An energy usage coordinator controls the energy usage of individual buildings of a group (or portfolio) of buildings in one or more load zones. These buildings have all contracted with an energy company which controls (directly or indirectly) the energy usage coordinator. By agreeing to lower energy usage during times of peak usage (when the energy company may otherwise have to pay very high prices on the spot or short term market), the owners or managers of the buildings receive a preferential energy rate from the energy company. Such a preferential rate may be in the form of a fixed rate reduction or a variable rate reduction. Alternatively, the energy company may determine that the energy is currently selling for twice what its building portfolio has contracted to pay for it so it requests some portion of the portfolio to reduce usage so that it can sell the excess / saved energy in the market.

A gas substitution ratio control system varies natural gas flow to a bi-fuel engine based on detected diesel flow to maintain a desired gas substitution ratio (GSR), without any requirement to sense engine load. In other words, GSR is controlled without monitoring engine load level.

Other embodiments meter gas to maintain the diesel flow rate at the same minimum level for all loads, or meter gas and diesel fuel flows to match a map of the limiting fuel energy based GSR (gas fuel energy rate / total fuel energy rate) at all loads for each engine model.

The present invention is directed to a method of etching anode foil in a non-uniform manner which minimizes thermal oxidation during foil cutting. Having less oxide improves the ability to cut through aluminum anodes with lower energy rates. In aluminum foils, it has been found that a masking step before etching reduces conversion of boehmite aluminum oxide to alpha-phase corundum during laser cutting of anodes, which increases edge quality and productivity. Additionally, the non-etched anode frame allows for less surface area to form during the aging process. As a result, the leakage current is reduced by the proportion of edge to anode surface area, and the aging process will be faster, leading to higher productivity.
