Participating in PJM demand response programs is an innovative way for some clients to reduce their electricity bill. Many of our clients have the ability to turn on backup generation or shift or reduce their electric load by altering use of their production equipment or consumption schedule. With our curtailment service provider “partnership”, we have the back office infrastructure and expertise to support demand response activities.

There are three PJM programs to participate in:

Capacity: On average, one 6-hour interruption is called per year, although this can vary from 0 to as many as 10, with a 2–hour advance notice. Payments are made monthly or quarterly, even if no interruptions are called.

Energy: Participant bids load reductions into the real-time or day-ahead market when prices are high.

Synchronous Reserve: Requires fast response within 10 minutes, duration for response is up to ½ hour, the frequency averages 30 times per year and special metering is needed.

What is PJM?

The Pennsylvania-Maryland-New Jersey Interconnection (PJM) has oversight of Generation and Transmission of power throughout much of the mid-Atlantic region. Because of substantial expansion over the past number of years, this Regional Transmission Organization now oversees power delivery to 61 million people. In fact, if PJM were a country it would be the 5th largest electric consumer in the world. Since the nature of electricity is that the power generated must always equal the power consumed, PJM is constantly scheduling its generation resources to match the load.

PJM now also has several Demand-Side Response (DSR) programs in place which can be utilized to help match generation with load. With these programs, energy consumers (end-users) who are able to reduce load and respond quickly, can be “scheduled” by PJM to curtail power just as PJM schedules generation resources to provide power. These DSR programs require that the end user reduce load (or bring on behind-the-meter backup generation) in exchange for direct payments from PJM. Curtailment Service Providers (CSP) partner with REG to administer the programs and work directly with end-users for implementation. Additional metering may be needed and a minimum of 100 kW load reduction is required.

Energy savings brought to light

New fixtures, rebates expected to save Duke Street library $15,000 this year alone.

The problem with an old building is that while it might have been built to appear ornate and majestic, it most likely wasn’t built to be energy efficient.

So when Pennsylvania’s utility rate caps expired in 2010 and the price of electricity began rising, officials at the Lancaster Public Library were worried.

From about $45,000 in 2009, the library’s electric bill rose to $56,000 in 2010 – and was projected to spike to $63,000 this year. With library funding falling, it was an added expense the North Duke Street library simply couldn’t afford.

Ultimately, it didn’t have to.

With the aid of LIVE Green, a Lancaster-based environmental group, and rebates from state-mandated energy conservation programs, the library replaced all of its outdated lighting fixtures with modern, compact fluorescent lighting – which are expected to lower the library’s lighting costs this year by some $15,000.

The new fixtures, installed by Richards Energy Group, Manheim, cost $46,000 – but after rebates they only cost the library $26,000, said library Executive Director Herb Landau.

The library, he noted, will recoup the cost within two to three years.

LIVE Green approached the library after receiving funding through the Lancaster County Community Foundation’s “Green Facilities Program.” This enabled the local environmental organization “to do comprehensive energy assessments of ‘public use buildings’,” said LIVE Green’s Director of Programs Fritz Schroeder. “With the library, we had a number of outdated systems, but lighting is one of the real low-hanging fruits. If your lighting is somewhat outdated, you can really see energy savings almost immediately” by upgrading.

LIVE Green conducted similar assessments for the Lancaster YWCA – which also saw a “big return” by installing new lighting, Schroeder said – and Thaddeus Stevens College of Technology and Susquehanna Association for the Blind & Vision Impaired.

“Sweetening the pot,” Schroeder said, were rebates available from PPL through the state’s Act 129 program, which required electric utilities to reduce customers’ annual electric consumption 1 percent by mid-2011 and 3 percent by mid-2013. As part of that, utilities made rebates on energy-efficient appliances, lighting, and heating and cooling systems; rebates and incentives for home-energy audits; incentives for cutting electricity consumption; and discounted and free compact fluorescent light bulbs.

After the retrofit was completed, PPL sent auditors to inspect the library and ensure the work was done properly before issuing the rebate.

Peter Richards, of Richards Energy Group, said the firm has completed retrofits and rebate applications for more than 75 area projects since May 2009, helping customers reduce their load by more than 1,360 kilowatt-hours, “or about the equivalent of 680 households.”

The company has helped customers get rebates of more than $500,000, with another $117,000 in the queue, he said. Customers include grocery stores, electronics manufacturers, car and tractor dealers, schools, feed mills and retirement communities.

None may need it more than nonprofits squeezed by the economic malaise and subsequent lack of funding.

The Lancaster Public Library’s state funding has been cut by one-third, or $170,000, in the past two years, and city funding has been cut as well. Local fundraising campaigns have helped make up some of the difference.

The library is the county’s largest, serving 40 percent of the population from its downtown location and branches in Leola and Mountville.

It also faces other fiscal hurdles. In May, a huge downpour overloaded a rooftop drain and and funneled water through the second-floor Teen Reading Room and into the Gerald Lestz Reading Room below. Some 500 books – about a quarter of the library’s Lancaster Collection – were soaked. The library sought and received financial gifts – including a $150,000 grant from the Steinman Foundation – to fix the roof. It’s seeking another grant of up to $50,000, and could receive up to $200,000 to help make its roof “green,” planted with vegetation that would absorb rainwater and reduce runoff.

The library is also undergoing a series of renovations, including work on its rooftoop heating, ventilation and air conditioning system, Landau said.

To save money, “we’re putting out fires as they happen,” Landau said. “This building is 57 years old.

“Every little bit helps.”
