Revenue stacking
Projects combine contracted and merchant revenue streams, each with different risk and price behavior.
BATTERY STORAGE / STRATEGY + OPERATIONS
Merchant revenue is thinning as storage floods the markets that paid most
Battery storage companies develop, integrate, own and operate grid-scale and commercial battery systems that shift energy, provide capacity and stabilize the grid. They earn tolling and capacity contracts, resource adequacy payments and merchant arbitrage and ancillary service revenue, so returns depend on installed cost, revenue contracting, degradation management and access to tax credits.

HOW THE BUSINESS WORKS
How battery storage companies make money.
The revenue streams and structural traits that decide where profit is made and lost in this sector.
Revenue model
- Tolling agreements and capacity contracts with utilities and load-serving entities
- Resource adequacy and capacity market payments
- Merchant energy arbitrage and ancillary services
- Integration, EPC and long-term service agreements
Cell cost and sourcing
Battery cells are the largest equipment cost, and global cell manufacturing is concentrated in China.
Degradation
Usable capacity fades with cycling and age, so projects must budget augmentation to meet contracted obligations.
Tax credit eligibility
The investment tax credit for standalone storage remains central to financing, subject to domestic content and foreign-entity rules.
WHAT TO WATCH
The measures and pressures that matter now.
Five numbers management should review every month, and what is changing in the sector.
- 1
Installed cost per kWh
Determines whether projects can compete for contracts.
- 2
Contracted share of revenue
Measures revenue stability and financeability.
- 3
Round-trip efficiency
Energy lost between charging and discharging is margin lost.
- 4
Availability
Uptime is measured against contractual guarantees and penalties.
- 5
State of health
Remaining capacity relative to the augmentation plan.
Pressures right now
- Rapid storage additions in ERCOT and CAISO have compressed arbitrage spreads and ancillary service prices.
- Foreign-entity restrictions and higher tariffs on Chinese cells are forcing supply chain changes and raising installed costs.
- The Moss Landing battery fire in early 2025 intensified local opposition and fire safety requirements for new projects.
- Utilities and large-load customers are signing more storage tolling contracts to manage peak demand.
WHERE THE VALUE IS
Where battery storage companies find the most value.
The changes that usually move the P&L most in this sector, and the service that delivers each one.
Revenue contracting
Balance tolling, capacity and merchant exposure to match lender and investor risk appetite.
Pricing strategy & discount controlCell and enclosure sourcing
Qualify cell and enclosure suppliers that meet credit rules and negotiate performance warranties.
Procurement & supplier savingsDispatch and augmentation
Optimize dispatch and augmentation timing to protect revenue and stay within warranty terms.
Process & productivity improvementProject portfolio
Decide which projects to build, sell or recapitalize based on contracted returns and interconnection timing.
Portfolio & product-line reviewQuestions leaders in battery storage should be able to answer
- How much of our revenue is contracted, and how sensitive are returns to merchant spreads?
- Does our cell supply meet the foreign-entity rules for the tax credit?
- When will each project need augmentation, and is it in the budget?
