What's happening at the substation? Condition monitoring boosts savings and reliability

Most utilities employ a time-based approach to maintaining and replacing electrical substation assets. However, sometimes these schedules are overtaken by events. Substation equipment commonly endures a surprising amount of wear and tear from network conditions (such as overloading) and harsh environmental conditions -- both cumulative and sudden. It's not always possible to predict when substation equipment might fail. But when it does, this can lead to unplanned outages, damage to other equip ...

Rethinking Utility Tariffs for Distributed Energy Resources

As distributed energy resources (DER) continue to proliferate, and at an accelerating pace, we are seeing regulators and utilities adopting new concepts in designing rates – for example in Hawaii and in Europe. A key element of this is a new focus on the rates associated with the distribution of electricity, the wires portion of the business. These rates recover the cost of building and maintaining the wires – plus all the associated equipment, such as substations, devices connected to stabiliz ...

Will Data Science Discipline Help Utilities Analytics Practices?

The answer to the above question is yes. At least all participants of Siemens Twitter Chat on July 22, 2015 did concur that data science is an important discipline for utilities to gain deeper insights into the data.  You can follow the conversation at #utilichat on Twitter. It was apparent from the Twitter Chat (#utilichat) that we have more questions about solving many challenges for utilities. Utilities do collect a lot of data and volume has increased in the past few years. Zpryme survey co ...

California Utilities Propose Next Generation Net Energy Metering Rates

Last week, utilities and interested parties filed rate proposals in the proceeding to determine the next generation of tariffs for customers with on-site generation, such as rooftop solar. Such customers in the U.S. have typically used a Net Energy Metering tariff (NEM), first adopted in 1980 in Idaho. Under NEM, customers’ meters keep track of only the net energy consumed in a month; i.e., the total consumed minus the total produced by the customer’s rooftop solar system. So a customer’s bill c ...

Utilities of the Future: British Gas Refocusing on Customers

Much has been said about the "utility of the future." British Gas is joining other European majors such as E.ON and RWE and not just talking the talk but walking the walk.In its earnings announcement last week, Centrica (British Gas's parent) said it was cutting back investment in its oil and gas division and focusing on being a customer-facing business. This was the headline finding from its corporate strategic review.Like E.ON and RWE, British Gas is turning toward what it calls its ...

Empowered Consumers Like their Utility

J.D. Power’s new customer satisfaction survey found consumers want to control their energy use and, actually, communicate with their utility. They also like having choices.Overall customer satisfaction rose for the third year in a row, with communications and price satisfaction the drivers. Today's customers not only want more communication, but they want it to empower them. Control: consumers want more control over their energy consumption and production. Almost 30% of customers are considerin ...

New York Approves Major New Demand Response Programs for This Summer

Last week, in its Reforming the Energy Vision (REV) proceeding, and based on the success of a similar program at Consolidated Edison of New York, the New York Public Service Commission approved new demand response programs for the other four regulated New York’s utilities: Central Hudson Electric & Gas, New York State Electric and Gas, Niagara Mohawk Power, and Rochester Gas and Electric. The programs are in line with the state’s REV vision, a process for transitioning the electric system t ...

Exploring Merits of the Transactive Energy Model

I recently attended a workshop hosted by GridWise Architecture Council (GWAC) on transactive energy. The participants discussed developments of Transactive Energy in North America. There was discussion on how Transactive Energy concept is evolving and who can benefit from it. According to GWAC: “The term “transactive energy” is used here to refer to techniques for managing the generation, consumption or flow of electric power within an electric power system through the use of economic or market ...

Weinhold’s Power Lines: Brains and Brawn - The Electronics Revolution and the Energy System

What is power? In human interactions, the term often refers to physical strength, but we also speak of “the power of information” as a way of shaping and directing the course of events. Power is the ability to influence the world in both material and immaterial ways – through intelligence and muscles, through brains and brawn. The same is true for the way in which electronics has reshaped the energy system. It was the invention of the transistor and its first commercial usage in the 1950s that ...
