Proving Smart-Grid Savings
Real-world projects show tangible returns.
Much is riding on successful smart-grid deployments. Experiences at several utilities demonstrate the costs and benefits of today’s automation technologies.

The smart grid and its biomorphic destiny.
Smart grid technology is bringing inanimate objects to life. In connecting nodes and equipping the system with distributed intelligence, the network is developing toward an environment that becomes quasi-biological over time. Such an organic system might defy deterministic ideas of planning and control.
Constitutional questions about state-mandated renewable tariffs.
Despite state efforts to follow the European model of state-mandated feed-in tariffs to promote renewable power, these actions won’t pass Constitutional muster. The Supremacy Clause makes a formidable legal barrier.
How to make sustainable performance improvements at any utility.
Sustained performance improvement is often a difficult objective to achieve in a large company. Many such attempts involve various cross-functional initiatives that leave companies with unfinished projects, lower morale and disappointing results. Commonwealth Edison (ComEd) has found that the key to sustained performance improvement is the establishment of a cadre of high-potential managers to address company-wide initiatives full-time.

Why similar U.S and Canadian risk profiles yield varied rate-making results.
Cost of capital is often a contentious issue in utility ratemaking. This is due, in part, to the inexact nature of the tools available to financial analysts and the considerable room for divergent opinions on key inputs to cost-of-capital estimation. Perhaps for this very reason, and to achieve regulatory efficiency, Canadian regulators widely adopted a formulaic approach to setting return on equity (ROE). However, an unusual degree of rancor has evolved north of the border as allowed ROEs in Canada, once at parity, have fallen near 200-basis points below their U.S. peers.
New England grapples with excess capacity and rock-bottom prices.
“Corrosive.” “Seriously flawed.” On the “brink of market failure.”That’s what critics say about New England’s forward capacity market (FCM), whereby ISO New England conducts auctions to solicit offers from project developers to make electric capacity available three years into the future to meet anticipated regional demand.
Forecasting brings wind energy under control.
Advancements in forecasting have improved the reliability of day-ahead and hour-ahead estimates of wind generation. Wind never will behave like a base-load power plant. But as system operators integrate wind forecasts into their planning and market processes, they’re transforming intermittent wind energy into a variable but reliable resource.
