Solar Microgrids and the Local Economy
What local economy does a microgrid create, beyond the connections it counts?
The question from practice
Decentralised solar is counted in capacity installed and connections made. Practice asks what the energy is used for. A microgrid that lights homes and a microgrid that runs a mill, a cold room, a pump and a repair shop cost the same and produce entirely different local economies. Two policy obstacles surface repeatedly: escalating benchmark costs, which make the economics hard to justify, and structures that cost more than the panels they hold.
Research objective
To establish what local economy a microgrid generates: productive-use loads, enterprises formed, value unlocked, returns to public investment and who benefits. Alongside this, to test prefabricated and low-cost mounting structures for cost reduction across six trial sites, including configurations combining microgrids with agrivoltaics.
What each partner brings
CTARA brings engineering rigour on structures, system design and costing, and a long record of rural technology alternatives. TriQuest brings the sites, the community institutions that will own and use the load, the enterprise pipeline and the state engagement.
TriQuest linkage
Configurations that build productive use into the design rather than hoping it follows.
Cost and performance evidence from farmer-condition trials, with productive-use outcomes rather than technical outputs alone.
Cost benchmarks and structure specifications that address the price-escalation justification, feeding the design of PM-KUSUM and successor decentralised solar programmes.
Academic and policy space
Energy-access scholarship is rich on tariffs, technology and financing, and thin on the local economy that follows the connection. That is where this study contributes, and it is the question a state energy department needs answered before it scales.
