The City of Portland will use streetlights more efficiently to save money and decrease our carbon emissions. A three-step plan will see its first step implemented through this year's budget by reducing the City's streetlights by 25% we will save $225,000 a year.

After assessing the inventory, Public Services Department will eliminate the lights that are not necessary for safety. Over lit areas can cause problems as bright lights cause more shadows, cause people to squint, and force eyes to readjust when leaving the overly lit area. The streetlight reduction will occur along the arterial streets, away from the high-crime areas near the downtown.

The second step will be to convert all of the 1,400 streetlights the City owns to Light Emitting Diodes, which promises energy savings of 50%. The third step will be to gain ownership of the remaining 4,200 lights from CMP and convert those to LED's as well.

Portland to consider lights-out proposal

Streetlight reductions could save up to $225,000 a year and shrink the city's carbon footprint, officials say.

PORTLAND — City officials plan to remove hundreds of streetlights in an effort to reduce the city's carbon footprint and save money.

Officials have yet to decide how many lights to remove, but they say the savings would be considerable.

Removing 10 percent of the light fixtures would save the city an estimated $100,000 a year, Public Services Director Michael Bobinsky told the City Council's Finance Committee last Thursday. Removing 25 percent of the fixtures would save as much as $225,000, he said,

Bobinsky said the most likely streets affected would be the city's arterials and collectors, such as Congress Street, Forest and Washington avenues and parts of Stevens Avenue.

He said the city would not remove lights from high-crime areas, downtown or the Old Port.

Officials also hope to reduce the wattage used by some streetlights; use photocell technology to turn off streetlights when they're not needed; and eventually replace mercury vapor and high-pressure sodium lights with energy-saving light-emitting diode streetlights.

The city spends $1.2 million a year on 7,600 streetlights, the vast majority of which are leased from Central Maine Power.

"It's a lot of money," Bobinsky said in an interview, "and certainly, if there are ways we can reduce that, either with energy conservation or reduced lighting, I think that is what we will try to do."

Bobinsky said the city would remove lights in the middle of blocks rather than at intersections. The city would not remove lights on residential streets, he said.

He said his department would work with traffic engineers and the police department to develop a set of standards for deciding which lights will be removed and which ones will remain in place.

In addition, he said, Ameresco Inc., the Massachusetts company that is doing an energy audit on city-owned buildings, would include the 1,400 lights that the city owns as part of that audit.

Ameresco will identify ways in which investments can save the city money over the long term.

Moreover, Bobinsky said, the city has received $684,700 in federal stimulus funds to be used for energy efficiency, and a portion of the money will be used for buying more-efficient lights.

He said the city is working in cooperation with Central Maine Power, which leases light fixtures to the city based on the wattage of each fixture. If the city buys more energy-efficient lights for the CMP fixtures, he said, CMP would be able to lower the city's lease payments.

The initiative was developed in the council's Energy & Environmental Sustainability Committee, said City Councilor David Marshall, the committee's chair.

He said he believes the public would support the measure if the city can demonstrate that it is taking a thoughtful approach and is being considerate of the impact on neighborhoods.

The savings, he said, could translate into more and better services, such as more police officers.

Councilor Daniel Skolnik, who chairs the council's Public Safety Committee, said he is assured that the public would not be compromised, because Bobinsky is leading the effort.

"I don't think he will do anything reckless to save money," he said. "He is somebody who is a careful thinker and planner, and he knows what he's doing."

The effort to reduce energy consumption is consistent with other city polices, said City Council member John Anton.

"We should have done this a long time ago," he said.

Marshall said the initiative is part of a large national movement in which cities are trying to use lighting more efficiently in order to reduce energy usage and cut down on light pollution.

The public is becoming more aware of the need to reduce light pollution, said Martha Sheils, Maine representative of the International Dark-Sky Association.

Exessive lighting not only wastes money, but it also disorients migratory birds and makes it more difficult for people to see the night sky, she said.

But Sheils, a Portland resident, says the issue of lighting is politically difficult for local officials because people have strong feelings about the topic.

"Some people want more streetlights. Some want none," she said.

John Carroll, a spokesman for Central Maine Power, said the utility will cooperate with the city on the initiative. CMP crews would take down the light fixtures, most of which are on CMP poles. If a fixture is at least 15 years old, there is no fee for removing it.

The City Council will likely discuss the issue next month as part of the budget process.
