On August 11, Hazelwood, Missouri-based smart metering system vendor Aclara announced it acquired the smart grid business of Tollgrade, a provider of distribution grid sensors and software for monitoring and analytics. The deal comes just 8 months after Aclara acquired GE’s electric metering business, and all of this in the wake of its own sale to Sun Capital Partners in 2014.
It’s no surprise that Aclara is broadening its portfolio horizons. Upside potential for Aclara’s legacy technology—power line carrier (PLC) communications for smart meter data transfer—is on the wane. While still popular with low density utilities such as rural cooperatives, PLC isn’t as strong a platform for some of the newer smart grid applications that utilities want their advanced metering infrastructure (AMI) networks to support. Aclara has more than 14 million meters in the field and has been looking for growth opportunities since before its sale to Sun Capital.
Aclara has ventured into software, including solutions in the customer engagement and asset planning realms. It also offers several wireless communications solutions as an alternative to its enhanced Two-Way Automatic Communications System (eTWACS) PLC offering. These include cellular solutions and its Synergize RF point-to-multipoint system for utilities. But with the addition of GE’s meter business and now a leading line sensor/grid monitoring solution provider, Aclara has (or will have, presumably) a far more integrated set of products to offer. That means greater customer retainment.
The LightHouse product line also provides Aclara with an entry into the investor-owned utility (IOU) market where it has concentrated its efforts—Tollgrade has deployed its LightHouse system with DTE, Duke Energy, Toronto Hydro, and Western Power in the United Kingdom. In theory, Aclara can now better promote its various AMI solution sets to electric IOUs while marketing the LightHouse distribution monitoring solution to its sizable installed base of cooperatives and munis. Aclara historically has had a sizeable presence in the IOU marketplace with its gas and water AMI systems, with millions of endpoint systems deployed with customers in states including California and New York.
It’s All About the Smart
What makes a grid smart is the overlay of communications and software solutions that allow formerly manual controls to be automated. While Aclara was offering a piece of that smart equation with its legacy communications system, it now offers a broader array of solutions to smarten up not only the meters at the very edge of the grid, but also feeders throughout a distribution network.
The line sensor market hasn’t exactly taken the world by storm in the last few years, but it has shown promising traction more recently. Where the devices used to be expensive and analytics solutions (from which the return on sensor investments really come) were nascent, today’s costs are lower and the ways that real-time operational data can be used are growing exponentially. Navigant Research expects the global installed base of overhead line monitors to grow from a couple hundred thousand in 2016 to around 1.7 million by 2025.

Generally, we don’t expect the overhead line monitor business to reach the same levels of penetration as, say, smart meters. They’ll be used on particularly troublesome feeders or where there are high levels of distributed solar wreaking havoc at the grid edge.
The Internet of Energy
What Aclara is doing by consolidating various sensors types—and a meter is just another sensor in the grid—into its product line is demonstrating its commitment to going beyond meter reading and boldly into the broader Internet of Things—or Energy—to make its platform more valuable and deepen its reach with utility decision makers. I wouldn’t be surprised to see more announcements from Aclara, perhaps related to software or analytics that leverage the underlying network and devices now incorporated in the company’s stable of products.
