    A few things have become abundantly clear in light of the August 14 blackout that crippled the Northeast. The first is that the nation's electrical transmission and distribution system is badly in need of an upgrade.

    The second is that that upgrade won’t happen anytime soon.

    Congress is at odds over whether to include system reliability issues in an already-controversial and long delayed national energy bill. And however the issue is addressed, there is little political consensus on the means to a solution, especially when Energy Secretary Spencer Abraham proclaims that the costs of system upgrades, estimated at roughly $56 billion, will be borne principally by ratepayers.

    Add opposition to the Federal Energy Regulatory Commission’s proposals to create regional energy authorities to regulate energy transmission across state lines and oversee system upgrades, as well the local opposition likely to arise when and if sites are designated for the construction of massive new high-voltage transmission lines, and it becomes clear that grid improvements are a long way from reality.

    There are, however, solutions that can meet short-term demand response needs while also accruing long-term energy savings, having both immediate and lasting impacts on our nation’s energy system. Energy efficiency measures provide the quickest, cleanest and cheapest way to help ensure that the regional and interconnected electric grids are not again overwhelmed.

    For the past 15 years New England ratepayer-funded energy efficiency programs have yielded cost-effective peak demand reductions and energy savings that nearly equal the capacity and annual output of the 1,100 megawatt Seabrook, N.H. nuclear power plant. In doing so, these programs have saved consumers over $250 million in avoided energy bills, and helped to relieve the strain on a regional electric grid that includes the most congested transmission area in the country, Southwest Connecticut. A broader commitment to such energy efficiency programs and policies can extend these benefits and provide badly needed transmission and distribution capacity until such time as the daunting task of upgrading our national T&D system can be realized.

    Ratepayer funded energy efficiency programs, administered in a number of different formats throughout the Northeast, help introduce to consumers energy efficient products – like efficient lighting, appliances or equipment – as well as best practices – such as resource efficient commercial building operations and maintenance. During the most recent budget difficulties, however, these funds have come under attack as a quick-fix budget solution. To take these ratepayer funds and use them for anything other than their intended energy purposes is wrong under any circumstances, but potentially calamitous given the fragility of our energy grid. If anything, states need to increase their commitments to energy efficiency programs to expand on the demand reductions they bring.

    To complement these programs, both federal and state policymakers also need to act on energy efficiency product standards. Legislation being considered in several Northeast states, including Maryland, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, Massachusetts, Maine and New Hampshire, would enact standards for 10 common residential or commercial products, ranging from ceiling fans to traffic signals. By implementing these standards, the Northeast would realize an estimated 9,335 gigawatt hours in energy savings by 2010, which is the equivalent to the energy required to power over 1.5 million households. Those same standards would also reduce peak energy demand by over 2,100 megawatts by 2010, which is the equivalent of seven power plants.

    The federal government also needs to recommit to efficiency standards on two fronts. First, legislation in the current energy bill would for the first time in over a decade enact a new set of efficiency standards for a range of products. These provisions need to be considered as vital pieces to the complex set of solutions to our transmission and distribution capacity constraints.

    Second, the Department of Energy needs to act on the standards mandates they have been given. In 1992, the DOE issued an advanced notice of a proposed rulemaking on a standard for residential furnaces and boilers, but still hasn’t set that standard over a decade later. The hard work of gaining legislative approval for these standards has been done; it’s now incumbent on the administration to order DOE to act on those mandates.

    Finally, regional power system planners and state regulatory commissions should explicitly include in power system planning and development the potential of energy efficiency to meet future system needs and relieve grid constraints. The Northwest Power Planning Council – the only regional planning power planning body in the country that considers the potential of energy efficiency – found that over the past 20 years energy efficiency programs and polices met 25 percent of system growth in the Pacific Northwest, and can provide at least 12 percent of future projected growth in that region for the next 20 years.

    The problems with our electricity system didn’t develop overnight, and they won’t be solved overnight. But until they are, energy efficiency can and should play a vital role in addressing both the short- and long-term issues of system reliability. To ignore this readily available solution is to risk the lights going out … again.

    Dear Susan, I don't know why you need "energy bill" to improve the T&D system. Secondly your projections of saving around 2% to 3% of energy in 7 years is too meagre or almost no improvement. Even if all organisation like yours are shut down, 3% improve will be there automatically. YOU DON'T NEED BILLS TO IMPROVE SYSTEM. As per my estimation USA electricity system can save $1000 bn in 10 years through innovative projects. --Ravinder Singh, ravindersinghy77@yahoo.com

    The way I see it, there are 2 solutions to the problem. One is to upgrade the high voltage grid, which requires a significant investment by the Transmission companies, and with a limited rate of return on this investment, it is not likely, unless mandated by the government. The alternative is localized generation, especially from alternative sources. Solar and wind energy could provide significant reductions in the high voltage transmission capacity required. However, there is a down side to this, especially from the perspective of the distribution companies. If the incentives were strong enough such that most homeowners decided to install solar panels on their roof tops and wind generators in their back yards, it seems that distribution companies would lose their "raison d'etre". How would they recover thier infrastructure costs for those consumers that are still grid connected without having to charge them a disproportionate amount? Hmmmm.....Quite honestly, I would love to be off grid!

    In order to develop a comprehensive solution a broad view must be taken. In fact, it will be necessary to step back and review the current energy policy and regulatory structure which, de facto, discourage strategies like distributed generation. I am not speaking of base load mini-plants (although fuel cells may have a part to play in the future), which are far more expensive to operate than a conventional coal or nuclear plant. I am referring to conventional fueled .5 to 1.0 MW units that are, or can be, installed in many of the millions of small industrial and commercial buildings that populate our most intensively populated areas of the country where the capacity is needed most. The purpose of these units would not be to compete with base load capacity, but to provide relief during peak periods by DISPLACING native building loads. We demonstrate regularly how these units can show a payback of under 3 years, even in the current regulatory and economic environment.

    Various energy strategy descriptives have come into vogue in recent years, such as cogeneration, renewable energy, sustainable energy, and distributed generation to name a few. It may be time for a new concept such as Diversified Capacity. There is little diversification on the base load/primary supply level such as, coal, nuclear, and hydro power which make up the largest percentage of the generating capacity supplying the grid. This is because currently, these are simply the most economical technologies for producing bulk power. At $0.01 to $0.02 per kilowatt-hour, other fuels or technologies cannot compete with these with respect to sheer volume of energy which can be produced for general consumption. There is little on the horizon to further diversify our primary power production in the short term, except for possibly fusion, which may deserve as much attention and research as fuel cell technology.

    Natural gas and oil make up almost all of the peaking capacity. These plants provide incremental power mostly during daytimes when hours, and primarily during summer months to satisfy large air conditioning loads. Most of the time these plants are in stand-by mode, unless there is a need for supplementary or emergency power. It is here that opportunity exists for diversified capacity since small natural gas and oil fired generators can be installed by the end user to offset individual short term peak loads, instead of relying on a distant plant and a crowded transmission system. This would require no additional research or development since the technology is already in use. In fact, there are millions of stand-by generators that are already installed across the country, some of which might only require some upgrade of generating equipment and switchgear in order to function as displacement capacity. Some states have more than 2,000 megawatts of non-utility generation that currently can’t be connected to the grid - the equivalent to a large nuclear power plant – in each of the 50 states! What is needed to harness the existing and new potential capacity is simply regulatory modification and economic incentives, which should be a part of the upcoming revisions in energy policy.

    Currently, generation providers have no incentive to promote the installation of small generating units (i.e. industrial, institutional, commercial) into the system. LDC's, along with their affiliates, do not promote the expansion of interruptible tariffs to provide displacement capacity during high peak periods, PUC's do not require appropriate economic incentives for interruptible tariffs, and there are no federal incentives. In addition, retail electric providers are not required to offer any interruptible rate programs that could provide additional displacement capacity. Finally, there are no code requirements or economic incentives for displacement capacity (stand-by/displacement generators) to be installed in new construction which would reduce the growth of capacity requirements, therefore transmission requirements, for peak periods.

    Also, one issue that consistently seems to be given short shrift in discussions about generation and transmission is Demand Side Management. Anyone in the demand side industry knows that energy consumption can be reduced by as much as 40% - even more - with the technology that grew largely out of the Energy Policy Act of 1992. In addition, electric demand can be reduced by 30-40% (100% if displacement strategies are included). All of this can be done (and IS done every day) with off-the-shelf technology such as upgrading lighting systems, installing variable speed drives on electric motors, and integrating building operations with energy automation systems, which now can control energy consumption and demand in real time. Upgrading lighting alone can reduce electric demand in a commercial building by 20-25%. Reducing the building’s electric demand allows reduction of the displacement generation capacit

    Conclusion to the comment above:

    Generation and transmission problems must be addressed, but Diversified Capacity and Demand Side Management must be part of the short and long term solution - and should be the first place to start.
