M&E conducted two Data Quality Reviews under the Tanzania I Compact, the most recent of which was implemented in 2013. At the time, TANESCO had not reported any new customers connected to compact built lines. Given the more general concerns with TANESCO data quality issues, it may have been useful to conduct the DQR at a point at which outcomes are expected to manifest, and therefore there are relevant data points to verify. In addition, the independent evaluator could provide additional oversight to data collection and the DQR.
