FERC (Federal Energy Regulatory Commission) "an independent agency that regulates the interstate transmission of electricity, natural gas, and oil. FERC also reviews proposals to build liquefied natural gas (LNG) terminals and interstate natural gas pipelines as well as licensing hydropower projects."

• “While current spot market natural gas prices are in the $4.00/MMBtu range over most of the country, winter futures are significantly higher. Natural gas storage is below average and coal stockpiles are lower than usual. Although new pipeline capacity has been added since last winter, there are still restrictions in New England.”
• “The impact of high winter demand on prices may not be as severe as last year however, as new pipeline capacity in the Northeast should alleviate some bottlenecks within the Marcellus producing region and the New York market area. The additional pipeline capacity could reduce pipeline utilization into New York from peaking at nearly 100% of capacity last winter to around 60% during the coming winter.”
• “This winter natural gas-fired plants will have to make-up for generation lost from the retirement of some non-gas-fired units. With no new pipeline capacity planned until 2016, the region [New England] will need to rely on fuel diversity to meet the region’s energy needs.”
• “That said, the additional capacity planned to increase access to Northeast production does little to alleviate localized New England constraints.”

• “The impact of higher natural gas futures prices is most apparent in New England, where winter electricity futures prices have increased by 84% to $184/MWh. The higher electricity prices reflect the increased cost of natural gas in New England this winter and are consistent with the historical relationship between the pricing of gas and power within the region.”

• “Lessons learned. I almost feel foolish saying this: You know, we need fuel for generators. Oil inventory matters in New England. If I'm going to live off of a gas pipeline system that's constrained, I need coal in the coalyards, and oil in the tanks, if I'm going to be able to reliably supply the system.” –Peter Brandien, ISO New England

• “During the early January event, prices in Boston reached $34/MMBtu at Algonquin Citygates, while during the later January event the price peaked at $73/MMBtu. Most other U.S. gas price hubs traded below $6/MMBtu during these cold spells, with Henry Hub reaching $7.92/MMBtu in February, the highest since Hurricane Ike in September 2008.”
• “Due to the elevated levels of demand most of the regions were operating at the high-cost levels of their supply stacks and in many cases this meant oil units that are not often used because they are not in economic merit order were dispatched. Additionally, some dual-fuel generators were forced to use oil when non-firm transportation of natural gas became unavailable. And on some days, high natural gas prices made oil-fired generation more economic to dispatch than natural gas generation. Head-to-head price competition between oil and gas for power production is not something that has occurred much in recent years.”

• “Outside of the Northeast, basis, the difference between regional price points and the Henry Hub, continues to be low. Growing regional production across the U.S., coupled with plentiful pipeline capacity, has helped to reduce basis nationwide. The highest natural gas prices in the country are in New England. Basis between Algonquin Citygates, a Boston area pricing point, and Henry Hub is up $2.22/MMBtu compared to last year, due to ongoing pipeline congestion in the region. New England experienced occasional natural gas price spikes over $30/MMBtu last winter and prices may spike again this winter as temperatures fall and local pipelines become congested.”
• “For the coming winter, futures prices for natural gas and power are generally comparable to last year’s low prices. The exception is New England, where natural gas futures prices are more than $5.00/MMBtu higher than last winter, pushing futures prices at Algonquin Citygates to nearly $12/MMBtu. Reflecting the close relationship between natural gas and electricity prices, winter electricity peak futures prices in New England increased by 52% from last winter, to $100/MWh.”
