Permanent Magnet Technology: The Wind Industry's New Drive Train Standard
As PMG+FPC drive trains outperform DFIGs from both a full-cycle cost-efficiency and reliability perspective, the turbine manufacturing industry needs to revise some of its old assumptions and obsolete turbine technology choices to embrace the generator technology that leads to better AEP.
The Birth of Thermodynamics
Here is an account of something I stumbled upon on a visit to Munich last year which I hope will be of interest. The four laws without which nothing whatsoever throughout the universe that happens, happens.

This Solar Power Plant Can Run All Night
Justin Worland for Time: Crescent Dunes looks and sounds a bit like an invention lifted from a science fiction novel. Deep in the Nevada desert more than 10,000 mirrors—each the size of a highway billboard—neatly encircle a giant 640-foot tower. It looks like it might be used to communicate with aliens in deep space.
But the engineers and financiers behind the facility, located in the desert about halfway between Las Vegas and Reno, say the power plant’s promise is anything but fiction. The solar power facility built and operated by the company SolarReserve can power 75,000 homes. What sets it apart from other big solar projects is that this plant can store power for use when it is most needed, including cloudy days and after dark—a major advance for renewable energy technology.

SunEdison Files for Chapter 11 Bankruptcy Protection
PEG BRICKLEY and ANNE STEELE for The Wall Street Journal: Solar-energy Company SunEdison Inc. on Thursday filed for chapter 11 bankruptcy protection, a dramatic move for a company whose market value stood at nearly $10 billion in July.
SunEdison said its publicly traded entities, TerraForm Power Inc. and TerraForm GlobalInc., aren’t part of the filing. The two so-called yieldcos—separate entities that buy operating projects from developer SunEdison and pay out cash flow to their shareholders—said Thursday they believe they have sufficient liquidity to run their businesses and meet financial obligations, although SunEdison’s bankruptcy “will present challenges.”
Bankruptcy has been a near-certainty for SunEdison for some time. The company borrowed heavily to buy up wind and solar developers, accumulating a pile of debt that worried investors. Disappointing earnings didn’t ease their fears about the pace of SunEdison’s growth, and an accounting move last year that reclassified more than $700 million worth of debt heightened anxieties.

What is Hydropower in a Pipe?
According to the US Geological Survey, 66% of public water comes from surface water. Presumably some of that is pumped at some point, but even if only half of that were gravity fed, the potential for electricity production from municipal water pipes is significant.
Manage Costs and Risks With Long-Range Probabilistic Weather Forecasts
Deterministic weather forecasts have their place, but probabilistic forecasts are the clear choice for alternative energy companies that take the weather seriously and need long-term data.

PTEC, A WORLD LEADING TIDAL POWER PROJECT, RECEIVES APPROVAL
The Marine Management Organisation (MMO) has today granted its approval of the offshore elements of PTEC, a transformational 30MW tidal power project. The onshore part of the project was approved by the local planning authority last year. PTEC is now the largest consented tidal stream energy project in England and Wales.

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer
HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
