بهترین روش در تامین تجهیزات خدمات الکتریکی پیش فرض : روش مدیریت پرتفوی

As in the past, the vast majority of retail electric customers in the U.S. continue to be served by their default service provider. This trend is likely to continue well into the foreseeable future due to the many barriers that limit customers’ ability to switch to alternative generation companies. How can default service providers achieve low-cost electricity for the masses? We find that several states have adopted strategies for the procurement of electricity that incorporate portfolio management techniques. There is a simple reason for this growing trend: A portfolio management approach is in the ratepayers’ best interest, as it ensures reasonable and stable prices for default electric service. As an added benefit, a portfolio management approach decreases customers’ exposure to a long list of risks, including, but not limited to risks associated with:

As an added benefit, a portfolio management approach decreases customers’ exposure to a long list of risks, including, but not limited to risks associated with: • Fluctuating wholesale market prices • Future environmental regulations • Fuel price and supply fluctuations • Peak cost due to extreme weather • System reliability and security • Market power In addition, there are reasons to believe that such an approach can lead to lower power costs, overall. Below, we explore switching statistics, as well as the portfolio management strategy and its relationship to best practices in default electric service procurement.

In sum, default service providers will continue to service the majority of residential and small C&I customers. These providers have an obligation to provide low-cost, reliable electric service. Portfolio management can help ensure this result. Best practices in portfolio management include a laddered contract approach, with inclusion of longer-term contracts, renewables, and some use of the spot market and/or short-term contracts. 1 “2003 & 2004 Electric Power Customer Migration Data,” Massachusetts Division of Energy Resources (DOER), March 2004, Mass.gov at http://www.mass.gov/doer/pub_info/migrate.htm. 2 While in this article we specifically refer to default service in states where the industry has been restructured, many of the portfolio management concepts described here-in also offer benefits to vertically integrated companies in states where electricity has not been restructured.
