PSS Vs. PSPS: What's The Difference?

Are you scratching your head over PSS vs. PSPS and what it all means? Don't worry, guys, you're not alone! The energy sector can throw some serious jargon our way, but understanding these terms is crucial, especially if you live in an area prone to wildfires or are just curious about how your electricity gets to you. We're going to break down what PSS and PSPS are, how they differ, and why it matters to you. So, let's dive in and make sense of it all!

What is a Public Safety Power Shutoff (PSPS)?

Let's start with the big one: Public Safety Power Shutoffs (PSPS). These are events where a utility company, like your local power provider, intentionally turns off the electricity in certain areas to reduce the risk of wildfires. This is a proactive measure, meaning it's done before a fire starts, based on weather forecasts and other factors that indicate a high risk of fire. Think of it as a preemptive strike against Mother Nature's fiery temper.

The main goal of a PSPS is to prevent electrical equipment from sparking and igniting a wildfire. High winds, dry vegetation, and low humidity are the perfect recipe for a fire, and if a power line is damaged or comes into contact with something, it could be the source of ignition. By shutting off the power, the utility hopes to eliminate that risk and keep everyone safe. It's a tough decision, because it means that everyone relying on the electrical grid is impacted. It impacts homes, businesses, schools, and emergency services. But the potential cost of not doing it—a devastating wildfire—is far greater.

When a PSPS is declared, the utility company will usually give you as much notice as possible. However, depending on how quickly the weather conditions are changing, it may only be a few hours before the power is turned off. They will also notify you when the power is expected to be shut off and when they anticipate restoring it. The length of a PSPS event can vary, from a few hours to several days, depending on the severity of the weather and the time it takes for utility crews to inspect and repair the lines after the weather passes. During a PSPS, you will want to have a plan in place. This could include having a backup power source, like a generator, stocking up on supplies like food and water, and keeping your devices charged. It’s also important to know where to get information updates from your utility company and any emergency service providers.

What is a Power Source Selector (PSS)?

Now, let's talk about Power Source Selectors (PSS). This is different from a PSPS, as PSS isn’t directly related to wildfire prevention. Instead, a PSS is a device that allows you to switch between different power sources. It can be a manual or an automatic device. For example, if you have a generator, a PSS lets you safely and easily switch your home's electricity from the grid to the generator. Think of it as a switch that reroutes your electricity supply.

PSS devices are commonly used in situations where you want to have backup power, whether it’s because of potential power outages due to storms, equipment failures, or, as we've been focusing on, PSPS events. The primary benefit is the ability to maintain power to critical appliances and devices. It's critical during a PSPS event, and also useful during general power outages. This could include things like your refrigerator, medical devices, or heating and cooling systems. It ensures that these essential services can keep running, even when the grid is down.

Using a PSS is pretty straightforward, though you should consult with a qualified electrician for proper installation. It typically involves connecting the PSS to your home’s electrical panel and then connecting your backup power source, such as a generator. When the power goes out, you can manually or automatically switch the PSS to your backup power source. The key is to do this safely, to avoid back-feeding electricity into the grid, which can be extremely dangerous for utility workers and could also damage the electrical equipment.

PSPS vs. PSS: What's the Difference?

So, here’s the million-dollar question: What is the difference between PSPS and PSS? It’s simple, but the distinction is crucial.

• PSPS (Public Safety Power Shutoff) is a planned event by the utility company to proactively shut off power in high-risk areas to prevent wildfires. It’s about when your power is on or off.
• PSS (Power Source Selector) is a device that allows you to switch between power sources. It's all about how your power is supplied.

Think of it this way: PSPS is the reason your power might be off, while PSS is a solution to have power during a PSPS or other outages. PSPS is reactive (in a preventative way), and PSS is a proactive tool to manage the impact of the PSPS or other power disruptions. They are related, but they function very differently.

Why Should You Care?

Why is it important to know the difference between PSS and PSPS? Here's the lowdown:

• If you live in a wildfire-prone area: Understanding PSPS will help you prepare and stay safe. Knowing when and why the power is being shut off is crucial, and having a plan for outages is even more critical.
• If you rely on electricity for essential needs: Medical equipment, refrigeration, and other necessities are the main focus of the PSS equipment and what it can supply. A PSS can be a lifesaver during a PSPS or other unplanned outages.
• For general preparedness: Everyone should have a basic emergency preparedness plan. Knowing how to respond to power outages, having backup power sources, and understanding the potential causes of outages (like PSPS) is just smart.

Essentially, it’s all about being informed, being prepared, and being able to make decisions that keep you and your family safe and comfortable, especially during extreme weather events or when your power supply might be disrupted.

How to Prepare for PSPS Events

Being prepared for a PSPS event is a must, especially if you live in an area that's frequently impacted. Here are some steps to help you get ready:

1. Sign up for alerts: Make sure you're signed up for alerts from your utility company. They will send you notifications about planned PSPS events, including the areas affected, the estimated start and end times, and any updates. You may need to visit your utility’s website to opt in for the alert system.
2. Create an emergency kit: This kit should include essentials like non-perishable food, water, flashlights, a first-aid kit, medications, and any other supplies you might need for several days. Make sure to include a battery-powered or hand-crank radio to stay informed about the situation.
3. Identify critical devices: Make a list of the appliances and devices you rely on, especially those that are essential for health and safety. Consider how you will keep these devices running during a PSPS. If any of these are medical devices, you may want to consult with your doctor or care provider about how to prepare.
4. Consider backup power options: If you rely on electricity for essential needs, you should explore backup power options. This might include a portable generator or a battery backup system. Remember that generators should be operated safely and outside of your home.
5. Develop a communication plan: Create a plan for communicating with family and friends during a PSPS. Decide how you will stay in touch, where you will meet if you're separated, and who your emergency contacts are. Keep a list of important phone numbers, and have a backup method of communication, like a satellite phone or a two-way radio, if possible.
6. Keep your car's gas tank full: Gas stations rely on electricity to operate their pumps. Keeping your car's gas tank full can help ensure you have transportation if needed.
7. Keep your mobile devices charged: Make sure your mobile devices are fully charged. Also, consider investing in a portable power bank or car charger to keep your devices charged during a PSPS.
8. Understand your utility’s policies: Review your utility company's policies regarding PSPS events. They should have information about what areas are impacted, how they make decisions, and what resources they provide to customers during these events. Understanding these policies can help you anticipate the timing of an event.

By taking these steps, you can be better prepared for a PSPS event, making you more self-sufficient and less vulnerable to the disruptions caused by these planned outages. Being prepared is not just about surviving a PSPS, it's about staying safe, comfortable, and informed.

Choosing the Right PSS for Your Needs

If you've decided that a Power Source Selector (PSS) is right for you, the next step is choosing the right one for your needs. Here are some things to consider when selecting a PSS:

1. Assess Your Needs: Think about what you want to power during an outage. List all the essential appliances and devices. This helps determine the size of PSS you need. You'll need to understand the wattage requirements of the devices. Include any critical medical devices or other items essential for comfort or safety. This will give you a good starting point.
2. Determine the Electrical Load: Add up the total wattage required by the devices you want to power. This will determine the capacity of the PSS and generator that you need. Ensure the PSS has enough capacity to handle the load. Underestimating your needs can leave critical appliances without power.
3. Manual vs. Automatic: A manual PSS requires you to switch the power source manually. An automatic PSS senses the power outage and switches to the backup source automatically. The automatic models are more convenient. But they cost more. You need to decide if the convenience of an automatic is worth the extra investment.
4. Safety Features: Look for a PSS with safety features like overcurrent protection and reverse polarity protection. These features can help prevent electrical hazards. Make sure the unit is properly grounded and has all the necessary safety certifications.
5. Ease of Installation: Consider the ease of installation. Some PSS units are designed for DIY installation. However, you should always consult with a qualified electrician.
