Managing Water and Steam Chemistry with Minimal Staff: Part 2
Some chemistry upsets have been known to cause massive failures within a matter of days and even hours
IEC/IEEE Standard to Improve Substation Operation
Communication between equipment and systems for the electric grid is an essential element of power utility automation, and central to the introduction of smart grids.
Methane from Lake Boosts Power Production in Rwanda
Elevated methane levels are harnessed in a 26 MW power plant.
Smart Sensors Identify When Motors Needs Servicing
The smart sensor provides information on parameters such as vibration, temperature and overload—and calculates power consumption.
Remote Sensor May Reduce Unplanned Motor Outages
The sensor attaches to a low-voltage motor, converting it into a machine that can monitor temperature, vibration, run time and other parameters.
Solar Industry Transitions to 1,500-Volt DC Systems
In these higher-voltage projects, BOS requirements are lower and strings are longer—allowing for fewer combiner boxes, less wiring and less trenching—all of which drive PV system costs down.
Multi-rotor Wind Turbine Undergoing Tests
The economics and output of wind energy systems may improve with a multi-rotor turbine design.
Protecting the Grid by Bolstering Cybersecurity
Through research initiatives and more robust standards, the U.S. aims to better protect against cybersecurity and resiliency vulnerabilities in the electric power grid.
Electric Microgrid to Keep Military Base on Mission
A trash-to-energy system powering a microgrid will provide energy security for a Hawaiian military base.
Wave Energy: Chasing the Big One
The U.S. Department of Energy is trying to nudge wave energy toward a design convergence with its Wave Energy Prize program.
Bifacial Solar Modules Ready for U.S. Tests
Real-world testing of SolarWorld’s bifacial Bisun modules will soon be underway in Virginia.
Don’t Neglect Closed Cooling System Water Treatment
CCW systems often reside in the background and can be forgotten when it comes to monitoring and treatment upkeep.
Global PV Installations to Exceed 310 GW: IHS
Installations are forecast to grow 17% in 2016, even as European markets slow.
Batteries to Help Transit Put Brakes on Energy Loss
Constellation will fund, own and operate the network, which brings the agency's total battery storage capacity to more than 10 MW.
NREL Develops System to Wall Off Smart Grid from Hackers
The two-way communications technologies work like an independent "electricity-only internet" with access restricted to utilities.
Piezoelectric Device Generates Energy from Gravity
The energy yield from the so-called Piezo method, which converts mechanical pressure into electrical energy, is increased from 20% to 80%.
Types of Diodes, Their Characteristics and Applications
A semiconductor diode is a non-linear device whose most outstanding feature is the fact that, basically, current is only allowed to flow in one direction.
Bruce Power to Refurbish Six Nuclear Reactors
The agreement takes effect Jan. 1 and will allow Bruce Power to invest in life-extension activities for Units 3-8.
Chaotic Motion Device Aims for Scalability, Portability
A UK firm developed a device to provide power from a few watts to hundreds of kilowatts depending on the scale of the motion source.
Silicon Anodes Boost Lithium Batteries' Energy, Researchers Claim
Silicon anode materials have a much higher capacity for lithium and are capable of producing batteries with almost 10 times more energy.
