbine Generating Electricity

The newest tidal turbine has been put into operation at a depth of 100 feet on the seabed in the Bluemull Sound in Shetland. This location sits the device between the islands of Unst and Yell. The turbine is the Nova 30 tidal turbine and has been developed by the Leith-based tidal energy company Nova Innovation.

The project that is responsible for this new step in tidal power production has been brought about by a partnership between Nova Innovation and North Yell Development Council. Funding has been provided by the Scottish Government’s Community and Renewable Energy Scheme (CARES), Shetland Islands Council and North Yell Development Council.

The electricity generated by the propeller mounted on the turbine is generated as the tide ebbs and flows. This drives a generator and the electricity that is produced is transmitted back to shore via a 1km subsea cable.

The Nova 30 Tidal Device

AR1500 Tidal Turbine

The Nova 30 is a 30kW device and this single device, when in full operation is capable of generating 30kW of electricity, essentially this is enough electricity to power up to 30 homes. In the case of this particular turbine it is also providing power to 30 homes, an ice plant and Cullivoe Harbour Industrial Estate.

The significance of the connection of the Nova 30 to the grid is that it has become the world’s first community-owned tidal turbine to provide commercial power.

Comments from the Management

Details of the project have been presented to the All-Energy Conference in Aberdeen by the Scottish energy minister, Fergus Ewing who has confirmed that the project is now producing power.

Ewing stated that “For the first time, anywhere in the world, a community-owned tidal turbine is generating electricity. It will have a positive impact on the North Yell community and economy.”

Nova’s managing director Simon Forrest also expressed his delight at the successful deployment of the device.

“It marks a major achievement for the wider Scottish tidal industry with over 80 per cent of Nova’s supply chain Scottish-based,” Forrest said.

“By working in close partnership with the North Yell community and our suppliers, we believe that this project demonstrates the growing confidence in the marine sector and strengthens Nova Innovation’s leading position in the emerging global marine energy industry.”

Bigger Plans For the Future

This is a significant step in the development of technology in the tidal power industry and could pave the way to a more significant array. Nova Innovations is also developing the scaled up version of the deployed Nova 30 in the form of the Nova 100.

The company has already secured a Crown Estate lease and permits to install five Nova 100 devices as an array and will become one of the first in-sea tidal arrays in the world.

Secondary Permits Requested For Tidal Power In Cobscook Bay

The Bangor Daily News has reported that there are two proposals for dams to be built in Maine in the greater Cobscook Bay for the purpose of harnessing tidal currents. Both of these proposals are in the process of going through the federal regulatory process.

The first is a project that has been brought forward by Pennamaquan Tidal Power under the name Halcyon Tidal Power. The company would like to build a tidal barrage that will measure 1,616 feet across the Pennamaquan River between Leighton Neck and Hersey Neck south of Pembroke. This project has been estimate as costing $120 million.

The second is a request for approval from Tidewalker Associates who are looking to build a 1,200 foot long dam in Half Moon Cove. This project is being operated under the name Maine Tidal Power and would be located between Eastport and Pleasant Point.

In both cases the initial permits have expired and they are seeking successive preliminary permits to continue.

According to the preliminary permit application, the Pennamaquan Tidal Power project proposal consists of:

  1. A new tidal barrage extending from Leighton Neck to Hersey Neck consisting of:
    (a) Two 5-foot-thick concrete walls, one 545-foot-long and one 135-foot-long, located in the intertidal area at each end of the barrage;
    (b) six 82-foot-long, 10-foot-thick concrete modular wall panels extending about 22 feet above mean low tide;
    (c) a new 438-foot-long, 91-foot-high concrete powerhouse with 16 reversible bulb generating units with a total capacity of 24.0 megawatts;
    (d) a new steel 65-foot-long, 44-foot-wide boat lock integral with the powerhouse;
  2. a tidal basin (i.e., impoundment) with a surface area of 489 acres at low tide and 862 acres at high tide;
  3. a new 328-foot-long utility road providing access from Hersey Neck to the powerhouse; and
  4. a new 35 kilovolt, 2.5-mile-long transmission line to Emera Maine’s substation in Pembroke, Maine.

The following is an artists impression of what the tidal barrage will look like.

The preliminary permit application that was lodged by Tidewalker Associates for the Half-Moon Bay area consisted of the following:

  1. A new 1,200-foot-long rock-filled barrage with a crest elevation of approximately 27 feet above mean sea level (msl);
  2. a new 30-foot-wide, 15-foot-high filling and emptying gated section;
  3. the 850-acre Half-Moon Cove with a surface elevation of 13.0 feet above msl;
  4. a new powerhouse with four turbine generating units with a total capacity of 9.0 megawatts; and
  5. a new 34.5 kilovolt, 7.1-mile-long transmission line.

Below is an artists impression of what the Maine Tidal Power barrage will look like when it is in operation.

The environmental impacts of the proposed projects are determined during this permitting process. The initial preliminary permit was valid for three years which was not long enough for the initial planning phase of the environmental impact study to be completed.

Should both of the projects gain approval to go ahead with their plans the estimates for future renewable energy power production are good.

The Pennamaquan Tidal Power project has estimated that the facility will be capable of generating 80,000 megawatt hours of electricity per year. This would be enough to provide power to 13,000 homes. The Half Moon Cove project would be capable of generating around 40,000 megawatt hours.

Swansea Bay Tidal Lagoon Plan Submitted

A six-mile long U-shaped seawall has been planned with an estimated cost of £850m for Swansea Bay to create a new tidal lagoon. The project has been proposed by Tidal Lagoon Swansea Bay Ltd and could provide power for 120,000 homes.

The seawall will extend from Swansea docks to the new Fabian Way campus of Swansea University. Construction will take two years and will create 1,850 construction jobs. Once it has been made operational the facility will generate 60 long-term jobs.

The expectation is that the lagoon will have a 240MW nominal rated capacity and average 14 hours of electricity generation per day.

It is hoped that the tidal project will be operating by 2018.

The seawall would create a lagoon and it will be capable of holding 11 square kms of water. The water would be held and then let out through turbines at both high and low tides with electricity being generated at this time.

Water would flow from the lagoon into the sea at low tide and from the sea into the lagoon at high tide.

Mark Shorrock, chief executive of Tidal Lagoon Swansea Bay, said: “Until now, tidal energy has been heavily promoted by governments and environmentalists as an intuitive source of clean and reliable energy for our island nation, but the business response has focused on relatively small-scale tidal stream devices.

“The UK has the second highest tidal range in the world and today we are submitting an application for a development that will prove that this resource can be harnessed in a way that makes economic, environmental and social sense.

“Tidal lagoons offer renewable energy at nuclear scale and thus the investment of hundreds of millions of pounds in UK industries and coastal communities.”

Visitor Centre

Swansea Bay Visitor Centre

Part of the development will include the creation of a new visitor centre as well as a national triathlon and water sports facility. The visitor centre is proposed with a very distinctive oyster shell shaped design and it would be sited at the end of the lagoon’s seawall.

The Planning Inspectorate will scrutinise the case initially, but because of the size of the project exceeds 100 megawatts the UK government’s Energy Secretary Ed Davey has the final say as to whether it will go ahead.

According to the developer, research as part of the project’s initial stages found that 86% of local residents were in favour of the scheme.

Friends of the Earth (FoE) Cymru and Wildfowl and Wetlands Trust have backed the plans.

Gareth Clubb, from FoE, said: “Provided they meet strict environmental criteria, tidal lagoons can play a key role in building a low carbon future, supplying clean electricity to many thousands of homes.

“With its huge coastline, the UK has plenty of potential for developing more schemes like this, along with other renewable forms of energy.”

Lockheed Martin To Enter Tidal Technology With Atlantis Resources

Tidal energy developer Atlantis Resources will soon see the commencement of optimization services for its AR 1500 turbine. The security and aerospace company Lockheed Martin has begun work on a contract with the developer.

The turbines will have 1.5MW capacity and will feature a large single-rotor turbine with an active rotor pitch and full nacelle yaw rotation. They are going to be installed in a couple of projects on either sides of the Atlantic at the MeyGen project in the Bay of Fundy in Canada and at Scotland’s Pentland Firth.

Here is a copy of the announcement that was released by Lockheed Martin which explains the agreement between the two companies.


New contract highlights Lockheed Martin’s continued role as leader of ocean energy

BALTIMORE, March 18, 2014 – Adding to its recent momentum in ocean energy, Lockheed Martin announced today that it is further advancing the next generation of tidal energy Lockheed Martin has commenced a contract from global tidal energy leader Atlantis Resources Ltd. (ARL:LN) to optimize the design of Atlantis’ new 1.5-megawatt tidal turbine, the AR1500.

Designed to facilitate operation in highly energetic tidal locations, the AR1500 turbine will be one of the largest single rotor turbines ever developed and will have active rotor pitch and full nacelle yaw rotation. The increased capability and integrated, advanced functionality will help bring commercial tidal energy to reality, and will initially support the MeyGen project in Scotland’s Pentland Firth and deployment in Canada’s Bay of Fundy. Once completed, the MeyGen project – the world’s largest tidal stream project under development – is expected to deliver up to 398 megawatts of power, enough energy to power 200,000 homes. The MeyGen project will contribute to Scotland’s goal of 100 percent renewable energy by 2020.

“By 2040, world energy demand is expected to dramatically increase,” said Tim Fuhr, director of ocean energy for Lockheed Martin’s Mission Systems and Training business. “Lockheed Martin’s technology, development and expertise in ocean systems and global system integration skills will enable the AR1500 to use powerful tides to produce safe, clean renewable energy for homes and businesses around the world.”

Tidal turbines work like an underwater wind turbine. The tides’ ebb and flow force the blades to spin, which rotate the turbine and activate a generator that produces electricity. Tidal energy’s greatest advantage over other alternative energy sources, such as wind power and solar energy, is that it is almost entirely independent of the weather. The movement of the tides can be accurately forecast for many years into the future.

“With us acquiring the MeyGen project, and receiving full consents to begin construction of the project’s first phase, it has been an amazing 12 months of growth for Atlantis,” said Tim Cornelius, chief executive officer of Atlantis Resources Ltd. “Our AR1500 development program with Lockheed Martin will ultimately deliver the rapidly growing tidal energy industry the most advanced, robust and powerful tidal turbine system available on the market.”

Last year, Lockheed Martin and Atlantis entered into an exclusive teaming partnership to develop technology, components and projects in the tidal power sector on a global basis. The new AR1500 tidal turbine Lockheed Martin is designing is expected to be one of the most technologically advanced and robust turbines ever produced. The two companies have been working together for four years, most recently on the delivery of the Energy Technologies Institute TEC Demonstrator program, which is aimed at bringing a step-change reduction in the cost of deploying tidal turbines in commercial arrays.

Lockheed Martin takes a comprehensive approach to solving global energy and climate challenges, delivering solutions in the areas of energy efficiency, smart energy management, alternative power generation and climate monitoring. The company brings high-level capabilities in complex systems integration, project management, information technology, cyber security, and advanced manufacturing techniques to help address these challenges. Today, Lockheed Martin is partnering with customers and investing talent in clean, secure, and smart energy – enabling global security, a strong economic future, and climate protection for future generations.

Atlantis Resources Ltd. is a vertically integrated turbine supplier and project developer in the tidal energy industry. Atlantis holds equity positions in a diverse portfolio of tidal stream development projects, which includes 100 percent ownership of MeyGen Limited, the company developing the MeyGen project in Scotland. Alongside its project development interests, Atlantis owns a portfolio of patents and patent applications relating to tidal power generation and sells tidal generation equipment and engineering services to third party developers, as well as its own projects. As a revenue-generating organization, Atlantis also conducts industrial research and development and provides specialist consulting services globally.
