Many homeowners dive into solar installations with grand expectations, only to find the realities of LADWP's NEM program a bit... nuanced. From understanding the true value of your solar credits to deciphering complex billing statements, it's easy to feel overwhelmed and possibly even shortchanged if you aren't fully informed.
This post will unpack five often-overlooked facts about LADWP's Net Energy Metering program. By understanding these key aspects, you can make informed decisions, optimize your solar investment, and avoid potential surprises down the road. We'll cover everything from the true value of exported energy to the often-misunderstood true-up process.
In this guide, we'll uncover the less talked about aspects of LADWP's Net Energy Metering (NEM) program, shedding light on topics like energy credit values, true-up periods, interconnection agreements, eligible system sizes, and crucial application deadlines. Getting a grip on these details can dramatically impact your solar savings and ensure a smoother, more beneficial experience with your solar panels. Let's dive in and demystify the world of LADWP NEM!
Fact #1: Understanding the "True-Up" Period
The "true-up" period is a critical component of LADWP's NEM program, yet it's frequently misunderstood. I remember when my neighbor installed solar, he was ecstatic for the first few months, boasting about his near-zero electricity bills. However, when his true-up bill arrived, he was shocked to see a significant charge! Turns out, he didn't fully grasp how the annual reconciliation worked.
The true-up is essentially LADWP settling the score for the entire year. During the year, you're credited for excess energy you send back to the grid. These credits offset the energy you consume from LADWP when your solar panels aren't producing enough (like at night). However, these credits aren't valued at the full retail rate. At the end of your 12-month billing cycle, LADWP calculates whether you've used more energy than you produced (resulting in a bill) or produced more than you used (resulting in a small credit, often at a lower rate than what you pay for electricity). This annual settlement is the true-up.
Why is this important? Because understanding the true-up prevents surprises. If you consistently use more energy than you generate, you'll owe LADWP at the end of the year. This could be due to increased energy consumption (like adding an electric vehicle charger or running your AC more) or a solar system that's undersized for your needs. Conversely, if you consistently overproduce, your credits will be minimal. Careful planning and energy management are key to maximizing your solar savings and avoiding a hefty true-up bill.
Fact #2: Energy Credit Values Are Not Always Equal to Retail Rates
One of the biggest misconceptions about LADWP's NEM is that you'll receive full retail price for every kilowatt-hour (k Wh) of excess energy your solar panels send back to the grid. This isn't always the case. Understanding how LADWP values your excess energy is crucial for accurately calculating your solar savings.
While LADWP does credit you for excess energy, the rate they offer isn't the same rate you pay for electricity. The export rate, also known as the "avoided cost" rate, is typically lower than the retail rate. This is because LADWP argues that they're avoiding the cost of generating or purchasing that energy themselves, and they value it accordingly.
The exact avoided cost rate can fluctuate depending on various factors, including the time of year and the current energy market. It's essential to understand this discrepancy when estimating your solar payback period. For example, if you think you're getting 30 cents per k Wh for your excess energy when you're actually getting 15 cents, your payback period will be significantly longer than anticipated. Check with LADWP or your solar installer for the most up-to-date avoided cost rate information to ensure accurate calculations.
Fact #3: Interconnection Agreement Nuances
The interconnection agreement is the contract between you and LADWP that allows you to connect your solar system to the grid. It's a crucial document that outlines the terms and conditions of your participation in the NEM program. However, many homeowners skim over this agreement without fully understanding its implications.
Within the interconnection agreement are details about system size limits, liability, insurance requirements, and the process for resolving disputes. One often-overlooked aspect is the requirement for system maintenance and safety inspections. LADWP may require periodic inspections to ensure your system is operating safely and according to code. Failing to comply with these requirements could result in penalties or even disconnection from the grid.
Additionally, the interconnection agreement may contain clauses that address changes to LADWP's NEM program in the future. These clauses could allow LADWP to modify the terms of your agreement, potentially impacting your solar savings. It's crucial to carefully review the interconnection agreement with a qualified legal professional or solar expert to fully understand your rights and obligations. Don't assume you're automatically grandfathered into the existing NEM program forever; the agreement governs the relationship.
Fact #4: System Size Matters More Than You Think
Many homeowners assume they can install as many solar panels as they want. However, LADWP has specific rules regarding the size of your solar system relative to your historical energy consumption. Exceeding these limits can disqualify you from NEM or reduce the benefits you receive.
LADWP typically limits the size of your solar system to no more than 100% of your historical energy usage over the past 12 months. This is to prevent you from becoming a large-scale energy producer and potentially disrupting the grid. If you install a system that's significantly larger than your energy needs, LADWP may not credit you for all of the excess energy you generate, or they may offer a significantly lower rate.
Before installing solar, it's essential to carefully analyze your energy consumption patterns and choose a system size that aligns with your needs. Consider future energy demands, such as adding an electric vehicle or expanding your home, but avoid oversizing your system solely for the purpose of generating excess energy. Working with a qualified solar installer who understands LADWP's system size limitations is crucial for maximizing your NEM benefits.
Fact #5: Application Deadlines and Program Changes
LADWP's NEM program isn't static; it's subject to change based on regulations and policy decisions. Staying informed about application deadlines and potential program modifications is crucial for ensuring you qualify for the best possible terms.
Like many solar incentive programs, LADWP's NEM program could evolve over time. Changes could include adjustments to the avoided cost rate, modifications to system size limits, or even the introduction of new fees or charges. These changes could significantly impact the economics of your solar investment. Furthermore, NEM applications often have deadlines, and missing those deadlines can delay your project or even disqualify you from the program.
To stay ahead of the curve, subscribe to LADWP's updates, follow industry news, and work with a reputable solar installer who is well-versed in the latest program changes. Staying informed will help you navigate the complexities of LADWP's NEM program and maximize your solar savings.
Digging Deeper: Understanding Demand Charges and NEM
For larger commercial solar installations, demand charges can significantly impact the overall cost savings under LADWP's NEM program. Demand charges are based on the peak amount of electricity your business uses at any given time during the billing cycle, regardless of the total amount of energy consumed. Even with solar panels generating electricity, if your business has a high peak demand, you could still incur substantial demand charges.
Under NEM, solar generation can help reduce your overall energy consumption, but it might not directly address your peak demand. For example, if your business's peak demand occurs in the evening when the sun isn't shining, your solar panels won't be able to offset those demand charges. To effectively reduce demand charges with solar, businesses need to implement strategies such as energy storage systems (like batteries) or demand response programs.
These strategies allow businesses to store excess solar energy generated during the day and use it to offset peak demand in the evening, or to reduce their electricity consumption during periods of high demand. Understanding how demand charges work and how to mitigate them with solar and other technologies is crucial for maximizing the economic benefits of solar for commercial customers under LADWP's NEM program.

Understanding Time-of-Use (TOU) Rates and NEM
LADWP offers Time-of-Use (TOU) rates, which vary the price of electricity depending on the time of day and the season. Combining solar with TOU rates can be a powerful strategy for maximizing your NEM benefits, but it requires careful planning. The key is to shift your energy consumption to off-peak hours when electricity is cheaper and to generate as much solar energy as possible during peak hours when electricity is more expensive.
For example, you can schedule your appliances, such as dishwashers and washing machines, to run during off-peak hours. You can also use smart thermostats to pre-cool your home during off-peak hours so you can use less energy during peak hours. By shifting your energy consumption to off-peak hours, you can reduce your overall electricity costs and increase the value of your NEM credits.
However, it's essential to carefully analyze your energy consumption patterns and choose a TOU plan that aligns with your solar generation profile. Some TOU plans may have higher peak rates than others, so it's crucial to choose a plan that maximizes your savings. Working with a qualified solar installer who understands LADWP's TOU rates can help you make the right choice and optimize your NEM benefits.

What If My Solar System Produces More Energy Than I Use?
If your solar system produces more energy than you use over the course of a year, LADWP will credit you for the excess energy at the avoided cost rate. However, as mentioned earlier, this rate is typically lower than the retail rate you pay for electricity. Therefore, it's generally not advisable to oversize your system solely for the purpose of generating excess energy.
Instead, it's better to size your system to meet your historical energy consumption needs, taking into account any future energy demands. If you do end up producing excess energy, you can use it to offset your electricity costs during peak hours or to power electric vehicles or other energy-intensive appliances.
In some cases, LADWP may offer net surplus compensation for excess energy generated by larger commercial solar systems. However, the compensation rate is typically very low, so it's generally not a significant source of revenue. The primary goal of installing solar should be to reduce your electricity costs and improve your energy independence, not to generate excess energy for profit.
