We need to write a professional original news article, 300-500 words, SEO optimized, human-like, no AI style, clear structure, with analysis. Title: Battery storage mandated for power auctions, igniting optimism for clean energy. Summary: includes a link and Dawn. The structure: Introduction, Key Developments, Industry Analysis, Future Outlook, Conclusion. Return only the SEO-optimized content. So output just the article with headings? Probably include headings for each section. Must be 300-500 words. Let's aim ~380 words. Include SEO keywords: battery storage, power auctions, clean energy, renewable energy, grid reliability, etc. Provide analysis. Avoid AI style (i.e., not too robotic). Write like a journalist.

We need to include the summary line? The prompt gave a summary with a link and Dawn. Should we include that? Likely we need to include the summary as part of the article? It says "Summary: Battery storage made mandatory for power auctions  Dawn" So we need to include that summary maybe as a lead? Usually news article has headline, summary (lead), then body. So we should output the title, then the summary (as a paragraph), then sections.

We must output only final result, no extra commentary. Ensure word count 300-500. Let's craft ~380 words.

Title line: Battery storage mandated for power auctions, igniting optimism for clean energy

Then summary line: Battery storage made mandatory for power auctions  Dawn

Draft:

Battery storage mandated for power auctions, igniting optimism for clean energy

Battery storage made mandatory for power auctions  Dawn
