When microgrids are optimized in a smart grid, they’ll usher in a new era of utility resilience and flexibility. Get ready for dynamic microgrids.
Threat From Behind the Meter
The case for utilities to compete directly with distributed resources.
do so through unregulated affiliates, either newly formed entities devoted to behind-the-meter energy markets or existing merchant energy businesses.
Under this model, policy makers could prohibit cross-subsidization of unregulated businesses through familiar regulatory protections such as ring fencing and prohibitions on information or employee sharing with unregulated affiliates. With such protections in place, unregulated affiliates may develop, own, control and operate non-traditional behind-the-meter energy supply projects and services, and they also might elect to participate in competitive wholesale markets. Meanwhile, ring-fenced regulated utilities would retain the obligation to ensure access to the transmission and distribution system for all energy service providers on a non-discriminatory basis. An additional benefit is that by separating the increasingly risky wholesale and retail competitive energy services businesses from the traditional regulated utility operations, investors gain greater certainty of utility capital investment cost recovery. The resultant enhanced credit profile could lower a utility’s cost of capital and ultimately reduce the cost of regulated utility investments.
Energy firms that own both regulated utilities and unregulated merchant businesses appear to be recognizing the benefits of structural separation for mitigating the risk posed by behind-the-meter energy. Several are making investments and developing competitive behind-the-meter energy services through unregulated business units ( e.g., Dominion) and others appear to be targeting behind-the-meter energy business as a strategic focus ( e.g., Edison International). 24 These and other examples suggest that structural separation of regulated utilities from competitive merchant energy service businesses could again provide a useful strategy for addressing the emerging threat to the sustainability of the traditional utility and regulatory model.
And that’s fortunate, because there’s no time to waste.

It is actually a threat to the structure of any business that depends on selling into the wholesale grid – including the wind and other renewable industries that cannot sell behind, or without, the meter.” See: “NRG CEO: Distributed generation a ‘mortal threat’ to utilities,” SNL Energy , March 22, 2013.
