DC monitoring raises the bar for solar power plants
As solar generation systems grow in number and size, they will pose new challenges to the electric grid. Integrating solar energy calls for applying sophisticated monitoring and synchronization technology, to allow operators to keep track of operating parameters and ensure as much solar electricity as possible can be integrated into the grid.

Weighing green energy’s costs and benefits.
Policies aimed at promoting one good thing can diminish a better thing, for a net loss to the overall public welfare. Raising prices to promote renewables, for example, makes electricity less affordable and hurts the economy. But artificially low prices can themselves create social ills — by preserving an unsustainable status quo.
Not your father’s feed-in tariff.
The industry has struggled to craft a feed-in-tariff (FiT) structure that works for solar generators and utility customers, with mixed success. But now, the California Public Utility Commission might have found an approach that other states can replicate. CPUC’s FiT mechanism recognizes the value proposition of solar energy, and uses market forces to drive economic improvements, especially for distributed solar projects.
Cap-ex plans raise the stakes for utility mergers.
Investors historically have been skeptical about merger synergies in utility mergers, assuming that regulators will insist that most or all economic benefits flow to customers. However, recent transactions suggest utilities are taking a different approach to valuing synergies that might strengthen the case for mergers — not just for the merging parties, but also for investors and regulators.
Coping with rising profitability, a decade after restructuring.
With a recent flurry of gas pipeline rate investigations at the Federal Energy Regulatory Commission (FERC), many pipeline owners face the prospect of having their profits scrutinized to ensure their rates are just and reasonable. Understanding FERC’s approach will help companies ensure they’re not falling outside the zone of reasonableness.

Out of market means out of luck—even for self-supply.
When the U.S. Federal Energy Regulatory Commission issued its so-called ”MOPR“ decision in April 2011, approving a minimum offer price rule (or bid floor) for PJM RPM capacity market — and then on the very next day did much the same for New England’s FCM capacity market — FERC did more than just prop up prices. Instead, it created a nightmare scenario for utilities that still own their own generation. These utilities, who choose to “self-supply” with their own plants, rather than buy capacity from either the RPM or FCM, adequacy rules, could now be forced to pay twice for capacity — if their own plants are deemed inefficient or uneconomic.
Protecting smart systems against cyber threats.
Smart grid technologies bring a host of cyber security considerations that need to be addressed throughout the T&D domain—and even into the customer’s home. In this exclusive report, Department of Energy authors team up with industry experts to examine how to deal with the changes and challenges of securing the smart grid.
