Distributed Energy Resources (DER) play a critical role in modern power systems as grids decentralise and electrification accelerates. As energy independence becomes central to decarbonisation strategies, investment in DER offers clear insight into how this transition is unfolding.
Capital allocation highlights which DER solutions are scaling most rapidly, where infrastructure readiness is influencing funding decisions. These investment patterns clarify how funding dynamics are shaping the next phase of decentralised energy adoption.
This article examines funding trends in DER across technologies, regions, and investor types. It is the final article in our Distributed Energy Resources Series, building on earlier coverage of DER innovation, startup activity, and commercial agreements.
Equity funding totals $14 billion invested since 2020
Funding in the DER sector remains predominantly equity-led from 2020 to 2025. Equity has been the primary funding source across the period, totalling $14 billion, compared to $2.3 billion in debt financing.
Equity investment accelerated sharply in 2021, rising from $0.5 billion in 2020 to over $3 billion, marking the sector’s strongest expansion phase. From 2022 onward, equity funding shows moderate fluctuations, with a notable decline in 2024 to $1.8 billion.
This contraction was partially offset by a surge in debt financing, which reached a peak of $1.0 billion in 2024. By 2025, equity funding rebounded, with debt firmly established in the capital mix.
Grant funding remained relatively modest, averaging $25–30 million annually. However, 2023 and 2024 stand out, with grant allocations exceeding $100 million, reflecting targeted public support during this period.
Deal activity in the DER sector increased steadily between 2020 and 2023, driven primarily by pre-seed, seed, and early-stage rounds. Early-stage deal volumes peaked in 2023, indicating strong startup formation and investor engagement.
From 2024 onward, total deal counts declined, with a sharper pullback at the earliest stages. Late-stage activity proved more resilient and rebounded in 2025, highlighting a shift toward capital concentration in fewer companies with demonstrated traction and scale potential.
North America and Europe dominate funding
Investment in DER remains geographically concentrated, with North America and Europe accounting for the majority of funding between 2020 and 2025. North America leads decisively, driven by the United States, which shows strong funding peaks in 2021 and a renewed acceleration from 2024 into 2025. Europe ranks second, with the United Kingdom and Germany emerging as the most active country-level contributors, supported by policy-led deployment across mature DER markets.
Asia shows the most consistent emerging momentum. Funding growth is evident across Japan, India, and Singapore, signalling increasing adoption of DER solutions, although average deal sizes remain smaller than in North America and Europe. This pattern reflects early scaling rather than full commercial maturity.
Other regions, including Oceania and parts of South America, remain marginal in absolute funding terms. However, incremental increases suggest early-stage ecosystem development and growing policy interest rather than large-scale capital deployment.
Overall, the DER investment landscape remains concentrated in a small number of mature hubs, particularly the United States and Western Europe.
Advanced Inverters lead DER solutions by investment
Funding by solution is dominated by Advanced Inverters and Peer-to-Peer Energy Trading, which together account for the largest share of capital deployed across the DER landscape. Advanced Inverters lead with approximately $28 billion in funding, followed closely by Peer-to-Peer Energy Trading at $24 billion. This concentration reflects investor focus on grid and digital energy technologies.
Advanced Inverters show a steady growth curve. Funding rose from $137 million in 2020 to $769 million in 2021, before accelerating to reach $8.98 billion in 2025. This trajectory highlights their central role in enabling grid stability, renewable integration, and bidirectional power flows.
Peer-to-Peer Energy Trading follows a different pattern. After minimal funding of $26 million in 2020, investment surged sharply to $8.41 billion in 2023 and reached $8.78 billion by 2025. Growth is driven by fewer but significantly larger, platform-led investments.
Microgrids rank as the third-largest solution segment, capturing close to $19 billion, or roughly 19.6% of total funding. Investment reflects strong demand for resilience, energy security, and decentralised generation across commercial, industrial, and remote applications.
In contrast, residential and transportation-focused DER solutions attract smaller, steadier capital flows, indicating fragmented markets and slower monetisation. DER Management Systems remain comparatively underfunded, despite their strategic role in coordinating and optimising distributed assets.
Venture capital leads DER deal activity
Venture capital investors are the most active participants in the DER market by deal count, consistently accounting for the largest share of transactions across the period. Deal activity peaks during 2022–2023, and reaches 25 deals a year in 2025.
Corporate investors and Corporate Venture Capital show a rise in participation between 2021 and 2022. This increase signals heightened strategic interest from utilities, energy majors, and industrial players. From 2023 onward, corporate activity levels off toward more focused engagement.
Government-backed programmes maintain a steady but comparatively limited presence in the DER investment landscape. Participation peaks around 2023, consistent with policy-driven funding cycles and targeted innovation incentives, but remains secondary to private capital in shaping overall deal activity.
DER investment shifts toward execution and grid integration
Investment in DER reflects a sector moving decisively from experimentation toward execution. Capital is increasingly directed at solutions that strengthen grid resilience, support electrification, and deliver measurable system value. Equity remains central, but the growing role of debt signals confidence in mature business models and infrastructure-backed deployment.
Capital continues to concentrate in mature regions, particularly the United States and Western Europe, where regulatory frameworks, grid modernisation needs, and commercial demand align. Asia’s steady rise points to growing adoption, but funding remains selective and project-driven.
Progress will depend on execution, system integration, and the ability to translate decentralised assets into reliable, bankable energy outcomes.
