By Kyle Julian, Regional Director, Commercial & Industrial Sales, U.S. West Without data centers, life as we know it would collapse. That may sound like hyperbole, but our entire digital economy relies on data centers. But it turns out that data centers use a lot of electricity. In fact, the ... [continued]

In view of the problems of low accuracy, long time consuming and low efficiency of the existing engineering investment risk assessment method; this paper puts forward the investment risk assessment method of power grid construction project based on grey correlation analysis. Firstly, classify the risks of power grid construction project; secondly, determine the primary index and secondary index of investment risk assessment of power grid construction project; then construct the correlation coefficient matrix of power grid project investment risk to calculate the correlation degree and weight of investment risk index; finally, adopt the grey correlation analysis method to construct investment risk assessment function to realise investment risk assessment. The experimental results show that the average accuracy of evaluating the investment risk of power grid construction projects using the method is 95.08%, and the maximum time consuming is 49 s, which proves that the method has high accuracy, short time consuming and high evaluation efficiency.

The U.S. electric power delivery system is vulnerable to terrorist attacks that could cause much more damage to the system than natural disasters such as Hurricane Sandy, blacking out large regions of the country for weeks or months and costing many billions of dollars, says a newly released report by the National Research Council.

The present electric grids use the technology of 1970’s. But with the advancement in various concepts of power generation, problems associated with power outages and thefts, and also due to increase in demand, we require a modernized grid to avail... Read more

Requirements for distributed ledger technology-based power grid data management

Wednesday Cuba was hit by a major hurricane which took down its entire power grid again, this time for about 24 hours, according to CNN: Videos of the aftermath showed power infrastructure turned into a mangled mess and power poles down on streets. Hundreds of technicians were mobilized Thursday to reestablish power connections, according to state media... Operations at two electrical plants were partially restored and parts of eastern and central Cuba had electricity back up by Thursday afternoon, state media reported... The country's power grid has collapsed multiple times, including when Hurricane Oscar hit in October and killed at least 7 people. In the capital of Havana, where 2 million people live, power had been restored to less than 20% of the city by late Friday afternoon, . "Authorities had not yet given an estimate for when power would be fully restored..." Then tonight, CNN reported: A 6.8 magnitude earthquake struck off the coast of eastern Cuba on Sunday, causing material damage in several regions as the island continues to recover from widespread blackouts and the impact of two hurricanes over the past few weeks. The earthquake was reported about 39 km (24 miles) south of Bartolomé Masó before noon local time, about an hour after a 5.9 magnitude quake rocked the area, the United States Geological Survey (USGS) said. "There have been landslides, damage to homes and power lines," Cuban President Miguel Díaz-Canel said, adding that authorities are evaluating the situation to start recovery efforts.

A pale orange-and-gold sunset bathes the macadamia plantations and avocado orchards that sweep down to Australia’s Byron Bay. The coming dusk is a cue for two sleek Tesla battery packs in the garage at Amileka, a secluded holiday villa nearby. They stir silently into action—powering the appliances in the five-bedroom home’s twin kitchens, recharging a $100,000-plus Model X SUV, driving a filter pump for an 18-meter swimming pool sparkling in the shade of a century-old native black bean tree.
