We are all looking for reliable investments these days. If your company is already in the engineering, procurement, and construction (EPC) game, you would do well to consider adding commercial storage. According to the global consultancy Wood Mackenzie (WoodMac), the commercial storage market is set to grow seven-fold over the next five years — from 300MWh of capacity installed to a staggering 2GWh by 2025. That translates into a potential annual market opportunity of $6.9 billion.

This market segment is poised for tremendous growth, and I recommend our EPC partners explore how they might invest some of their resources to position themselves for success in this nascent segment. Let’s go over three recommendations to consider as you explore the market of commercial storage:

1. Educate Yourself

The first thing I recommend is to educate yourself. It sounds simple, but commercial storage is complex, new, and a high-dollar commitment for your customers. Strengthening your expertise will build trust and confidence with your customers. Whether or not a commercial end-user opts to purchase commercial storage, more and more commercial clients are interested in exploring storage and expect an installer to have the knowledge base to speak to the pros and cons storage as a solution.

One of the most impactful and detailed resources you can access would be Stem — one of the pioneers of commercial storage, with more than 10M of system runtime hours and 400MWh+ of capacity deployed through the world. Their Stem University is a free, online learning platform that will help you get up to speed quickly. Whether it’s understanding what a storage system is comprised of, how energy storage makes economic sense, or finding out what the storage incentives are in your state, Stem University has answers for you.

2. Find a Partner You Trust

Finding manufacturing and project partners that you trust goes hand-in-hand with building your expertise and reputation in commercial solar. Look for partners and vendors who have experience and can guide you along the way to your first project. These are people with whom you can discuss and plan with total confidence and whose products have a high-quality standard.

Look for someone who can help you model your project’s cash flows, size your system adequately through EnergyToolbase, or help you with your project’s deployment. This partner should help guide you around the typical pitfalls for industry newcomers.

Like anything in our solar and storage industry, you should prioritize quality and depth of partnership over price. Don’t fight to save a penny at the expense of responsiveness and knowledge. Your first project will be complicated, so don’t go it alone! Demand outstanding performance from your commercial storage partner(s) and deliver excellence to your customer.

3. Focus on the Key Markets

While you may encounter interest from customers across multiple regions you serve, I encourage you to focus your efforts on the region or regions where commercial storage makes the most sense (from an economic and resilience perspective). Pick one or two markets and become an expert. Understand how the incentives drive a return in those markets, the various scenarios which drive revenue streams, and how utilities think about energy storage. Once you master the local context, you can then scale to other geographic markets.

Why geographic markets? Policies and incentives are what enable a commercial storage system to be “in the money,” so you’ll want to invest time to understand the incentives, the policies, and how they differ from state to state. According to WoodMac, there are four major markets for commercial storage at the moment: California, New York, Massachusetts, and New Jersey.

  Projected 2025 forecast Key drivers of growth
California ~800MWh
  • SGIP incentives
  • Demand response auction mechanism
New York ~550MWh
  • Bridge incentive program
  • High demand charge in parts of the state
Massachusetts ~250MWh
  • ACES program
  • MA SMART program
New Jersey ~100MWh
  • Rising interest in resilience
  • State’s storage mandate

Each of the above markets represents a tremendous opportunity. Pick the one that fits your business model over the next few years — especially if you’re already in one of these territories — and concentrate your energy on becoming the source of commercial storage expertise in your community.
