Rhode Island: little state, big energy efficiency opportunity
Rhode Island is often the butt of jokes about its size, a lot of them having to do with an inability among residents to screw in electric light bulbs. But when it comes to energy policy, the state has often loomed large, even if few people notice. For example, it was Rhode Island that led the way with electric industry restructuring in the 1990s. California and Massachusetts usually get the ...

Maryland and the Electron-Hungry Mob
Governments remain in power as long as the people have enough food, or so the old adage goes. But in today’s appliance-driven society, political longevity may depend as much on giving us our daily share of electrons. So it is little surprise that government leaders in Maryland are looking hard for ways to ward off a possible power shortage. Without quick action, the state could face ...

Integrated framework for energy loss allocation in electric distribution systems under liberalised energy markets
This paper discusses an integrated framework for cost allocation of energy losses of electric distribution systems under liberalised energy markets. As key contribution is developed an allocation strategy based upon Locational and Uniform Incremental Prices. The locational incremental prices send efficient economical signals to distributed generators with incentives for loss minimisation and ...

Determining energy savings using utility bills: A winning method for ESCOs
After installing energy conservation measures (ECMs), Energy Service Companies (ESCOs) often determine the energy savings resulting from the project and present the savings results to their customers. A common way tocalculate energy savings is to measure the flows of energy associated with the ECM, and then to apply spreadsheet calculations to determine savings. For example, a chiller retrofit ...

VSEP pre-concentrates black liquor in pulp and paper mills to reduce evaporator load and cut energy costs
As pulp mills have increased production rates to meet market demands, many mills built over the last 20 to 30 years have become limited in evaporator capacity to treat their black liquor volume. The ability to also recover excess liquor from storage areas to higher solids levels is another demand on the evaporators. For mills with outside storage ponds that receive a large amount of rain, the ...

District Energy Comes of Age
Three milestones in 2006 signal new energy for an old idea. When Thomas Edison wrote, “Genius is one percent inspiration, ninety-nine percent persperation,” he could have been describing how hard-working district energy executives feel about their accomplishments in 2006. How else to account for the sense of momentum in a previously-obscure sector of the energy industry that marked its commercial ...

A brighter future for solar in Texas
I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that. - Thomas Edison, in conversation with Henry Ford and Harvey Firestone, 1931 According to the State Energy Conservation Office (SECO), Texas has the greatest solar energy potential of any state in the country. “If photovoltaic (PV) systems operating ...
