Canada’s Commercial & Industrial Energy Storage Market 2026: The Definitive Guide to Policy, Procurement, and Project Execution

Canada’s commercial and industrial (C&I) energy storage market has reached an inflection point. What was once an early-adoption frontier defined by pilot projects and cautious capital has matured into a high-growth, high-certainty deployment environment backed by federal investment tax credits totaling up to 45%, provincial procurement programs delivering 22-year fixed-revenue contracts, and a pipeline of over 25 GW of storage capacity awaiting interconnection.

The numbers tell the story: Canada’s behind-the-meter (BTM) stationary battery storage market is projected to grow from CAD 1.2–1.6 billion in 2026 to CAD 4.5–6.0 billion by 2035. The industrial-scale stationary storage market—encompassing front-of-the-meter utility assets and large C&I installations—is forecast to expand from CAD 1.8–2.2 billion in 2026 to CAD 8–12 billion by 2035. C&I systems in the 30 kWh to 5 MWh range account for over 55% of total BTM market value.

This guide is designed as the authoritative reference for project developers, facility owners, engineering procurement and construction (EPC) firms, and investors navigating the Canadian C&I energy storage landscape in 2026. We address the six critical pain points that define project success or failure in this market: interconnection delays, ITC maximization, IESO procurement participation, installer shortages, supply chain risk, and extreme climate resilience.

Part I: Market Overview – The Tipping Point Has Arrived

1.1 Market Size and Growth Trajectory

The Canadian energy storage market is no longer speculative—it is delivering measurable returns across every segment. The BTM stationary battery storage market alone is on track to reach CAD 4.5–6.0 billion by 2035, representing a compound annual growth rate that places Canada among the fastest-growing energy storage markets in North America.

Table 1: Canada Stationary Battery Storage Market Forecast (2026–2035)

Sources: IndexBox Market Reports (2026)

Several structural drivers underpin this growth:

• Rising electricity rates across all provinces are making behind-the-meter storage economically compelling for commercial and industrial energy consumers.

• Demand charge exposure—particularly in Ontario, Alberta, and British Columbia—creates immediate, quantifiable savings for C&I facilities that deploy storage to shave peak loads.

• Federal and provincial incentive programs have compressed payback periods from 10–14 years in 2020 to 6–10 years for typical C&I applications today.

• Corporate sustainability commitments are driving demand for storage-backed renewable energy, with data center operators and industrial facilities entering long-term offtake agreements.

1.2 Technology Roadmap: LFP Dominance and Cost Declines

Lithium Iron Phosphate (LFP) chemistry has decisively won the technology battle for Canadian C&I energy storage applications. LFP now accounts for 80–85% of new BTM installations and over 80% of system contracts signed in 2025–2026, displacing Nickel Manganese Cobalt (NMC) on safety, cycle life, and cost grounds.

The cost trajectory is equally compelling. Average installed costs for C&I systems in 2026 are estimated at CAD 800–1,100 per kWh, representing a 25–30% decline since 2022. At the cell level, LFP prices have fallen below USD 90/kWh, making the chemistry increasingly dominant across residential, C&I, and utility-scale applications.

Sources: IndexBox Market Reports (2026)

Containerized BESS solutions now represent approximately 75% of new utility-scale procurements, favored for faster deployment and standardized manufacturing. For C&I applications, outdoor cabinet solutions ranging from 100 kW/232 kWh to 125 kW/261 kWh are gaining preference for their modularity, rapid deployment capability, and reduced site preparation requirements.

1.3 Regional Deployment Landscape

Ontario continues to lead Canada’s energy storage deployment through the Independent Electricity System Operator’s (IESO) Long-Term procurement framework. The province has now procured approximately 3.6 GW of utility-scale battery storage capacity through LT1 and LT2 programs. The LT2 Capacity Window 1, with results announced on June 16, 2026, secured 640 MW of eight-hour battery storage across three projects—all featuring 50% Indigenous equity ownership.

Alberta is emerging as a significant market through the Alberta Utilities Commission’s approval of multiple solar-plus-storage projects, including Red Willow (225 MWac + 200 MWh) and Dolcy (300 MWac + 200 MWh). The province’s deregulated electricity market creates merchant revenue opportunities that complement capacity payments.

British Columbia is advancing BTM energy storage deployment through BC Hydro partnerships, including collaboration with Ameresco on distributed storage initiatives. The province’s CleanBC roadmap and carbon pricing framework further support energy storage adoption.

Prince Edward Island is actively seeking a 10–50 MW energy storage facility operator, signaling Maritime provinces’ growing interest in storage as a grid reliability tool.

Part II: Policy Framework – The 45% ITC Opportunity

2.1 Clean Technology Investment Tax Credit (CTITC) – 30%

The Clean Technology Investment Tax Credit provides a refundable 30% credit on the capital cost of eligible clean technology property, including solar PV systems, stationary electricity storage, and related equipment. Key features include:

• Eligibility period: Property acquired and available for use between March 28, 2023, and before 2034.

• Credit rate: 30% through 2033; reduced to 15% for assets commissioned in 2034.

• Labour requirements: To receive the full 30% rate, projects must comply with prevailing wage and apprenticeship requirements. Non-compliance triggers a 10% rate reduction.

• Refundability: 40% of the credit is refundable for corporations—paid even with no tax liability.

• Eligible equipment: Solar PV panels, inverters, mounting systems, electrical wiring, switchgear, and stationary battery storage installed as part of the solar project.

2.2 Clean Electricity Investment Tax Credit (CEITC) – 15%

The Clean Electricity Investment Tax Credit, enacted through Bill C-15 in March 2026, provides an additional refundable 15% credit for investments in low-emitting electricity generation systems and stationary electricity storage systems that do not use fossil fuels in operation.

Critical distinctions from the CTITC:

• Broader eligibility: Available to non-taxable entities including municipalities, utilities, and Indigenous-owned corporations.

• Project scope: Covers stationary electricity storage systems regardless of whether they are co-located with generation.

• Lifetime value: The Canadian government estimates the CEITC will provide CAD 27.3 billion in support over its lifetime.

2.3 Domestic Content Requirement (DCR) – What You Need to Know

The Government of Canada conducted a public consultation from February 13 to March 13, 2026, on the potential introduction of a domestic content requirement (DCR) for the Clean Technology and Clean Electricity ITCs.

While the DCR has not yet been finalized, the consultation signals a clear direction: future access to full ITC rates may require a minimum percentage of Canadian content in eligible equipment. The consultation explored application to structural steel, advanced manufactured products (including photovoltaic modules and battery modules), and other components.

For project developers and asset owners, this means:

• Procurement strategy matters: Sourcing decisions made today will affect ITC eligibility if DCR is adopted retroactively or with a phase-in period.

• Documentation is critical: Country-of-origin certification and supply chain traceability will become essential compliance requirements.

• Localization is a hedge: Engaging with Canadian module assembly and system integration partners reduces DCR risk while supporting domestic supply chain development.

2.4 Accelerated Capital Cost Allowance (CCA)

In addition to the ITC stack, eligible clean energy equipment qualifies for Class 43.1 CCA with 100% immediate expensing for property available for use before 2030. This accelerated depreciation provides significant near-term tax relief, further improving project economics.

Part III: IESO Long-Term Procurement – The 22-Year Revenue Anchor

3.1 The LT1 and LT2 Framework

Ontario’s IESO has established North America’s most robust long-term energy storage procurement framework. The LT1 procurement—the largest battery storage procurement in Canadian history—awarded over 850 MW of BESS capacity contracts across two tranches in 2023.

The LT2 procurement, announced in August 2024, aims to procure 3 TWh of energy generation alongside 600 MW of new capacity resources. The first capacity window results were announced on June 16, 2026, securing 640 MW of eight-hour battery storage across three projects.

3.2 The $1,221/MW/Day Contract Structure

The IESO’s capacity contracts provide a fixed monthly capacity payment indexed to inflation. For the E-LT1 program—under which PowerBank’s SFF-06 project secured a 22-year contract—the payment structure is CAD 1,221 per MW per business day.

This contract structure offers:

• 22-year revenue certainty: Fixed capacity payments provide bankable, predictable cash flows.

• Inflation protection: Indexed payments maintain real value over the contract term.

• Performance incentives: Non-performance charges provide accountability while rewarding reliable operation.

3.3 Indigenous Partnership Requirements

A defining feature of Ontario’s energy storage procurement is the emphasis on Indigenous equity participation. All three LT2 Capacity Window 1 projects feature 50% Indigenous equity ownership. The SFF-06 project is held 50% by PowerBank and 50% by a partnership of First Nations communities in Ontario.

For project developers, this creates both a requirement and an opportunity:

• Competitive advantage: Proposals with meaningful Indigenous partnership are strongly preferred in IESO evaluations.

• Community benefits: Indigenous ownership delivers direct economic benefits to local communities and strengthens project social license.

• Financing access: Indigenous partnerships can unlock additional financing sources and de-risk projects.

3.4 LT2 Window 2 and Beyond

IESO is planning multiple additional RFP windows under the LT2 umbrella. Window 2 proposal submission is now targeted for Q2 2027, with commercial operation milestones pushed to 2032. The Long Lead-Time RFP, launched in May 2026, aims to procure up to 800 MW of long-duration energy storage.

For C&I energy storage providers, the LT2 framework represents a multi-year opportunity pipeline with predictable procurement cycles and transparent evaluation criteria.

Part IV: Major Operational Projects – The Market in Action

4.1 PowerBank SFF-06 – A Template for Success

The SFF-06 project, now in commercial operation in Cramahe, Ontario, exemplifies the successful execution model for Canadian energy storage projects. Key attributes include:

• Capacity: 4.99 MW battery energy storage system

• Contract: 22-year IESO E-LT1 contract at CAD 1,221/MW/day

• Co-location: Operates at the site of an existing ground-mount solar project

• Ownership: 50% PowerBank, 50% First Nations communities

• Financing: CAD 28.1 million loan facility from Royal Bank of Canada

The SFF-06 project demonstrates the viability of solar-plus-storage co-location, the bankability of IESO contracts, and the replicability of Indigenous partnership models.

4.2 LT2 Capacity Window 1 Projects

The three projects selected in the LT2 Capacity Window 1 represent a new benchmark for Canadian energy storage deployment:

• Total capacity: 640 MW of eight-hour battery storage

• Indigenous equity: 50% across all projects

• Cost reduction: BESS capacity costs are 36% lower than Expedited-LT1 and 16% lower than LT1 procurement

• Contract term: 20-year contracts with commercial operations expected by May 1, 2030

4.3 Trail Road BESS – Ottawa’s Flagship Project

Scout Clean Energy has begun construction on the 150 MW Trail Road BESS in Ottawa, a joint venture with the Algonquins of Pikwàkanagàn First Nation. The project represents the growing trend of utility-scale energy storage deployment in Eastern Ontario and the deepening integration of Indigenous partnerships.

Part V: The Six Critical Pain Points – Solutions for 2026

Pain Point 1: Interconnection Queues – The 3- to 5-Year Bottleneck

The Problem

Grid interconnection queue delays averaging 3–5 years for large projects represent the single largest bottleneck to energy storage deployment acceleration in Canada. Over 25 GW of proposed storage capacity is awaiting connection approval. The queue-based processing model, while transitioning toward “first-ready, first-served” approaches, still creates multi-year delays that threaten project viability.

The Solution: Behind-the-Meter Deployment

BTM energy storage systems bypass the interconnection queue entirely by operating behind the customer’s existing utility meter. A BTM system can be deployed in weeks to months, not years, providing immediate energy cost savings and demand charge reduction while the interconnection process runs in parallel for any future grid services.

Key considerations for BTM deployment:

• Existing infrastructure: BTM systems connect at the low- or medium-voltage level, requiring no new transmission infrastructure.

• Phased approach: Deploy BTM storage now for immediate savings; add grid services later when interconnection is secured.

• Solar co-location: Over 60% of new BTM storage installations in 2026 are co-deployed with rooftop or ground-mount solar PV, leveraging existing solar infrastructure.

The MateSolar Advantage

Our Commercial 500KW Hybrid Solar System is designed for seamless integration with existing solar PV installations, enabling rapid BTM deployment without interconnection delays. For customers requiring grid services, our systems are engineered with the flexibility to add grid-facing functionality once interconnection is approved.

Pain Point 2: ITC Maximization – Turning 45% into Reality

The Problem

The federal ITC stack offers up to 45% in tax credits, but the application process is complex and the Canada Revenue Agency (CRA) employs strict pre-audit mechanisms. Documentation is the single most important success factor—and the most common point of failure.

The Solution: Comprehensive ITC Readiness

Documentation requirements:

• Eligibility documentation: Prove that property is new, acquired within the eligible period, and available for use in Canada.

• Labour compliance documentation: Demonstrate prevailing wage payments and apprenticeship hour compliance to secure the full 30% CTITC rate.

• Cost tracking: Maintain detailed records of capital costs—labour costs are not eligible for the ITC, only equipment capital costs qualify.

• Timing documentation: Credits must be claimed within 18 months of the end of the tax year in which the asset became available for use.

DCR preparedness:

• Supply chain mapping: Document the origin of all major components (cells, modules, inverters, structural steel).

• Localization strategy: Engage Canadian module assembly and system integration partners to build domestic content.

• Flexible sourcing: Maintain relationships with suppliers in multiple jurisdictions to adapt to changing requirements.

Project structure optimization:

• Entity selection: Taxable Canadian corporations can access both CTITC and CEITC; non-taxable entities (municipalities, Indigenous corporations) can access CEITC.

• Phased commissioning: Stagger project commissioning to optimize credit timing across tax years.

• Credit stacking: Combine ITC with accelerated CCA (100% first-year expensing) for maximum near-term tax relief.

Pain Point 3: IESO Long-Term Procurement – Securing 22-Year Revenue

The Problem

IESO’s 22-year fixed capacity payment contracts provide North America-rare long-term revenue certainty. But the LT2 procurement window is highly competitive, and successful participation requires proven experience, Indigenous partnership capability, and technical performance guarantees.

The Solution: Proven IESO Readiness

IESO experience matters: PowerBank’s SFF-06 project, which secured a 22-year IESO contract through the E-LT1 RFP, demonstrates the viability of C&I-scale energy storage in IESO procurement.

Key success factors for IESO participation:

• Technical performance: 22-year contracts require BESS systems with ultra-long cycle life and minimal degradation. LFP chemistry, with its 6,000+ cycle capability at 80% depth of discharge, is the only viable chemistry for 20+ year contracts.

• Indigenous partnership: Proposals with 50% Indigenous equity ownership are strongly preferred. Engage with First Nations communities early in the project development process.

• Municipal support: LT2 requires Municipal Support Resolutions (MSR) for proposal submission. Build community relationships before the RFP is issued.

• Financing readiness: 22-year contracts require project financing structures that match the contract term. Engage lenders early in the development process.

Contract Performance Guarantee:

• System redundancy: Design BESS systems with N+1 redundancy to ensure performance availability over the full contract term.

• Performance monitoring: Deploy advanced energy management systems with predictive analytics to identify and address performance degradation before it impacts contract compliance.

• Maintenance planning: Establish long-term operations and maintenance (O&M) agreements that align with the contract duration.

Pain Point 4: Installer Shortages – The 1,500–2,000 Person Gap

The Problem

Canada faces a shortage of 1,500–2,000 qualified battery storage installers, with training pipelines requiring 12–18 months to produce skilled workers. The industry is growing faster than the talent pool, creating project execution risk.

The Solution: Turnkey Delivery and Factory Pre-Integration

One-stop turnkey service: In the current installer shortage environment, customers need more than equipment—they need complete project delivery. Turnkey solutions that include engineering, procurement, construction, and commissioning reduce the burden on scarce local installation resources.

Factory pre-integration and pre-commissioning: Outdoor cabinet and containerized BESS solutions that are factory-assembled, pre-wired, and pre-commissioned dramatically reduce on-site installation requirements. Our 100kW/232kWh and 125kW/261kWh Liquid-Cooled Outdoor Cabinets arrive on-site as complete, tested systems requiring only electrical connection and final commissioning.

Remote commissioning and training: Remote commissioning support reduces the need for on-site technical resources. Training programs for local installation partners build long-term capacity while enabling immediate project execution.

The MateSolar Turnkey Advantage

Our solutions are designed for rapid deployment with minimal on-site expertise:

• 40Ft 1MWh/2MWh Air-Cooled Container ESS: Factory-assembled and tested, ready for plug-and-play deployment

• 100kW/232kWh & 125kW/261kWh Outdoor Cabinets: Modular, scalable, and pre-integrated for commercial applications

Pain Point 5: LFP Supply Chain Risk – 90% Import Dependency

The Problem

Canada imports over 90% of its battery cells from Asia, with over 85% of global LFP cathode material production concentrated in China. Lithium and graphite prices fluctuate 30–50% year-over-year, creating significant project economic risk.

The Solution: Diversified Supply and Price Protection

Multi-source supply chain: Engage with suppliers in multiple jurisdictions—China, South Korea, and emerging North American sources—to reduce concentration risk. While Canada remains structurally import-dependent, domestic module assembly and system integration capacity is expanding rapidly in Ontario, Quebec, and British Columbia.

Domestic assembly capability: Canadian module assembly and system integration reduces reliance on fully imported systems. Partners with Canadian assembly facilities can provide domestic content that positions projects favorably for potential DCR requirements.

Price locking mechanisms: Long-term framework agreements with fixed or indexed pricing protect against battery price volatility. Volume commitments and multi-year agreements provide suppliers with visibility while securing predictable costs for project developers.

Emerging domestic supply: Canadian companies are developing domestic LFP cathode production capability, with initial commercial supply agreements targeted for energy storage applications by the end of 2026. While early-stage, these developments signal a long-term trend toward supply chain localization.

Pain Point 6: Extreme Climate – -40°C to +40°C Performance

The Problem

Canada’s climate extremes—winter temperatures as low as -40°C and summer highs exceeding +40°C—create unique technical challenges for battery energy storage systems. Customers’ most direct concern is simple: Will the battery work when it’s 40 below?

The Solution: Climate-Engineered Systems

Wide operating temperature range: BESS equipment must be rated for operation across the full Canadian climate spectrum. Systems should maintain charge/discharge efficiency at -40°C through active heating systems that keep cells within optimal operating ranges.

Intelligent thermal management: Active heating and cooling systems maintain cell temperatures within the optimal 15–35°C range regardless of ambient conditions. Liquid cooling systems provide superior temperature uniformity compared to air cooling, particularly important for high C-rate applications and extreme ambient temperatures.

Environmental protection: IP54 or NEMA 3R minimum protection ratings ensure resistance to ice, snow, freezing rain, salt fog, and humidity. Enclosures must be designed to prevent moisture ingress that could compromise electrical systems.

Cold-weather performance validation: System designs should be validated through third-party testing at extreme temperatures. UL 9540 certification, while primarily focused on safety, provides assurance of system integrity under extreme conditions.

Part VII: Frequently Asked Questions

FAQ 1: What is the difference between CTITC and CEITC, and can I claim both?

A: Yes, you can claim both credits on the same project if you meet the eligibility requirements for each. The CTITC (30%) applies to eligible clean technology property acquired and available for use between March 28, 2023, and before 2034. The CEITC (15%) applies to stationary electricity storage systems that do not use fossil fuels in operation. Taxable Canadian corporations can access both credits; non-taxable entities (municipalities, utilities, Indigenous corporations) can access the CEITC. Combined, the two credits can offset up to 45% of eligible capital costs.

FAQ 2: How long does it take to deploy a BTM C&I energy storage system in Canada?

A: BTM systems can be deployed in weeks to months, compared to 3–5 years for interconnection-dependent utility-scale projects. The exact timeline depends on site preparation requirements, equipment lead times, and local permitting. Factory pre-assembled solutions like our outdoor cabinets and containerized systems can reduce deployment time by eliminating on-site assembly and testing.

FAQ 3: What happens if the Domestic Content Requirement (DCR) is introduced?

A: The Government of Canada completed a public consultation on DCR in March 2026. If adopted, full ITC rates may require a minimum percentage of Canadian content in eligible equipment. To hedge against this risk, we recommend:

• Documenting the origin of all major components

• Engaging Canadian module assembly and system integration partners

• Maintaining flexible supply chain relationships

• Monitoring government announcements for final DCR rules

FAQ 4: Can BTM storage participate in IESO capacity markets?

A: Yes. BTM storage systems can participate in IESO capacity markets if they meet the technical requirements and are aggregated to sufficient scale. The IESO’s LT1 and LT2 procurements have included BTM-scale projects, and virtual power plant (VPP) aggregation is emerging as a pathway for smaller systems to access capacity revenues.

FAQ 5: How does extreme cold affect battery performance?

A: LFP batteries can operate at -40°C with proper thermal management. Active heating systems maintain cells within optimal operating ranges, preserving charge/discharge efficiency. Our liquid-cooled systems provide superior temperature uniformity, ensuring reliable performance across Canada’s full climate spectrum. Enclosures with IP54 or NEMA 3R ratings protect against ice, snow, and moisture ingress.

FAQ 6: What is the typical payback period for a C&I energy storage system in Canada?

A: With the combined 45% federal ITC and accelerated CCA, typical C&I project payback periods have compressed from 10–14 years in 2020 to 6–10 years in 2026. Actual payback depends on system size, electricity rates, demand charge exposure, and provincial incentives.

FAQ 7: How does the 22-year IESO contract work?

A: The IESO capacity contract provides a fixed monthly capacity payment, typically CAD 1,221/MW per business day, indexed to inflation. The contract term is 20–22 years. Payments are subject to performance adjustments—non-performance charges are deducted from the monthly payment. Projects must achieve commercial operation by the specified milestone date to avoid default.

FAQ 8: What is the current installed cost for C&I energy storage in Canada?

A: Average installed costs for C&I systems in 2026 are estimated at CAD 800–1,100 per kWh. Utility-scale systems range from CAD 550–750 per kWh. Costs have fallen 25–30% since 2022 and are projected to reach CAD 500–700 per kWh by 2030.

FAQ 9: What safety certifications are required for BESS in Canada?

A: Battery energy storage systems must comply with UL 9540 (energy storage systems and equipment) and NFPA 855 (installation of stationary energy storage systems). These certifications add 6–12 months to project timelines. Working with suppliers who have pre-certified systems can significantly reduce this timeline.

FAQ 10: How can I participate in future IESO LT2 windows?

A: Future LT2 windows will be announced by IESO. Key preparation steps include:

• Securing Municipal Support Resolutions (MSR) early

• Developing Indigenous partnership proposals (50% equity preferred)

• Engaging project financing lenders

• Selecting BESS technology with 20+ year performance capability

• Monitoring IESO announcements for RFP timelines

Part VIII: Strategic Recommendations for 2026–2027

For Commercial and Industrial Facility Owners

Act now on BTM deployment: With 6–10 year paybacks and 45% ITC availability, the economic case for C&I energy storage has never been stronger. BTM systems bypass interconnection queues, delivering immediate savings while positioning facilities for future grid service revenues.

Maximize the ITC stack: Work with tax advisors who understand CTITC and CEITC requirements. Document everything—the CRA’s pre-audit approach means documentation is your strongest defense.

Consider solar-plus-storage: Over 60% of new BTM installations are co-deployed with solar PV. Existing solar arrays can be retrofitted with storage for enhanced economics.

For Project Developers

Engage Indigenous partners early: IESO procurements strongly prefer projects with 50% Indigenous equity. Early engagement builds relationships and strengthens proposals.

Prepare for DCR: Even before final rules are announced, supply chain documentation and localization strategies reduce risk and position projects favorably.

Design for 20+ years: IESO contracts require 20–22 year performance. Select LFP chemistry with 6,000+ cycle capability and design systems with redundancy for long-term reliability.

For EPC Firms and Installers

Invest in training: The 1,500–2,000 installer gap represents both a challenge and an opportunity. Firms that build training capacity will capture market share.

Leverage pre-integrated solutions: Factory pre-assembled systems reduce on-site installation requirements, enabling more projects with limited skilled labor.

Build remote commissioning capability: Remote commissioning and support reduce the need for on-site technical resources while enabling faster project delivery.

Conclusion: The Canadian energy storage Opportunity

Canada’s commercial and industrial energy storage market has reached a defining moment. With federal ITC support totaling up to 45%, provincial procurement programs delivering 22-year revenue certainty, and technology costs declining to CAD 800–1,100 per kWh, the fundamental economics of C&I energy storage have never been more compelling.

The challenges are real—interconnection queues averaging 3–5 years, installer shortages exceeding 1,500 skilled workers, supply chain concentration in Asia, and climate extremes from -40°C to +40°C. But these challenges are solvable through strategic BTM deployment, turnkey project delivery, diversified supply chains, and climate-engineered system design.

The projects are already delivering results. PowerBank’s SFF-06 project is in commercial operation under a 22-year IESO contract. LT2 Capacity Window 1 has secured 640 MW of new battery storage. Ontario has now procured 3.6 GW of utility-scale storage capacity. The market is not coming—it is here.
