If the portfolio of a corporate venture capital firm can be taken as a signal for the strategic priorities of their parent companies, then National Grid has high hopes for automation as the future of the utility industry.

The heavy emphasis on automation and machine learning from one of the nations largest privately held utilities with a customer base numbering around 20 million people is significant. And a sign of where the industry could be going.

Since its launch, National Grids venture firm, National Grid Partners, has invested in 16 startups that featured machine learning at the core of their pitch. Most recently, the company backed AI Dash, which uses machine learning algorithms to analyze satellite images and infer the encroachment of vegetation on National Grid power lines to avoid outages.

Another recent investment, Aperio, uses data from sensors monitoring critical infrastructure to predict loss of data quality from degradation or cyberattacks.

Indeed, of the $175 million in investments the firm has made, roughly $135 million has been committed to companies leveraging machine learning for their services.

AI will be critical for the energy industry to achieve aggressive decarbonization and decentralization goals, said Lisa Lambert, the chief technology and innovation officer at National Grid and the founder and president of National Grid Partners.

National Grid started the year off slowly because of the COVID-19 epidemic, but the pace of its investments picked up and the company is on track to hit its investment targets for the year, Lambert said.

Modernization is critical for an industry that still mostly runs on spreadsheets and collective knowledge that has locked in an aging employee base, with no contingency plans in the event of retirement, Lambert said. Its that situation thats compelling National Grid and other utilities to automate more of their business.

Most companies in the utility sector are trying to automate now for efficiency reasons and cost reasons. Today, most companies have everything written down in manuals; as an industry, we basically still run our networks off spreadsheets, and the skills and experience of the people who run the networks. So weve got serious issues if those people retire. Automating [and] digitizing is top of mind for all the utilities weve talked to in the Next Grid Alliance.

To date, a lot of the automation work thats been done has been around basic automation of business processes. But there are new capabilities on the horizon that will push the automation of different activities up the value chain, Lambert said.

ML is the next level predictive maintenance of your assets, delivering for the customer. Uniphore, for example: youre learning from every interaction you have with your customer, incorporating that into the algorithm, and the next time you meet a customer, youre going to do better. So thats the next generation, Lambert said. Once everything is digital, youre learning from those engagements whether engaging an asset or a human being.

Lambert sees another source of demand for new machine learning tech in the need for utilities to rapidly decarbonize. The move away from fossil fuels will necessitate entirely new ways of operating and managing a power grid. One where humans are less likely to be in the loop.

In the next five years, utilities have to get automation and analytics right if theyre going to have any chance at a net-zero world youre going to need to run those assets differently, said Lambert. Windmills and solar panels are not [part of] traditional distribution networks. A lot of traditional engineers probably dont think about the need to innovate, because theyre building out the engineering technology that was relevant when assets were built decades ago whereas all these renewable assets have been built in the era of OT/IT.
