Viable Productive Uses of Electricity Programs Remain Elusive:
A practitioner's field-based recommendations for overcoming challenges
By Brian Gurr and Allison Archambault
Productive uses of electricity such as machines that can perform agricultural processing are core to unlocking the economic development potential of community microgrids around the world. While energy access funders are now interested in this concept, the reality remains that truly transformative ‘plug and play’ applications remain elusive. Read the full paper here.
Medium Voltage Distribution Considerations in Clean Energy Community-Scale Microgrids
Community-scale clean energy microgrids have characteristics that make them different from large-scale infrastructure and even from diesel-powered microgrids. While there is little written on this topic, we posit here that choosing an appropriate medium voltage level is important for stable and efficient microgrid operation.

Productive Use of Energy in African Micro-Grids: Technical and business considerations
By Samuel Booth, Xiangkun Li, Ian Baring-Gould, Diana Kollanyi, Abishek Bharadwaj, and Peter Weston from National Renewable Energy Laboratory and Energy 4 Impact
Small industry and business demand for electricity are important to enhancing the economic and social development impacts of micro-grids and rural electrification. The challenge to these productive uses of electricity is the struggle to reach critical revenue needed for financial viability on grids with typically low revenue residential customers. This paper explores several use cases in East Africa.
This paper functions as a resource for micro-grid operators, entrepreneurs, governments and NGO's to design productive use programs for successful micro-grid development in emerging economies. Read the full paper here.
