Demand side management (DSM) and demand response (DR) programs are one way utilities manage peak energy consumption. DSM and DR are now the law of the land thanks to several pieces of landmark federal legislation. Because demand side changes are typically less expensive and less time consuming than building new power plants, this sector is seeing explosive growth. It’s a critical piece of the Smart Grid, as the resources below reveal.

PJM Interconnection, a regional grid operator, has dropped back to take a second look at a proposed high-voltage transmission project after refiguring its forecast for future energy use. It's looking at when new lines would need to be built, if ever, and other options. |

The Peak Load Management Alliance has published a study on the market potential for water heater demand management that suggests direct load control for water heaters has a lot of potential for reducing peak demand. |

With a high saturation of electric water heating nationwide, direct load control for water heaters has high potential for reducing peak demand, especially to help offset summer peaking driven by electric air conditioning use. One objective of this study released by the Peak Load Management Alliance is to quantify the possible savings from water heater curtailments aimed at reducing summer peak demands. |

The decision whether or not to include customer pricing may be the single largest determinant of how the Smart Grid evolves: A grid with customer pricing will look very different than one that lacks it. What are the implications of each approach? Experts Christopher Russo and Richard Tabors have the answers. |

Until now, much of Smart Grid writing and education has overlooked the consumer. Yet consumer participation is vital to achieving the maximum load reduction from demand response technologies. In this first part of a series on consumers and the Smart Grid, Joe Miller explains what is needed to garner customer support. |

This paper deals with the role of home (and small building) electronic systems and premises equipment in the evolution of the smart grid. It is there, at the end-point or delivery-point of the grid, where the actual use as well as potentially also generation and storage of electricity occurs. |

This is a three-page summary of performed by Freeman, Sullivan consultants. It concerns 10,000 customers who signed up for PG&E's residential SmartRate critical peak pricing tariff in 2008. It compares the load impact estimates with estimates based on the demand models developed for California's Statewide Pricing Pilot (SPP). The demand models estimated from the SPP pilot allow load impact estimates to be made that adjust for the differences between different customers in different geographies. Differences in the two estimates were quite similar in each hour. These findings should provide confidence that load impact estimates based on pricing pilots will in fact be realized if similar tariffs are actually deployed. |

NetApp saw an opportunity to significantly reduce energy consumption at its headquarters, which has 1.2 million square feet of space in 10 buildings. |

A 32-page report that reviews past experiments and pilot projects to evaluate the effect of in-home displays (IHDs) on energy consumption. Concludes that consumers who actively use IHDs reduce consumption by seven percent on average. (Even more if the IHD is combined with a prepayment program. Does not, however, address the issue of consumer fatigue (getting tired of actively monitoring an IHD). |

First in a GE Energy series of slide shows that provides an overview of the benefits and capabilities of a Smart Grid. It details benefits to consumers, utilities and society. |

Distribution in the U.S. has not achieved the same level of communications and control technology found in transmission and generation. These technologies need to be expanded to the end-user level, and a variety of new challenges must be addressed.

Between now and 2025, Ontario must build almost a whole new electricity system. This includes replacing about 80% of its current generating facilities as they retire over time, and expanding the system to meet future growth. That’s why the provincial government directed all local distribution companies to install smart meters in every home and small business in the province by 2010. Smart meters, when teamed with time-of-use pricing, are a key part of building a culture of conservation across the province and achieving signifi cant reductions in peak demand through load shifting. This case study illustrates how Hydro One's intelligent communications infrastructure has laid the foundation for the Smart Grid of the future — a smart network that will integrate energy efficiency, demand response, automation, and distributed generation to enable the grid to operate more efficiently and reliably. |

The benefits of dynamic pricing are well established and increasingly within reach as AMI and other smart grid technologies are deployed.

A five-page white paper from the University of Vermont College of Engineering that proposes an Internet-like, decentralized, bottom-up design for the Smart Grid. The authors view top-down architectures as excessively costly and dangerous to customer privacy. For a general audience. |

A six-page summary of the results of retrofitting two government buildings with demand-response equipment to participate in a PG&E program that provides incentive payments. The project replaced all existing thermostats with wireless thermostats from Cypress Envirosystems. Although this case study was produced by the vendor, it provides an interesting overview of the savings possible by using wireless instead of wired thermostats. |

A two-page flyer from General Electric that explains how the Smart Grid can empower consumers and help them save money. Written to a general audience with several useful examples. |

This Pacific Northwest National Laboratory report articulates nine mechanisms by which the smart grid can reduce energy use and carbon impacts associated with electricity generation and delivery. The quantitative estimates of potential reductions in electricity sector energy and associated CO2 emissions presented are based on a survey of published results and simple analyses. This report does not attempt to justify the cost effectiveness of the smart grid, which to date has been based primarily upon the twin pillars of cost-effective operation and improved reliability. Rather, it attempts to quantify the additional energy and CO2 emission benefits inherent in the smart grid’s potential contribution to the nation’s goal of mitigating climate change by reducing the carbon footprint of the electric power system. |

A 20-page summary of the potential savings available in North America through demand response and energy efficiency programs. Includes a breakdown of all the residential, commercial and industrial measures included in the estimates. Calculates both the "theoretical" and the "achievable" (realistic) electricity savings per year. Written for a technical audience. |

Diagram and tables for smart grid technology solutions for both residential and commercial applications and include solutions from the Home Area Network back to the Utility Infrastructure. |

A 129-page treatise commissioned by Edison Electric Institute and produced by a leading economic consulting firm. Lays out a method to quantify the benefits to utilities and their customers from dynamic pricing (pricing that changes as opposed to the fix-rate programs in place today at most utilities). Time-of-use pricing is an example of dynamic pricing because the cost varies by time of day. Uses the PRISM suite (Pricing Impact Simulation Model). Useful for regulators and utilities contemplating a switch to some form of dynamic pricing. For a technical audience. |

This 45-page table summarizes many North American utility programs for energy efficiency, conservation and demand response. Although the tables provide only a cursory summary, they include links to more information. They are broken down by utility and by state. Useful to any utility or regulator interested in what other utilities have done to date. |

This 139-page report is the most thorough assessment so far of U.S. progress on smart meters and demand response. The top-level findings are that, as of December 2008, 4.7% of all U.S. meters were smart and 8% of all U.S. customers are enrolled in some kind of DR program. Also documents DR developments around the country and reports on remaining regulatory barriers. Concludes with recommendations that FERC continue to make DR a priority and suggests specific actions. Written to an industry audience. |

The city of Boulder, Colorado is one of the first cities in the U.S. to implement a Smart Grid. ABC's news report demonstrates how consumers are able to determine how much energy they are using, at what times, and even where it's coming from. |
