Solar for Smaller Utilities: Why LADWP and RPU Homeowners Still Have Flexibility (For Now)

If you have been researching solar lately, you have probably heard a lot about NEM 3.0, also known as the Net Billing Tariff. For many homeowners in California served by large investor owned utilities, this shift fundamentally changed how solar pencils out financially and pushed battery storage from a nice option into something that feels almost required.

What often gets overlooked is an important nuance. Not every utility in California has adopted NEM 3. Smaller municipal utilities such as Los Angeles Department of Water and Power and Riverside Public Utilities operate under their own compensation rules. That means homeowners in these territories still have more flexibility when it comes to designing a solar system, and in many cases are not required to add a battery in order for solar to make sense.

Municipal utilities are owned and operated by the cities they serve. They do not answer to shareholders and they do not always move at the same pace as large investor owned utilities when it comes to policy changes. Because of this, programs like NEM 3 do not automatically apply to them. For homeowners, this creates a rare situation in today’s solar market where installing solar without storage can still be a rational and cost effective decision.

In LADWP and RPU territory, exporting excess solar energy back to the grid is still compensated in a way that allows traditional grid tied solar systems to work the way many people expect. Solar produces energy during the day, excess power flows to the grid, and credits help offset usage later. If your goal is to reduce your electric bill and you have consistent daytime energy usage, a solar only system can still accomplish that without forcing you into the added cost of storage.

This is especially relevant for homeowners who are budget conscious, want to keep upfront costs manageable, have predictable usage patterns, or prefer a simpler system with fewer components to maintain. Under these municipal utilities, solar can still deliver straightforward value without the added complexity of batteries.

That said, the fact that batteries are not required does not mean they are not valuable. Even in territories with lower rates, batteries provide benefits that go well beyond monthly bill savings. Storage offers protection during outages, greater control over when energy is used, and flexibility as homes become more electric with EVs, heat pumps, and modern appliances. Batteries also serve as a hedge against future policy changes, which are always a possibility as grids evolve and energy demand increases.

Municipal utilities like LADWP and RPU do tend to have lower and more stable rates compared to large investor owned utilities, which reduces the immediate pressure to install storage. However, lower rates do not eliminate long term risk. Infrastructure upgrades, wildfire mitigation, electrification, and regional grid constraints still apply. Over time, even municipal utilities will face pressure to modernize how energy flows on the grid and how exported power is valued.

Because of that, one of the smartest approaches available today is installing solar in a way that is battery ready. This means the system works perfectly on its own right now, but is designed so storage can be added later without major rework. It keeps upfront costs lower, preserves eligibility under current utility rules, avoids rushing into storage before it is needed, and allows homeowners to adapt as incentives, pricing, or personal energy needs change.

The biggest mistake homeowners make in today’s solar market is assuming everyone is playing by the same rules. Utility territory matters just as much as roof size, orientation, or equipment choice. If you are in LADWP or RPU territory, you still have something many Californians no longer do, and that is choice. Choice in system design, choice in timing, and choice in whether storage makes sense now or later.

At its core, solar has always been about reducing dependence on systems you do not control. Municipal utilities already offer an advantage with local governance and more stable rates. Solar takes that a step further by giving homeowners control over how energy is produced and used. Storage can extend that control even more, but it does not have to be an all or nothing decision on day one.

The key is having a plan that aligns with your home, your budget, and where energy is heading. When solar is designed thoughtfully, flexibility is built in, and homeowners stay ahead of changes instead of reacting to them later.
