,Most commercial buildings are charged by their utility for both the kilowatt-hours (kWh) you use and for your peak electrical load, aka peak demand (kW). We read the tariff books, understand them thoroughly. Sometimes you’re on the wrong rate category already. Sometimes we can achieve enough reductions to change to a reduced rate category.
LED lighting can reduce your kilowatt-hour usage significantly. We’ve seen 10-35% reductions with a full retrofit. And you can choose the kelvin rating of the bulbs, getting just the right light for each room. New car dealerships are especially picky, about both their showroom and lot, as it’s also a showroom. LED lighting is now so sophisticated, the cost so low, it now makes perfect sense. LEDs reduce electrical baseload, so your peak demand gets reduced a bit.
Power Conditioners make your electrical system run more efficiently, reducing both usage and peak. Frankly, there’s a lot of black box junk in this area. We’ve looked at many and, over the years, found the right product. It includes a savings guaranty from the manufacturer. No other energy efficiency equipment we know of does this.
Solar Photovoltaic systems produce electricity, as do wind, hydro, biofuels and Concentrated Heat Power (CHP). Each has its place. Geothermal and solar thermal mostly reduce the natural gas you buy from your utility. As natural gas is artificially cheap because of federal subsidies, it is hard to make such technologies payback fast enough for commercial projects. But there are parts of the country where these techs can be economically brought into a project.
Battery components are seeing an amazing decline in costs, and are viable in some areas of the county now. We can configure the battery system to discharge into leak load periods.
We will select the absolute best combination of technologies to optimize the economics. No one does it better. Few do it at all; they usually stick with their one tech. Most don’t even have the custom modeling tools we’ve developed over the past 12 years to combined usage and demand savings.
