Are merchant power assets overpriced?
By some measures, merchant power assets look like a bargain, selling for well below their replacement cost. But whether low prices signal a buying opportunity or a value trap depends on the outlook for electricity demand growth—not just in the long term, but also in the fairly immediate future.
The Federal Energy Regulatory Commission (FERC) in mid-October granted a trimmed-down set of rate incentives for the proposed $1.6 billion RITELine transmission line project.

Preparing the grid for large-scale renewables.
With large solar arrays and wind farms being proposed to connect to transmission and sub-transmission systems, are utility companies sufficiently prepared to handle the challenge of integrating these large intermittent resources? The industry now must decide whether transmission reliability factors — most notably dynamic voltage support and system frequency management — need to be resolved by renewable generators, or whether they should become a cost of doing business for transmission providers and reliability coordinators.
Utility-scale projects suffer growing pains.
Anyone who’s been watching the solar power industry for more than a few years can’t help but be impressed by the recent explosion of large-scale projects. It seems akin to the rapid scale-up of wind in the late 1990s and early 2000s—when megawatt-scale turbines became standard-issue, and the definition of a “large” wind farm changed from a capacity of 20 MW to something more like 200 MW.
Raising the stakes in RTO markets.
Generators and demand-response providers are reaping rewards in forward capacity auctions, causing suppliers to go shopping for the most lucrative markets. Now the Midwest ISO is trying to catch up, by proposing its own auction for years-ahead resource bids. But does RTO shopping serve the interests of customers, who are legally entitled to rates that are just and reasonable? Why are some state policy makers advocating a return to old-school RFPs for long-term contracts?
