July 15, 2011 - will Maine have a new largest dam?

Friday, July 15, 2011

Since 1954, Maine's largest-capacity hydroelectric dam has been the 85 megawatt Harris Dam on the Kennebec River - but it may soon lose its title to another project on the same river.

Water spills over the last falls on the Cathance River in Topsham, Maine.  These falls powered a sawmill as early as 1716.


Harris Dam may soon lose its title as Maine's largest dam -- but not because a new dam is being built.  Rather, dam owner FPL Energy Maine Hydro LLC -- a subsidiary of NextEra Energy Resources -- has embarked on a program to improve the efficiency of the three turbines at Wyman Dam, the next dam downstream from Harris.

Wyman Dam, currently rated at 83 megawatts capacity, was built in 1930, 24 years before the Harris Dam.  Improvements to two of the three Wyman turbine generators have already occurred, and NextEra now proposes to complete the project.

Between the recent efficiency upgrades and a closer look at older improvements, NextEra now thinks the overall licensed project capacity should increase from 83,700 kW to 88,010 kW, an increase of 4,310 kW.  NextEra has applied to the Federal Energy Regulatory Commission for a license amendment to reflect these upgrades.

Comments on this proposal are due by August 5, 2011.  If approved, Wyman Dam's newly-tallied 88 megawatts of capacity will slip past Harris Dam's 85 MW to become Maine's largest hydroelectric dam.

Stretching slightly beyond energy policy: the Town of Scarborough has finally acquired the parking lot at Higgins Beach. What do you get when you take the Portland area's most consistent surf beach, then ban on-street parking, then charge two arms and a leg for parking in the one private lot in the village? Angry surfers. Higgins was always my favorite break when we lived in Portland, but the parking scene -- especially in summer -- was always a nightmare. If the dirt parking lot was ever built on, it would have eliminated the one place beachgoers could have parked for miles around. The owner of the 1.5 acre lot, plus a 10 acre (presumably unbuildable) strip near the marsh, wanted nearly $1.5 million. Fortunately, a deal has been cut, using $632,145 from the Land for Maine's Future program, a matching amount from the town's bond and $7,270 from fundraising by The Trust for Public Land and the Surfrider Foundation. Thank you.

The Tesoro oil refinery in Anacortes, Washington suffered an explosion and a fire, killing 4 people and leaving 3 more missing.

More on the landslide in Winslow, Maine after the removal of the Fort Halifax dam: Maine Department of Environmental Protection has ordered (former) dam licensee NextEra to study and report on what went wrong. (A bit of pedigree is useful here, since it can be confusing: NextEra Energy Resources is the entity in question, formerly known as Florida Power & Light Energy, or sometimes known as FPLE Maine Hydro LLC.) The landslide threatens the Fort Hill Cemetery, with graves as old as the mid-1700s.

Rail issues: a Pan Am train derailed in downtown Norridgewock Wednesday.

There's a fair amount of hype going around about the weaknesses of the federal EnergyStar appliance rating program.

In Colorado, dominant utility Xcel Energy is replacing 900 MW of coal plants -- 30% of the entire Colorado coal-fueled generation -- with natural gas plants, all because the legislature enacted the Colorado Clean Air – Clean Jobs Act, which caps emissions at 1,100 pounds of carbon dioxide per megawatt-hour. Now it's a race for regulatory approval: by December, utility proposals must be approved by the Colorado Public Utilities Commission, and must be operational by 2017.

Did you know that until this week, there had only been one known tropical cyclone in the South Atlantic Ocean? Now there have been two. Today, the Geostationary Operational Environmental Satellite, GOES-12 identified Tropical Storm 90Q off the coast of Argentina.

In Los Angeles, a good editorial from the LA Times bashing the Department of Water and Power board for endorsing Mayor Villaraigosa's proposed rate hike to fund electric efficiency -- which as reported yesterday, didn't pass.
