Sunny Side Up

| From the air, the glowing circle in the middle of the Nevada desert looks more like an image from a mystical dream than a modern form of power generation. But the 110-MW solar farm at Crescent Dunes outside of Las Vegas, NV, is all science and no science fiction, and it also powers 75,000 homes. ... READ MORE

Editor’s Comments: A Digital Orchestra

| Digital pings, percussive thumps, and violin notes emerge as coordinated sounds from a building on Stanford University’s campus. But inside, the Stanford Laptop Orchestra’s tangled cables and video game equipment make it more closely resemble an IT department after a network crash than a conventional music ensemble. ...

Reader Profile: Cyril Toussaint

| While overseeing energy efficiency projects at the nation’s largest public health system may seem like a daunting task to some, for Cyril Toussaint, director of energy management and sustainability at NYC Health + Hospitals, it is both a challenge and opportunity to serve his community, a lifelong role he has relished. While he never set out to get into a career in energy management, the path that led him there—economics and public policy—enabled him to craft a profession in which he has performed so admirably—using his skills in communication, collaboration, strategic analysis, and critical thinking in the service of energy efficiency initiatives—that the Association of Energy Engineers named him Energy Manager of the Year in the northeast region of the US for 2017. ...

Project Profile: Global Village

| Africa is the world’s second-largest and second-most-populous continent. However, it is also the most “electricity-poor” region in the world. Of its estimated population of 1.2 billion people, most live in areas where connecting to a local power grid is impossible due to their extremely remote locations. To bring electricity to these regions, battery-based microgrid systems powered by solar, wind, and hybrid renewable energy sources are successfully providing reliable electricity where grid expansion is not an option. ...

Shared Energy Resources

| There is a familiar backstory in electric power generation that has influenced the industry over the 40 years since the Public Utilities Regulatory Policies Act of 1978 (PURPA) was signed into law. Industry veterans know this story and the younger generation is coming to learn it. Yet the story is evolving, and today, with new technology and business models, a new chapter is being written with the implementation of more efficient, flexible, and intelligent energy resources. ...

Mitigating Electricity Demand

| The slowdown in the growth of electricity consumption and the rapid growth of distributed energy resources currently underway in the electric power sector is causing important utility revenue losses, resulting in challenges to century-old utility business models and current regulatory policies. It’s also providing new opportunities for electricity customers. ... READ MORE

Power Testing

| “Be prepared.” For critical facilities threatened with the possibility of a power cut-off or a community that could face a blackout, the best form of preparation is a backup genset, generator, turbine, or battery. But what about the backup preparation itself? How does an operator know that the backup will be ready when the time comes? Backup power sources tend to sit unused for long periods of time. Therefore, under normal operating conditions, the system operator can never be completely sure that they will be ready when needed. ... READ MORE
