Operational Capacity & Expertise
* Includes sites built for E.On, Engie, SteamaCo, and other clients.** PH is currently actively building its first batch of sites with GMG funding in Kenya so this number is rising
PowerGen’s executional expertise is highly unique in the market – as a result, several other developers have relied on PowerGen to build their micro-grids
The Africa Enterprise Challenge Fund awarded PowerGen a
grant and concessional debt in 2015.
The Energy and Environmental Partnershipawarded PowerGen a grant
for microgrids in 2015.
The Kenya Climate Innovation Centre
awarded PowerGen a grant in 2014.
The Challenge Cup named PowerGen the winner for
Kenya in 2015, and PowerGenwas invited to speak at the
White House about its work with microgrids.
The Sankalp Forumnamed PowerGenrunner-up in 2015.
The Global Entrepreneurship
Summit 2015 invited PowerGen to exhibit to
President Obama’s Nairobi delegation in
2015.

Where does energy storage fit?
19
Energy storage allows systems to shift supply to match demand.
Energy StorageIn residential contexts, peak load on a minigrid often occurs in the evening when customers return home from work. Because solar PV panels only generate during the day, batteries or generators are needed to serve this demand.
Energy storage can strengthen the grid in many ways.
Various types of energy services can provide valuable services to the grid.
Electrochemical
• Battery
• Flow Batteries
• Hydrogen
Mechanical
• Flywheels
• Compressed air
• Pumped Hydro
Electrical Thermal
• Capacitors
• Magnets
• Hot water storage
• Thermal fluid storage

3. Paths to Africa’s Distributed Energy Future
A Path Forward
1. Policy
2. Tools
3. Dialog
Policy: Binary perceptions of electrification are damaging to innovative problem-solving
30
On-Grid Off-Grid
Policy: Energy leadership requires nuanced approaches to energy policy.
31
Off-GridOn-Grid
Future Power System
Policy: Leap-frogging to a distributed energy systems requires smart policy decisions now.
32
Off-GridOn-Grid Smart Policy Space
1. Incentives for DER providers that align with the country’s goals for electrification. Clear $/connection subsidy on par with grid extension subsidies.
2. Framework for DER interconnection (especially energy storage) that recognizes the value they provide to the grid.
3. Efficient disbursement mechanisms for DER providers.
Tools: Data rich systems enable control and analysis at an unprecedented level of granularity.
33
Smart power systems
Smart appliances & devices
Tools: Blockchain as a means of aggregating small-scale storage.
Blockchain technology provides a means of aggregating energy storage in a highly efficient way.
“Smart contracts” automate multiple important features:
• Storage dispatch according to market behavior
• Incentive disbursement when milestones are achieved
• Coordinated control over many small-scale energy storage units across an entire network
34
Dialog: Engage with on-the-ground private sector players to formulate policy.

PowerGen database captures demographic information and
GIS data from various sources to get a high-level
understanding of each site and plan surveying trips
Experienced Site Surveyors gather permits and licenses for
each district, town and site and then conduct full survey of
location with community leadership
Database and AnalyticsSites are narrowed down through a systematic scoring
methodology that analyzes 250+ data points about the
demand, logistics, social impact and grid connection
Customer team conducts application process and gathers
40+ data point per customer to inform connectivity,
reticulation, distribution, and tariffs
While full microgrid infrastructure is installed, the customer
team works with customers to sign into system, make first
payment, and try electricity
