The MAPP line, PEPCO’s Mid-Atlantic Power Pathway transmission line project through Maryland and Delaware, is in the news again. But why???  Where the line is not needed, and it’s withdrawn by PJM and PEPCO, why is this being accepted?  Why is this regarded as a “win?”

Remember that they pulled the project?

PEPCO letter 1.8.09 to suspend MAPP, includes 1.8.09 letter from PJM’s Herling

And before that, the part from Indian River to Salem was eliminated?

MAPP – PEPCO-PJM Press Release May 19, 2009

The May, 2009, Press Release says:

According to Gausman, PJM has also reviewed the need for the section of the line that would run from Delmarva Power’s Indian River substation near Millsboro, Del., to Salem, N.J., and has decided to move this portion of the line into its “continuing study” category. This means that the reconfigured MAPP line will now extend approximately 150 miles from northern Virginia, across southern Maryland and the Chesapeake Bay, and terminate at Indian River. The change would likely reduce the total project cost from $1.4 billion to $1.2 billion.

And then there’s the report that shows there’s no need, that demand is downdowndown, that “congestion” is downdowndown, that price of electricity is downdowndown, that demonstrates that the market concept that they’re all drooling over will have them aspirating their aspirations:

So then why did they send out a press release last week:

PEPCO May 5, 2010 Press Release – MAPP Transmission Line

…which every Peninsula news outlet gave pretty much verbatim coverage?

And then there’s the PJM RTEP 2009, released February 26, 2010.

So here’s how their press release looks after the papers get it:

Delaware utilities: Plan takes power line under Choptank


Proposed route would lead to little disruption in Del.

By AARON NATHANS • The News Journal • May 8, 2010

Delmarva Power’s planned high-voltage power line would be submerged below the Choptank River through Dorchester County, Md., the utility announced this week.

The Mid-Atlantic Power Pathway would run from Virginia to Maryland, across the Chesapeake Bay and end at the Indian River Power Plant in Millsboro.

It is being planned by Pepco Holdings Inc., parent company of Delmarva.

The company reports it has been successful in acquiring 90 percent or more of the rights of way needed to build the line through Dorchester County.

This portion of the line would run below the Choptank River, making landfall east of Cambridge, Md. It would continue underground briefly before moving above ground northeast of U.S. 50. It would cross the Nanticoke River near Vienna, Md.

In Delaware, the power line would be built on existing rights of way, approaching from Mardela Springs, Md., moving toward Delmar, and finishing in Millsboro.

Delmarva would not need to widen existing rights of way or clear any vegetation in Delaware, spokesman Matt Likovich said. The existing poles along this route would be replaced to support the more powerful lines, he said.

The portion of the line that runs through Maryland requires approval from federal and state agencies, including the Maryland Public Service Commission. Delaware’s PSC has no such oversight authority.

“We’ve spent a great deal of time listening to the citizens of Dorchester County,” said Bob Jubic, project manager. “With input from landowners, residents, environmental groups and government officials, we believe that the Choptank Route is the best choice as it minimizes the impact on the environment, agriculture and culturally significant areas in the county.”

Pepco Holdings has already announced the route for the MAPP project on the other side of Chesapeake Bay. About 20 of the 72 miles there would need to have new structures installed, and would also need new structures to cross the Potomac and Patuxent rivers.

PSC approval is unlikely to come until PJM Interconnection, the regional power grid manager, decides next month whether new power lines will be needed to ensure electric reliability in the region. Delmarva officials say they are not waiting for that green light to plan for the line, which they hope to have in service in June 2014.

Delaware PSC Chairwoman Arnetta McRae wrote a letter to PJM last month expressing the commission’s opinion that the project should go ahead on schedule to relieve reliability and cost concerns, and to provide a future pathway for offshore wind power to flow through the area.

Maps of the route through Dorchester County will be on public display at the Holiday Inn Express in Cambridge, Md., on Wednesday from 4 to 8 p.m. during an information session with the company. For more information, call the MAPP office at (410) 221-6207 or visit www.powerpathway.com.

Now read the other “articles” and tell me if there’s an echo in the room:

Underwater power line route suggested
Proposal under Chesapeake avoids refuge

But the day before it was better, with some original quotes:

Delmarva Power proposes Choptank route for MAPP project

(with NO byline)

Sussex County has held off on taking a formal stand on Delmarva Power’s Mid-Atlantic Power Pathway, or MAPP, but Delmarva is pushing,  so now’s the time to call them with a simple message:

No, don’t encourage and facilitate coal!

Say NO! to Delmarva Power’s Mid-Atlantic Power Path transmission proposal!

Delmarva Power is going around drumming up support for its Mid-Atlantic Power Pathway, or MAPP.  They approached Sussex County to support the line (what do we know about that?  Not much.  Perhaps a FOIA to see what they’ve been doing is in order?) and because there’s a zoning matter before the County, they held off..

Delaware Electric Coop would like to use the MAPP line to bring in electricity from a new Old Dominion coal plant in Virginia.  Oh… great idea… I’ve posted about this before:

Building a coal plant is a really bad idea, and building transmission for coal is a really bad idea plus… two wrongs do not make a right.

Call all the County Council, thank them for putting on the brakes, and let them know what you think about Delmarva Power’s transmission for coal:

Sussex County council delays support of transmission line

Pathway could pump $260 million in county’s economy

By Ron MacArthur

More than a dozen elected bodies and agencies are throwing support behind the Mid-Atlantic Power Pathway, but Sussex County Council will not join that list – at least not right away.

The 150- to 170-mile high-voltage transmission project, scheduled to be completed in June 2014 at a cost of $1.2 billion, would include 35 miles of lines from Vienna, on Route 50 in Maryland, to the Indian River power plant near Millsboro.

Delmarva Power and Pepco Holdings Inc. were seeking council’s support of the Mid-Atlantic Power Pathway (MAPP) project during the county’s Tuesday, Oct. 27 meeting. But council is handcuffed because a zoning application is pending before county officials. A converter station will need to be built near Millsboro.

“Would we be pre-judging this zoning application with support of this?” Council President Vance Phillips asked county attorney Everett Moore.

Moore responded with an emphatic yes.

Phillips told Delmarva Power representatives the council would discuss the matter with its attorney. “We will see if we can come up with some sort of endorsement broad enough not to get ourselves in trouble,” he said.

“This is one of the most important projects ever undertaken by Delmarva Power and Pepco,” said Jim Smith, Delmarva Power senior public affairs manager.

Demand exceeds generation

Jerry Elliott, a Delmarva Power retiree with 35 years’ experience, has come out of retirement to help with the project. In a presentation to council, he said the Delmarva Peninsula depends on imported power, with demand exceeding generation by 500 megawatts during peak periods. Officials say demand will increase by 20 percent during peak periods over the next 10 years.

Power is transmitted from north to south from a single connection point in New Castle County. As a result, he said, more brownouts and blackouts are projected in the future for residents in southern Delaware.

“Even with the economic downturn, without MAPP there is insufficient transmission and power generation capacity to meet demand by 2014,” Elliott said. “The peninsula is isolated from power sources on the western shore and cannot import enough power in the event of an emergency.” He said the single point of access to the grid also results in higher costs for electricity on the peninsula when lower-cost power is available in the region. “MAPP will lower the cost of power by relieving transmission-line congestion,” he said.

Because no new transmission lines have been built on the peninsula in the past 25 years and the area is susceptible to brownouts and blackouts, the area has been designated a Department of Energy National Interest Electric Transmission Corridor.

Matt Likovich, Delmarva Power community and communications coordinator, said the 51 million customers in the project area will be charged 30 cents a month, a charge that will be offset by a savings in congestion charges.

“The cost of electricity during periods of congestion is much higher than at other times. The MAPP project will help relieve transmission-line congestion on the Delmarva Peninsula, resulting in cost savings to customers,” Likovich said.

He said anticipated savings are about 60 cents per month in charges related to congestion.

Line will go under the bay

Elliott said 500-kilovolt and 640-kilovolt lines will tie into power plants starting in southern Maryland at Possum Point to Calvert Cliffs with 11 miles taken under the Chesapeake Bay through Dorchester County to a plant in Vienna and then to the Indian River plant.

Almost all of the project will take place on existing rights of way, except in Dorchester County. “Dorchester County does not support this yet,” Elliott said. That is why the exact mileage of the project is not yet known. The final figure depends on what officials in that county decide.

While most of the new lines will be built in place of existing lines, the Dorchester County portion will add new lines to the landscape, which county officials say would harm tourism and agriculture. Dorchester County Council would like the MAPP lines to be placed underground or underwater, both of which would add to the cost of the project.

Replacing existing lines with new lines would pump an estimated $260 million into the Sussex County economy during construction, Elliott said. The 27-mile Sussex County line would be built on existing Delmarva Power rights of way and would start in Delmar and pass through Dagsboro en route to the Indian River plant.

Two new poles, made of steel, and foundations will be placed in the same location as the existing poles.

The new poles will range in height from 155 to 165 feet and be about 16 feet apart. The line will terminate at a new AC/DC converter station near the power plant. Construction is expected to begin in 2012 in Sussex County.

Elliott said MAPP would create a bigger pipeline for delivering new, clean energy solutions for an increase in wind, solar and even nuclear energy opportunities.

“MAPP is the most effective way to secure reliable, diverse and low-cost energy for all residents on the peninsula,” Elliott said.

The original project contained another 100 miles of lines north from the Indian River plant to the Salem, N.J., nuclear power plant. Elliott said because of economic reasons that portion of the project was removed. “It was found there was no need to spend the additional money,” he said.
