  • The national electricity grid yesterday dropped to 2,116megawatts (mw) from the 3,701mw obtained on Monday, daily power report from the Nigerian System Operator (NSO) shows. A difference of 1,585mw was lost but the cause is yet to be ascertained. Following the systematic percentage load allocation to the 11 electricity Distribution companies (Discos), Daily Trust reports that the Discos got ...

    When you run a smart grid magazine, it makes you nervous when your boss says he hates the term 'smart grid.' It makes you knee-knocking nervous, like that cemetery caretaker character in Disney's Haunted Mansion ride.

    Today’s power companies and utilities must deal with unprecedented volatility in power prices, complex transmission networks, and evolving regulatory requirements. Sudden swings in power prices impair forecasts and negatively impact bottom lines. Volatile transmission costs decrease profitability.

    Nearly half of all electricity generated in the world today comes from power plants that use steam turbines built in the days of rotary telephones and manual typewriters, operating at thermal efficiencies of around thirty-percent and thereby discarding seventy percent of the energy in the fuel they consume.

    The way we receive electricity, has not changed to a significant level over last 100 years. The coal (thermal), nuclear or hydro power plants send electricity through transmission lines to substations and to transformers, finer and finer wires and small voltages, until the electricity reaches the electric appliances like lights, televisions, laptops, smartphones etc.

    The term Smart Grid appears frequently now in public press and government strategic documents [1]. A key function in a Smart Grid is the two-way communication between the utility and its customers [2, 3]. In other words, 21st century information technology (IT) that enabled eBay, on-line banking, etc., is now integrated into the nation's electric grid.

    Policymakers across the country are wrestling with the economic impact of aging energy infrastructure. America's energy grid lags behind other developed nations, and according to the U.S. Department of Energy, "power quality issues are estimated to cost American business more than $100 billion on average every year."

    Smart Energy is an industry byword these days. Electricity consumers and producers alike talk about ideas and implementations that Smart Energy has developed as the best ways forward for both energy conservation and energy cost effectiveness. Electrical system developments in Smart grids and Smart cities are key to discussions on Smart Energy.

    The term "Automation (A)" was introduced in the 1970s as a way to describe the use of advanced controls and communication technologies to improve power system performance and reduce operating costs. Its popularity grew, leading to steady, methodical, and systematic advancements that continue to this day.

    The enormous volumes of intermittent generation have made the role of grid balancing ever more crucial, and this has given rise to a new breed of utility, one which points to the future, perhaps, for Europe’s behemoths.

    This issue is dedicated to the ongoing passion of the subjective debates that keep the fires of technology burning away. In these pages, we’ll banter about NASPI synchrophasors, new tech centers, smart grid demo projects, microgrids and even what the single greatest power breakthrough was in the last 100 years. So, don’t sit on the sidelines for this one. Jump right into the fray and swim around in those details. We welcome that. That’s what the #techHEAD issue is all about.

    Innovations in the 20th century drove the fastest and most disruptive transformations in economic history. The automobile devastated the horse-and-buggy industry, railroads consumed large market share from shipping, and airplanes later took passenger and freight business away from railroads. Assembly lines and engines that ran on fossil fuels enabled great leaps forward in manufacturing productivity.
