Though energy storage is a relatively new addition to the property operations toolkit, it offers vast potential. Battery systems have demonstrated multiple ways to enhance sustainability, cut costs and supply reliability. A key tactic is load shifting, the process of obtaining power during off-peak hours and storing it for use during costlier peak hours, noted Elliotte Quinn, an energy and construction attorney with Charleston, S.C.-based law firm Parker Poe. Batteries offer an alternative backup strategy to diesel generators, and can store solar power for use at night or on overcast days, Quinn noted. Earlier this year, The Irvine Co. launched a multi-property storage strategy at 21 office towers in Orange County, Calif. When requested by local utility Southern California Edison, the buildings switch their power source from the grid to a storage system that’s powered by Tesla batteries (pictured above). The office portfolio becomes a “virtual power plant that can be used to take the load off the grid instantaneously,” explained Susan Kennedy, CEO of San Francisco-based Advanced Microgrid Solutions, the system’s designer and manager. Shifting to battery power reduces the load by 10 megawatts for as long as four hours to help SCE balance the grid. Wholesale Changes An order issued this year by the Federal Energy Regulatory Commission should make it easier for property owners to sell energy into the wholesale market, but there is a hitch. “If you do that, you’re making yourself subject to federal regulation,” said Quinn. Wholesale selling is likely to be the purview of larger owners, he predicted. As is generally the case with newer technology, battery storage remains a work in progress. By most estimates, costs are dropping, yet the difficulty of predicting payback periods presents a challenge for owners that need to make a multimillion-dollar...

Ways to Reduce Grid Strain
In July, parts of the U.S. saw record demand for electricity, driven by higher temperatures pushing up power usage. Pennsylvania-based regional transmission organization PJM Interconnection LLC reported 144,557 megawatts of demand on July 3, the highest level in almost two years. Power usage in New York City reached its highest level since 2013 the previous day, July 2. On the other coast, more than 80,000 Southern California residents lost power on the July 7-8 weekend as a heat wave caused problems with distribution system equipment. Meanwhile, ERCOT, the grid operator for most of Texas, expects to set a new peak demand record this summer. Resource capacity should allow the grid to operate reliably, but unexpected outages to major generators could prompt demand-side management measures, including potential emergency load shedding. Strain on the grid has obvious implications for property managers, since the residential and commercial sectors account for about 39% of total U.S. energy consumption and more than two-thirds of the electricity used nationwide. Summer heat and havoc it wreaks on the power grid is one reason many property owners seek to incorporate energy efficiency as a core business tenet. One resource in that effort is the Green Lease Leaders program, which encourages lease terms that give both landlords and tenants a stake in adopting building efficiency practices and investments. The Institute for Market Transformation, which administers the Green Lease Leaders program with the U.S. Energy Department’s Better Buildings Alliance, estimates that green leasing could help reduce utility bills by up to $0.51 per square foot (22%) in U.S. office buildings alone; if all leased office buildings executed green leases, the market could achieve over $3 billion in annual energy costs savings. In June, IMT and Better Buildings Alliance recognized companies that incorporated innovative energy...
