Beyond the Rooftop Rush: How Virtual Power Plants, Green Power Trading, and Load Aggregation Are Reshaping China’s Distributed Solar Industry

The End of the Rooftop-Only Model

China has not run out of rooftops. It is running out of easy economics.

The distinction is important.

During the rapid-growth phase of distributed PV, developers could often create value simply by securing suitable roofs, arranging financing and installing low-cost equipment. The project’s economics were largely determined before the system was connected to a sophisticated electricity-market strategy.

That is no longer sufficient.

As discussed throughout this series, mechanism-price protection is becoming narrower, market electricity prices are becoming more important, time-of-use pricing is changing the economics of daytime solar and local grid conditions increasingly affect project value.

The commercial implication is profound: the industry is shifting from an asset-development business toward an energy-management business.

Virtual Power Plants Are Moving From Concept to Market

A virtual power plant, or VPP, is not a conventional power station. It is a digital and commercial platform that aggregates multiple distributed resources and enables them to operate as a coordinated market participant.

Those resources can include distributed solar, batteries, electric vehicles, industrial loads, commercial buildings, charging infrastructure and other flexible electricity resources.

Jiangsu Province, China provides one of the clearest examples of this transition. In 2026, Jiangsu’s distributed-new-energy aggregation system had developed to the point where 20 virtual power plants were aggregating 1,851 distributed projects, with an aggregated capacity of approximately 3.5318 million kW.

The significance is not the absolute size of the number alone. It is the business architecture behind it.

Individual rooftop projects are often too small to have meaningful market power. Once aggregated, however, thousands of small resources can participate in electricity transactions in a coordinated way.

Jiangsu’s regulators have also been pushing the model beyond a simple aggregation platform. In 2026, the province began encouraging aggregators to evolve toward VPP market entities, with distributed renewable resources participating through aggregation alongside conventional generation in electricity-market transactions.

But Where Does a Virtual Power Plant Actually Make Money?

This is where the VPP story becomes more complicated.

A virtual power plant does not automatically create profit simply because it connects more assets. The operator needs access to actual market revenue streams.

The winners are likely to be companies that can combine technology + electricity trading + customer acquisition + asset operations, rather than companies that only sell VPP software.

Green Power Trading Turns Electricity Into a More Valuable Product

Solar electricity has two potential forms of value.

The first is the electricity itself: the physical energy delivered to the customer or the grid.

The second is the environmental attribute associated with renewable generation.

Green-power trading is where these two dimensions increasingly meet.

Historical Chinese market data have shown green-power environmental premiums in the range of roughly RMB 0.05–0.06/kWh in some southern-market transactions, although investors should not treat that figure as a permanent national premium.

The commercial lesson is more important than the exact number: renewable electricity can have value beyond its physical energy output.

The New Value of Electricity Traceability

For multinational companies, “green” is increasingly becoming a procurement requirement rather than a marketing preference.

Export-oriented manufacturers may need credible evidence of renewable electricity consumption for corporate climate commitments, supply-chain requirements, customer requests and international carbon-accounting systems.

This is particularly important for companies exposed to European markets.

More granular electricity matching and traceability can make renewable-energy procurement easier to document and integrate into corporate emissions-management systems.

That creates a new role for digital energy platforms.

A sophisticated energy-management company can potentially connect physical generation data, electricity-market transactions, customer consumption data and environmental attributes into a single commercial record.

This is one reason why hourly or more granular green-electricity trading is strategically important—even when the exact regulatory requirements differ across jurisdictions and should not be confused with automatic CBAM compliance.

Why China’s 2026 “688” Policy Matters

One of the most significant new developments is China’s policy framework for multi-user green-power direct connection.

In May 2026, the National Development and Reform Commission and the National Energy Administration issued the document commonly referred to as Document 688, formally titled the Notice on Orderly Promoting the Development of Multi-User Green-Power Direct Connection.

The policy expands the practical space for multiple users with green-electricity demand to connect to surrounding renewable-energy resources under defined conditions.

The significance of Document 688 is therefore larger than its direct-connection provisions.

It points toward a future in which the commercial unit is no longer necessarily one rooftop + one customer + one solar project.

Load Aggregation May Become the New Competitive Moat

Solar developers traditionally competed for roofs.

The next generation may compete for loads.

This is a subtle but important shift.

A 5 MW rooftop with weak daytime demand can be less valuable than a smaller rooftop connected to a factory that consumes electricity continuously during solar-production hours.

A developer that controls a portfolio of high-quality industrial loads can potentially create much more value from the same installed PV capacity.

This is particularly relevant in China’s industrial provinces, where large manufacturing clusters create predictable electricity demand.

Jiangsu Province, China is an obvious example. Its 2026 distributed-PV implementation plan explicitly encourages industrial parks to develop distributed solar together with VPP aggregation platforms, participate in demand response and electricity spot markets, and coordinate PV with storage, charging infrastructure and other energy-consuming equipment.

In other words, policy is beginning to recognize the industrial park itself as an energy system.

Solar + Storage Is Moving Toward the Default Architecture

Storage is often presented as the obvious solution to renewable intermittency.

The reality is more complicated.

Batteries only create value when the electricity system provides a way to monetize flexibility.

China’s policy direction increasingly supports this architecture. Jiangsu’s 2026–2030 distributed-PV plan, for example, calls for coordinated development of distributed PV, storage, charging infrastructure and energy-consuming equipment, while encouraging client-side energy-management systems.

After the Industry Shakeout, Who Will Actually Win?

China’s distributed-solar market is unlikely to have one single winner.

Instead, several groups are entering the next phase with very different advantages.

The common characteristic is not ownership of the most rooftops.

China’s Distributed-Solar Experience Is Starting to Travel Overseas

The restructuring of China’s domestic distributed-solar market is also creating a second opportunity: exporting Chinese energy-business models.

Guangdong Province, China provides an early example.

Some Guangdong energy companies are already exploring Southeast Asia and other overseas markets, while private distributed-energy companies are expanding into countries including Thailand, Indonesia and markets in Africa.

The opportunity is not necessarily to export the Chinese rooftop model unchanged.

Instead, Chinese companies can export a more integrated package:

This is potentially important for international investors because the next wave of competition may not simply be between Chinese and foreign solar companies.

It may increasingly be between different energy-service ecosystems.

Why the New Energy Model Is Also Changing Corporate Due Diligence

There is a less obvious consequence of this transformation.

As distributed solar becomes more integrated with electricity trading, VPPs, green-power procurement and industrial customers, the quality of the companies operating the system becomes increasingly important.

An overseas investor evaluating a Chinese energy company can no longer look only at its registered capital and business license.

The relevant question becomes: Can this company actually operate in the new electricity-market environment?

This creates a new concept of corporate credit for the energy-transition economy.

The value of a company is increasingly connected to its market capabilities, not just its legal existence.

The Distributed Solar Business Model of the Future

If the first decade of China’s distributed solar industry was about capacity expansion, the next decade will be about system optimization.

The most successful companies will probably not describe themselves simply as solar installers.

They will look more like integrated energy-service companies.

What Should Overseas Investors Watch Next?

For international investors, the most useful way to monitor China’s distributed-solar market is no longer simply to track annual PV installations.

Instead, watch the infrastructure around the assets.

China’s Distributed Solar Market Is Not Shrinking. It Is Becoming More Sophisticated.

It is tempting to interpret the slowdown in some provincial distributed-PV markets as the end of the sector’s growth story.

That would miss the bigger picture.

China is moving from a period in which solar capacity could grow faster than the market infrastructure around it, toward a period in which the value of each additional megawatt depends much more heavily on when the electricity is generated, where it is consumed, how it is traded and what environmental value can be attached to it.

That is why the next generation of distributed-energy companies will look different.

Virtual power plants will connect distributed resources to electricity markets. Green-power trading will transform renewable generation into a more sophisticated commercial product. Load aggregation will turn customer demand into an asset. Storage will provide flexibility. Multi-user green-power direct connection will create new industrial energy architectures.

And companies that can combine all of these capabilities may eventually become more valuable than companies that simply own the largest rooftop portfolio.
