Here's what the three menus are and why Regular/Premium can show as unavailable.

**The difference between the menus**

All three menus charge your car exactly the same way — the only differences are the renewable-energy share (environmental value) and the price. Charging speed/output is identical no matter which menu you pick (/sources/en/runbooks/charging-use.md:234).

- **Premium (100% renewable)** — Charging done with 100% renewable electricity. PowerX uses "additionality" renewable power from newly developed and operating solar plants (via partner companies), with any shortfall covered by non-fossil certificates that meet RE100 standards. It has the highest environmental value.
- **Regular (70% renewable)** — Made up of about 70% renewable power (partly from PowerX's own renewable sources) and 30% regular grid electricity. It balances cost with environmental consideration.
- **Economy** — Uses the electricity from the utility company that the host facility where the charger is installed is contracted with, as-is. The renewable share depends on that site's contract, and it's the most economical option.

(Official description: /sources/ja/public-help/articles/52372827146777.md:20-26, updated 2026-07-22. For reference, general-member pay-as-you-go rates are 65/70/75 yen per kWh for Economy/Regular/Premium — /sources/en/runbooks/billing.md:46.)

**Why everything except Economy is "out of stock" at your site**

Premium and Regular are composed mainly of solar-derived power. When the weather is bad or sunlight is low, solar generation efficiency drops, and those menus can become unselectable — which is why they may appear as "out of stock" while Economy remains available (/sources/en/runbooks/escalation.md:55). If your usual site is affected frequently or for extended periods, it may simply be a location where the solar supply is more weather-sensitive.

**When will it be resolved?**

There's no fixed restoration date I can quote — availability depends on solar generation conditions, so the menus typically become selectable again when sunlight conditions improve (e.g., on clearer days). I don't have a published timeline for a permanent fix at specific sites, and I don't want to guess.

**What I'd suggest in the meantime**

- Please use an available menu (Economy) — your charging speed and the charging experience are exactly the same; you just won't get the higher renewable share on that session.
- If you specifically want the renewable menus, try again on days with better weather/sunlight, or check whether another nearby site has them available.

If the unavailability persists over a long period regardless of weather, let me know the site name and I can pass it on to the relevant team as feedback for investigation.

**What actually differs between the three menus**

The only real difference is the renewable-energy share (i.e. the environmental value) of the electricity — and the price. Charging output/speed is identical on all three menus, and it also does not change by membership type.

- **Premium — 100% renewable:** uses "additionality" renewable power from solar plants newly developed and brought online through PowerX partner companies, with the shortfall covered by non-fossil certificates meeting RE100 criteria. Highest environmental value; effectively zero CO₂ for the electricity you charge.
- **Regular — ~70% renewable:** partly PowerX's own renewable generation, blended 70% renewable / 30% general grid power. Designed to balance cost and environmental consideration.
- **Economy — follows the host facility's contract:** uses the electricity the installation site's own utility contract supplies, so the renewable share varies from site to site. The simplest and cheapest option.

Reference: /sources/ja/public-help/articles/52372827146777.md:20-25 (official Help Center article, updated 2026-07-22); speed equivalence at /sources/en/runbooks/charging-use.md:234 and /sources/en/runbooks/compatibility.md:139. For scale, 50 kWh on Regular leaves 15 kWh grid-derived ≈ 6.345 kg CO₂ (0.423 kg-CO₂/kWh, FY2023 Agency for Natural Resources and Resources figure), versus 0 kg on Premium — /sources/ja/public-help/articles/24483463716505.md:29-32.

Indicative per-kWh rates: general membership 65 yen (Economy) / 70 (Regular) / 75 (Premium); PowerX First members get roughly ¥20/kWh off, from 45/50/55 yen — /sources/en/runbooks/charging-use.md:105, /sources/en/runbooks/membership.md:186.

**Why only Economy is selectable at your usual site**

Premium and Regular are built mainly from solar-derived power, so when weather is poor or sunlight is insufficient, generation efficiency drops and those menus can become unselectable ("out of stock") at a given location. Economy draws the site's ordinary contracted electricity, so it stays available regardless of sunlight. This is documented guidance for exactly this complaint at /sources/en/runbooks/escalation.md:55 (CS-117) — and the same text notes that menu choice never changes charging speed, so using Economy costs you nothing in charge time.

**When it will be resolved**

I can't give you a date. The available sources explain the cause but contain no restoration timeline, no site-level availability data, and no commitment about how long Regular/Premium remain unavailable at a specific location — so any date I gave would be invented. What the guidance does say is simply to use whichever menu is available for that reservation.

Two practical notes:
- Because Premium/Regular availability tracks solar output, they are more likely to be selectable in bright daytime conditions than in the evening or on overcast/rainy days.
- Economy is not automatically "non-green": its renewable share depends on the host facility's own electricity contract, so at some sites it may already carry a meaningful renewable portion.

If you tell me the site name, I can note the pattern (Regular/Premium persistently unavailable, not just on cloudy days) as feedback — but I can't confirm that any change will be made or when, and I won't say an action was taken unless it's confirmed.

充電メニュー3種類の違いは「使う電気の再生可能エネルギー比率（環境価値）」と単価だけで、充電の速さ（出力）はどのメニューでも共通です（/sources/ja/runbooks/charging-use.md:234、/sources/ja/runbooks/compatibility.md:139）。

メニューの概要（/sources/ja/public-help/articles/52372827146777.md:20-25）
- Premium（再エネ100%）: パートナー企業を通じて新たに開発・稼働させた太陽光発電所の「追加性のある再エネ電源」を一部に使い、不足分はRE100基準に準じた非化石証書で補う、環境価値が最も高いメニュー。
- Regular（再エネ70%）: PowerXの自社再エネ電源を一部に使い、再エネ70%・一般電力30%で構成。コストと環境配慮のバランス型。
- Economy（設置先の電力契約に準ずる）: 設置先施設が契約している電力会社の電力をそのまま使う、最も経済的なメニュー。再エネ比率は設置先の契約内容により異なります。

料金は従量課金で、一般会員は1kWhあたりEconomy 65円／Regular 70円／Premium 75円、PowerX First会員は同45円／50円／55円〜が目安です（/sources/ja/runbooks/charging-use.md:105、/sources/ja/runbooks/membership.md:186）。拠点やキャンペーンにより適用が異なる場合があり、例えばAudi HUBはFirst価格の対象外です（/sources/ja/runbooks/stations.md:174）。環境価値の違いとしては、Premiumで充電した場合の走行時CO2排出量は実質ゼロ、Regularで50kWh充電した場合は15kWh分が系統電力由来となり約6.345kg-CO2と算出されています（/sources/ja/public-help/articles/24483463716505.md:29-32）。

エコノミー以外が「在庫切れ」になる理由
Regular／PremiumはPowerX側で確保した再エネ電源（主に太陽光）の割当に依存するため、悪天候や日照不足で発電効率が下がると供給できる再エネ電力の残りが無くなり、その時間帯は選択できなくなります（/sources/ja/runbooks/escalation.md:55）。一方Economyは設置先の電力契約の電力をそのまま使うため、この影響を受けず選択できます。なお2025年11月までの「純再エネ」メニューは栃木県内5か所など自社発電所からの供給が中心で、天候や需要の状況により、ご利用になりたいタイミングで十分な再エネ電力を供給できない課題がありました。現在は非化石証書の外部調達を組み合わせ、再エネ100%を安定的に確保する「再エネメニュー」の仕組みに移行しています（/sources/ja/public-help/articles/52372068113689.md:20-28）。

解消時期について
申し訳ありませんが、ご利用の拠点でRegular／Premiumがいつ選択可能になるかについて、公開資料には拠点別の復旧時期や恒久的な解消日の記載がなく、正確な日程はご案内できません。当面は予約可能なメニューでのご利用、または周辺拠点のご確認をお願いいたします。恒常的に選べない状況が続くようでしたら、拠点名と日時（可能であればメニュー別の表示状況）をお知らせください。確認担当へ申し送りのうえ、状況をご連絡いたします。
