We need an energy access revolution: A new approach to innovation can help – pv magazine International

The energy sector is currently undergoing the greatest revolution since the Coal Age gave way to the Oil Age. New technologies are radically transforming the economics of delivering power. Over the past decade, the cost of delivering power to people living off-grid through standalone solar and storage mini grids has decreased by up to 85%.

The World Bank believes mini grids will be the cheapest way to bring power to half a billion people, most of whom live in rural communities and would be considered low-income on any global scale. But although mini grids are already cheaper than the main grid in many areas, they are still too expensive to profitably connect these potential customers.

There is an opportunity for a new revolution in energy access. As governments consider ways to rebuild the global economy, investing in mini grids is critical to driving equitable economic growth and a climate positive future. To achieve this seismic shift, we need to unleash innovation.

Private mini grid companies are working to incrementally innovate the business model. However, it’s not happening fast enough. To speed up innovation and unlock revolutionary change, the Rockefeller Foundation seeded the Mini-Grid Innovation Lab.

A new approach to innovation

The Mini-Grid Innovation Lab is pioneering a new approach to innovation in energy access. Launched in 2018, the lab identifies the most promising innovations by field testing prototype innovations in an iterative process and evaluating which have the greatest impact on the business model. The lab is funded with public money and donor funds, and makes its findings public, sharing innovations directly with companies and governments to spread the knowledge.

The lab consists of 25 private mini grid companies, working in collaboration together. It accelerates the speed of innovation by working through these 25 private actors, combining the strengths of public and private sector innovation.

Every quarter, the lab convenes these 25 private mini grid companies to identify and design innovations to test within their own businesses and among their own customers. It then funds these private sector companies to test the innovations, on the condition they share the resulting data with the lab to distribute with the entire private sector.

The lab aggregates the data across all companies and analyses it to determine the impact on the business model. It makes its findings publicly available, for free, to the entire sector, and continually repeats this process of idea gathering, testing, and sharing to rapidly accelerate sector innovation.

Private sector and public sector approaches to innovation

In a simple model, innovation can emerge in two ways:

Each model involves trade-offs.

Private sector companies are often the best engines of short-term innovation, because the incentive to survive is highly motivating. These companies are also the best judge of the most relevant solutions given they’re closest to the problems. However, we can’t rely on private companies to scale innovation to other companies in the sector. It’s not in their market interest to do so. In fact, it’s in their interest to stop the spread of innovation.

Apple’s seven-year pursuit of Samsung for patent violations was only settled last year for several hundred million dollars. Every smart phone is slightly more expensive and slightly lower quality than it could be, because each private sector actor is jealously guarding its competitive advantage.

An SSIR article last year raised this issue with private sector innovation in Pay-As-You-Go (PAYG) solar, noting “Mutual awareness is low, and meaningful coordination is even more uncommon. This applies to collaboration…between companies and organizations working within the same sector.”

Public sector innovation is, by definition, public. Unlike their private counterparts, public actors make their innovations widely available – they share all information for the market to act on. Public actors can also be more patient and direct large amounts of risk capital towards innovation without a return expectation.

But public actors are typically further from the problem and are also inherently less incentivized to drive toward a ‘product’ or solution that will reach the hands of a customer in need. None of the government agencies working on the technologies behind the iPhone integrated them into a commercial smartphone. Public innovation is shared but is slow and disconnected from end users’ real challenges.

The lab’s combined approach to innovation in action

The traditional paradigm of innovation presents a choice. Fast but proprietary and therefore siloed. Or, shared but slow and isolated from the end-user. The lab is pioneering a new model that captures the best of both models. It provides donor funding to private sector actors to test agreed innovations on the condition that they share the results back with all their competitors.

Through this approach, the lab combines the strengths of private sector innovation – speed and relevant knowledge of the problem – and public sector innovation – patient funding and open dissemination of knowledge. To make this real, it’s helpful to consider an example.

Grain milling is one of the most important productive uses of energy for people living off-grid in rural Africa. Maize is the most commonly produced cereal in sub-Saharan Africa, and grain millers use that maize to produce flour, a key ingredient in staple foods for rural communities.

Powering grain mills with solar mini grids would transform the off-grid energy sector, delivering clean, reliable, 24/7 power to rural businesses. However, diesel mills dominate the rural off-grid market, because no solar-powered electric mill exists that can match them on both cost and performance.

To solve this, the lab brought together a coalition of private sector and public sector partners to iterate on the off-grid electric mill until it could match its diesel rival. It ran the following process:

The lab is now applying this innovation approach to other promising tools to drive down capital expenditure costs and drive-up revenues. It is conducting field trials deploying smart inverters, reducing electricity tariffs, bulk procuring hardware, and bundling internet with power across Tanzania, Kenya, Nigeria, and Zambia.

The lab is also partnering with advocacy experts, technology companies, financiers, and on-the-ground implementing partners to scale those innovations proven successful. With Rockefeller’s support, it will share its findings with key governments, donors, and investors needed to accelerate this scale.

The lab is field testing 10 innovations that together could make mini grids commercially viable by reducing capex per connection from US$1,000 to $500 and increasing average revenue per user (ARPU) from $5 to $17 per month

If these trials are successfully scaled, this new approach will have dramatically accelerated progress towards universal electrification in Africa. It will have sparked a new revolution in energy access, giving poor, rural communities across the continent access to affordable and reliable power for the first time.

Looking beyond energy access

We believe the lab represents an interesting new model of innovation that combines the strengths of both private and public sector innovation. This approach could have a similar impact in other sectors where advancing public good requires private sector innovation.

Donors could support innovation labs in smallholder farming, microfinance, and transport. Combining the speed and relevance of private sector innovation with the broad dissemination and funding of public sector innovation offers a way to ‘innovate on innovation’.
