• Boosting Energy Security: Lessons from Post-Hurricane Maria Puerto Rico

    It took nearly a year for the government-run Puerto Rico Electric Power Authority (PREPA), which is the only power company in Puerto Rico, to restore electricity throughout the island. This was the biggest and longest power outage in U.S. history.As scientists suggest that weather will probably become more extreme and weather-related natural disasters are likely to intensify in the coming decades,we can learn some valuable lessons from what Puerto Rico has gone through in the wake of Hurricane Maria.

  • Risks Grow as Countries Share Electricity Across Borders

    Increasing interconnection of electricity systems both within and between countries has much promise to help support clean energy power systems of the future. If the sun isn’t shining or wind isn’t blowing in one place, an electricity grid with high voltage transmission lines can move electricity to where it is needed. This shared infrastructure and increased trade can possibly serve as a basis for peace between neighbors in conflict, but it may also serve as a tool of coercion if the electricity can be cut off by one party.

  • Optimizing use of future wave electricity generators during disaster

    When hurricanes strike, loss of electricity ranks as one of the top concerns for relief workers. Blackouts lasting a week or more can hamper recovery efforts, shutter hospitals, threaten public health and disrupt transportation. The months-long effort to restore power to Puerto Rico following the 2017 hurricane season has led to renewed interest in finding innovative ways to get affected power grids back online. Researchers look to develop a strategy for how floating devices that harness the energy of the oceans’ waves might be able to provide this much needed aid.

  • Vulnerable grid: Argentina's nationwide blackout

    Blackouts which affect an entire country are incredibly rare – but one just hit Argentina on Sunday. Since April, an electricity transmission connection between two power plants in Colonia Elia and Nueva Campana has been out of service. Even with that connection not in service, Argentina’s electrical grid was supposed to withstand another connection being severed from the grid. But when a second connection went offline on Sunday, the entire national grid was put out of action.

  • Electricity grid cybersecurity will be expensive – who will pay, and how much?

    Russia, China, North Korea and Iran are capable of hacking into the computers that control the U.S. electricity grid. Protecting the grid from hacking would cost tens of billions of dollars. The electricity customers will likely foot most of the bill.

  • Signals from distant space could help secure electric substations

    Side channel signals and bolts of lightning from distant storms could one day help prevent hackers from sabotaging electric power substations and other critical infrastructure.

  • Predicting impacts of extreme events on grids

    A new, free, open-source software reliably predicts how damage from hurricanes, ice storms, earthquakes, and other extreme events will restrict power delivery from utility grids. The Severe Contingency Solver for Electric Power Transmission is the only software available—commercially or open-source—that reliably supports analysis of extreme events that cause widespread damage.

  • AI automatically detects disturbances in power supply grids

    The grid is changing as the big, centralized providers of the past are replaced by smaller, distributed suppliers. Keeping such complex networks running stable requires high-resolution sensor technology – AI provides a way to make accurate predictions and automatically detect any disturbances or anomalies in real time.

  • Modernize the energy grid software

    The grid is an intricate, highly complex system. One that has gotten even more complex with the increasing use of renewable energy resources like wind and solar. At some point, something will go wrong. A line will get cut. A generator will fail. There might be a hurricane or a cyberattack. How do you quickly correct for that failure to avoid a cascading blackout?

  • Next-generation grid security tech

    Researchers will demonstrate the effectiveness of metro-scale quantum key distribution (QKD) as a means of secure communication for the nation’s electricity suppliers. This initial milestone is part of the team’s three-year project focused on next-generation grid security.

  • Transformative grid technology

    Avista and the Department of Energy’s Pacific Northwest National Laboratory announced they will enter an agreement to strengthen and expand their partnership at the frontiers of grid modernization. The scope of the new agreement includes collaboration on new battery and thermal storage technologies, and the development and testing of transactive building controls for increased grid reliability and resiliency.

  • How Russia hacked U.S. power grid

    In an aptly titled investigative report — “America’s Electric Grid Has a Vulnerable Back Door—and Russia Walked Through It” — the Wall Street Journal has used “documents, computer records and interviews” to reconstruct exactly how Russian hackers accessed the U.S. electric grid in the spring of 2016, an attack that continued through 2017 and possibly 2018.

  • Friendly electromagnetic pulse improves survival for electronics

    An electromagnetic pulse, or EMP, emitted by a nuclear weapon exploded high above the United States could disable the electronic circuits of many devices vital to military defense and modern living. These could include complicated weapon systems as well as phones, laptops, credit cards and car computers. Also, in trouble might be home appliances, gas station pumps and bank accounts. Military equipment – and some civilian equipment, too — are designed to be immune to various levels of EMP, and the validity of these designs has been tested and improved by a “friendly” EMP generator installed in a recently renovated facility at Sandia National Laboratories.

  • Predicting the impact of hackers, earthquakes -- and squirrels -- on the power grid

    What would it take for an entire American city to lose power? What circumstances and failures in the electrical grid’s infrastructure would lead to a dramatic, long-term blackout? And what weak points could utility companies invest in to help prevent a catastrophic shutdown?

  • Using game theory to quantify threats of cyberattacks on power grid

    Threat levels for cyberattacks on the power grid are usually labeled high, medium or low, but engineers say this is not good enough: Such judgements are too qualitative and too subjective. Could engineers incorporate scientific methods? Computer algorithms? And given that there are attackers and defenders – just like in a soccer match – could game theory be applied to help with risk assessment, attack-defense modeling and “what-if” contingency analysis that could help mitigate any attacks?
