Rooftop solar passes a new installed capacity milestone
Private installations continue to grow, reshaping demand patterns in ways the system operator is still modelling.
Installed rooftop capacity has passed a further milestone, driven mostly by commercial and industrial customers.
Effect on the grid
Distributed generation has flattened midday demand and sharpened the evening ramp, a pattern the system operator now plans around explicitly.
Industry submissions on the proposal closed earlier this month, and the volume of comment was unusually high. Trade associations, large energy users and two of the metros all filed responses, most of them supportive of the direction while critical of the timelines. Several submissions asked for a longer transition window, arguing that the compliance burden falls hardest on the smallest participants, who have the least capacity to absorb it.
The financial picture is more complicated than the headline figures suggest. Capital costs have fallen consistently over the last decade, but the cost of connecting to the grid has moved the other way, and in several provinces now represents a material share of total project cost. Developers have begun selecting sites for network availability first and resource quality second, a reversal of the logic that governed earlier rounds.
Registration gaps
A material share of installations remains unregistered, which limits visibility and complicates forecasting.
Employment effects are harder to measure than they are to claim. Construction phases generate significant short-term work that moves on when the site is complete, while operations and maintenance roles are fewer but permanent. The distinction matters for the communities involved, who have in several cases been presented with construction numbers as though they were lasting jobs.
Municipalities occupy an awkward position in the reform. They are simultaneously distributors, revenue collectors and, increasingly, customers of independent generators. The cross-subsidy that funds street lighting and reticulation maintenance is embedded in the electricity tariff, so any shift in who buys power from whom has consequences well beyond the electricity account.
Analysts caution that implementation, rather than intent, will determine how quickly households and businesses feel the difference. The next reporting period should offer the first hard evidence either way.
