Do I have grounds for a rent concession?

Hey y’all hope the summer is treating you well!

I’ve had an issue with my apt a couple of times now where the power has gone out ONLY to my unit (main breaker flipped somewhere in the building).

• First time: Power was out for a day. Called maintenance, they told me it was a Seattle City Light issue. Called SCL, they told me it was all fine on their end. Called maintenance again, finally they realized it was the breaker in the building just for my unit they had to go flip.
• Second time: Power was out for 4 days. Called maintenance and told them exactly the issue and how to fix it. No response for days. Called again, they told me it was an SCL issue. Finally on day 4 maintenance calls and tells me it was the main breaker again (literally what I told them when I called).
• Both times had to throw out my entire fridge/freezer contents 🙁
• Wasn’t doing anything crazy to trigger the issue, just living normally (microwave + stove at the same time???)

Obviously I’m pissed, and annoyed that this can happen at any moment. How can I approach this, and what do I have grounds to ask for here?
