Commercial fishing and solar energy

Commercial fishing businesses tend to consume significant amounts of energy, but may be able to offset their energy expenses by turning to solar panels and other distributed electric generation.

According to the National Marine Fisheries Service, the U.S. commercial fishing sector landed $5.3 billion in seafood last year.  Alaska led the nation in total catch value in 2011, landing $1.9 billion in fish and shellfish.  Massachusetts came in second at $570 million, with Maine coming in third at $426 million.

Catching this seafood comes at a price.  Diesel and other marine fuels account for a significant fraction of commercial fishermen's expenses.  Onshore, electricity powers stationary facilities like freezers, refrigerators and pumps for holding tanks, with seafood processing operations consuming even more power.

The location of many commercial fishing businesses -- typically located on the coast, often on a pier or wharf exposed to the sun and wind -- may create an opportunity for fishermen to offset their energy costs by producing their own electricity.  One Maine lobsterman recently added a 10-kilowatt solar array to his wharf in Harpswell. Funded in part by an $11,750 grant through the U.S. Department of Agriculture's Rural Energy for America Program, last month Potts Harbor Lobster added 44 solar panels to two roofs on the Reversing Falls Lobster wharf in South Harpswell.

In addition to USDA REAP grants, additional incentives are available that may shorten the payback period for distributed generation projects at commercial fishing facilities.  For example, Maine's net energy billing law allows consumers to use solar or other distributed generation to effectively spin their electricity meters backwards.  Consumers in almost every state can use similar net metering programs to sell excess power back to the grid, offsetting their electricity bill.  Other states, like Massachusetts and New Jersey, allow consumers to produce and sell solar renewable energy credits (sometimes called SRECs) from grid-connected solar photovoltaic panels.  These SREC sales can create a significant revenue stream for people and businesses who develop qualified renewable power projects.

Not every site may be well-suited for distributed generation projects.  Given relatively high capital costs for many small renewable power projects, payback periods may be too long for some businesses to make the investment.  However, as the cost of electric transmission increases across the country, the traditionally self-reliant fishing industry may increasingly turn to solar energy and other distributed generation technologies.

September 1, 2010 - vehicle energy efficiency; federal renewable power?

A stone wall, forgotten in the woods in Bath, Maine.  Most stone walls in New England were built between 1750 and 1850; in 1940, a United States government survey estimated that there were more than 250,000 miles of stone walls in New England -- almost all built by manual labor and power from draft animals, during a time of lower energy intensity.

 
From the vehicle energy efficiency department: the U.S. Environmental Protection Agency and Department of Transportation are jointly revising vehicle window stickers for the 2012 model year. This Wired article describes one option they are considering: assigning new vehicles letter grades for fuel efficiency.  (Examples from the article: Nissan Leaf: A+.  Plug-in Toyota Prius: A.  Toyota Camry: B-.)  Electric vehicles appear more likely to play a larger role in transportation in years to come.

Some may recall the day in 1979 when President Jimmy Carter installed solar panels on the roof of the White House.  They didn't stay there long; President Reagan removed them in 1986.  By 1990, they were donated to Unity College in Maine.  Now, Bill McKibben and others are taking the solar panels to Washington in an effort to convince President Obama to install solar or other renewable generation at his house -- not to mention the federal government's role as the nation's largest energy consumer.

I watched this week's deliberations of the Maine PUC as the Commissioners conditionally approved Central Maine Power's plan to upgrade a section of its 34.5 kV transmission line to 115 kV.  The reason?  To let power from Record Hill Wind LLC's project reach the grid.  The Commission required the wind developer to make a three-month prepayment to CMP of all construction costs, and report to the Commission quarterly as the project moves forward.

Island issues: I've written before about the difficulties of ensuring a water supply on island communities -- both potable water for drinking and any old water for firefighting.  Monhegan, for example, has a culture that is purposely very alert to fire danger.  Today's news has an example of why: fire destroyed a home on Pole Island in Quahog Bay in Harpswell -- despite valiant efforts by firefighters, neighbors and volunteers.
