Where is the energy storage market heading and where is the disruptive change? (Part 1)

Drivers of future storage markets
Before the dawn of the 20th century, burning wood was the main source of energy. The 20th century witnessed three major fuel transitions from wood to coal, to oil, to gas. The past century also brought us hydro and nuclear power. The use of these fuel sources is not expected to grow in the 21st century; and in fact, some of them, like coal, are expected to become an insignificant part of our energy portfolio. As shown in Figure 1, the flourishing fuels of the 21st century are renewables particularly solar energy that is the most accessible form at the consumer level.

Preparing to meet NERC TPL-001-4? Customer analytics can help

GIFFORDOne of the most intriguing aspects of electric utility customer analytics is the diversity of applications to which they can be applied. Common applications include load research for cost allocation and rate design support, the planning and evaluation of energy efficiency and demand response programs, load forecasting for system planning, and, increasingly, in broader distributed energy resource applications and grid management (e.g., conservation voltage regulation).

Voltage stability modeling is one application that may not be top of mind. In 2013, we kicked off a project sponsored by the U.S. Department of Energy to develop a framework for dynamically representing system load in New England. This work was motivated by NERC standard TPL-001-4 Requirement R2.4, which is to go into effect Jan. 1, 2016. The standard specifies that system peak and off-peak load representations, including the behavior of induction motors and other load components, be developed and updated once in five years for use in annual stability analysis assessments. …READ MORE

Cyber security and real-time electric control center operations

CRAIGLAWRENCEProtection of electronic information and intellectual property, along with a secure digital network, are essential for any modern organization to function safely in today’s electronic digital world. It seems like every day major news media outlets headline a form of cyber-attack on the infrastructure of some industry.

This is especially true for utilities, as they upgrade their systems with intelligent devices to increase operational efficiencies and awareness. With a growing dependency on computer based systems for their operations, cyber technology, and security has emerged as a major concern.

Potential threats make it more critical than ever that organizations protect cyber systems to prevent catastrophic interference with their operations. In particular, real-time monitoring and control network systems are considered critical to the economy, security, and quality of life of a nation. Government agencies and industry organizations are involved in developing standards and best practices to guide the protection of these critical cyber infrastructures. …READ MORE
