Athena Smart
Energy Software

Get more value from your energy investments with Athena, Stem’s intelligent software solution

How Athena Works

Athena leverages best-in-class data engineering, forecasting, and optimization to maximize ROI and performance for every system in our network.

It all starts with predictions. Athena’s machine learning algorithms generate multiple forecasts – about weather, prices, solar generation, energy demand, and other factors – and analyze how energy assets can capture value at different times. Athena then formulates a strategy for maximizing that value, and implements it in a variety of ways: by bidding assets into wholesale markets, charging and discharging batteries, injecting solar energy into the grid or storing it for later, allowing EVs to charge now or overnight. And because Athena constantly monitors system performance, it adjusts to changing circumstances in real time.

Stem tunes Athena’s algorithms according to each customer’s priorities and goals, whether it’s an independent power producer’s bidding strategy in a wholesale market, or a water district’s need for backup power, or a facility’s goal to reduce GHG emissions. From there, Athena automates everything that’s involved with maximizing asset performance and ROI, including interfacing with wholesale markets and utilities, integrating and optimizing various assets and value streams, and complying with incentive and warranty requirements.

Regardless of a project’s type or location, Athena leverages the same machine learning algorithms that have delivered industry-leading performance for over a decade. And with deep insights gained from tens of millions of system runtime hours, Athena’s continuous improvement translates into more value for Stem’s customers and partners.

Athena Solutions & Services

Front of Meter Wholesale Market Participation

Project developers and asset owners use Athena to optimize power generation and market participation revenues of both standalone energy storage and hybrid solar plus storage power plants. Services include market revenue optimization, incentive management, solar clipping, and solar self-consumption.

Behind the Meter
Standalone Storage

With standalone battery storage, Athena forecasts building loads and optimizes when to draw energy from the grid or the battery based on local energy rates. It considers customer demand charges, time-of-use rates, available utility and market programs, and any other incentive programs. Services include utility bill optimization, demand response, market revenue optimization, and incentive management.

Behind the Meter Solar Plus Storage

Businesses with solar and storage can use Athena to forecast solar generation and unlock the value of investment tax credits (ITC), compliance requirements, state incentives, and tariffs by maximizing solar battery charging and time-shifting solar generation to when it’s most valuable. Services include utility bill optimization, incentive management, solar clipping, and solar self-consumption.
