Verdant Power

Verdant Power is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Verdant Power rather than just read about it. In short: Verdant Power, Inc is a maker and installer of tidal power and hydroelectric systems. Their primary device is an underwater turbine, similar to a three-bladed wind turbine, that is designed to capture energy from tidal currents and (precipitation-driven) river currents.

Key takeaways

Verdant Power belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Verdant Power to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Verdant Power, Inc is a maker and installer of tidal power and hydroelectric systems. Their primary device is an underwater turbine, similar to a three-bladed wind turbine, that is designed to capture energy from tidal currents and (precipitation-driven) river currents. The company uses the trade term "kinetic hydropower" to distinguish their systems from those (tidal and hydroelectric) based on dam construction. The company's first project, the Roosevelt Island Tidal Energy Project, is several turbines in New York City's East River.

Location Verdant's home base is situated between Manhattan and Queens on Roosevelt Island in the middle of the East River, a tidal strait running from Long Island Sound to Upper New York Bay.

RITE Project

The Roosevelt Island Tidal Energy (RITE) Project, owned by Verdant Power, is the first tidal energy project to be issued a license from the Federal Energy Regulatory Commission (FERC). The project is located to the east of Roosevelt Island in the East River, with the southernmost turbine approximately 100 metres (330 ft) north of the Roosevelt Island Bridge. The first of three phases of the project was prototype testing from 2002 until 2006 when the phase 2 demonstration began. The first two prototypes were installed in late 2006 and early in 2007, although these were not fully successful. In May 2007, six full-scale tidal turbines were installed on the river bed, in three rows approximately 100 feet (30 m) apart, five of which were fitted with a 35 kW generator. This constituted the "world's first operation of a grid-connected tidal turbine array". They provided power for a Gristedes supermarket and the adjacent Motorgate parking garage on Roosevelt Island. This test concluded in October 2008, having generated around 50 MWh of electricity. In February 2012 the federal government announced an agreement with Verdant Power to install 30 tidal turbines in the channel, then projected to begin operations in 2015 and produce 1.05 MW of power. There were problems with turbine blade degradation. A September 2012 test of a newly designed 16-feet diameter turbine was a success, and the company estimated it will take about 5 years to complete the array of 30 turbines in the river. In August 2013, CBS News reported that Verdant planned to put "two more turbines in the river over the next year or two and build up from there". A "TriFrame" platform with three 70 kW fifth generation (Gen5) turbines was installed in October 2020, providing power to Con Edison's local grid. After six months, one of the turbines was replaced with a new Gen5 turbine with thermoplastic blades developed by NREL. EMEC conducted an assessment of the turbines following the relevant International Electrotechnical Commission standard, "62600-200: Electricity producing tidal energy converters – power performance assessment".

Morlais project In a joint venture between with Duggan Energy, named Verdant Isles, there are plans to deploy grid-connected turbines at the Morlais site in northwest Wales. Verdant Isles was awarded a Contracts for Difference in September 2023 to supply electricity to the GB grid, which will form phase one of the project, with 4.9 MW to be commissioned by 2027/28.

Worked examples

Example 1 — a first encounter with Verdant Power

Start with the simplest possible case. Write down what Verdant Power claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Verdant Power before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Verdant Power ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Verdant Power

In research: Verdant Power appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Verdant Power in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Verdant Power is common in secondary-school and first-year university syllabi. It links to neighbouring topics Hydroelectricity in the United States, Renewable energy stubs, Renewable energy technology companies, so understanding it makes those chapters shorter.
In everyday life: Look for Verdant Power outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
