Congratulations to Chugach Electric Association and CIRI for their work on this project!

Chugach Electric Association in June agreed to purchase power from the Fire Island Wind project. When built, the 17.6-megawatt wind farm will be the largest in Alaska. But the Power Purchase Agreement between Chugach and Fire Island Wind LLC needed approval from the Regulatory Commission of Alaska (RCA). On Oct. 10, the RCA made the decision to give that approval.

Under the contract, the price Chugach Electric Association will pay for the wind power will remain constant for the next 25 years, a typical advantage of a renewable energy project that does not rely on fuel with volatile prices. Natural gas prices in Anchorage, in comparison, have more than doubled during the past 10 years, and are expected to continue to rise in the near future.

Fire Island Facts

Fire Island would…
The wind farm would initially include 11 turbines with a total capacity of 17.6 megawatts. Chugach has agreed to purchase up to 48,500 megawatt-hours of power per year from the project, about 4 percent of the utility’s annual 2010 power requirement. The wind power would supplant an estimated 300-500 million cubic feet of natural gas per year, between about 3-5% of Chugach’s current use of about 9 billion cubic feet of gas a year.

Power in 2013
Construction of the turbine sites has already begun. Fire Island Wind LLC, which is a subsidiary of CIRI, plans to install the turbines next summer and expects power to be flowing from the turbines in late 2012.

Wind will cost less over the long term
Under the agreement, Chugach will pay $97 a megawatt-hour for 25 years for wind power. This is more than the $65 per megawatt hour Chugach now pays for natural gas-fired power, but the cost of natural gas will surely go up over the next 25 years while the wind power costs will remain stable. For example, some of the cheapest energy Chugach now purchases is hydroelectricity from the Bradley Lake hydropower plant built in 1991 near Homer. That hydropower cost more than twice that of natural gas-fired power when the plant was built, but is now cheaper because the cost of the hydropower has remained stable.

Wind power is an insurance policy against the inherent uncertainty in the cost of natural gas. Fire Island wind power won’t supply all of our energy needs, but the portion it will supply will be at a fixed stable rate and that will help reduce costs and uncertainty over the long run.

Natural gas supplies for Southcentral Alaska are uncertain
Anchorage utilities are planning to import liquefied natural gas (LNG) as early as 2014 because of shortfalls in supply of local natural gas. In June, the “Long Term Gas Supply Work Group” which includes ENSTAR, Chugach Electric, ML&P and Donlin Creek (a proposed mine project) made a presentation to the RCA, saying they expected a shortfall of up to 2 billion cubic feet of gas in 2014. Right now, the Work Group is not saying where the liquefied natural gas will be purchased, how it will be delivered, or how much it will cost.

Why can’t we just tap the natural gas in Cook Inlet?
There is a lot of natural gas in Cook Inlet. A new USGS report announced a revised estimate of 19 trillion cubic feet of natural gas in Cook Inlet, but that’s gas that technically recoverable, not necessarily economically recoverable. The difference is important. We could harvest snow from Mt. McKinley to make fresh water, but it’s not cost effective.

Alaska is such a relatively small energy user that the cost of developing Cook Inlet gas fields without a large industrial user, like the liquefied natural gas export facility or the Agrium fertilizer plant, is both uncertain and potentially very expensive. A March 2010 study by Petrotechnical Resources of Alaska prepared for Chugach Electric, Municipal Light and Power, and Enstar estimated producers would need to invest between $1.9 to $2.8 billion in natural gas development in Cook Inlet to meet projected natural gas demand from 2010 to 2020.

The Bullet Line?
According to an Alaska Natural Gas Development Authority (ANGDA) report released in July 2011, the estimated cost is $7.5 billion to build a natural gas bullet line from the North Slope to Southcentral Alaska. The line could supply gas by 2020 at an estimated cost just over the current cost of natural gas, according to the report. However, the report says the cost could be quite a bit higher and the project also requires a large industrial customer to purchase half the gas that would be moved through the system because utilities would be only able to use about 250 million cubic feet of gas per day. That large industrial user was not identified in the report.

By Tim Bradner of Alaska Journal of Commerce: Chugach Electric Association’s board has given approval for the electric co-op to purchase wind power from Cook Inlet Region Inc.’s proposed Fire Island wind project, a commitment that will allow the Anchorage-based Alaska Native corporation to proceed with construction.

For the near-term, electricity generated with wind power will be more expensive than Chugach can generate it with natural gas under its current gas supply contracts, but the price of gas in Southcentral Alaska is rising as reserves in existing producing fields are being depleted.

Assuming final approvals of a power sales agreement by both the Chugach and CIRI boards and subsequent approval by the Regulatory Commission of Alaska by mid-September, construction crews will resume on Fire Island in late September or early October, CIRI spokesman Jim Jager said. Read more

A good story by Eric Lidji at the Petroleum News tracing some of the history of the natural gas situation in Cook Inlet: The Kenai gas field started out as an oddball no one quite knew what to do with, but became an essential component of daily life and industry in Southcentral Alaska. And now, at 50, the field is like most people its age: a bit slower, but still moving. The discovery gave the Anchorage region — where two-thirds of the state’s population lives — a crucial tool for survival in the far north: a cheap, nearby source of energy. But abundant natural gas also made Southcentral dependent on the fuel, which is becoming a growing problem as fields like Kenai age and fade away and as natural gas prices locally have risen over the decades since the discovery of the field.

APRN is among the news outlets reporting on efforts by Anchorage to have a plan in place to handle a potential energy crisis this winter in Southcentral Alaska. In each of the past two winters, the Railbelt has come close to having too little pressure in the natural gas pipelines, which could result in a loss of heat and electricity for residents.

This article by Eric Lidji details the potential energy crisis that could result from Southcentral’s dependence on Cook Inlet natural gas for electricity and heat.

Deliverability, the ability of gas line companies to deliver natural gas to consumers, is dwindling, particularly at times of peak demand.  There are several options to fix this problem in the short term, but as gas reserves decline changes in gas supply or gas demand will be necessary.  Lidji explores the current problems facing gas producers, gasline suppliers and consumers, and potential solutions here.

A public forum on Anchorage’s energy future is planned for Saturday afternoon at Begich Middle School. The forum will explore issues such as the declining supply of Cook Inlet natural gas, challenges for local gas and power utilities, and sustainable and renewable energy ideas in Southcentral Alaska.
