Portugal will generate one hundred fifteen percent of its annual electricity from tidal lagoons by the year 2044.

Not enough quality evidence to judge

Why this isn't a yes or no

There isn't yet enough high-quality evidence to settle this.

What we can confirm

There is no evidence that Portugal has any official plan, projection, or credible study indicating it will generate 115% of its annual electricity from tidal lagoons by 2044; current literature treats tidal lagoons as an emerging or niche technology, and no country is projected to rely on them for all (let alone more than all) of its electricity demand.
