Net metering reforms are changing what a smart meter has to do.

Regulators across Asia are speeding up bidirectional metering and rewriting settlement rules for rooftop solar, and the meter now has to keep up with tariff logic, not just consumption.

For most of its life, the smart meter's job has been simple: count electricity flowing one way, from the grid to the customer. Three regulatory moves across Asia this summer show that job description is changing fast, and not gently. As rooftop solar spreads, meters are being asked to settle two-way flows, apply time-limited credits, and enforce capacity tiers, all in real time and all correctly, or the programme behind them stalls.

The Philippines: speeding up the queue

The Philippines' Energy Regulatory Commission has proposed cutting the interconnection timeline for net-metering applications from 20 working days to 10, with deemed approval if a utility fails to install a bidirectional meter on time. That single clause turns the meter into a compliance deadline, not just a device. Miss the install window and the customer is approved by default, whether the hardware is on the wall or not.

The same draft removes the 1 MW cap on distributed energy resources and allows multi-site crediting, while the ERC reviews the cost structure of bidirectional meters to make them more affordable. Taken together, this is a regulator trying to widen the door for solar while pushing the metering function to absorb the operational risk of doing so quickly.

Pakistan: when the backlog is the meter

Pakistan's Power Division has ordered distribution companies and the Pakistan Information Technology Company to urgently clear a backlog of net-metering applications. The cases in question are specific: consumers who paid demand notices, secured licences, had meters replaced or reprogrammed, and executed connection orders before a 9 February 2026 cutoff, but are still stuck. The instruction to verify documentary proof of payment tells its own story. The bottleneck is not solar installation, it is metering paperwork catching up with metering hardware that has already changed.

That gap between physical meter reprogramming and administrative sign-off is a familiar failure mode in fast-moving net metering markets. The meter can be technically ready long before the billing and settlement chain around it is.

Malaysia: granular by design

Malaysia's Suruhanjaya Tenaga has gone the other direction, publishing detailed guidelines up front rather than reacting to a backlog. The NEM Rakyat and NEM GoMEn schemes set clear capacity tiers and crediting rules that any bidirectional meter and its billing system now need to enforce correctly.

None of this is exotic policy. But every line item is a rule a meter and its data management system must apply without error, for years, across a growing base of residential solar customers. A crediting mistake at scale is not a customer service issue, it is a regulatory exposure.

The common thread

Three different regulators, three different tools: speeding up approvals, clearing a backlog, and publishing granular tariff design. What they share is a quiet assumption that the metering layer can absorb complexity that used to sit in policy documents. Capacity tiers, carryforward periods, crediting ratios and sunset dates are no longer things a tariff team manages in a spreadsheet once a year. They are logic that has to live in the meter data management system, applied consistently to every account, every billing cycle.

For AMI programmes built primarily for one-way consumption billing, that is a real gap to close. Bidirectional measurement is the easy part. Encoding time-limited credit rules, multi-site aggregation and capacity-tier enforcement into billing logic that regulators can audit is the harder one, and it is the part that determines whether a net metering reform actually delivers the interconnection speed and cost outcomes its regulator promised.
