The New York Power Authority , officially the Power Authority of the State of New York, is the largest state public power organization in the United States. NYPA provides some of the lowest-cost electricity in the nation, operating 16 generating facilities and more than 1,400 circuit-miles of transmission lines. Its main administrative offices are in White Plains.NYPA uses no state tax dollars and incurs no state debt, financing its projects principally through the sale of bonds. The bonds are repaid and the projects operated using revenues from operations.State and federal regulations determine NYPA’s customer base, which includes large and small businesses, not-for-profit organizations, public power systems and government agencies. NYPA also sells electricity to private utilities for resale to their customers, and to neighboring states, under federal requirements. Approximately 70 percent of the electricity NYPA produces is clean renewable hydropower. Its lower-cost power production and electricity purchases support hundreds of thousands of jobs throughout New York State.NYPA operates three large hydroelectric complexes: the 2,441,000-kilowatt Niagara Power Project, on the Niagara River in Lewiston; the 800,000-kW St. Lawrence-Franklin D. Roosevelt Power Project, on the St. Lawrence River in Massena; and the 1,160,000-kW Blenheim-Gilboa Pumped Storage Power Project in the Catskill Mountain towns of North Blenheim and Gilboa.NYPA also has four small hydro facilities with a net capability of 10,000 kW: the Ashokan Project in Ulster County, the Crescent Plant in Albany and Saratoga counties, the Gregory B. Jarvis Plant in Oneida County and the Vischer Ferry Plant in Schenectady and Saratoga counties.Other generating facilities include two highly efficient and clean natural gas-fueled power plants: the 135,000-kW Richard M. Flynn Power Plant, in Holtsville, Long Island and a 500,000-kW facility, in Astoria, Queens.Additionally, NYPA operates seven small, clean power plants also fueled by natural gas. Those units – six in New York City and one on Long Island – combine for 461,000 kW.The hub of NYPA’s statewide power transmission facilities is the Frederick R. Clark Energy Center, in Marcy. NYPA’s high-voltage transmission assets include a 765-kilovolt line that stretches more than 100 miles from the Canadian border to the Clark Energy Center and almost 1,000 miles of 345-kv power lines that crisscross New York State, including a 26.3-mile transmission project that follows an underground and underwater path from Westchester County to Long Island.

Venture capitalists invested $58.8 billion into U.S.-based startups in 2015, according to Thomson Reuters, PwC and the National Venture Capital Association -- the second-highest figure recorded. But VCs continue to turn a blind eye to the cleantech sector -- with less than $700 million invested in the last quarter of 2015, according to Clean Energy Pipeline, and just a fraction of that total going to early-stage deals. Nevertheless, we've managed to find eight earlyish-stage cleantech deals to start off 2016. Powerhive, a microgrid developer and financier for emerging markets, closed a $20 million series A financing round led by Prelude Ventures along with Caterpillar Ventures, Total Energy Ventures, Tao Capital Partners and Pi Investments. The funding will be used to grow Powerhive’s footprint into new markets in Africa and the Asia-Pacific region, as well as to support continued expansion in Kenya. Recently, Powerhive received a $12 million equity investment in its flagship project, which is seeking to develop microgrids that will serve 90,000 people in western Kenya. The Berkeley, Calif.-based company has offices in Nairobi and Manila, and received early backing from First Solar. Off-grid renewable energy companies raised close to $200 million in 2015 versus the roughly $64 million invested in off-grid solar solutions in 2014. MPrest just raised $20 million in equity funding led by GE Ventures and OurCrowd in its series A. The startup provides software to “connect the dots” across "multiple complex systems of any scale for real-time situation awareness [and] predictive analytics" and is bringing its technology to the internet-of-things/utility market. The firm is already working with New York Power Authority and Israel Electric Corp. The company has also contributed to Israel's "Iron Dome" defense system. London-based Telensa, a 10-year-old developer of networked LED street lighting equipment for "smart city" applications, raised $18 million in equity and debt from Environmental Technologies Fund and Silicon Valley Bank. Telensa already has hundreds of thousands of endpoints networked using its low-power wide-area wireless technology. The company is a founding member of the Wireless Internet of Things Forum. Mercatus, a cloud-based provider of "Energy Investment Management" (EIM) solutions to energy producers, developers and financiers, raised $11.7 million in series B funding led by Traverse Venture Partners and TPG’s Alternative and Renewable Technology fund, along with existing series A investors Vision Ridge Partners, Trepp and Augment Ventures. Josh Green of Traverse said, "In the current era of rapid energy industry transformation, we see Mercatus’ EIM solution as a critical enabling technology that accelerates the mass deployment of distributed energy."  Mercatus is seeking to speed up "the investment of massive amounts of capital required by the energy industry,” according to Haresh Patel, the company's CEO. Pellion Technologies, a Cambridge, Mass.-based developer of a magnesium battery technology with a potentially high energy density, raised an undisclosed amount of funding from Motorola Solutions. Motorola joins previous investor Khosla Ventures, along with the DOE. David Eaglesham, former CTO at First Solar, is the CEO of Pellion. Small modular reactor startup Terrestrial Energy closed $8 million in funding from undisclosed sources for its Integral Molten Salt Reactor design, according to SEC documents. Terrestrial's chairman Hugh MacDiarmid is on the board of two companies financially involved with the $106 billion Ontario Teachers’ Pension Plan, suggesting their undisclosed involvement here. The small nuclear reactors are intended for industrial process heat markets, with market deployment targeted "in the 2020s." According to SEC documents, Geli, the distributed energy storage software developer, has raised $3 million of a $9 million funding round from undisclosed investors. Strategic funders will fill out the rest of the round, according to sources. Voltaiq closed on $1.6 million of a $3 million funding round, according to SEC documents. The startup is developing software to track and analyze the performance of batteries with analytics and big data. Michael Berolzheimer, an investor at Bee Partners, is listed on the SEC document. CEO Tal Sholklapper co-founded Point Source Power, a fuel-cell technology firm funded by Vinod Khosla.

With amplitude and phase information, time-synchronized measured phasor data of bus voltages and line currents can be used to calculate, without iterations, the voltage phasor on neighboring buses. In some phasor measurement units (PMUs), it has been observed that the voltage and current phasors exhibit phase biases, which can corrupt the conventional state estimator solution if it is augmented with such biased phasor data. This paper presents a new approach for synchronized phasor measurement-based state estimation, which can perform phasor angle bias correction given measurement redundancy. In this approach, polar coordinates are used as the state variables, because the magnitude and phase are largely independent measurements. The state estimation is formulated as an iterative least-squares problem, and its application to portions of the AEP high-voltage transmission system is illustrated. © 2010 IEEE.

NEW YORK (AP) -- In a story March 16 about off-shore wind energy, The Associated Press reported erroneously that a planned wind farm off New York would not be visible from shore. The Bureau of Ocean Energy Management said the turbines could be visible from certain parts of the shore in New York and New Jersey, depending on their final location and design. A corrected version of the story is below: 125 square miles off New York coast dedicated for wind power Federal officials say more than 125 square miles off the coast of Long island will be dedicated for the development of commercial wind energy NEW YORK (AP) -- Federal officials on Wednesday dedicated more than 125 square miles in the waters off the coast of Long Island for the development of commercial wind energy, pushing forward a renewable energy proposal initially created by New York utilities. Interior Secretary Sally Jewell said the state has "tremendous" offshore wind potential. "Today's milestone marks another important step in the president's strategy to tap clean, renewable energy from the nation's vast wind and solar resources," she said in a statement. The Long Island Power Authority, New York Power Authority and Con Edison initially went to the Bureau of Ocean Energy Management in 2011 with the proposal to build the farm in the Atlantic Ocean that would include up to 200 turbines generating about 700 megawatts of energy capable of powering about 245,000 homes. The price tag was estimated at between $2 billion and $4 billion. Under federal regulations, the bureau had to open the bidding up, and at least five companies expressed interest in leasing the area for wind farm projects. An environmental assessment will now be completed to determine the effects associated with developing the farms. After that, leases will be given, though it's not clear whether one company will gain access to the entire acreage. The wind farm could be visible from some beaches in New York and New Jersey, depending on scale, color, distance, weather and other factors. Environmentalists praised the designation on Wednesday. Anne Reynolds, executive director of the Alliance for Clean Energy New York said the news was a crucial step. "Today's federal action is adding to the momentum for offshore wind development in New York," she said in a statement. Conor Bambrick, air and energy director for Environmental Advocates of New York, said it sets the stage for Gov. Andrew Cuomo to carve out a "big role" for offshore wind as part of the state's clean energy standards. Late last year, Cuomo rejected a proposal to build a liquefied gas terminal in the waters off New York and New Jersey, in part because he feared it would affect the proposed wind power project. In January, the state established a $5 billion clean energy fund to encourage renewable sources of electricity such as wind and solar, part of Cuomo's plan to generate half of the state's energy from renewable sources by 2030.

The remote-controlled devices make the work of linemen safer, more efficient and less expensive, according to the Electric Power Research Institute, which last month put on a three-day workshop to help nearly a dozen utilities choose the best machines for the job. Miniature helicopter-like drones, some equipped with cameras and other sensors, conducted demonstration inspections of transmission lines at a hydroelectric plant in the Catskill Mountains. "We want to start using drones next spring when the inspection season begins," said Alan Ettlinger, research and technology director for the New York Power Authority, who attended the workshop. Utilities spend millions of dollars inspecting power lines, which are often in hard-to-reach places. The industry has been interested in the potential use of drones for years, but has been slower than European companies to adopt the technology because of U.S. regulatory restrictions. While hobbyists can fly drones without certification, the Federal Aviation Administration requires special certification for commercial users. There are numerous conditions and limitations: The drone operator needs a pilot's license, the aircraft must weigh less than 55 pounds, flights can go no more than 200 feet above the ground, and the drone must be operated in the pilot's line of sight. The FAA treats the operation of drones like any other aircraft for safety reasons and commercial operators face strict rules for getting permission to use them, according to the agency. Seven U.S. utilities have been granted FAA approval for testing drone technology in 2015. Consumers Energy in Michigan conducted a series of tests over the summer using its own eight-rotor drone and unmanned aerial vehicles operated by outside vendors to inspect wind turbines, utility poles and transformers. The utility is part of a UAV task force under the Edison Electric Institute, the association representing U.S. investor-owned electric companies. "When you look at the amount of information we can gain to make accurate decisions about our systems, and look at the cost and time savings, this is a huge opportunity for us," said Andrew Bordine, a Consumers Energy executive. The UAV system Consumers Energy uses starts at about $10,000, Bordine said. Sensor attachments range from a few thousand dollars to upward of $100,000, he said. But the cost savings are far greater than the investment. Consumers Energy spends several hundred thousand dollars a year to send people out in the field to do mapping and measuring of its electrical system, Bordine said. A UAV equipped with "lidar," the sensor technology used to develop driverless cars, can collect the same data and more at a small fraction of the cost and time. "With wind turbines, you'll have a couple of guys hanging off the blades by a rope a couple hundred feet in the air to do inspections visually, at a cost upwards of $10,000 per site," Bordine said. "We can get the same results with a UAV for $300, without putting workers in danger." The Bureau of Labor Statistics reports 17 fatal work injuries among utility workers in 2014, but doesn't specify the cause. Other industries, including oil and gas drillers, pipeline operators, construction companies, and agriculture are also investigating the use of drones to make inspection and mapping tasks faster, more accurate, safer and less costly. "The main advantage we provide in small unmanned assets is safety," said Mark Sickling, chief pilot for Cyberhawk, a drone company based in the United Kingdom that does aerial inspections for utilities and the oil and gas industry. At the workshop, Sickling demonstrated Cyberhawk's most popular drone, the eight-rotor G4 Eagle, which boasts "unprecedented flight and image stability." The work done by Consumers Energy over the summer could also be done with a drone flying without direct human control using instructions entered into an onboard flight computer if the FAA allowed it, Bordine said. "The FAA is looking at how to revamp its requirements to make the technology more accessible to more companies," Bordine said. "A goal for me would be to get FAA approval to work with a remote application and an autonomous flight." Explore further: Proposed rules for drones envision routine commercial use (Update)

This story has been updated. After years of fighting the expansion of drilling off the Atlantic coast, environmentalists scored a rare double victory this week in which oil lost ground to wind energy. In a surprising about-face, the Interior Department pulled back its controversial plans to allow oil drilling off the coasts of Virginia, North Carolina, South Carolina and Georgia. Citing concerns from the Pentagon and also from coastal communities in these states, Interior Secretary Sally Jewell said, “It simply doesn’t make sense to move forward with any lease sales in the coming five years.” Climate activists and environmentalists were ecstatic — and that was just the beginning. The next day, the department announced a move to create a large offshore wind area 11 miles south of Long Island and extending to the Southeast in the shape of a thin triangle, over some 127 square miles. It will be called the “New York Wind Energy Area.” The New York development proves “that the U.S. can move rapidly to develop clean energy sources off the Atlantic coast, rather than drilling for the dirty fossil fuels of the past,” Jacqueline Savitz, vice president for the United States for Oceana, an ocean-focused environmental group, said in a statement. The new wind energy area off the New York coast emerges in response to an initiative by the New York Power Authority, the Long Island Power Authority and Con Edison — which have formed a group called the Long Island-New York City Offshore Wind Collaborative. In 2011, the group filed an application with the federal government for a 350 to 700 megawatt wind farm in this area, in waters 60 to 120 feet deep, to directly power New York City and Long Island. It would have “the potential to be the largest offshore wind project in the country,” the collaborative said. Now, the federal government is moving ahead on the matter, although there will be a “competitive leasing process,” meaning there are other potentially interested parties in wind in the area, beyond this group. “This is a great day for New York, and our country as we continue to diversify our nation’s energy portfolio,” Abigail Ross Hopper, director of the Interior Department’s Bureau of Ocean Energy Management, said in a statement. “The area is large enough for a large-scale commercial wind project, which could make substantial contributions to the region’s energy supply and assist local and state governments — including New York City — in achieving their renewable energy goals.” The move comes as New York Gov. Andrew M. Cuomo (D) recently laid out a plan to get 50 percent of the state’s total electricity from renewables by 2030. Offshore wind will be a key piece of hitting that target, said Anne Reynolds, executive director of the Alliance for Clean Energy New York. The site is rather ideal for sending power to the huge population just a few ocean miles away, Reynolds noted. “Part of the attraction for offshore wind development in New York is that you’d have the electricity demand very nearby, and you’d have the wind peaking in the late afternoon, when you have demand peaking as well,” she said. The Interior Department has, so far, approved 11 Atlantic offshore wind energy leases, off Rhode Island, Massachusetts, New Jersey, Delaware, Maryland and Virginia. The new “wind energy area” designation does not mean that an immediate lease sale will be held for the siting of wind energy off New York — rather, the next step of the process involves an environmental impact assessment. After that, there would be the potential for lease sales. The United States remains far behind some other countries — such as Britain and China — in overall offshore wind development. So far, among other potential projects, construction has begun for Deepwater Wind’s projected 30 megawatt installation off the coast of Rhode Island. It’s expected to start operating this year. In general, offshore wind is seen as a critical new development in the wind energy area because offshore turbines can tap into stronger winds to generate larger volumes of electricity. But development has been dramatically faster on land. Wind energy provided 4.7 percent of U.S. electricity last year, according to the American Wind Energy Association, a number that has been steadily growing in recent years. The Energy Department’s “wind vision” for 2030 imagines getting 20 percent of U.S. electricity from this source. To do that, the nation will need far taller wind turbines on land — which can capture energy from more powerful winds and open up new areas to viable wind farms — and also major offshore developments.
